The clutch disc should be centered using the alignment tool.

To remove the clutch release bearing, start by removing the release cylinder and then the transmission. On models like the 1994 and 1995 models, the bell housing needs to be removed. Once removed, detach the clutch release lever from the ball stud and remove the bearing from the lever. When installing the new bearing, attach the bearing to the lever and lubricate the ball socket with grease before securely seating the lever. For 1994 and 1995 models, install the bell housing and tighten the bolts to the correct torque specifications. Prior to installing the transmission, apply grease to the sleeve of the transmission front bearing retainer. Finally, complete the installation by following the reverse of the removal.

The removal process occurs by removing the transmission, leaving the engine in place to allow access to the clutch components; meanwhile, it is important to have an engine hoist or jack and a piece of wood under it before lowering down the motor to avoid crushing the oil pump pick up through the oil pan. The oil pan was next to the pickup; thus, care must be taken. Firstly, remove the release cylinder. In case of heavy-duty (cast iron case) transmissions, remove bellhousing-to-engine bolts and probably pry off the housing from alignment dowels. It's fine if you leave clutch fork and release bearing with housing. Consequently, it is recommended to use an alignment tool for supporting clutch disc when it is removed. Care should be taken while checking flywheel and pressure plate for indexing marks or scribed marks regarding their alignment. The pressure plate should be loosened gradually in a criss-cross pattern and its bolts can be removed after which pressure plate and then clutch disc are also withdrawn. One needs to inspect all clutch components including flywheel that has a pilot bearing for defects like twisted fingers of diaphragm spring as well as worn-out driven plate assembly (clutch dic). Rivets' heads on frictional lining above 1/16 inch are checked while rivets are not allowed to move freely; besides, any distortion or cracks are examined too before that disc is replaced. Also, one needs to check release bearing as well as machined surfaces and diaphragm spring fingers on pressure plate for wear or damage whereas if needed this part should be substituted. To ensure no oil or grease remains on them, clean flywheel and pressure plate surfaces using lacquer thinner or acetone just before their installation. For proper installation, position clutch disc and pressure plate against flywheel using an alignment tool while tightening each bolt of pressure plate-to-flywheel gradually in a criss-cross pattern . Finally these bolts need tightness after aligning the disc by using this tool. Before installing a clutch release bearing, it is necessary to lubricate it with high-temperature grease in contact areas of the release lever and release bearing as well as on transmission input shaft bearing retainer. Reinstallation is done of the transmission, release cylinder and all parts that were removed initially with all fasteners tightened to the recommended torque specifications.

The removal begins with disconnecting the negative cable from the battery and then removing the transmission. In case it is a heavy-duty type, the bellhousing should be taken off. The clutch release lever is detached from the ball stud on 1995 and earlier models and then this bearing is removed from the lever. On 1996 and later models, one removes the clutch release cylinder which leads to detachment of the release bearing from it. The inspection process involves holding the center of this bearing and rotating its outer part while applying pressure. If does not turn smoothly or is noisy, replace it with a new one. The bearing should be wiped using clean rag and inspected for damage, wear, cracks etc. The sealed-for-life nature of this part means it should not be immersed in solvent since doing so would ruin it. Installation involves lightly lubricating the release fork groove and inner groove of the bearing with high-temperature grease on 1995 and earlier models. After that, attach the release bearing to clutch lever carefully on these models as well before lubricating its ball socket with high-temperature grease till securely seated on ball stud. Similarly, ensure that you apply some amount of high-temperature grease only at face of release bearing where it contacts pressure plate diaphragm fingers since there is no need for it elsewhere too much greasing can cause slipping as well). For other models equipped with a heavy-duty type transmission, install bell housing tightening bolts to torque (as specified by manufacturer). Furthermore, before installation of the transmission itself put a light coat of grease onto its front bearing retainer here again we are referring to a small area (the size of approximately one credit card); yet an excessive application may result in transmission oil leaks through both input shaft or shifter boot openings if enough substance was used). The remaining procedure will involve putting back all components in their proper positions in reverse order one had previously followed I mean you have to do it the other way round starting from the last step to the first one.

The release bearing, release lever contact areas, and transmission input shaft bearing retainer should be lubricated with high-temperature grease before installing the clutch release bearing.

To attach the new bearing to the lever, lubricate the ball socket with grease before securely seating the lever onto the ball stud. Apply a light coat of grease to the face of the bearing where it contacts the pressure plate diaphragm fingers.

To remove the clutch components, the transmission needs to be removed, unless the engine is being taken out for a major overhaul. It is recommended to replace the clutch components whenever the engine or transmission is removed unless they are new or in near-perfect condition. The process involves disconnecting the clutch hydraulic fluid line, supporting the engine while removing the transmission, and inspecting the flywheel and pressure plate for indexing marks. The components need to be checked, and the clutch disc and release bearing should be replaced. The pressure plate-to-flywheel bolts should be tightened gradually in a crisscross pattern, and the clutch disc should be centered using the alignment tool. The release bearing, transmission, and all previously removed components should be installed, and all fasteners should be tightened.

After installation, all fasteners should be tightened to the recommended torque.

Before installing the new bearing, lightly lubricate the clutch release lever, the groove for the lever in the bearing, and the inner groove of the bearing with high-temperature grease.
