First, read this carefully. I'm not going to re-use the bearings. Never planned on it. I am just looking for input on condition and wear patterns.

This past weekend I was able to split the case on a 2.2T engine I am rebuilding for my 914. So far the tear down has been great, nothing broken, no chunks of metal or debris, everything came apart without much fuss, and the case has time-serts.

Case is apart now, most of the bearings looks really good, a few have some wear. I've had a few engines apart but not many, and those were special circumstances so I don't have a lot of personal experience reading wear on bearings.

One case half

From one end to the other, close up's on each of them

This one seems to have much more wear than all of the others for the crank.

The dark spot here is oil.

Wear on the far edge of this one.

For the intermediate shaft bearings:

More wear here too.

Any thoughts or input from you guys and gals? The engine was a core, unknown history. Buying it was a roll of the dice.

That is about what my 914-6 engine looked like when I disassembled it. I guess the intermediate shaft bearing at the chain and gear end is subjected to a higher load than the pump end. Mine was worn to the copper as yours is and as evenly as yours too.
