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.

The assumption for working on a clutch system is that the engine will remain in place and access to clutch components will be through removal of the transmission. For cases where the engine or transmission has been removed, it is advisable that unless they are new or in nearly perfect condition, replacing the clutch components which are relatively low-cost is recommended because it could be cheaper than accessing them.To start off, the transmission is taken out of the vehicle supporting an engine. Engine hoists or support fixtures can assist, but if one uses a jack beneath an engine, he or she should put a piece of wood between jack and oil pan to distribute load. At that time, leave the clutch release bearing assembly attached to the transmission. As we remove the clutch disc,a clutch alignment tool is put through its hub.The flywheel and pressure plate should be carefully inspected for indexing marks or marked manually for alignment purposes. The pressure plate-to-flywheel bolts are loosened in a criss-cross pattern, and after relieving all spring pressure, remove the bolts, pressure plate, and clutch disc from there. Inspection includes checking for defects and imperfections on the flywheel; inspecting pilot bushing; examining lining of clutch disc for wear/damage; replacing release bearing; evaluating pressure plate for excessive wear, damage or distortion. Light glazing can be removed from pressure plate friction surface using sandpaper or emery cloth. The installation steps involve cleaning up flywheel and pressure plate surfaces with brake system cleaner; positioning clutch disc as well as pressure plate against flywheel; centering cluch disc with an alignmet tool ; tightening gradually pressure plat-to-fly wheel bolts in a crosswise manner; lubricating release bearing face with high temperature grease; finally installing clutch release bearing, transmission and all previously removed components while observing correct torque specifications and bleeding hydraulic system of clutch.

Disconnect hydraulic line from the clutch slave cylinder. Disconnecting the hydraulic line from clutch slave cylinder involves placing a special tool against the shoulder of the quick-connect fitting, pushing in on the quick connect and pulling out on the line. Take out transmission Remove two retaining bolts for clutch slave cylinder Slide off input shaft of transaxle Ensure that it rotates freely by rotating it and exerting pressure; if there is roughness or noise then replace it. It can be taken out from its clutch slave cylinder When removing the transmission, examine friction disc and pressure plate assembly Replace as needed Clean transmission input shaft with a light coat of high temperature grease Place new one into position, fasten with retention bolts until torqued Fill up reservoir with recommended fluid Connect hydraulic line to clutch slave cylinder Refill clutch fluid reservoir, using recommended fluid Bleeding clutch hydraulic system.

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.

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 bearing should be wiped with a clean rag and inspected for damage, wear, and cracks. It should not be immersed in solvent as it's sealed for life, and doing so would ruin it.

The pressure plate should be inspected for wear or damage on the machined surfaces and diaphragm spring fingers.

Prior to installing the transmission, apply grease to the sleeve of the transmission front bearing retainer.

On models equipped with a heavy-duty type transmission, the bellhousing is installed, and the bolts are tightened to the correct torque.

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.

The pressure plate-to-flywheel bolts should be tightened gradually in a criss-cross pattern.

It is recommended to replace the clutch components whenever the engine or transmission is removed, unless they are new or in near-perfect condition.
