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

F103RM 64Pitch POM Gear Ring

This 64Pitch POM gear ring is offered by 3Racing for use with the TAMIYA F103RM chassis. It is a direct replacement-type spur gear ring made from POM as stated in the product name, intended for on-road 1/10 scale applications where the F103RM layout and gear pitch are required.

In practical terms the part serves the spur engagement role inside the gearbox assembly, providing the mating surface for the motor pinion and delivering the tooth geometry expected of 64-pitch setups. POM is chosen for its low-friction sliding characteristics and predictable wear pattern compared to softer plastics, which helps maintain consistent mesh under typical on-road loads.

Installation notes: check spur-to-pinion mesh on the F103RM chassis with the usual shimming method, verify backlash and run the drivetrain by hand before powering on, and replace if teeth show uneven wear. This ring is positioned as a service spare and a tuning-friendly replacement for maintaining correct gear engagement on F103RM cars.
