rod bearings

caseman68 · Aug 16, 2020

Hi ,I need to replace my rod bearings on my HD6G after I had diesel leak into my oil pan.oil pressure has dropped to 5-10 psi and its knocking.
Does anybody know what the tolerance should be around these bearings? I plan to just plastiguage them.

If it's knocking it more than likely has ran a bearing,do not run it any more as that will cause more damage to the crank might even throw the rod,get the oil drained and the pan off to see what's wrong.

The rod bearings are .12475''-.12525'',bearing shells that measure less than .123'' at center should be discarded

Thx Hector , engine is all original would it be a good call to order standard rod bearing instead of .10 or .20 over?
