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

Replacement 57T spur for RC18T drivetrain

This 57T plastic spur gear, RC18-031B, fits the Team Associated RC18T chassis as a direct spare part. It installs in the stock spur location and keeps the original gearbox architecture intact.

The spur transmits rotation from the pinion through the gearbox, and this 57-tooth plastic unit serves as a like-for-like replacement when the original shows wear or damage. The molding matches common scale plastic gear profiles for predictable mesh and engagement.

Fitment and setup notes: remove the gearbox following the RC18T service sequence, set pinion mesh carefully, confirm free rotation of the motor and gearbox bearings, and check for binding before final assembly. If you change pinion sizes to alter gearing, always recheck mesh and clearances.
