1. my motor keeps loosing up. I've tightened the screws a few times and it keeps happening from time to time.
2. When I set the spur gear and run it, it slides back a bit. enough that it doesn't line up with the pinion.
How can I resolve these issues?
I play til something breaks
Maybe you can tighen the screws more than you think. Some blue loctite might help.
Nobody is born with experience
1.The thread may have worn and that why it keeps coming loose so you can get a new motor mount,or screw,or put threadlock
on it and let it set for 12hours
2.the spur gear can move back and fore so try and get it lined up so the most part of the pinion is always on the spur hope that helps dude...peace
Famous last words...watch this!!!!
