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

Small-scale 22-tooth steel pinion

This Kyosho UM322C steel pinion gear is a spare part option for 1/48 scale RC models that utilise a 22-tooth motor pinion. It is supplied as an individual replacement to restore correct drivetrain operation or to permit fine adjustments to gear meshing and ratios.

The component is intended to maintain the expected tooth profile and spacing for a 22T pinion in compact motors, so it works well when matching current gear sets or experimenting with mesh and gear ratio changes on 1/48 platforms. Always check tooth count and mesh clearance against the spur gear before fitting.

Fitting notes: examine the motor shaft and whether the pinion secures via set screw or press-fit, confirm axial placement and backlash, and trim or shim the motor mount where required to obtain correct mesh. Measure shaft diameter and set screw type before attempting installation.

Use this 22T pinion when replacing worn parts or adjusting final drive ratios on a 1/48 scale RC model — always confirm fit and mesh prior to running.
