I so, do you happen to have a part # ?

I put ARP rod bolts in my stock rods, 2 of them moved enough the machine shop said they needed to be opened up and oversized rod bearings used. I got all the stuff back from the shop and started assembly yesterday.

When I installed the first rod and piston, when I torqued it down, the engine wouldn't spin over. So, I took it back out. I remember the shop telling me I'd need .001" oversized bearings. Well the ones they sent with me are .002" oversized.

Sealed Power Part # 8-255A 10X2

I can't find a part # for a .001" oversized except for a C8-7100CH 1X on O'Reilly's website.

Can anyone point me in the right direction. I'm sure the bearings I have are my problem.

TIA

 

I ordered .001" oversized rod bearings (.001 more oil clearance) from TSP for $9 each plus UPS shipping.

Clevite CB-663 HXN

Hope this helps.

 

The bearing you need is a .002" oversized OD bearing. When you resize cracked cap rods, you oversize them .002" to get the bore round again. Clevite has them, PN 1776-P.

 

Well, I have Sealed Power brand .002" oversized now. I think what must have happened is the shop must have honed the rods .001" instead of 002"

I'm sure now that I've torqued that one, the bearing will be no good. I'll take it all back to the shop tomorrow and let them check it out. Maybe they'll just need to hone the rods another .001".

Thanks

 

Hello , just curious as to what the outcome is with You're bearings/rods ? Sealed Power also makes LS based gen3/4 rod bearings in standard ID .002" OD oversized . .001" oversized ID .002" oversized OD , and all the normal overID sizes that also are .002" overOD sized . Good luck . BTW the Clevitte 1776 1's are aluminum if that makes any difference 2 You're build ,,,,,,,,they're the 1's I'm gonna be running .
