JBU motor pinion gear spinning on shaft.

Of course it happens the day before a skirmish, I've made a video explaining my problem.

How would I go about re attaching it?

Re: JBU motor pinion gear spinning on shaft.

Take the motor to a shop and get them to pop a new pinion on the motor - if it's spinning freely like that then my guess would be the pinion has cracked, or the motor shaft is worn down - in which case you need a new motor.

I've had a good look at it, and it doesn't seem to be either, so I am going to tap a hole in the pinion gear and put a grub screw into it.
