Team Associated RC18T Plastic Spur 57T - RC18-031B by 3Racing  [RC18-031B]

57T plastic spur compatible with RC18T

This 57-tooth plastic spur, RC18-031B, is offered as a replacement for the Team Associated RC18T and is intended for the original spur position so the gearbox layout stays unchanged. It provides a stock-style option for routine maintenance.

The spur's job is to relay rotation from the pinion to the gearbox internals; this plastic 57T component restores standard tooth engagement when the worn original is removed. The geometry follows typical scale plastic gear profiles for reliable interaction with OEM pinions.

Installation checklist: disassemble the gearbox per the RC18T procedure, install the spur and set pinion mesh to factory clearance, verify free rotation of motor and gearbox bearings, and check for binding before securing covers. When experimenting with different pinions to change ratios, always reverify mesh and running clearance.
