Re: Pressing Pinion onto Banebot RS775
The RS775 shaft is definitely 5mm. The motor mounting holes are M4. The shaft has a negative tolerance as most of our motors have a shaft diameter of 4.95 mm.

We have successfully taken the FP pinion from the AndyMark Fisher Price transmissions and modified them for use on the RS775. We also have modified the AM Planetary motor plate to receive the RS775 for use in the AM Planetary. It works great.

We are match drilling and reaming every pinion to every shaft. We had to purchase a new reamer. I will find out which one we are using today and get back to you.

Paul
