T3-01 tuning spur, 39 teeth

This Factory Pro FP-O-AP0007 39T main spur is specified for use with O-AP0004 and the Tamiya T3-01 chassis. As the main spur it transfers motion from the pinion to the gearbox and has a direct effect on final gearing and vehicle behaviour.

Fitment notes: install the spur onto the gearbox input plate in line with your chassis service instructions, verify pinion-to-spur mesh through a full revolution to detect any tightness, and secure set screws to the gearbox supplier's recommended torque. Confirm the drivetrain rotates freely and remove any debris before running.

Tuning tip: swapping spur tooth counts will change the overall ratio when combined with different pinions, which is a predictable method to dial in more acceleration or higher top speed for various track layouts.

Is this spur compatible with stock T3-01 gearboxes?

The FP-O-AP0007 is listed for O-AP0004 and Tamiya T3-01 applications. Confirm spline count and mounting dimensions against your gearbox to ensure direct compatibility.

Any tips for preventing gear noise after install?

Set an even mesh, avoid over-tightening the set screws, and check for burrs or foreign matter on both pinion and spur. Proper lubrication and correct mesh reduce noise and wear.

When should I change pinion size with this 39T spur?

Adjust the pinion to reach your target ratio after fitting the 39T. Use smaller pinions for tighter tracks and larger pinions when you need more top speed, and monitor motor temps after each change.
