Info

allows for a quicker release than a standard GM bearing. This bearing is designed to fit the stock GM release arm. On Chevy engine conversions retaining your stock Toyota 4 speed, the stock release bearing is a 2-piece setup - a collar that connects to the release arm and the bearing. The stock bearing must be removed from the collar and Part No. 716314 installed in its place. This bearing diameter has a radius face and is similar to the stock Land Cruiser bearing. This bearing is supplied in our kit as well as the Mark’s 4WD adapter kit. On the inside of the bearing collar, you will find a small cavity that must be packed with grease to ensure smooth clutch operation. On Ford engine conversions retaining the stock Toyota 3 speed transmission or upgrading to a Ford transmission, release bearing P/N 716311 will be required. When retaining your stock Toyota 4 speed with a Ford engine conversion using the Mark’s 4WD adapter kit, the kit will be supplied with release bearing P/N 716313. Both these bearings are flat-face and are designed to work with the Centerforce high diaphragm pressure plate. Stock Stock Land Land Cruiser Cruiser 4 4 Speed Speed Conversions: Conversions: 1974 model Land Cruiser owners will be required to purchase a new release bearing collar. The original collar is too small to be used with the new release bearing that is being provided in the 4 speed conversion kits. On these early 4 speed applications, you will need to purchase the two Toyota part numbers listed below. Toyota# 31231-60070 - Bearing Collar (2.062” Dia.) Toyota# 31232-60010 - Bearing Collar Clips (2 Required) CLUTCH RELEASE LEVERS: When using a standard GM bellhousing, we recommend the stock GM cast iron release arm, P/N 716176 (GM# 15687296). On Ford applications, the stock release lever from your Ford bellhousing should be used. Applications retaining the stock 4 speed using our bellhousing or Mark’s 4WD bellhousing will retain the stock Land Cruiser release arm. On a Land Cruiser 4 speed conversion, the lever will protrude on the passenger side. When using a GM or Ford bellhousing, the release lever will protrude on the driver's side. In order for the Toyota slave cylinder to properly disengage the GM release arm, you must fit the Toyota push rod into the inner slot of the release arm. This will provide additional movement of the clutch release lever.

On Chevy V8 conversions, the original GM pilot bushing diameter will require no changes since it is compatible with the Toyota 3 & 4 speed transmissions. On Ford V8 conversions to the stock Toyota 3 & 4 speed transmissions, you will need to install the new pilot bushing supplied with your kit. When using a GM 4 speed transmission with the stock Land Cruiser 6 cylinder engine, you will need to install our special pilot bushing into the 6 cylinder crankshaft.

On Toyota Land Cruiser conversions, you must use a specific pressure plate and clutch disc. With the help of Centerforce Clutches, we have developed a clutch assembly that operates perfectly with the original Land Cruiser slave cylinder and master cylinder. This pressure plate is a short throw, quick ratio, diaphragm-type pressure plate that requires very little slave cylinder movement. We stock the Centerforce clutches as standard items and they can be obtained from us directly. If the correct clutch is not used, you may experience inadequate clutch disengagement. 20 CLUTCH COMPONENTS
Under no circumstances should you EVER reuse the original Toyota clutch disc with these recommended pressure plates. Be sure to align the clutch disc with the pilot bearing prior to assembling the pressure plate to the flywheel. A clutch alignment tool is available for this procedure from most auto part stores. In the 20 plus years that we have been performing V8 engine conversions into Toyota Land Cruisers, the most common problem that we encounter is that the customer does not select the proper clutch assembly for use with the Toyota slave cylinder. For your clutch to operate properly, please verify that the correct clutch components have been selected. We highly recommend using the Centerforce clutch components listed below. This combination is proven to work with the Land Cruiser hydraulic clutch system. If clutch components of other manufacturers are used, we cannot guarantee proper clutch operation.

On earlier applications, you must change the flywheel and clutch fork to use these clutch assemblies. Photo courtesy of William Leaman and taken at Guardrail hill in Tellico, TN.
