Yokomo YOKRP-036-26 Motor Pinion 26T - Performance Tuning Gear  [YOKRP-036-26]

26-Tooth Hardened Steel Pinion

This 26-tooth pinion is offered as a precise replacement part for R/C motor drivetrains and is intended only for scale model use. Swapping pinion tooth counts lets you change the final drive ratio, tune acceleration versus top-end speed, and better match motor characteristics with your spur gear.

Confirm shaft diameter and gear pitch compatibility prior to fitting. Achieve correct mesh by setting the teeth to engage without binding, tighten the set screw, and then verify smooth operation while rotating the drivetrain. A small clearance at rest that closes under throttle often yields better results than an overly tight mesh.

For routine care, inspect the teeth for wear or chips and replace the pinion if defects are detected. Use a minimal amount of gear-specific lubricant only when compatible with the spur material, and keep the gear area clear of dirt and grit.

A 26T choice typically provides a middle-ground tuning option; pair it with your spur gear to tweak performance while keeping an eye on motor temperature and ESC load during testing.
