I'll have some bolts for the motor.
With the tcase, you need to put loctite on the bolts when you put them in and dont tighten them down. Just make them pretty much a little more than finger tight. The tolerances are just a little off on the bearing retainers on them and it makes them really tight when you tighten the tcase down all the way. Mine has been fine with the bolts basically little more than finger tight and loctite. The case halves almost snap together anyway, so the bolts are almost un needed.
