Nissan 30502-69F10 Bearing Release

Remove release cylinder, transmission, boot, lever, bearing and hub. Inspect lever boot, wire retainer and bearing for damage. Pry release bearing from pressure plate. Remove pin and washer, pull out pivot pin, detach lever. Lubricate lever and ballstud, attach bearing to lever, insert lever through boot, slide bearing onto input shaft retainer, push lever onto ballstud. Apply light coat of grease to bearing and pressure plate, tighten bolts to torque.

To access the clutch components, the transmission must be removed and the engine supported. The release bearing must be pushed towards the engine and pried from the diaphragm spring. The flywheel and pressure plate should be inspected for indexing marks and wear. Replace the pilot bushing and release, and the lining on the clutch disc should have at least 1/32 inch of lining above the rivet heads. The machined surfaces and diaphragm spring fingers should be inspected for wear. Before installation, the flywheel and pressure plate should be cleaned and the clutch disc should be centered. The pressure plate-to-flywheel bolts should be tightened in a crisscross pattern and the release bearing should be lubricated. Finally, the transmission and components should be reinstalled and tightened to the proper torque specifications.

After that, remove the boot from the side of the transmission and disengage the release lever retainer from the ballstud. A screwdriver can be used to disengage the release lever retainer spring from the ballstud. For inspection, hold the outer portion of the bearing and rotate the center while applying pressure. If the bearing doesn't turn smoothly or if it's noisy, replace it with a new one. Wipe the bearing with a clean rag and inspect it for damage, wear and cracks. Don't immerse the bearing in solvent - it's sealed for life and to do so would ruin it. If the bearing needs to be replaced, remove it from the hub with a puller. The new bearing will have to be pressed onto the hub. For installation, lightly lubricate the clutch release lever where it contacts the release bearing hub and the ballstud. Attach the release bearing to the release lever. Make sure the bearing is properly engaged by the retainer clip. Lubricate the clutch release lever ballstud or pivot pin with high-temperature grease, insert the release lever through the boot, slide the release bearing onto the input shaft bearing retainer and push the lever onto the ballstud until the lever retainer pops onto the stud. Make sure that the release lever pivots freely and the release bearing slides freely on the input shaft bearing retainer. Apply a light coat of high-temperature grease to the face of the release bearing, where it contacts the pressure plate diaphragm fingers. The remainder of installation is the reverse of the removal procedure. Tighten all transmission-to-engine bolts to the torque. For all other models, the clutch release bearing and bearing hub are integral components of the clutch release cylinder. Replace the release cylinder as a single assembly.

Before installation, follow these steps: Clean the machined surfaces of the flywheel and pressure plate using brake system cleaner. Center the clutch disc using an alignment tool. Ensure the clutch disc lining has at least 1/32-inch (0.8 mm) of lining above the rivet heads. Lubricate the release bearing with high-temperature grease.

The clutch components should be replaced when the engine or transmission is removed, unless they are new or in near perfect condition. If the engine is being removed for a major overhaul, the clutch should be checked for wear and replaced if necessary.
