FWIW, I don't like rolling-element pilot bearings in high performance engines
for the identical reason I don't use high-iron bushings there: bearings scar
up the transmission input shaft when (not if!) they go dry. The location in
the back end of a crankshaft is possibly the worst place for a bearing in the
whole car- its hot, there's abrasive dust is everywhere from clutch wear, no
possibility of periodic lubrication- all the things a bearing DOESN'T want!
If you absolutely must use one for some arcane reason, be sure the bearing is
a truely sealed type; most are simply dust-shielded, not sealed and these are
the ones that fail first. And some are adapted from alternators! For those
users, I have developed a possible repair system for torn-up clutch input
shafts- but you gotta remove it from your ZF first! Good luck all- J Deryke
