Re: Drivetrain issues

There are a few things that pop out at me from your post. If you keep popping chains and shearing keys it sounds like something is out of alignment. The issues I can think of that could cause this is sprocket misalignment, gearbox misalignment, Not securely mounting the gearbox (ie. no top support plate) or even perhaps something in binding in your gearbox.

A picture of your drive train would go a long way in helping you diagnosis the problem.

I have run 4 CIM drivetrains for a number of years with none of the problems that you are experiencing and it is obviously something other than the number of motors in your drive.
