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

93-Tooth Replacement for 64-Pitch Systems

This 93-tooth spur is made for 64-pitch RC gear trains and is supplied as a direct replacement for the driven gear in common gearboxes. It suits routine maintenance and modest tuning adjustments.

Fitment depends on the 64-pitch specification, so you will need a matching 64-pitch pinion and compatible gearbox spacing. Use it wherever a 93-tooth 64-pitch spur is required by the drivetrain design.

Installation guidance: confirm correct gear mesh by checking radial and axial alignment, ensure the spur sits square on the hub, and rotate the drivetrain slowly to check for smooth engagement and no binding. After initial runs, inspect tooth faces for uneven wear and ensure set screws or retention features are secure.

Tuning role: a 93-tooth spur alters the final ratio and is useful for trading top speed against acceleration; select pinion sizes to reach the desired drive characteristics within a 64-pitch setup.
