Yokomo YOKRP-036-26 Precision 26-Tooth Pinion for Model Drivetrains  [YOKRP-036-26]

Exact-Fit 26 Tooth Pinion

This 26-tooth pinion is supplied as a precision replacement for R/C motor drivetrains and is intended for scale model applications only. Changing pinion tooth count is a straightforward way to alter final drive ratio, trade acceleration for top speed, and better align motor output with your spur gear.

Before installation, confirm both shaft diameter and gear pitch are compatible. Proper mesh is essential—set the pinion so the teeth engage cleanly without binding, secure the set screw, and re-evaluate mesh while the drivetrain is turning to ensure stability.

For upkeep, inspect the gear teeth for wear, nicks, or missing material and replace the pinion if problems are found. Apply a light, appropriate gear lubricant only when compatible with the spur, and keep the gear area clean to avoid premature wear.

Choosing a 26T pinion is often a balanced tuning step; combine it with your current spur gear to fine-tune performance and monitor motor temperature and ESC load during test runs.
