  Q: How to inspect and replace the clutch pilot bearing on Mercury Capri?

  A: The clutch pilot bearing is an LZ needle roller bearing retained on the end of the crankshaft by an O-ring, which cannot be replaced; if there is evidence of leakage or if the bearing is dry, then it has to be replaced with its O-ring towards the trans. Lubricated at the factory, it does not require further lubrication and mainly supplies the front of the transmission input shaft. Periodically, parts of the clutch are replaced, and whenever this is done, the clutch should be inspected; in case there is suspicion of its bad state, it should be replaced. Before disassembly of the transmission and clutch, there should be signs of wear, scoring, lack of grease or damage; in all these cases the clutch bearing must be changed. It can be pulled out by using the special puller and slide hammer or with the help of solid steel bar of appropriate size, which must be slightly less than the diameter of the bearing in order to fit it firmly. The bearing and the area behind it should be filled with that grease so as to expel air and a bar can then be hit with a hammer to impute pressure behind the bearing, which will in turn expel the grease. Post removal, degage the crankshaft recess and cover the new bearing lightly in lithium based grease before bounding it into the recess with a soft-faced hammer while ensuring that the seal forms the outer side. Last of all, replace the clutch components, the transmission, and all the parts which had been removed, make sure to tight all bolts and screws properly.
