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

Technical Spur Ring for F103RM

This 64-pitch POM spur ring is a direct replacement compatible with the TAMIYA F103RM gearbox layout. Manufactured to provide repeatable tooth form, it is suitable for racers and tuners who prioritise consistent engagement and easy maintenance.

In operation the ring provides the mating surface for the motor pinion, preserving the required 64-pitch geometry. POM is chosen for its low friction coefficient and steady wear profile, which makes setup verification and repeatability easier during tuning sessions.

Setup recommendations: use precise shimming to establish correct mesh on the F103RM, measure backlash with feeler methods common to race preparation, rotate the drivetrain under load-free conditions to confirm uniform contact, and monitor tooth wear as part of routine inspections.
