FF-03 Counter Gear 20T for TAMIYA FF03-03 by 3Racing  [FF03-03]

Replacement 20T counter gear for FF-03

This 20T counter gear is supplied as a replacement part for TAMIYA FF-03 chassis gearbox assemblies. It acts as the counter or secondary gear that engages the spur and pinion to set drive ratio and transfer motor torque through the gearbox.

Intended for FF-03 compatible gear trains that take a 20-tooth counter gear; always verify your original part profile and mounting arrangement before installation. The gear is commonly used to repair worn teeth or to refine gearing for specific circuit demands.

Fitting requires standard gearbox service steps: remove the cover, extract the old counter gear, inspect bearings and shafts for signs of wear, install the new gear ensuring correct backlash and tooth mesh, and reassemble. Carry out a brief test run and then recheck gear engagement to confirm smooth operation and to prevent early failure.
