What It Is / How It Works

This pinion gear puller is a metal tool for removing a pinion gear from a small motor shaft. It is supplied as one piece and is designed for removing bearings, inner rings and other dense components on a car.

Who It's For / Use Cases

Pinion gear pullers suit hobbyists and repair workers who service remote control models and small motors. They are used when a gear is pressed tightly onto a shaft and cannot be removed by hand, so a puller with several pin sizes helps match different motor shafts.

How to Use / Care

1. Heat a glued gear first to melt the glue before pulling it.
2. Choose the pin that matches the motor shaft diameter. A pin that is too small for the shaft can break the ejector pin.
3. Select the thimble you need, install the rotating rod, and tighten the screw. For a table thimble, do not overtighten the screw.
4. Clip the motor into the traveling plate and move it until the motor shaft aligns with the ejector pin. Rotate the lever uniformly in a clockwise direction to pull out the gear.

How to Choose

Measure the motor shaft diameter first and pick the pin size that matches it from the five sizes listed in the specifications.
