Manual Gearbox - 3 Synchro Internal Components

Welcome to Somerford Mini Ltd. 

Somerford Mini Limited was established in 1990 by Peter Hines, a Mini enthusiast. The 

company has been very successful and now boasts a huge spares department alongside 

the original restoration business. Manned by restorers with a deep passion for (and vast 

knowledge and experience of) the Mini, our workshop enjoys a reputation as one of the 

country’s leading Mini restoration centres. With the spares and restoration departments 

together as a team, we have the full blessing of MG Rover, through being a British Motor 

Heritage Approved Specialist. We are justifiably proud of this accolade. 

The spares side of the business started in 1994 and has grown at an incredible rate. We 

now stock over 8000 lines, with more being added all the time. We cater for all Minis, 

from 1959 to the end of production in 2000, with the parts needed to carry out a full 

restoration, including very specialised body fittings that are not otherwise widely 

available. Other stock ranges from service items right the way through to accessories, 

performance parts and all the latest gizmos to dress up your Mini. 

Somerford Mini Limited is still a small enough company to guarantee a personal service, 

a very important consideration. Unlike many of our competitors, we can offer proper 

advice before you make your purchase. We know from our own workshop experience 

what works and what doesn’t, so if you’re not sure about something please ask – the 

chances are we can help. Our workshop is also able to fit any part we sell, if you so 

choose. We take a pride in being totally honest with our customers and not making 

false promises (tales of which you hear only too often with some mail order companies). 

We look forward to helping you to care for your cherished Mini.

Ordering Parts 

When ordering parts, it is very helpful if you also provide us with information about 

your car. Details such as the chassis number (or vehicle identification number on 

later models), engine number, year of manufacture, whether the car is right or left 

hand drive and details of any modifications will all help to ensure you get the parts 

you need. 

You can order parts by telephone, fax,mail, e-mail, through our website, or 

alternatively you would be most welcome to visit our shop during normal trading 

hours (Monday to Friday 9.00am to 6.00pm, Saturday 9.00am to 2.00pm, Sunday 

closed). We provide a range of methods of despatch for your order, from regular 

post through to next day courier delivery. Sometimes the method of despatch is 

dependant on the weight or size of your order. We are of course happy to give you 

a quotation, including delivery costs, before you place your order with us. 

Using This Catalogue 

Illustrations and Illustration Numbers: The illustrations are carefully 

crafted to guide you to the parts you want for your car. Each assembly is depicted 

in an exploded format and for consistency,where practicality permits, the view is from 

a left hand front three quarter angle (we’re also aware that many customers use 

catalogues as a visual guide to the assembly procedure of their car!). If only one hand 

is illustrated of a part with right and left hand versions, both hands will be listed under 

the matching illustration number in the text, usually with the right hand listed first. 

Part Number: A part number is the identifying name for a part in our stock 

control system, and differentiates between versions – right hand or left hand, early or 

late model. We ask you, where you can,to use part numbers when ordering – it helps 

to guarantee you get the exact parts you need. If you can’t work out which part 

number or you’re having difficulty working out exactly what it is you need, please 

contact us. We are only too happy to guide you or work it out for you. 

Description: We need to clarify here what we mean by right and left hand. Right 

and left hand is always taken from a viewpoint of sitting in the car,not from standing 

in front of it. So why don’t we say ‘offside’ or ‘nearside’ Because offside for a right 

hand drive car is nearside for a left hand drive car (you can see how this becomes 

easily confused…). 

Quantity Required: This is always the quantity required per car. For example, 

if two bolts hold a hinge, and there are four hinges on the car, the quantity required 

will be shown as 8, not 2. 

Remarks: This is additional descriptive information to help you identify the part 

you need, to tell you exactly what you’ll receive if you order that part, or to make you 

aware of an available alternative. It does this by telling you to which models or in 

which years a part was originally fitted (if there is a choice), or what that part includes, 

or whether that part can be used on other models. 

Parts Availability 

While the great majority of the parts listed in this catalogue are currently available, 

there are some that are not. A few of the parts shown in this catalogue are there in 

anticipation of what may become available in future (new or reintroduced products are 

constantly under development). A handful of others are there to historically acknowledge 

what would have originally been fitted and are, where possible, accompanied by an 

alternative, serviceable product. It therefore follows that this catalogue does not 

constitute a definite offer for sale of any particular item. 

In the accompanying price list, a price beside the part number indicates that the part 

is usually available; if the part number is absent it indicates non-availability. If the 

comment ‘use’ (followed by a different part number) is found, the original part has been 

superseded by an available alternative. 

Overseas customers should note that sometimes shipments will be subject to local 

import duties, which are not included in the price we charge for your order, or the 

delivery costs. These duties must be paid by you before you can receive your 

shipment. Value Added Tax at the current United Kingdom rate will be levied on all 

orders despatched to countries within the European Community, but will not be 

levied on orders despatched to the rest of the world. 

We accept payments for orders by cash, personal cheque, bank draft, Sterling 

travellers cheque and most credit or debit cards, including Visa,Mastercard, Maestro 

(Switch) and Delta. If you intend to pay by personal cheque or bankers draft, we 

would advise you to ask for a parts availability check and quotation before placing 

your order.

Change Points 

In the catalogue you will see parts changes referred to by dates. We have steered away 

from the tradition of listing change points by chassis or commission number (they’re 

different,and the factory parts books used both) because they are so complicated on 

Minis. All the models had different change points until 1984 (after which it got much 

easier) and to list change point numbers often amounts to half a page of text! 

better town car, which in some other respects it undoubtedly is. Also, refinement is not 

the automatic’s greatest feature; it changes gear rather a lot (often downwards), 

subjecting the car’s occupants to even more noise than in a manual Mini. 

It is surprising that the innovative and promising Mini automatic was largely starved of 

development during its 35 years in production, major changes being confined to the the 

gearchange mechanism, plus the introduction of A Plus drop gears in 1982. 

As a result, we’ve used years instead. While much more simple, we acknowledge that 

using dates to portray change points is not perfect. For example, you will know the 

year of registration of your car but you might not know the year of manufacture - the 

two aren’t necessarily the same. Also, a revised part was often introduced during a year 

rather than at the beginning or end of it. If you have difficulty in establishing which 

part is for your car,you will find a list of Mini models production history at the end 

of this catalogue which may help. If it doesn’t, contact us, preferably with your chassis, 

commission or engine number to hand, and we’ll do our best to sort it out for you. 

Mini Transmissions 

The manual gearbox created for the Mini in 1959 was an essential factor in the 

amazing space efficiency of the car. Developed from the gearbox used by BMC’s other 

A Series-engined cars of the time like the Morris Minor (and sharing many of the 

gearbox internals), the Mini gearbox was the first to be positioned under the engine. 

This allowed the entire power unit to be mounted transversely in the car, keeping the 

area occupied by it to a bare minimum. 

Gear selection was made by a long gear lever (‘direct change’), remembered affectionately 

as the ‘magic wand’ or ‘pudding stirrer’ by those who owned early Minis. Power was 

transferred from the engine and clutch down to the gearbox via a series of three gears 

colloquially referred to as the drop gears; the design initially allowed oil onto the clutch 

all too frequently, causing severe slippage. The sealing system had to be quickly 

redesigned and a programme was carried out to modify the Minis built thus far. 

After this hiccup the Mini gearbox settled down to a reasonably trustworthy existance. 

It was, however,still subjected to many improvements through the years and apart from 

the basic shape of the gearbox case very little of the 1990s Mini gearbox is recognisably 

the same as that on early cars. 

Most of the modifications centred on improving the gearchange - a remote gearchange 

arrived in 1961 (for several years fitted only to Coopers, it had the additional benefit 

of considerably steadying engine movement), cone synchromesh gave way to baulk rings 

in 1962, a proper synchromesh gear replaced the old ‘crash’ first gear in 1968 and the 

remote gearchange plus the gear selectors were replaced by a system known as ‘rod 

change’ in 1973. 

Two other major design modifications are worthy of note, both involving quietening the 

gearbox. Around 1963-64 the angle of the gear teeth was changed (post-modification 

gears being known as B Type and pre-modification retrospectively becoming A Type). 

This happened again around 1982 (the new gears being known as A Plus), bringing the 

Mini gearbox in line production-wise with the recently introduced Austin Metro. Exact 

identification of a Mini manual gearbox prior to replacement of gears is therefore of 

paramount importance - different angled gear teeth will not mesh together! 

Automatic transmission arrived in the Mini for 1965. A special automatic specification 

engine block had to be cast, a fact not lost on Mini owners who have converted their 

cars from automatic to manual and had to change the engine as well as the gearbox. 

The Mini automatic has significantly worse fuel economy as well as poorer acceleration 

than that managed by manual Minis, detracting from the automatic’s claim to be the 

Opinions concerning Minis fitted with automatic transmission entrench the enthusiast 

fraternity, the vast majority believing that the only good thing you can do with an 

automatic Mini is to convert it to manual. Yet the automatic Mini still does have its 

supporters, not least in Japan, the Mini’s biggest market in the 1990s, where nearly all 

of the Minis sold were automatics because of that country’s highly congested city roads.

Verto Clutch Types, 1982 On 

The Verto flywheel and clutch assembly was introduced as a means of lightening the effort required to 

operate the clutch (the older diaphragm clutch was a very strong and reliable design which 

unfortunately required an agricultural stomp of the foot, quite unbecoming in a new car by the 1980s, 

to operate it). 

As replacement par ts, Verto clutches were originally only supplied as balanced assemblies complete with 

flywheel, in an attempt to counter clutch judder in service. Nowadays, you can purchase the clutch 

components separately if you wish, but the flywheel is still only available as part of the (rather steeply 

priced) flywheel and clutch assembly.

Clutch Components 

Coil Spring Clutch, 1959-64 

At time of writing, components for the coil spring clutch fitted between 1959 and 1964 are hard to 

come by, to say the least. The later design diaphragm housing and/or clutch plate can be used to 

repair or replace a coil spring clutch in some instances: however by rule of thumb, the earlier the 

flywheel and crankshaft, the less likely this will be possible. On 1963-64 flywheels, it’s a straight 

replacement of coil spring clutch parts by diaphragm clutch equivalents. 1962-63 flywheels (i.e. those 

with the 1 3/8" machining for the Deva bush) will accept a diaphragm type clutch plate, but not a 

diaphragm housing. 1959-62 oil-fed bush type flywheels (can’t be many of these left now, surely - most 

were replaced with Deva flywheels in the 1960s) will only accept coil spring clutch components. If you’re 

unlucky enough to need to replace the clutch on one of these, a crankshaft, primary gear and flywheel 

swap will be required - or an engine swap,which might be cheaper and w ould certainly be quicker. 

Please contact Somerford Mini if you require replacement parts for a coil spring clutch assembly, 

giving us if possible as much detail as you can about the dimensions of the flywheel to which the 

clutch is to be fitted. The following are the original components for coil spring clutches:

Interchangeability of flywheel housings: 

For 1959-68 models (3 synchro gearbox), none of the later 4 synchro flywheel housings can be used in 

place of the original. 

For 1968-79 models (not 1275), flywheel housing DAM6259 may be used, so long as the special idler 

bearing with sleeve DAM3745 is also fitted. 

For 1968-69 models (1275 only), flywheel housing DAM6259 may be used, so long as the special idler 

bearing with sleeve DAM3745 is also fitted. 

For 1969-79 models (1275 only), flywheel housing DAM6257 may be used, so long as the special idler 

bearing with sleeve DAM3745 is also fitted. Alternatively, flywheel housing TRD10015 may be used, so 

long as LCG10001 crank sensor hole blanking plate and two off FS105101 screws are also fitted, along 

with the special idler bearing and sleeve DAM3745. 

For 1979-91 models (1275 carburetter), flywheel housing TRD10015 may be used, so long as LCG10001 

crank sensor hole blanking plate and two off FS105101 screws are also fitted. 

These notes show how to use later flywheel housings on earlier 4 synchro power units - they do 

rely on the original idler gear being retained. If you’re not sure what’s original on the car for 

its year, to be sure you may have to dust off a vernier caliper and deduce (i) the external 

diameter of the idler gear bearing required (measure the bearing location in the flywheel housing) 

and (ii) the internal diameter required (measure the idler gear shaft diameter). You should then 

be able to find a bearing size suiting your purposes from the Somerford Mini range above.

17 RCLIP01 ‘R’ CLIP 1 Easier to fit than a split pin! 

Fitting the split pins to the top of the clutch and brake pedals to connect them to their 

respective master cylinder push rods is one of those classically frustrating jobs on a Mini - you 

know the score: a half minute job that takes half an hour because there’s so little space in 

which to manoeuvre! You can see where the split pin goes until you get your hand and a pair 

of pliers in there, after which you can’t see what you’re doing and there’s no space to turn over 

the ends of the split pin anyway. An ‘R’ clip however can be inserted in place of the split pin, on 

the end of a pair of thin-nosed (‘snipe-nosed’) pliers, and simply clips in place without a 

struggle. This is positively the easiest, most gratifying modification you’ll ever make to your Mini!

Clutch Master Cylinder 

The vast majority of Minis used the same metal tank clutch master cylinder (which could have either of 

two internal designs - watch out and carr y on reading below if you need a repair kit). This was 

superseded in 1998 approximately by a plastic tank version, which saw use until the end of Mini 

production in 2000. While metal and plastic tank master cylinders are theoretically interchangeable, 

most owners seem to stick with the style appropriate for their car. 

Around 1977 the manufacturer of the metal tank master cylinder changed the design of the piston 

inside to incorporate two ring seals instead of the previous one ring seal and one cap (or blind) seal. 

Most - but not all - metal tank master cylinders available since that time are of the later design, which 

may be identified by a circle or groove cut into the body of the cylinder. The very late-model plastic 

tank master cylinder also uses the ‘two ring seal’ piston design. Be sure to identify which cylinder you 

have before ordering internal parts for it from Somerford Mini!

Manual Gearbox - Primary, Idler and 1st Motion Shaft Drive Gears

Manual Gearbox - Primary, Idler and 1st Motion Shaft Drive Gears 


Primary, Idler and 1st Motion Shaft Drive Gears 

Several different combinations of primary gear and bushes were used on the ear liest Mini power units 

built between 1959 and 1963, following the abject failure of the first, the so-called ‘D.U.’ bush and oil 

seal design (which allowed engine oil seepage onto the clutch all too frequently). As an interim 

measure, a revised oil-fed bush system was fitted - in most cases when the car came in for the 

inevitable clutch replacement - and after a couple of false starts the ‘Deva’ dry-lubricated bush became 

the standard fitment. Each system necessitated a different engine crankshaft and flywheel, as well as 

the primary gear and bushes. Extra care must be taken to select matching components for these ear ly 

designs. 

From 1963 onwards, crankshaft, flywheel, primary gear and bush combinations settled down into tw o 

designs, depending on the crankshaft tail dimensions: one combination for 848, 998 and 1098 engines 

and the other for 1071, 1275 and 970 engines. This continued right the way through to 1979 when ‘A 

Plus’ gears were introduced, which saw production out through to 2000. 

Primary gears are supplied with their bushes fitted, as ready-to-use assemblies, from Somerford 

Mini. However, if you intend to fit replacement bushes in a primary gear, the bushes must be 

machined after fitment to ensure alignment with each other. 

By contrast, the idler and 1st motion shaft drive gears saw far fewer changes, being limited to 3 

synchro gearbox (1959-68), pre-A Plus 4 synchro gearbox (1968-79) and A Plus (1979 on). Of these, 

pre-A Plus 4 synchro gears may be used on 3 synchro gearboxes if certain other components are fitted 

at the same time. However, pre-A Plus and A Plus gears cannot be mixed and matched together. 

Bearings (and their retaining circlips) for the idler and drive gears may be found in the ‘Flywheel 

Housing and Clutch Cover’ and ‘Manual Gearbox - External’ sections of this catalogue. Primary, idler and 

drive gears for automatic Minis may be found in the ‘Automatic Transmission - Torque Converter and 

Housing’ section. 

Primary Gears 

Confusion often reigns over the convention for naming primary gear bushes. Which should be called the 

front bush and which should be the rear The answer is the bush closer to the front of the engine 

(i.e. the water pump end) is the front bush and the bush on the clutch end (the ‘top hat’ bush on 

post-1962 cars) is the rear bush. Hope that sorts it out.

Manual Gearbox - External Components 


Rebuilt or Repaired Gearbox Assemblies 

Somerford Mini Ltd. offers a gearbox rebuilding and repair service through its workshop facility. We can 

carry out repairs or rebuilds on late-model gearboxes, but can only realistically offer a repair service for 

the earlier designs because of, frankly, poor overall par ts availability in the marketplace. Please 

contact us to discuss your Mini gearbox requirements - it would be helpful if you could supply us not 

only the details of what’s gone wrong with your gearbox, but the age (if known) and type (3 or 4 

synchro, A or A Plus, gearchange type and driveshaft type). The more you can provide us with, the 

better we can ascertain how we might possibly help you. 

It has to be said that at time of writing, spares availability for 1959-68 3 synchromesh gearboxes is not 

very good at all and unfortunately because of the high cost involved in reintroducing some components, 

the situation is unlikely to get much better in the forseeable future. Rest assured, however, that we will 

always do whatever we can to help you. The later 4 synchromesh gearboxes fare much better, especially 

of course the rod change variety which were in production between 1973 and 2000. Having said that, 

there are some surprising gaps in parts availability, even for 1980s rod change gearboxes. 

The general rule is that the older the gearbox type, the more components are not available new and 

the less likely a totally comprehensive rebuild will be possible. 

5 Speed Gearbox Assemblies 

5 speed rod-change gearboxes have generated much interest for some years now, with several 

organisations producing their own designs (Jack Knight Developments, KAD and Mini Spares, for example).

Selector shaft oil seal failure was always a problem on rod gearchange Minis (as any late-model Mini 

owner with oil drips on their garage floor will know). The most common remedy effected by owners in 

the past was to put two oil seals one behind the other on the selector shaft (there’s just enough space 

to do so),the outer one of the two acting both as a secondary seal and also as a secondary shield 

behind the gaiter,protecting the inner seal from under-body muck and grit. Most importantly, the 

second seal helped to support the selector shaft and hold it in alignment in the gearbox casing. 

Factory engineers finally came up with a remedy in 1985,fitting a modified selector shaft bush with a 

new O ring to improve the selector shaft alignment. Somerford Mini of course supply all these 

parts separately, but we’ve also put them together as an easy-to-buy, easy-to-fit kit for the owner 

to modify a pre-1985 Mini or repair a later model.

Manual Gearbox - 3 Synchro Internal Components 


12 




The 3 Synchro Gearbox 

1959-68 

Fitted to all Minis between 1959 and 1968, the 3 synchro gearbox is so called because synchromesh is 

only available on 2nd, 3rd and 4th gears, 1st gear being of the ‘crash’ engagement type. Probably the 

most common fault on this gearbox is jumping out of first gear, followed closely by laygear bearing and 

layshaft failure. A proper first speed gear was inserted in the gearbox in 1968, at last receiving the 

great benefit of synchromesh engagement; this gearbox is known as the 4 synchro and its internal 

components are covered in the next section of the catalogue. 

If you’ve not been inside a 3 synchro Mini gearbox before or you can’t remember when you last did, 

please read these notes carefully - they could save you a lot of heartache. The gearbo x internal 

components were revised several times , with the changes being introduced at broadly the same times 

across all of the A series engined cars in the BMC range . Essentially, these revisions boil down to three 

types of gearbox (with a handful of components being awkward exceptions to the rule, of course... w e’ll 

explain those as best we can as we go along). 

The first 3 synchro gearbox fitted to the Mini is known as the ‘cone synchromesh’ gearbox, because of 

its use of cones to aid gearchanging rather than the more efficient baulk rings, which arrived in 1962. 

The next change occurred in 1963 or 1964 (depending on model) when the angles of the gear teeth 

were changed to quieten the baulk ring gearbox. The modified gears w ere known as B Type gears , the 

1962-63 gears retrospectively becoming known as A Type gears . So there you have it: 1959-62 Cone 

Synchromesh gearbox, 1962-63/64 A Type Gears gearbo x and 1963/64-68 B Type Gears gearbox (plus, in 

1963-64, an A Type gearbox with B Type 1st/2nd synchroniser and reverse idler...!). 

Gearbox Identification 

Identifying your 3 synchro gearbox can be a ver y complicated process, bourne out by the unfor tunately 

necessarily complex guidelines below. 

Between the three 3 synchro gearbox types, many, many components are not interchangeable. This 

makes it especially important to identify your gearbox before ordering par ts, which can be difficult, 

particularly when trying to work out whether you have A or B Type gears . Originally, gearbox cases 

were stamped with a part number denoting the gear types within and the model application; however 

this has become quite irrelevant over the years as gearboxes have been rebuilt, very often with different 

components to overcome the lack of original parts availability. 

The only surefire way to identify the gearbox nowadays is to inspect the internals with a check list to 

hand, paying particular attention to: 

(i) the presence of synchro cones or baulk rings (denoting a Cone Synchro box in the first instance and 

an A Type or B Type box in the second); 

(ii) If baulk rings are present, establish whether the second and third gears run on bushes (the bush 

interlocking ring being visible between the two gears on the mainshaft gear cluster) or bearings . A Type 

gearboxes except in the 1963 Cooper 997 run on bushes; the second and third gears in A Type 

gearboxes in the 1963 Cooper 997 run on bearings, as is the case with the similarly shor t-lived Cooper 

and Cooper S gearbox with hybrid A/B Type gears and all gearboxes with B Type gears. 

(iii) Count the number of teeth on the laygear cluster. A combination of 13/19/24/28 teeth is the 

regular set-up for non Cooper models and 13/19/23/26 for Cooper. Other combinations were available 

only as Special Tuning options. 

(iv) Are the laygear bearing circlips on the outside or inside of the bearings Cone Synchro and A Type 

gears except 1963 Cooper 997 use outside laygear bearing circlips, whereas A Type gearbox in the 1963 

Cooper 997, the hybrid A/B Type gearbox and B Type gearboxes use inside circlips. 

The laygear should tell you which combination of gears you have... we say ‘should’ because the laygear 

part number was traditionally stamped on the component between the lar gest and second largest gears, 

but some reproduction gears (mostly in the case of 22G1100) don’t have this stamping. Identifying 

your laygear allows you to work out what other gears have been used in the gearbox, since they were 

designed to go together as matched gear sets and are usually not interchangeable. For this reason, all 

the other major components in this section use the application remarks shown alongside the laygears - 

even if it’s a bit long-winded sometimes, it positively matches the sets together. 

Be careful with gearboxes in 848 models and 997 Coopers using A Type gears , though - some have been 

converted from cone synchro to baulk ring A Type gears, retaining the original laygear ; some other 

components used in cone to baulk ring converted gearboxes are unique and most are not listed here 

(this catalogue section is complicated enough!). The 22G1100 laygear,incidentally, was for a short 

period at the start of its life known as and stamped as 22G232. Lastly, if you find 22G83 or 22G714 

on your laygear, you have an Austin/Morris 1100 or 1300 gearbox, not a Mini one. 

Parts Availability 

Unfortunately, parts availability ranges from almost hopeless (Cone Synchromesh and A Type gears) 

through to pretty awful (B Type gears) and this situation is unlikely to improve greatly in the future. 

The B Type gears do, however, benefit marginally from the fact that the MG Midget continued to use 

versions of them until 1974, which slightly increases parts demand and availability. Many parts listed in 

this section are therefore shown only as a matter of reference. 

We will always do our utmost to help you seek out parts for your gearbox, but by rule of thumb the 

thing to remember here is don’t embark on a 3 synchro gearbox rebuild until (a) you’re absolutely sure 

you have the parts you need; and (b) you’ve weighed up seriously the benefits of sourcing another,better 

condition, gearbox instead. You have been war ned... 

Close Ratio and Straight Cut Gears 

Close ratio straight cut gear sets are available to build into gearboxes with B Type Gears components, as 

a special order. Please contact Somerford Mini for details. Similarly, please contact us if you have 

factory-optional (Special Tuning) helical close ratio, straight cut close ratio or straight cut 

standard ratio gears in your gearbox and you require replacement parts.

The 4 Synchro Gearbox 

1968 On 

Fortunately 4 synchro gearboxes are much easier to identify and classify than their 3 synchro 

predecessors (parts availability is considerably better, too, but not brilliant in some areas). The two 

main changes are the modification of gear shafts and several of the bearings in 1979, and A Plus gears. 

A Plus gears were pro gressively introduced, the bulk of models changing over around 1982. The y have 

a sharper tooth angle and different pitch making them quieter than the earlier gears, with which they 

are not interchangeable. A Plus gears may be identified by the presence of a circumferential groo ve in 

the centre of the teeth, plus flush machining on both sides of the final drive pinion. 

The following summaries help with identification and give you points to watch for when ordering par ts:

When reassembling the gearbox, ensure that the fork locating screws are securely locked in place. It’s 

not unknown for one of them to vibrate loose otherwise, allowing a fork to slide on its rod and 

resulting in a complete loss of ability to select the gears operated by that fork; removal of the engine 

and gearbox from the car to tighten up one screw is a painful lesson indeed. 

Somerford Mini remembers one occasion where two valiant souls entered in the Italian Job event 

drove their Mini right the way through the Alps and most of the way across northern Italy in 

first and second gears only, the third/fourth selector fork screw having worked loose! The engine 

and gearbox duly removed in an Italian hotel car park, the screw was retightened allowing the 

Mini to return across Europe to Britain under its own steam and with a full complement of 

forward gears (which no doubt allowed the drivers’ hearing to recover somewhat).

Manual Gearbox - Direct and Remote Gearchanges 


Direct and Remote Gearchange 

Direct gearchange (where the gearlever disappears through the toeboard straight into the back of the 

gearbox) was the system the Mini star ted with back in 1959. Its fitment was interspersed with the 

remote gearchange system (where the gearlever emerged from the end of a long aluminium casting 

under the floor) through the 1960s to the early 1970s - by rule of thumb, more upmarket Minis got 

the remote gearchange while more basic models (i.e. lowly 850s) carried on with the direct version. 

Calling it ‘direct’ was probably a bit of a misnomer, as the nicknames of ‘Magic Wand’ and ‘Pudding 

Stirrer’ hinted that in practice changing gear was not alwa ys that direct... 

While the direct and remote change systems are very obviously totally different, they share the same 

gear selector mechanism inside the gearbox. From late 1968 when the gearbox went over from 3 to 4 

synchromesh, they shared the same differential housing too - prior to that, the direct gearchange had 

its own unique diff housing with a small gearchange tower on it. 

The later rod change system (see the next section for details) required a complete redesign of the gear 

selector mechanism. Saloons and Estates were re-engineered for rod gearchange for the 1973 model 

year. Vans and Pick Ups however did not lose their direct gearchange in favour of rod change until the 

end of 1975.

Austin/Morris 1100 saloon of the period,but without the rubber ‘sandwich’ mounting used on those cars. 

This side-attached remote housing is not referred to in any of the factory parts catalogues, but - guess

Manual Gearbox - Rod Gearchange

Manual Gearbox - Rod Gearchange 


Rod Gearchange 

Introduced for 1973 on Mini Saloons and Estates and for 1976 on Vans and Pick Ups, the rod change 

system was simpler (kept the production engineers happy) and therefore cheaper (happy accountants), 

more robust (happy owners) and easier to use (ditto) than the previous choice of direct or remote 

gearchange. The ‘modified Mini’ frater nity mourned the loss of positive location offered by the outgoing 

remote system’s beefy casting, but soon welcomed the extra space inside the gearbox case which just 

about allowed the dream of a five speed Mini gearbox conversion to become reality. 

The success of the rod change gearbox led to it being used virtually without modification for the last 

27 years of the Mini’s 41 year production life.

Torque Converter Gear Train 

Note if you have a 1965 or early 1996 Mini Automatic that the output gear train is unique and is not 

itemised here. Factory advice for these models is to replace all three gears with those shown here, 

together with the relevant thrust washers and shims . 

If you are unsure that the age of your Mini’s transmission matches the age of the car, you will need to 

work out whether you have pre-A Plus or A Plus output gears. A Plus gears were introduced on the 

Mini round about 1982 (at different times on different models...), and have a sharper tooth angle and 

different pitch making them quieter than,but definitely not interchangeable with, the earlier gears. A 

Plus gears can be identified by the presence of a circumferential groove in the centre of the teeth.

39 22G109 BUSH, primary gear, rear 1 ‘Top hat’ bush. 

Once fitted, the primary gear bushes must be machined to ensure alignment with each other. Confusion 

often reigns over the convention for naming primary gear bushes. Which should be called the front bush 

and which should be the rear The answer is the bush closer to the front of the engine (i.e. the water 

pump end) is the front bush and the bush on the torque converter end (the ‘top hat’ bush) is the rear 

bush.

Automatic Transmission - Transmission Components 


Rebuilt or Repaired Transmission Assemblies 

Somerford Mini does not offer a rebuild or repair service for automatic transmissions other than 

superficial repairs not involving the internal workings, because of the cost of the necessary 

specialist equipment and the relatively few numbers of customers for automatic transmission work. 

We advise customers requiring rebuilds or repairs to deal directly with an automatic transmission 

specialist - we can point you in the right direction, if required. We should also mention we carry 

out automatic to manual power unit transplants in our workshops - automatic engines are 

unique and will not fit a manual gearbox, so both engine and transmission are changed. This 

apparently drastic measure actually frequently represents a very cost-effective way to get your Mini 

back up and running when otherwise faced with huge bills for automatic transmission repair. 

We do not hold comprehensive stocks of automatic transmission internal components. Instead we 

limit ourselves to parts which by our own experience we consider may be fitted successfully by our 

customers - and even then, sometimes only by the more e xperienced. As always, though, if there’s 

anything else you require, please contact us and if it’s available we will obtain it for you.

Final Drive (Differential)

Final Drive (Differential) 


Final Drive Assembly 

You will need to establish several things before embarking on a rebuild of your final drive: 

The first thing (and the easiest) is to work out which drive shafts your Mini has. Rubber coupling (or 

‘Moulton’) drive shafts were used on most Minis up until 1973. The exceptions were the Cooper S and 

automatic transmission models, which used universal joint (or ‘Hardy Spicer’) drive shafts up until that 

date. From 1973 onwards, all Minis used offset sphere (or ‘pot joint’) drive shafts. The designs of the 

final drive output shafts and their covers depend on the drive shafts fitted. While rebuilding a final 

drive on a rubber coupling Mini, you can easily convert it to take ‘pot joint’ drive shafts if you wish by 

fitting a pair of DAM3114 output shafts and 22G2688 circlips . 

The final drive gear also needs to be identified. This may be achieved by counting the number of teeth 

on the final drive gear and if you divide that number by the number of teeth on the corresponding 

final drive pinion in the gearbox, you’ll get the final drive ratio. If you are unsure whether the age of 

your Mini’s transmission matches the age of the car,you will also need to work out whether you have 

pre-A Plus or A Plus gears. A Plus gears were introduced on the Mini round about 1982 (at different 

times on different models...), and have a sharper tooth angle and different pitch making them quieter 

than, but definitely not interchangeable with, the earlier gears. Looking in the gearbox, A Plus gears can 

be identified by the presence of a circumferential groove in the centre of the teeth, and the final drive 

pinion on the gearbox mainshaft is machined flush on both sides . 

The only exception to this rule concerns cars with the 3.444:1 final drive ratio, which received A Plus 

final drive gears in 1979, a full 3 years before they got A Plus gearboxes. So, if you have a 3.444:1 

final drive Mini with a pre-A Plus gearbox containing the larger idler gear and 1st/3rd motion shaft 

bearings introduced in 1979, the chances are you will have A Plus final drive gears. 

Lastly, you will need to identify your differential case. The case was redesigned in the early 1980s to 

combat the problem of spinning pinion thrust washers wearing through it: notches were added to the 

case to locate anti-rotation tabs on redesigned thrust washers. 

For those indulging in modified or competition Minis, several flavours of limited slip differential and a 

stronger cross pin differential are available as special orders; please contact Somerford Mini to 

discuss your needs.

Brief Mini Production History 

This list is intended to assist some owners who are trying to establish year and model of their Mini. 

However, while the list may seem comprehensive, it isn’t. Just like everything else to do with the Mini 

when you look at its 40 year history, to come up with every last derivative, complete with corresponding 

chassis number (or vehicle identification number) prefix, would take several pages! However, limited 

editions excepted, it details the Mini models covered by this catalogue and is a fair representation of 

models down through the years. 

It does not cover models specific to certain markets that were locally assembled (e.g. Innocenti, Authi, 

Cord and Belgium, South Africa and Australia assembled vehicles). It also does not include certain shortlived 

niche models like the ERA Mini Turbo. 

Note that earlier MkI export models were often badged ‘850’rather than ‘Mini’ or ‘Seven’, and that the 

later 1980s/1990s City models were usually known in Europe as Special and in Japan as Sprite.
