Bronze Pilot Bushing I was going to put the Bronze Pilot Bushing in my Car when I install the T56, is that a good one to go with, or is the factory Roller Pilot Bearing a better option?

I went with the bronze bushing on my clutch install about 5000 miles ago. I bought a factory roller bearing to use until I took the stock one out and changed my mind. The factory roller bearing sounds like a good idea, but the lubrication dries out and you end up with garbage. You'll see when you take yours out. If you still want to go the factory route, I have an brand new GM roller pilot bearing I'll send you for $12 shipped. p/n 14061685. I have no use for it.

Both have their pros and cons . The bronze bushing will wear and not damage the pilot tip on the input shaft . The roller bearing usually last longer and provides a better alignment of the input shaft but will tear up the tip of the input if the bearing fails .

Most of the time , a bad pilot bearing has very little symptoms . Some are jumping out of 4th gear when letting off the gas in that gear , front seal leaking on transmission , rubbing sound from input shaft rubbing the inside of the slave cylinder and a squeel/chirp sound in between shifts .

Check it the next time you change out the clutch. Really, this is a low priority item on these cars and nothing you should worry to much about. They were using bronze pilot bushings on cars since the beginining of time. Fred Flintstone probably had one on his car. It's just a little softer than the input shaft and is naturally lubricated due to the materials used. Put it together and forget about it. These cars have enough real problems to worry about.

Dido, do the bushing, the bearings will eventually dry out and then in time cause friction which will slow your input shaft speed from your output shaft speed which will lead to grinding gears when shifting. The bushing is self lubricating and last forever pretty much, but make sure after you put it in your resize it with something that is the same diameter as the input shaft that way when you go to put the trans back in it goes in smoothly, good luck.

My stock pilot bushing lasted 179,000 miles before it went bad. It was making scratchy noises when I accelerated from a dead stop. A couple weeks after I noticed the noise, some of the synchros in the tranny started getting noisy. I'm not afraid to use the roller for stock apps. I'd go with the bushing if putting some power to it is your goal.

Well this bushing doesnt work. I think its a swap bushing for use with older style trannys. The tranny will not mate with the bellhousing. So unless anyone has a part number for a bushing i am going to get an oem bearing tmro. This bushing would probably work with a ctsv or corvette that uses the bigger style pilot bearing
