Scratch that...I misread your post. The above is a bushing, which I personally would prefer over a roller bearing.

The bushing has no moving parts. It is also much more tolerant to slight misalignments. A bushing is also soft and will not bugger up your input shaft in case of failure. Don't over think this. Get a 2 dollar bushing, put a dab of high temp grease on it and forget about it. That's just my opinion. Originally Posted by Takid455

When I got my TKO, they insisted that the "needle bearing" style pilot bearing was an absolute must.

Who is "they?" I would love to know the reasoning behind their insistance. Originally Posted by Tom 72RS/SS

Go with the bushing! I actually ruined a needle bearing trying to install my richmond, the bushing is more forgiving.

If you insist on roller pilot bearing try:
BCA 202-FF .5906 Bore x 1.378 O.D. Timkin can reference this part number as well. Cost - $8.83

It was Classic Chevy 5 Speed that claims since the TKO is more precise than the Muncies and Saginaws, a needle bearing style would perform better.
Personally, I don't know either way but one came in the kit so I put it in and all works as it should.

Bumping this one to the top...
Is there any reason why I should be searching for a roller pilot bearing vs. the bushing type for use with a TKO600?
Also, can anyone verify that the 400 SB takes the same pilot bearing as all other small blocks? I had a dumb parts guy that's attempting to overcomplicate the issue....Jeff K.

If you have an aftermarket crank, chances are a bearing may be too loose. It needs to be a slight pressure fit. I tried several bearings and all were too loose, so I went with the bushing. I tapped it a few times around the circumference with a punch to ensure it was tight. I'm running a TKO600.

If you install a TKO, it is a must that you use a needle roller bearing and not a bushing. Tremec requires it as does CC5S and Keisler Engineering. It will void the warranty if you do not use one.
CC5S is correct, the tolerances on the TKO are much tighter than a muncie or A833 or T10. Therefore a roller bearing must be used. If you grab the input shaft of a muncie, A833 or T10, you can literally move it in, out, up, down etc... because of the "play" in it. You cannot do that with a TKO. It will not move. That is the reason for going with a bearing over a bushing. The bushing will give, the bearing will not. That is also why you MUST perform the bell housing alignment check (runout) when installing a TKO, to ensure the input goes into the crank as straight as possible.
For the record, the Pontiac and Olds motors use a ball bearing style bearing which is fine for use with a TKO. In fact, that is what we supply in our kits with those motors.
