1/48 Steel 22T Pinion Gear - Kyosho UM322C  [KY-UM322C]

Precision 22T steel pinion for 1/48 models

This Kyosho UM322C steel pinion gear is offered as a direct replacement for 1/48 scale RC models that require a 22-tooth motor pinion. It ships as a single spare pinion to restore drivetrain accuracy or to fine-tune mesh where tooth count and material consistency matter.

The design retains the tooth profile and spacing expected from a 22T pinion in small-scale motors, so it is suitable for matching existing gear sets or experimenting with mesh and gear ratio adjustments on 1/48 platforms. Always verify tooth count and mesh clearance against your existing spur gear before fitting.

Installation guidance: check the motor shaft and whether the pinion uses a set screw or press-fit arrangement, confirm axial position and backlash, and trim or shim the motor mount if needed to get proper mesh. Do not assume shaft diameter or set screw type—measure the existing assembly before installation.

Fit this pinion when replacing a worn 22T steel pinion or when modifying final drive ratios on a 1/48 scale RC setup, and always confirm fitment and gear mesh before operating.
