Precision Pinion Upgrade for TA-04

The Tamiya 49233 - 0.4 Aluminum Pinion Gear is a solid choice for hobbyists aiming to refine their TA-04 setup. Machined from hard-coated aluminum, the gear gives good wear resistance and consistent tooth shape to help maintain accurate mesh.

Core Benefits

Durable Construction: The hard-coated aluminum body resists wear from regular running while keeping weight low.
Stamped Size: The tooth count is clearly stamped on the pinion, making it quick to identify when changing ratios.
Model Compatibility: Made with the TA-04 and Tamiya GP fixed gear ratio class in mind for straightforward fitment.

Fitting and Setup

The pinion includes two set screws for a secure connection to the motor shaft. When installing, check gear mesh and tighten the set screws evenly to avoid slippage and maintain reliable performance.

Will this pinion fit other Tamiya motors or cars?

This pinion is designed for TA-04 and Tamiya GP fixed ratio setups but can fit other models if the motor shaft diameter and 0.4 module pitch match. Always verify shaft size before fitting.

How do I check the pinion size quickly?

The tooth count is stamped on the gear face so you can confirm 39T at a glance during maintenance or when swapping ratios.

Any tips for preventing slippage after install?

Ensure the set screws are tightened onto a clean, flat section of the motor shaft and check mesh under load. Apply a thread locker rated for metal if you want extra security, and recheck after a few runs.
