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

Stock-style 57-tooth spur for RC18T

The 57T plastic spur RC18-031B is intended as a spare for the Team Associated RC18T, fitting the standard spur location without modifying the gearbox footprint. It is a straightforward replacement part for wear-related service.

As a drivetrain part the spur transfers torque from the pinion into the gear train; this 57-tooth plastic piece replicates stock engagement and is suitable for standard driving conditions. Moulding and profile follow common scale plastic gear patterns to keep predictable mesh behaviour.

Practical installation notes: remove the gearbox following the chassis guide, set the pinion mesh carefully, confirm the motor and bearing assemblies rotate freely, and check for any binding before final tightening. If you change pinion sizes to adjust final drive ratios, verify mesh and clearance after each swap.
