Tamiya TRF 416 Rear Drive Belt 416-14 for upkeep by 3Racing  [416-14]

Replacement rear belt for TRF 416 use

This rear drive belt is supplied for the Tamiya TRF 416 and listed as part 416-14. It is a like-for-like wear item intended to replace a tired belt and maintain predictable drivetrain performance rather than to add unrelated features.

Function and fit: the belt replaces the factory rear drive belt on TRF 416 rear belt assemblies, restoring proper engagement between the spur and the rear pulleys. Keeping the belt in good condition helps preserve consistent acceleration and lap times.

Fitting notes: remove the rear bulkhead or lower chassis cover following your TRF 416 service practice, release belt tension at the idler or motor mount, remove the worn belt and refit the replacement along the factory route, then set correct tension and verify pulley alignment. Check pinion to spur mesh before finishing assembly.

Maintenance advice: belt wear affects throttle response and consistency; inspect for glazing, edge wear or slack after prolonged sessions and renew as needed. Set tension to remove excess play while avoiding excessive preload that can stress bearings or the motor shaft.
