DSM cranks have a hardened layer and that's why the FSM says they are not serviceable. Its a big debate, many shops also don't recommend it.

Interesting, I was not aware of that. Thank you!

It's the nitride coating. Cheaper to find a fresh on than have it re-nitrided.

gotcha! Makes sense that they are case hardened, that would do a lot for wear resistance.

I called crankshaft supply today and to service my crank, it will cost $366 plus me shipping and shipping back.
That includes filling the thrust bearing on crank, cutting and polishing the mains, also the nitrate coating. The nitrate coating is $168 alone.
The only reason why i might send them the crank is that it was balanced, I don't know if it will still be balanced after they work on it.
And i am still looking for a good used 6-bolt crankshaft.
