Precision Pinion Gear 20T Yokomo RP-036-20  [YOKRP-036-20]

Adjust gearing with a 20T pinion

This 20-tooth pinion is an accessory for electric pinion and spur gear systems, used to alter the final drive ratio so you can tailor acceleration and top speed without changing the motor.

As a replacement component, the pinion is compatible with standard spur-and-pinion arrangements on electric R/C models. When fitting, verify shaft fit and establish an even mesh with the spur, keep a small clearance across the tooth faces, and secure the pinion firmly to the motor shaft.

It is ideal for making small gearing changes during setup or practice. Routine steps include confirming the shaft diameter match, rechecking mesh after several runs, and inspecting bearings and the spur for signs of wear.
