Here's where you can buy the parts:

I would also clean eveything up REAL GOOD during your rebuild. Also check those center bearings to see if they have a lot of slop/wobble and need to be replaced. Once you do get everything put back together, make sure the drivetrain spins freely when the motor pinion IS NOT touching the center spur.

To set the mesh between the pinion and the spur, use any plastic parts bag and put it between the spur and the pinion. Press gently on the motor pinion until the bag is snuggly sandwiched between both gears and then tighten the motor mount screws. You should end up with only the slightest gap between the gears. The drivetrain should still spin...but you will notice that the magnets from the motor will provide some resistance. There should NOT be any "mechanical" drivetrain resistance resulting from the touching (incorrect meshing) of gears.

I will leave it to others here to make recommendations for pinion size as it varies with different setups and unfortunately, I have zero experience with Medusa motors.

Hope this helps.
