SUPPLEMENT COOLANT ADDITIVESUPPLEMENT COOLANT ADDITIVEThe coolant additive should be used with heavy duty coolant, having aconcentration of 50% water mixture.Supplemental coolant additive (DCA4) concentration levels are dependentupon the presence of antifreeze to provide greater protection againstcorrosion, scale, and foaming. Antifreeze alone has insufficient additives forlong term protection.DCA4 coolant additive is available as a liquid or as a slow release coolantfilter. If DCA4 liquid is used DO NOT use a coolant filter that uses coolantadditives. The combination of liquid and filter coolant additives will resultin over concentration.Operators HandbookPublication No: 2138RECOMMENDED CONCEN<strong>TR</strong>ATION - DCA4CONCEN<strong>TR</strong>ATION DCA4 COOLANTMinimum - 0.33 units per litre 1 unit per 3 litresMaximum - 0.8 units per litre 2.4 units per 3 litresEXAMPLEVehicle system capacity 35 litres. 35 ÷ 3 litres = 11.6 units (minimum)Select nearest filter size 12 units (See parts manual).(Multiply by 2.4 to obtain maximum concentration - 27.8 units)Check the coolant additive concentration regularly with the DCA4 Coolanttest kit (Fleetguard Pt.

Reduction ofpressures below those identified for any given axle load is not permittedunless agreed by the tyre manufacturer.An increase of up to 10% in front tyre pressures may provide improved fronttyre life, particularly in urban conditions where sharp corners or roundaboutsare frequently encountered. However, this improved life may beaccompanied by a reduction in ride quality.Increasing the rear tyre pressures in isolation is not permitted on rearengined bus applications, as handling could be adversely affected.In case of doubt, reference should be made to Dennis EngineeringDepartment or the Technical Department of the tyre manufacturer.PageIntroduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2Contents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3Product Warnings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4General Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5Vehicle Identification . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6Vehicle Identification Sheet . . . . . . . . . . . . . . . . . . . . . . . 7Daily Maintenance Checks . . . . . . . . . . . . . . . . . . . . . . . 8 - 9Engine compartment layout . . . . . . . . . . . . . . . . . . . . . . . 10Lubricants and Fluids . . . . . . . . . . . . . . . . . . . . . . . . . . . 11Warning Light Panel . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 - 14Controls and Instruments . . . . . . . . . . . . . . . . . . . . . . . . . 15 - 18Suspension System . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19Starting and DrivingEngine . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20Automatic Gearbox . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 - 22Driving Downhill . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23Retarder Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23Stopping in Traffic & Parking . . . . . . . . . . . . . . . . . . . . . . 24Engine Shutdown & Engine Stop Control . . . . . . . . . . . . . 25Towing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26Battery carrier . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27Jacking points . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28Emergency Repairs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29Tyre Pressures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30Refuelling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 31Coolant additive . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3230 3

JACKING POINTSGENERAL DESCRIPTIONThe <strong>Trident</strong> bus chassis is equipped with jacking points on all three axles.The jacking points should always be used when carrying out vehiclemaintenance. The diagram below shows their location.Front axle location:Jack up under axle beam directly below chassis frame.Drive axle location:Jack up under rearmost suspension mounting plate.Auxiliary location:Jack up under axle spring clamp plate.The Dennis <strong>Trident</strong> is a three axle bus chassis, powered by an electronicallycontrolled 6 cylinder turbo charged diesel engine driving a portal rear axlethrough an electronically controlled three or five speed automatictransmission.The air operated braking system is powered by an engine-drivencompressor supplying five reservoirs through an air dryer which alsoregulates pressure. Service One and Service Two reservoirs each supply aseparate system for the brakes on the front, drive, and Auxiliary axles. Thepark reservoir supplies the spring-applied, air released brakes on the driveand Auxiliary axles. The Auxiliary reservoirs supply the air suspension andbody services such as the doors.The hydraulic system is powered by an engine driven tandem pump whichsupplies the steering box and cooling fan.The auxiliary axle suspension consists of trailing taper leaf springs, with apanhard rod. The front and drive axle suspension are multilink with anti-rollbars and supported by air springs and hydraulic dampers.The 24 volt electrical system is powered by an engine driven alternator andtwo batteries. The system supplies the usual lighting, warning and indicatingsystems. The engine electronics are served by a 12 volt supply.An electronically-controlled air system is installed which allows a kneelingsystem to operate. The kneeling system allows the front suspension airsprings to be deflated, to lower the entrance of the vehicle almost to kerblevel.28 5

DAILY MAINTENANCE CHECKSSTARTING AND DRIVINGBefore driving the vehicle the recommended following daily checks shouldbe carried out:• Hydraulic system reservoir level• Engine oil level• Check ride height• Air braking system• Electrical system• Windscreen washer reservoir levelHYDRAULIC SYSTEMThe hydraulic dipstick and filler is situated to the rightof the engine on the frame upright. The oil levelshould be checked with the engine idling. Maintainthe level between the High and Low marks.ENGINE OIL LEVELThe engine oil dipstick is situated at the rear of thevehicle with the oil and fuel fillers. The correct oil levelshould register between the High and Low mark.Never operate the engine with the oil level below thecross hatched area or above the full mark. Wait atleast five minutes after stopping the engine to checkthe oil level, this allows the oil to drain into the sump.COOLING SYSTEMThe coolant level gauge is sighted at the rear of thevehicle. The coolant should be checked when theengine is cold or after 15 minutes if the vehicle hasbeen running The level should be maintained at themaximum level. If topping up is required use a 50/50mix of good quality water and antifreeze (see coolantadditive)ENGINE SHUTDOWN• Apply the handbrake.• Allow the engine to idle for a few moments to allow even cooling.• Turn the ignition switch to OFF O.• Turn off the master switch. This must not be done before the enginehas stopped.EMERGENCY STOP CON<strong>TR</strong>OLThe engine emergency stop button issituated at the rear of the vehicle andmounted in the side of the rear junctionbox. The engine can be stopped atanytime regardless of vehicle condition.The vehicle can be restarted from thejunction box, but the parking brake mustbe on and neutral gear selected beforethe vehicle will start.A second pair of stop / start switches arefitted in parallel to the junction box pair.Refer to the body builders literature forthe switch location.CAUTION! Allow the system to cool sufficiently beforeremoving the header tank filler cap as failure to do so cancause personal injury from heated coolant spray.8 25
STARTING AND DRIVINGDAILY MAINTENANCE CHECKSSTOPPING IN <strong>TR</strong>AFFICDuring short stops at traffic lights etc, the gearbox need not be returned toneutral, but the vehicle brake should be applied gently to prevent the vehiclefrom creeping forwards.During long stops, the neutral (N) button should be selected and and thehandbrake applied.PARKINGCAUTION! Since the clutches and brakes in the gearbox aredisengaged when the engine is stopped, there is no directmechanical link between the engine and driven road wheels.Therefore it is essential to apply the parking brake whenleaving the vehicle. In addition, it is good practice on slopes tochock the wheels, thus ensuring that the vehicle cannot rollaway.STOPPING THE ENGINEThe vehicle can be stopped at any time, regardless of the selector position.As the vehicle comes to a halt the automatic control will shift down to thecorresponding ratio for restarting depending on the drive range.WARNING! Never change from neutral (N) to drive (D) orreverse (R) at engine speeds above idle. The vehicle will lurchforwards or backward and the transmission will be damaged.AIR BRAKING SYSTEMCheck that the low air buzzer comes on with theignition and goes off once the vehicle is started andthe air pressure builds up.Check the satisfactory operation of the parkingbrake.Check that the correct pressure is indicated on theair pressure gauges, and they are not registering inthe red sector.ELEC<strong>TR</strong>ICAL SYSTEMCheck the operation of all lights, switches, warninglights, direction indicators, stop lights and the horn.Check that the alternator is charging correctly.Check that instruments are working correctly.VOITH GEARBOX OIL LEVEL - WEEKLY CHECKTo check the gearbox oil level the vehicle must be onlevel ground with the parking brake applied and atoperating temperature. With the engine idling andneutral 'N' gear selected, remove the dipstick andclean. Insert the dipstick briefly to prevent a falsereading from oil splash. The level must bemaintained between the "max" and "min" level.RIDE HEIGHTCheck visually to ensure the vehicle is sitting level.24 9
DAILY MAINTENANCE CHECKSSTARTING AND DRIVING(SPEED RANGES CONTINUED)1This gear is used when pulling through mud and snow or drivingup steep gradients. This position also provides maximum enginebraking power.NOTE: If the bus fails to move off, you may have forgotten to press "N"when starting the engine or you have stepped on the accelerator orforgotten to press the brake pedal when selecting a gear. Try again: takeyour foot off the accelerator, press the footbrake then press button "N" andafterwards button "D".DRIVING DOWNHILLSelect a suitable gear ratio before reaching the downhill gradient and reducespeed so that the gearbox shifts down to the highest ratio of the rangeselected. This will prevent the gearbox from shifting back to a higher speedrange automatically.RETARDER OPERATIONThe transmission has a convertor brake or retarder, and suffers nomechanical wear. This saves wear on the service brakes and in anemergency the full braking effect (no fading) of the service brakes isavailable.Engine Compartment LayoutThe brake pedal has three stages of operation according to the position ofthe pedal. The first two positions apply a first and second stage of braking.The third position will apply the vehicle brakes in addition to the retarder.The brake pedal has three stages of operation according to the position ofthe pedal. The first two positions apply a first and second stage ofbraking. The third position will apply the vehicle brakes in addition to theretarder.No special equipment is visible in the drivers cab, except a retarder warninglamp which illuminates when the retarder is in operation.10 23
STARTING AND DRIVINGLUBRICANTS AND FLUIDSSPEED RANGESThe transmission will prevent a change into any range at a speed which willcause the engine to over speed. Any lower range may be selected atanytime, but will only engage when the road speed is reduced. The inhibiteffect will cause changing down to occur at a slightly higher speeds thannormal.NOTE: The vehicle is fitted with a Gearguard system. When selecting agear depress and hold down the footbrake, then select the gear on theselector.RND2 or 3WARNING! Do not allow the vehicle to coast in neutral. Thispractice can result in severe transmission damage. Also noengine braking is available.REVERSE: Before selecting reverse, the vehicle must becompletely stopped. When changing from Drive to Reverse orReverse to Drive, the Neutral button must be pressed first.Never engage Reverse gear when moving Forward.. To preventaccidental engagement. the reverse interlock button must also bepressed when selecting reverse. This selection has the greatesttractive advantage.NEU<strong>TR</strong>AL: Use this position when starting the engine. If theengine will start in any other position, the auto cut-out is notworking. Neutral should also be selected when experiencinglonger than normal periods of idling. For short stops at trafficlights etc the selected button remains depressed and the vehicleis held by the handbrake.DRIVE: This is the normal forward gear. When the accelerator isdepressed, the vehicle will move off in first gear and change upautomatically through 2nd and 3rd to top gear as the speedbuilds up. When the vehicle slows down, the transmission willchange down into the correct gear automatically.If the road or traffic conditions make it desirable to prevent thetransmission changing into higher gear, 3 should be selected tolimit the range to 1st and 2nd.and 3rd or 2nd to limit the range to1st and 2nd. When conditions improve, return the selector to theD position. This position provides progressively greater enginebraking power.Vehicle Capacity General RecommendedComponent In litres Specification Brand(approx)1 Engine 35.5 API - CF-4 SG & CG-4SH Total Rubia 440015W-40 15W-402 Gearbox - Voith 19.0 Dexron III Total Fluid IIIOil change 15.0 Total Fluid XT3 Drive Axle 13.5 AP1 GL5 Total EPB85W / 1404 Auxiliary Axle A/R Multi purpose Total Multis EP25 Cooling System 54.5 Water/Antifreeze Total50/50 Mix Universal Antifreeze *6 Power Steering 19.0 Dexron III Total Fluid III& Fan Drive system7 Steering Column 0.05 Dexron III Total Fluid III8 Grease:Steering shaftAxle swivel pins A/R Multi Purpose TotalBattery carrier slide Lithium Based Multis EP29 Drive shaft A/R Lithium based Total MultisComplex EP2* Supplementary coolant additive is also required.22 11
WARNING LIGHT PANELSTARTING AND DRIVINGNote:The following section lists all of the warning light options that areavailable. However each vehicle will carry only the requirements thatwere specified. Therefore the warning lights should be carefullystudied during the vehicle familiarisation.SHUTTING DOWNAfter operation, allow the engine to idle for 3 - 5 minutes before shutting offto allow the oil and coolant to remove heat from many parts, especially theturbocharger. To stop the engine, turn the ignition switch to OFF.Check List Before Moving Off• Check that the air pressure reading on both gauges is not in the redsector.• Check that the engine is idling satisfactorily.• See that no warning lights are showing except the handbrake.AUTOMATIC GEARBOX1.
