On-road 64Pitch POM Spur Ring for TAMIYA F103RM F103RM-11 by 3Racing  [F103RM-11]

POM Spur Ring for TAMIYA F103RM

This 64-pitch POM spur ring is intended for the TAMIYA F103RM chassis and fits the standard on-road gearbox arrangement. Manufactured from POM, it provides stable tooth profiles useful for both maintenance and incremental tuning changes.

As the mating surface for the motor pinion, the ring maintains the 64-pitch geometry expected by F103RM owners. POM's low friction properties and predictable wear help preserve mesh consistency during everyday running.

Installation advice: use the common shimming procedure to set spur-to-pinion clearance on the F103RM, check that backlash is within expected range, turn the drivetrain by hand to confirm smooth engagement, and replace the ring if wear or damage appears.
