Tamiya T3-01 39T Spur Gear for Tuning - Factory Pro FP-O-AP0007  [FP-O-AP0007]

Upgrade spur designed for T3-01 setups

The Factory Pro FP-O-AP0007 39T main spur is produced for compatibility with O-AP0004 and the Tamiya T3-01 chassis. As a 39-tooth spur, it transmits pinion rotation into the gearbox and influences the final drive behaviour on track.

Installation guidance: mount the spur on the gearbox input plate per your chassis manual, check mesh around a full rotation to identify any tight areas, and tighten set screws to the gearbox manufacturer's torque guidance. After fitting, ensure the drivetrain turns freely and clear away any grit before running.

Setup advice: changing spur tooth count changes the final ratio when paired with different pinions, giving a straightforward method to prioritise acceleration or top speed based on venue and motor choice.
