Like the title mentions... I've got a pinion that's stuck on the shaft of my motor. I managed to move it slightly, but unfortuntely to the wrong side
![]() I was thinking of taking the motor to the workshop at school, putting the pinion in the bench vice and tapping on the shaft to get it out. I was wondering if you have other ideas to do it? ![]() |

The motor is off the car yeah, it makes access a lot easier.

If possible apply some heat to the pinion first from say a lighter or similar then use two medium flat blade screwdrives opposite each other under the pinion and try to lever it of using the motor case as a support. Long nose pliers or wire cutters may also fit under the pinion.

I mean the pinion on the shaft, not the motor.

use a pair of side cutters under the pinnon and use the leaverge to slide it off.

![]() ![]() Whereas the taps did work it seems the leverage of the pliers doesn't. I'm calling it a day now, I've disassembled a full buggy and sorted the parts, and I completely cleaned and rebuilt the gearbox of another one. Just the pinion issue to solve - a nice job for tomorrow! Thanks for the advice so far, I'll give them all a try - unless it comes off at the first attempt ![]() |

If it doesn't move with a small amount of heat and force your idea of putting the pinion in a vice and using a punch to remove the shaft from it is probably the safest for the motor. Tried to lever a stuck pinion off a brushed motor once... managed to move the shaft in the armature about 10mm before I realised it wasn't the pinion moving

Easy fix for this is to clamp the pinion in a vice then place an old allen key onto the motors shaft and gently tap it with a hammer to push the shaft out of the pinion. Any of the other suggestions may damage the motor at least this way all that will get damaged is the pinion
