Spare Pinion for Tractor Truck Models

The Tamiya 3505039 10T pinion is supplied as a direct replacement for the Tamiya 56301 tractor truck, designed to restore accurate power transfer from the motor to the gearbox. The correctly profiled teeth help maintain consistent running characteristics.

Accurate Mesh and Reliability

Produced to precise tolerances, the Tamiya 3505039 delivers stable engagement and good service life under standard hobby use. Its 10-tooth design is suited to the tractor truck drivetrain geometry for straightforward installation.

Easy Replacement for Maintenance

Fit this pinion during scheduled servicing or when optimising gear ratios. A new pinion can reduce wear on mating parts and keep drivetrain noise and slop to a minimum.

Will changing to this pinion alter speed significantly?

Swapping the pinion to the same tooth count keeps the overall ratio unchanged, so top speed should remain similar. Changing tooth count will affect speed and torque balance.

How do I secure the pinion to the motor shaft?

Locate the set screw in the pinion, align it with any flat on the motor shaft, and tighten firmly. After installation, rotate the gears by hand to confirm smooth, even mesh.

When should I replace the pinion?

Replace the pinion if teeth show rounding, cracking or uneven wear, or if gear noise increases. Timely replacement protects the spur gear and motor pinion interface.
