4104 greasing the pilot bearing

[dtcerrato]

Buswarrior what you're saying is true but during our recent in frame rebuild the crankshaft main thrust bearing was the most worn of all the bearing set do to the fact that I too have been doing the foot on the clutch thing for lots of years. Not detrimental but there is a trade off.

Yea a clutch in GM bus engine when the thrust bearing wears it transfers to the oil pump on the 8v71and makes a mess of the oil pump the play has to go some where and the oil pump is the last in that line
IMO both GM and early MCI had a poor clutch system using the slotted fly wheel with center plate that just dangles in the slots,a mushroom style clutch beats those by far
