Main & Rod Bearing Markings

Tue Jun 08, 2010 4:03 pm

To those of you who have disassembled numbered Loboy C60 engines;
Did the Main & Rod Bearings from the factory come stamped with "STD" on the backs?
Did the replacement bearings that you have seen come stamped "STD", "010", "020", etc?
Also; any aluminum domed top replacement pistons that you have used, were they stamped "010", "020", etc on the top of them?
I am planing on dropping the oil pan and pulling a main and a rod bearing cap to check to see if the crank is Standard or not, without miking it. Planing on doing an "in tractor" thrift ring and bearing job.

Can not 100% confirm that all rod and main bearing shells are marked on the back. Most are. Pistons, I don't know.

You will have to remove the pistons from the engine. You will need to clean up and then measure everything before making any decissions.

I plastiguage the rod and main bearings during disassembly.
