Subject: Re: What's a Pilot Bearing? ('88)
Just finished replacing clutch, T/O bearing, pilot bearing while in there
doing trans repair. Tim gave some sorely needed advice and encouragement.
The pilot bearing from VW was only $6.50 CDN !! - that was a surprise. The
clutch disk was less than 50% worn measuring against replacement lining
depth to top of rivet heads. Km was at 240,000. So predicted possible
mileage could have been as high as 500,000 km - but T/O bearing was dry and
noisy, pilot bearing still ok so replacement would have happened before
lining worn out. As for use, I tow a sailboat occasionally, canoe on top
often and bikes on back and sometimes all together! but clutch life probably
more depends on how much slip is used on take up.
So first clutch replacement at 205,000 km sounds reasonable but 50 Kkm is
definitely not. Mainshaft damage may have been due to failed pilot bearing -
cause who knows? (Pilot bearing is small needle bearing pressed into center
of end of crankshaft that carries tip of mainshaft - it is lubed with grease
on assembly and only turns when clutch is not fully engaged)
