Replacement Spur Gear — Yokomo YOKSG6493 93T 64-Pitch  [YOKSG6493]

Replacement Spur Gear — 93 Teeth, 64-Pitch

This 93-tooth spur is built for 64-pitch RC gear trains and is offered as an aftermarket replacement driven gear. It is intended for standard repairs and for fine-tuning the drivetrain ratio where appropriate.

The component follows the 64-pitch specification, so installation needs a matching 64-pitch pinion and suitable gearbox spacing. It is intended to replace worn 93-tooth spurs in compatible gear trains.

Fitting advice: ensure correct radial and axial mesh, confirm the spur is properly seated on its hub, and manually rotate the drivetrain to check for smooth engagement and no binding. Inspect tooth faces after initial running and make sure retention hardware is secure.

Effect on performance: a 93-tooth spur shifts the final ratio and can be used to favour acceleration or lower top speed depending on chosen pinion sizes, within the constraints of a 64-pitch arrangement.
