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

64Pitch POM Spur for F103RM

This 64-pitch spur ring is supplied for use with the TAMIYA F103RM layout and matches the on-road gearbox geometry. The component is moulded from POM to deliver consistent tooth shape and predictable wear for routine service or tuning swaps.

Functionally the ring forms the spur surface for the motor pinion and preserves the expected 64-pitch mesh characteristics. POM is selected for its low friction and steady sliding behaviour, which helps reduce noise and keeps mesh stable under normal on-road loads.

Fitting tips: set spur-to-pinion mesh using standard shims on the F103RM, verify backlash and rotate the drivetrain by hand before applying power, and replace the ring if you detect chipped or uneven teeth. Treat this as a maintenance or tuning spare to keep gear engagement correct on F103RM cars.
