Fixing gearbox assembly inconsistancies

[StealthMentor]

We sent two back this year one for a gear that the bore was broached crooked, and the other was not the right width causing a lot of slop. The ones we got as replacement where fine but the included kit to mount the gear to the CIM with the two washers below the gear (as per instructions) the washers actually hit the next gear and make it so it wont turn. The washers are too big in diameter. We removed one washer and it now works fine. Andymark needs to step up their quality control!!
