It can help ease side loads on your tranny's front bearing and seal and maybe make them last longer.
It's in a better position, leverage-wise, to resist any bending moment applied to the tranny's input shaft.
I just checked your invoice dated 6-15-2004 and you should have gotten a pilot bearing with all of the parts. It was included on the clutch & flywheel bolts. I have plenty of them and can ship one to you if you can't find it.
YOU NEED TO INSTALL THIS BEARING. When you push your clutch in this bearing centers the clutch disc and allows the pressure plate to spin free. Think about it, without this bearing all of these forces have to be generated by the bearing in the trans input shaft which is well behind the disc. Running it this way will destroy the input shaft as well as the bearing .
Don't run it without the pilot bearing. It allows the clutch to engage off center, placing a load on the crankshaft and trans when the crank rotates. I did this for 16,000 miles on a Pontiac 350 and actually broke the crank.
There sure are some interesting issue on this site from time to time. Forgotten pilot bearing, that's a new one to me. Easy fix, though. Every auto parts store in this country should have a 5.0 pilot bearing on the shelf for under $20.00.
HEH! I was over Pats house helping him with Charlies car as we were mating the trans to the block Pat said that we must remember to put this pilot bearing in and that got me thinking about mine.. I didnt remember doing this, and just wanted to make sure.
Trans coming out again before the next race.. Thanks guys.
