What to do with crank

[ed1380]

I got a crank sitting here from a rebuild I just did. It's going to need to be recut. I'm wondering if there's people out there that buy bad crank to cut them and resell them. Just looking to get rid of it, and dont want to send it to the scrap yard

There are people out there, alot of vendors on here take them as core, and send you a different crank. They repair yours and then they sell that to whoever. I think thats unprofessional, as sometimes I would send in a nice clean crankshaft that needed minor work. THey would send me a somewhat rusty .25mm cut crank. Pissed me off but o well.

I bought a different one, so didnt need to return a core

do you know any shops that do that?

The original nitride hardening treatment extends deep enough into the surface of the journals that a minor cut doesn't usually remove it all, -but the hardening rapidly weakens the farther into the surface you cut. Running a cut crank certainly isn't ideal but there are some who have done it without issue. I won't recommend it.

The good news is that some nitride hardening processes can be repeated on the same part in order to restore or even further strengthen the treated surfaces.

The bad news is it's almost impossible to find someone willing to perform this process for you, and if you do it won't be worth it when you can just buy a good uncut used crank for $150.

Looks like you got a really big paperweight or a really small boat anchor on your hands.

My crank was cut, and when I pulled it out it had cracks everywhere.

If it needs to be cut, I throw it in the trash.
