Beware - transmission output shaft is not 5/8"!

I can't believe that FIRST is so generous as to provide such a great gearbox, and some of you still complain and find every little thing wrong with it. If you don't like it, make your own. But let's not complain when we are getting magnificent items in the kit that teams just a few years ago could only wish for.

Back in the day, we never had beautifully machined pieces included in the kit of parts. Hexed broached gears. Cast housings. We didn't even have CIM motors.

Be thankful for what you have, not frustrated with it because it doesn't exactly suit your needs.

I agree 1000%!

A dremel tool with a sanding cylinder and 10 minutes will make a standard 21 tooth 5/8" bore sprocket fit. A 9th grade girl team member did ours last night.

We decided to turn down the shaft, as that then gives us the ability to change sprockets easily, should we want a different gear ratio.
