Re: Pilot shaft bushing wearing fast and often!!
Oilite type bearings in an auto engine? They worked reasonably well in low rpm computer gear where the side load wasn't very high and the rpm range was low. Excess oil was never good news.

Re: Pilot shaft bushing wearing fast and often!!
That's what was used in pilot bushings for as long as I can remember. Low
duty cycle, heat, inaccessibility, and undesirability of excess lubricant were probably the main design factors. Maybe Volkswagen Bug was the first large scale production car to use a roller bearing type. First one I saw anyway.

Re: Pilot shaft bushing wearing fast and often!!
They call it a 'bushing oil wick' in my book. This wick gets stuffed
into the end of the crank, then the 'bronze' bushing gets pressed in. Once the tranny nose is inserted there isn't much room for oil to pass. It isn't like you fill the end of the crank with oil or something....
