Motor Pinion Gear Puller Remover Tools Set For Rc Helicopter Motor Pinion Parts

Good quality, all the pieces are made of metal and it comes in various sizes. I’m attaching a photo so you can get an idea of the size.

GarbageDamn thing isn’t threaded right. I can’t even move the plunger part with vise gripsDefinitely disappointed

Rotary bar missing from kit.

Five Stars for quality. Smooth finish on tool.It didn't work for my situation. It has an 11mm opening. I needed it for a 3d printers stepper motor; to remove the pulley. The pulley was 16mm wide. I had to grind the pulley to 11mm in order to use the tool. Still, well worth it. Very easy to use. All in all, not ideal for 3D printers.

Did not come with pins

I used the puller to remove the pinion gear from a small, 130 size motor from an RC tank. I had tried heating the gear and prying it off with no success. I am sure I would have destroyed the motor and gear if I continued. With the puller, the gear came of using only finger pressure on the screw, very easy to set up and use, no damage to my equipment. No bending of the push pin. I did measure the motor shaft, so I could select the thickest pin that would not get stuck in the gear. I am sure I will use this again. I would buy this again.My first impression upon unpacking was that the unit was tiny, I didn't know they made gear pullers this small. There are no instructions included, this may be a blessing considering some instructions I have read.

Could not fit to remove pinion from AEG long motor. Ended up having to dremel to make the tool fit. Then after getting it started and switched to the unmodified side. That side bent. It's a 1 time disposable tool.

Works but has a learning curve to operate and some motors have very small gaps so it's hard to find leverage on some motors.
