YOKPG4829 Precision 48 Pitch 29T Pinion Gear by Yokomo  [YOKPG4829]

Performance and Fit

A compact, RC-scale precision pinion designed specifically for 48 pitch gear trains. The YOKPG4829 offers stable tooth form and hardened material to keep mesh stable under typical electric model stresses.

Application: mount the pinion on the motor shaft to modify gear ratio, tune acceleration versus top speed, and optimise mesh when refining drivetrain efficiency. It acts as a direct replacement for worn or softer pinions.

Fitting tips: install on a clean, deburred motor shaft, locate the set screw on a shaft flat when possible, and use proper shimming to set desired backlash. Perform a few low-throttle cycles to confirm engagement before locking hardware. Light running-in can help seat the gear.

Tuning notes: the ultra-hard surface reduces wear compared to softer gears but requires precise spur alignment to avoid tooth damage. If you increase or decrease tooth count, always re-check mesh and motor timing where relevant.
