Interested also... I've had the motors apart, not much to them. Got one that grinds loudly and can't figure it out. Going to send that one back.
I suspect it's coil rod (Acme thread) or similar, and like you, assume it's pretty straight forward. Take pictures... because I can't offer any thing about what to expect.
Agree; the manual on these things is brutal, even for those that spend their life wrenching/swinging hammers, etc. Had to do it once; it just laughed at the Hilti impacts. Never tried a pneumatic either.
Nice post.. glad the weekend worked out for you.
