57T spare spur for competitive RC18T setups

The RC18-031B 57T plastic spur is provided as a service spare for the Team Associated RC18T, intended for use in the standard spur position to retain gearbox geometry. It is a pragmatic replacement for damaged or worn stock gears during race preparation and maintenance.

In tuning contexts the spur transmits torque from the pinion into the gearbox; this 57-tooth plastic unit preserves predictable engagement characteristics, which helps when testing pinion changes and final drive options. Use consistent mesh checks to keep repeatable drivetrain behaviour across setups.

Workshop guidance: follow the RC18T strip order, install the spur and set precise pinion mesh, confirm bearings and motor rotate without drag, and validate no tooth interference before track use. When altering pinion size to tune acceleration or top speed, re-evaluate mesh under manual rotation and after a short run to confirm reliability.

How does the 57T affect gearing choices?

The number of spur teeth sets the base ratio with your chosen pinion; keeping the stock 57T makes it simple to compare pinion changes without altering the baseline gear circumference.

Best practice for mesh in a race car?

Set mesh to give slight tooth clearance, then verify under manual rotation and after a short run; repeatability in mesh is key to consistent lap times and drivetrain longevity.

When should the spur be replaced between events?

Inspect before each event for tooth wear or deformation; replace the spur if tooth profile is compromised or if you detect slippage or unusual noise under load.
