Filawinder guide motor jamming.

Wondering if any one else is having the same issues as me or if I just managed to tear my motor apart. But the motor controlling the guide arm cant withstand much pressure when forcing the wire over while winding it before jumping severely back and forth until the filament finally decides to move over. It doesn't take much pressure to cause this and am thinking i broke my motor some where down the line cause if i remember correctly while assembling it I had the nob turned all the way over like a retard and pushed the left button and caused it to come down onto my hand with much pressure.  Moving it around and about i assume i broke the motor loosing much of its torque. And looking at how much pressure it can push on the filament now is no where comparable to how it was. If any one can point me in the right direction of a new motor to test that will be a plug and run preferably not from china would be amazing.
