Okay, so I'm swapping in an SM465 in place of my old POS 700r. As I'm doing it I have a pretty good idea of what to do, but I get to installing the pilot bearing, and there are two in the install kit, the actual bearing style one and the sleeve style one. I was a little curious as to which one to use, so I posted on Pirate and waited a while. Nothing. So I go back to work and install the sleeve one, since that is the only kind that I've seen installed and I figured with fewer moving parts (none) it would probably last longer. So I use the grease that came with the kit (looked like white lithium grease) to grease it up pretty good (kinda like this article indicates: http://coloradok5.com/auto2manual.shtml). However, after I bolt up the rest of the clutch assembly and the bellhousing, and go back to update my post on Pirate and some guy has said that it is fine to use the sleeve style one, but to NOT grease it up. Uh-oh. He said that it would heat up and would melt and end up binding the engine output dealy (don't know what it is called) to the pilot bearing shaft. My question is has anybody ever heard of this happening before. If so please tell me now so I can fix it before something goes horribley wrong. Thanks.
