Boost Drivetrain Efficiency with Tamiya 40505

The Tamiya 40505 Aluminum Pinion Gear is crafted to sharpen drivetrain response in your RC vehicle. Machined from aluminium to reduce rotational mass, the 18-tooth pinion helps lower wear while keeping power delivery consistent for both race and everyday use.

Advantages of an Aluminium Pinion

Aluminium pinions strike a balance between lightness and strength, helping improve acceleration and throttle feel. The Tamiya 40505 is designed to provide smooth engagement and reliable durability, making it a practical choice for tuning or replacing worn parts.

Fitment Tips and Installation

This pinion suits many 1/10 scale platforms and installs with standard clamping systems. Confirm motor shaft diameter and set proper gear mesh during installation to prevent premature wear and ensure quiet operation across different surfaces.

Is the Tamiya 40505 pinion compatible with brushless motors?

Yes, the Tamiya 40505 works with most motors that accept an 18T pinion, including many brushless setups, as long as the shaft size matches and the mesh is set correctly.

Should I lubricate the pinion gear?

Light lubrication on the spur and pinion can reduce noise and wear, but avoid heavy grease on the pinion teeth which can attract dirt and grit.

Does this pinion require shimming or spacers?

Most installs use standard spacers or clamping collars; check your motor mount and ensure correct axial position to maintain even tooth contact with the spur gear.
