The crankshaft has a clutch pilot bearing that is a needle roller bearing that is pressed directly into the back piece of the crankshaft; it comes pre greased from the factory and does not need any additional grease being added. Its main duty is to bear part of front of the transmission input shaft, and ideally, it should be checked whenever the cardinal clutch parts are detached from the engine. Due to the hard-to-reach location, it is recommended to replace it if there are questions about its state. Where the engine has been spat out from the car, then some of these steps may not be followed. For the bearing, turn on the flashlight and look for excessive wear, scoring, dryness, roughness or any traces of damage; if such incidences are observed, then the bearing should be replaced. Removal can be done with a special puller, for example, a small slide-hammer puller which can be purchased in any auto parts store. For fitting or installation of bearing, remove a thin film of grease on the outer surface of the new bearing and then force it into the recess using the seal installer or a socket preferably with the bearing seal facing outwards. Last, replace the clutch components, shift, the transmission and all parts that have been separated, making sure that the screws are tightened to the right tension.
