Crank Pulley Slipping

[david-b]

When I finished my build, I didn't thread lock the crank bolt holding on the UDP. The bolt ended up falling out while driving and the pulley slipped on the crank. You can clearly see the scratches and the shavings.

I got everything running fine at the moment, but the crank pulley is slipping on the crank. The bolt is on there are much as I could get it on. But the pulley is slipping and knocking around.

So my questions is, is the UDP (which is aluminum) shot, or do you think the crank itself is damaged? And if so... now what?

its more likely that your udp is shot. You can test that out by putting your stock crank pulley back on and checking to see how things run, if thats the case you can stay with the stock or buy another udp

I actually don't have the stocker, and just threw away my last UDP (broken lips) so have nothing to test with.

Is it possible to damage the crank or is that impossible from that?
