So I posted this in my build thread, but thought I would put something here to help get some input. I started seeing movement in the motor, not in the axle but rather the motor housing itself, up and down. Figured I didn't tighten it down well enough, or the bolts and lock ring became loose, so I tightened everything down. Still movement. Took the lock ring and mounting bracket off and this is what I found.


Basically the movement was from the motor torque, I am guessing, and created some nasty grooves on my frame. My concern is that this is a steel frame and I do not want rust to form, plus now no matter how hard I crank, the teeth on the bracket wont grab well in those grooves. I have seen the use of Epoxy Putty and heard about hose clamps to stop movement, but wondering if I should grind this down to get the teeth of the bracket to grab again? What should I do to rustproof this area now? I am in Seattle, so avoiding rain is a lost cause.
