Rod Bushings for KB Pistons

1980_Cj7

Found the following at Diamond Racing: Part# 02-5038 OD - 1.010 ID - .927 Length - 1.110 Will they work? What I'm seeing on KB's web site is that you need 1.0006 OD, .9272 ID, and they don't mention length. I know the ID can be honed out to work with the pins, but how bout the ID and length, will they work? I'm trying to round up the parts we need. The other thing I'm thinking is I could just let the machine shop get the bushings. Still waiting to hear from them on what size bearings we need to order.

A quick call to Diamond will tell you the story. Generally any rod "bushing" for a .927 pin would be a floating bushing and set to industry stds.

You can hone out the rod a few thousandths for a press fit if you need too.

I did email Diamond. I sent them the specs on the KB pistons that included a note concerning bushing the rods and the dimensions. Diamond replied saying they have a bushing that is "close to what I need" and gave me the part no. and specs above. I guess the main thing I was unsure of was the length.

Mine were a bit long but not a problem. I think we opened up the rod about .007 to get the right press fit. Don't remember what the actual bushing dimensions were.

Anybody got a rod handy that they could measure the thickness of??? The small end where the bushing would go. (I personally know one guy who has about a jillion laying around his garage if he's listening, ha, ha.)

Thanks Matt. I was thinking about Fuzz to tell you the truth, not you, but I'll bet you have even more than Fuzz now that I think about it. (Now Fuzz will go and get all jealous and run out and try to find more 401 parts, ha, ha.)

Well according to that, those ones Diamond has should work just fine I guess. Guess I'll get 'em ordered a while.
