Main spur suited to T3-01 chassis

The Factory Pro FP-O-AP0007 main spur gear is specified for compatibility with O-AP0004 and the Tamiya T3-01 chassis. This 39T spur conveys rotation from the pinion into the gearbox and has a clear influence on gear ratio and handling on track.

Installation notes: place the spur on the gearbox input plate following your chassis manual, inspect pinion-to-spur engagement across a full rotation to find any tight spots, and tighten set screws to the gearbox maker's recommended torque. After fitting, ensure the drivetrain rotates freely and remove any particles before test running.

Tuning overview: changing spur tooth count alters the final drive when matched with different pinions, providing a straightforward way to favour acceleration or top speed depending on the circuit and motor used.

How do I confirm this part fits my T3-01 setup?

Verify that the spur's mounting face and spline match your gearbox and that the part is listed for O-AP0004/T3-01 applications. Trial-fit before final assembly to check alignment.

What maintenance should I do after installing the spur?

After installing, keep an eye on mesh wear, clean any debris from the gear teeth periodically, and recheck set screw tightness after a few runs to maintain reliability.

Will changing to 39T change motor load significantly?

A 39T spur will alter the final ratio relative to your previous spur; pairing it with different pinion sizes changes motor RPM and load, so monitor temperatures and performance after adjustments.
