Well I got my Banebots parts finally and here is an update on mating the P60 to an FP motor.

First off, be sure to check your pinions. Different ratios of gearboxes use different sized pinions and this is not very clear on the BB website.

Step 1 is to get the origional pinion gear off of the FP motor. I have no experience with the gear pulling technique mentioned above. We found that the original FP pinion is too tight to punch out with a pin punch and hammer. We ended up clamping the gear in a vise and cutting it with a hacksaw. This loosens it's grip on the shaft allowing you to pin punch it out. Be sure to cover all of the holes in the FP motor with tape! If you do not the magnets will pull metal filings into the motor and destroy it.

Step 2 is to cut the FP shaft to length. I cut 0.25" off of the shaft using a dremel. I also chamfered the tip to make it easier to set the new pinion on the shaft.

Step 3 is to reduce the diameter of the FP shaft slightly. The splines on the FP shaft make it slightly over diameter. I (gently) clamped the motor down and ran it while using a jewlers file on the splines. once again, be careful not to get metal filings in your motor.

Step 4 is to press the new pinion onto the shaft. A small arbor press is best and you MUST support the FP motor underneath where the shaft protrudes out of the motor bode. The motor should be resting on the tip of the shaft where it protrudes out the back and the gear shoudl be pressed on the top. be sure to keep everything square.

When you open up the gearbox to attach the motor to the back plate you will have to add lubricant to the gears.

Good luck everyone!
