Factory new air compressor!!

[JMBT]

Hello all, I have a 2012 CM2250, 810k, 500hp, in a Volvo. I just finished re-assembly from tearing down for a leaking flywheel gasket. Let me just say it was a huge job to do by myself....huge! If it leaks again I might just head for Mr Haggs!

Anyway, I bought a brand new Cummins air compressor that took forever to get straight from the assembly line in Memphis. I am in the process of priming and painting it. I think the old compressor caused the flywheel gasket to leak by way of putting compressed air into the crankcase. It was original with 810k and when I got it off I could easily spin it over by hand.

So my question is, on the CM2250 is there any timing that is done for the compressor when it is installed? There are no timing marks at all on it, and it is very difficult to turn over by hand. Also QuickServe says nothing of timing in the install instructions, but I remember something in one of Rawze’s videos about timing a new compressor on the 871 engine.

Thanks
