zulu Posted November 10, 2008 Report Share Posted November 10, 2008 Could anyone please help - whilst doing an engine rebuild on my 348 after splitting the crankcases i have two brass shims the exact size as the crank bearings - i don`t know if they fit on the inside of the cases up against the crank or outside near the seals?

feetupfun Posted November 11, 2008 Report Share Posted November 11, 2008 The shims fit between the seal housings and the main bearings ie outside the bearings. If you have split the cases (new gasket), fitted a new conrod kit or even new main bearings, you will need to determine what thickness shims are needed. A common mistake made when assembling that motor is to bend the crankshaft by squeezing(bending) the crank when fitting the seal housings.
