Reply to "Pilot Bearing"

bosswrenchMember

I'm not a big fan of needle-bearing pilots. That area is hot, spinning at high rpms, under fairly high side-load in all gears as the ZF has no 1-to-1 ratios, is covered with abrasive dust from clutch disc wear and cannot be well lubricated nor sealed. Many are light-duty alternator bearings that were resized to fit.I favor the stock bronze bushing; I've personally seen transmission input shaft noses destroyed by seized needle bearings, and you REALLY don't want to price a replacement ZF input shaft.... Note also that some Taiwan-special "bronze" bushings are MAGNETIC from the iron filings they add to cheapen an already cheap part. These abortions will also wear the input shaft noses rapidly, being much harder than real bronze. Take your magnet with you when shopping for pilot bushings.
