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

Precise 20T gear for motor gearing adjustments

This 20-tooth pinion is designed for electric pinion-and-spur gear systems in R/C models and provides a simple way to alter final drive ratios to suit setup needs.

As a plain replacement part, it matches common pinion-spur configurations on electric R/C vehicles. During fitting, check the shaft engagement depth and ensure the mesh with the spur is even, keep a slight clearance across the tooth face, and confirm the pinion is clamped securely to the motor shaft.

Choose this pinion for small, stepwise gearing changes when dialing in performance. After installation, recheck mesh after initial runs and verify surrounding bearings and the spur gear are in good order to avoid premature wear.
