I'm curious about a crank that came out of my '02 E440. It is the old style rod with a build date of 01 2000 on the crank web. The plug in the crank pin has a P/N EPC52 and 5/8 stamped on it. My other cranks don't have these numbers marked on the crank pin plug. I understand that the plug is removed to clean the pin journals when doing a bearing update. Since the original plug was removed and replaced can I assume that my crank has the Z400 bearing?

I wouldn't assume anything on a dale.

That's the truth!

I'm hoping that one of the crank/engine builders will recognize the plug. The engine it came out of had quite a few updates.

Ive used that number before and also use green locktite on most of them . The stock plugs are thinner as well. But of course its a good sign to have an aftermarket plug but that might just mean the crank was cleaned. If the rod was actually remove there might be press plate scratch marks on the sides of the large journal.
