We are trying to set up a Falcon 500 motor with a tough box micro. We have 14 tooth spline bore steal gears that just don’t want to go on and when we do get them on they go down about a cm then will not go on or off. Any suggestions on how to place these gears?
I would contact Vex and try to get replacement pinions, but failing that you can heat the gear with a heat gun to get it in easier. You can also dip the shaft in ice (dry before using and don’t dip the motor) or dry ice.
