5.9 Magnum rod bearing question?

5.9 Magnum rod bearing question? - 01/01/09 09:21 PM

I pulled a rod bearing to inspect from a 1999 RT motor. The marking says "12 98 D, DA 49"

So how do I read this to determine what the bearing size is? Would Clevite 77's from Mancini be adequate replacement? I don't like the look of the bearing and thirty some dollars for a set are cheap insurance.

mike the rod journal to find out the size...

12 98...date of manufacture for the bearing...which fits a 99 engine..

u should see on the other end of the bearing...

std..for standard ...or .010..of undersize journal

The lower portion of the shell is marked "12 98 C" No other markings. I don't have a mic large enough to measure the journal. I have never seen a bearing without a size on it.

They don't always say "std", I would push the rod up in the cylinder and mic it with something to verify std which it most likely is with that date.
