The clutch pilot bearing is an assembly of needle rollers inserted and retained in the rear of the crankshaft, supplied with grease at the time of manufacturing but will not need any further re-greasing, its main function is essentially to support the forward part of the transmission input shaft. It should be inspected whenever the clutch components are removed from the engine and where there is insecurity resulting from the position that the bearing occupies, it should be replaced with a new one. If the car's engine has been pulled out, even some of the standard protocols are not followed. Start with the removal of the transmission, finally followed by clutch parts. Lubricate the bearing and visually check the bearing for signs of wear, scoring, the absence of lubricant, dryness or damage, If any of these signs are present then the bearing must be replaced and the use of a torch light may be required. Removal can be done with a special puller and slide hammer; to install a new bearing, lightly coat the outside with lithium-based grease and drive it into the recess with a soft-face hammer, with the seal facing outwards. Last but not least, everything installed in reverse order, including clutch components, shift assembly, shift cables/hoses and all other parts removed during the process, make certain to tighten all fasteners evenly.
