Re: Reducing Friction in Shooter

Sounds like something got assembled incorrectly and/or something is damaged. I would suggest taking the gearbox apart and checking everything very carefully. Clean off grease etc. to get a good look at everything and see what's wearing or binding.

I would also make 110% sure that you're actually getting into neutral and disengaging completely.

Things to check:
1) All bearings rolling smoothly
2) Abnormal wear on gears (a little black discoloration is okay)
3) Any wear on the sides of gears (very bad)
4) Wave-washers installed in the proper locations
5) Gearbox housing distortion
6) Any side-loading on the output shaft
7) Any slight misalignment in how the gearbox is mouted

Pics would go a long way, especially of disassembled components.
