Yokomo YOKPG4826 Precision Pinion Gear 48 Pitch 26T Ultra-Hard  [YOKPG4826]

Precision 48-Pitch 26T Pinion Gear

This is a 48 pitch, 26-tooth pinion gear from Yokomo designed as an RC-scale motor pinion for precise gear ratio adjustments. The part is described as ultra-hard, intended to provide improved wear resistance compared with softer pinions, and to maintain tooth profile under repeated load cycles typical in hobby electric RC use.

Use this pinion where a 48 pitch pinion is required by the motor and spur gear combination. It is intended only for RC motor output shafts and gearbox gearsets that accept 48 pitch pinions; do not use it with incompatible pitch systems.

Installation and tuning tips:

• Check shaft fit and keying before tightening, ensure the pinion seats fully on the motor shaft to avoid axial play.
• Set gear mesh carefully using standard methods: correct clearance avoids premature tooth wear while preventing binding under load.
• When changing tooth count, remember each tooth increment alters the overall gear ratio, trading top speed for acceleration or vice versa depending on direction of change.
• Inspect the mating spur gear for wear and compatibility with 48 pitch teeth to preserve smooth operation.
