Trick Pilot Bearings?

[RTillery]

What kind of aftermarket tricks are being done to the pilot bearings to improve shifting, longevity, quality of life, in the trucks that are laying down above stock horsepower.



I think the stock one is a roller bearing, and I see SBC sells a Kevlar unit. Seems I have heard of an oversized roller that requires machining out the flyweel. How about some feedback on what is out there, how is it working and what is a longterm high mileage soution? TIA

R,



The stock pilot bearing is a needle bearing. I just bought a Con O from SBC and asked about the kevlar bushing and Peter recommended a new roller bearing that they are using. It does have a much larger OD than the stock needle bearing. Your flywheel will have to be machined for the OD but they will need to leave a "lip" on the engine side because the roller bearing is thinner than the needle bearing. Mines working great, only about 1K miles on it though. I think the main thing with the roller bearing is that it is alot less susceptible to damage when installing the transmission.

The roller bearing and a fresh cut on the flywheel changed my OFE from undrivable to just like stock. The difference was that big. PDR had them in stock when I was up there last and can tell you what the machine shop will need to do for the install.

Quad 4X4 has a good one also, and besides the damage when installing the transmission not happening, they are sealed to keep the water out. Honda cars have been using them forever.
