R/C 88T 64 Pitch Spur Gear YOKR12-6488S Yokomo  [YOKR12-6488S]

Replacement 88T Spur with 64 Pitch Tooth Profile

This 88-tooth spur uses a 64 pitch profile and is listed under Yokomo part number YOKR12-6488S. It is intended for use as a replacement or spare in R/C gearbox assemblies that call for 64 pitch gearing.

The spur's role is to transfer motor pinion rotation through the gearbox to the final drive. Keeping the pitch and tooth count aligned with the pinion prevents uneven wear and helps maintain bearing and gear longevity.

Fitment checklist: verify the pinion engages across the full tooth face, set and confirm correct backlash, avoid axial bearing preload, and perform a brief, moderate-power run-in to settle any minor finish irregularities before demanding operation.
