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

Replacement spur for RC18T gearing

This 55-tooth plastic spur is supplied as the RC18-031A replacement for the Team Associated RC18T chassis. It is intended to serve as a like-for-like gearbox gear when a spur shows wear, chipped teeth, or poor engagement with the motor pinion.

Installation follows standard 1/18 scale touring truck practices: open the gearbox, check the pinion and bearings for wear, position the spur for clean tooth engagement, and rotate the drivetrain by hand to confirm free movement prior to reassembly. Because the component is plastic, re-inspect mesh and backlash after a short run-in period to confirm stable behaviour.

The 55T tooth count will shift the drive ratio relative to other spur sizes, affecting launch and top-end speed. Fit this spur as a service part or to make small changes to gearing while tuning handling and motor load on the track.
