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

Direct-fit 57T spur for RC18T chassis

The 57T plastic spur, RC18-031B, is supplied as a spare for the Team Associated RC18T and is intended for the OEM spur position without changing gearbox layout. It offers straightforward swap-in fitment for routine repairs.

Functionally the spur passes rotation from the pinion into the gearbox; this 57-tooth plastic gear provides a stock-form replacement when the original is worn. The part is produced in a scale-appropriate plastic formulation to match standard engagement characteristics.

Service and tuning advice: follow the RC18T disassembly order, set pinion-to-spur mesh with a feeler or shimming method, ensure motor and gearbox bearings rotate freely, and confirm there is no binding during a manual spin. When you alter pinion sizes to tweak overall ratio, recheck mesh and clearances after each change.
