The Yokomo YOKRP-036-24 Precision Pinion Gear 24T is built as a direct replacement or spare for electric drivetrain projects that accept a 24-tooth pinion. This precision component is intended to alter final drive ratios while delivering consistent tooth contact with matching spur gears during setup and tuning.
Fitting is straightforward for experienced modelers: remove the motor pinion set screw, slide the 24T pinion onto the motor shaft to achieve the desired mesh with the spur gear, then tighten the set screw and confirm backlash and runout. Always check engagement at low speed before running at full power and re-verify the mount after the initial test run.
In tuning practice, swapping to this 24T pinion modifies the balance between top speed and acceleration in predictable increments when used alongside spur gear changes. Maintain drivetrain bearings and spur gear surfaces in good condition to preserve performance and reduce wear.
