The clutch pilot bearing is a needle roller type bearing pressed into the rear of the crankshaft, greased at the factory and requiring no additional lubrication, primarily supporting the front of the transmission input shaft. It should be inspected whenever the clutch components are removed from the engine, and if there are any doubts about its condition due to inaccessibility, it is advisable to replace it. To begin, remove the transmission and the clutch components. Using a flashlight, inspect the bearing for excessive wear, scoring, dryness, roughness, or any obvious damage, and replace it if any issues are found. Removal can be done with a special puller or an alternative method involving a solid steel bar, wood dowel, or a bolt through a socket. Ensure the bar fits snugly into the bearing, then pack the bearing and the area behind it with heavy grease to eliminate air. Insert the bar into the bearing bore and strike it sharply with a hammer to force the grease behind the bearing, pushing it out. Alternatively, pack the recess behind the bearing with heavy grease and use a steel rod to hydraulically force it out. After removing the bearing, clean all grease from the crankshaft recess. For installation, lightly lubricate the outside surface of the new bearing with grease and drive it into the recess with a seal installer or socket, ensuring the bearing seal faces out. Finally, reinstall the clutch components, transmission, and all previously removed components, tightening all fasteners to the recommended torque.
