Team Associated RC18T 55T Plastic Spur Gear RC18-031A by 3Racing  [RC18-031A]

RC18T spur replacement

This 55-tooth plastic spur gear is supplied as a drop-in replacement for the Team Associated RC18T gearbox and uses the RC18-031A part number. It is intended to replace a worn or damaged spur when uneven tooth engagement, vibration, or drivetrain noise signals the need for service.

Fitting is straightforward for those accustomed to 1/18 scale touring truck gearboxes: remove the gearbox cover, inspect the motor pinion and bearings for wear, fit the spur so the teeth mesh cleanly with the pinion, and check for free rotation before closing the box. As a plastic spur, confirm correct mesh and small backlash on the first runs and recheck after a few laps to ensure steady performance.

Changing to the 55T spur alters the overall ratio versus smaller or larger spurs, so expect changes in acceleration and top speed when testing gearing. Use this item as a direct replacement or as part of incremental gearing adjustments during setup work on track or at practice sessions.
