Yokomo YOKPG4826 Precision 26T 48 Pitch Motor Pinion  [YOKPG4826]

Precision Motor Pinion — 26 Teeth, 48 Pitch

This 48 pitch, 26-tooth pinion gear from Yokomo is built as an RC motor pinion to deliver predictable gear ratio changes. The ultra-hard description indicates it is intended to provide superior wear resistance relative to softer pinions and to retain its tooth profile during repeated hobby electric RC duty cycles.

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.
