[motojeff16]

I had the crank polished and having a couple questions about the bearings

the book says for limits
mains 1-4 2.9517 to 2.9520
mains 5 2.9515 to 2.9518
oil gap 1-4 .0018 to .0033
oil gap 5 .0022 to .0037

rods 2.399 to 2.401
oil gap .0018 to .0039

mine read out at now

mains 1-5 2.949 all round

rods 2.397 all round
what size of bearings would I use std. ??? any help would be appreciated
the engine 6.5 TD F Block 1998

Looks to me like you need to turn it down .010 or get a new crank. All your numbers are out of spec for standard size bearings. I don't think you can get bearings for a crank that is .001-.002 under.

I am guessing that is the gm manual. What did the machine shop say the turned it? Like .005 on the rods and .010 on the mains.

they said that they just polished it and it was still standard bearings

Then use std bearings

I found that there is .026 bearings that will bring everything into good measurements when done

I hope the maged the crap out of the mains. 98s are super crack prone.

It says 2 year warranty on complete engines and 1 year on long blocks. They don't list prices without logging in, but I don't see any way to log in.
