Refine Your Gear Train with Tamiya 40505

The Tamiya 40505 Aluminum Pinion Gear is made to refine power delivery in your RC. Its aluminium construction and 18-tooth profile reduce rotating weight and promote smoother engagement between motor and spur gear.

Performance Benefits of an Aluminium Pinion

Using an aluminium pinion can lower motor load and improve throttle response, helping acceleration and handling feel sharper. The Tamiya 40505 provides a solid option for racers and weekend tuners alike.

Compatibility Notes for Common Builds

This pinion works with many 1/10 scale builds and standard motor mounts. Always double-check shaft diameter, secure the pinion firmly, and set correct mesh to prevent skipping or premature wear.

Will this pinion change my gear ratio much?

The tooth count determines ratio; swapping to an 18T pinion from a different size will alter acceleration and top speed, so calculate the change before fitting to match your goals.

Are spare clamping collars needed?

Most installs reuse the existing collar, but having spare collars or set screws available helps ensure a secure fit and quick swaps during setup sessions.

How often should I inspect the pinion?

Inspect the pinion and spur gear regularly after running in dusty or wet conditions; look for chipped teeth or excessive wear and replace as needed to protect the gearbox.
