Gear Upgrade for Your Tractor Truck

The Tamiya 3505039 10T pinion is a precise replacement part for the Tamiya 56301 tractor truck, designed to ensure correct engagement between the motor and the drivetrain. Its accurate tooth form helps keep acceleration smooth and reduces stress on downstream gears.

Precision Engineering

Built to consistent tolerances, the Tamiya 3505039 pinion provides dependable mesh and long service life. The 10-tooth configuration matches the tractor truck gearing requirements for straightforward installation.

Great for Servicing and Tuning

Whether you are maintaining your model or testing different ratios, swapping to this pinion is a simple way to refresh the drivetrain. Proper fitment helps lower wear on the spur gear and motor output shaft.

Can I use the 3505039 on non 56301 vehicles?

The pinion can be used on models with the same shaft diameter and mounting style, but check tooth count and shaft fit before installing to avoid improper mesh.

Do I need any special tools to fit the pinion?

Basic tools like an Allen key for the set screw and a screwdriver are usually enough. A small file or emery cloth can tidy a motor shaft flat if required for secure fixing.

How do I check gear mesh after fitting?

Fit the spur gear, then use a thin paper shim between pinion and spur to set clearance, rotate the drivetrain by hand, and make minor adjustments until the mesh runs smoothly without tight spots.
