Crank hub

What is the part number and source for the crankshaft hub which is keyed onto the front of the crankshaft. (1994 E420) mine may be stripped.

Hub is NLA, if damaged beyond repair you'll need to source a new one.

How is this "stripped"? There's no threads. It's a press fit onto the crank snout. A puller is needed to remove, installation requires heating per FSM spec so it slides into place.

This applies to M119 engines with the 2-piece hub/balancer through, IIRC, early 1995 model year production. Late style 1-piece is a slip-fit, completely different.

Some time ago, while torquing the five or six (I forget how many) bolts for the harmonic balancer and pulley, I was unable to achieve the listed torque. They kept turning. I thought the hub was tapped for these bolts? Perhaps I need a harmonic balancer?
 
Why not just repair the threads? There are a lot of repair kits on the market for this.

This will be a good opportunity to also replace the front crankshaft seal.

AH! Yes, if those threads are stripped, repair them. That will be easier than replacing the entire hub. Replace the seal if it's not recent or new (cheap insurance).

What torque spec were you using, btw, and what torque wrench?

35nm torque using a Harbor Freight torque wrench.
