933F Engine Bearings Undersize

All

I have a 933f 25a that has turned a bigend bearing the rest of the journals are average as well so was hoping to grind crank and run new bearings.
However working with the local cat dealer here in OZ the rear main bearing is dis-continued and the others are available but pretty rare I have asked a few others here but they were doubtful.
This machine is the Aus built one equivalant to the 42a its electric start non turbocharged has fwd reverse lever.

Part Numbers Below

Rear Main 1x 7m9284
Mains 4x 7m9285
Big End 4x 9h4620

According to the cat guys there is no updates to these numbers should be 0.030 undersize

Any Help appreciated

That's for the D311H. Rod bearings can also be found under the Clevite CB695AL30 number. I don't see an interchange for the mains.

I see one set 7M9656 0.030 under main bearings here...
