Improve Geartrain Efficiency with Tamiya 42267

The Tamiya 42267 - TRF 04 hard coat aluminum pinion gear is an effective upgrade for modders and racers focused on drivetrain efficiency. The 37-tooth, lightweight aluminium construction supports smoother power transfer and lower rotational inertia on 04 Module systems.

Hard Coat for Extended Service

The specialised hard coat enhances surface toughness so the pinion can withstand demanding use. Precision-cut teeth minimise friction at the mesh, promoting consistent engagement with the spur gear.

Fitment Guidance and What's Included

Intended for any Tamiya chassis that uses 04 Module gears, the Tamiya 42267 is supplied with a 3mm grub screw for firm fixing. It is a straightforward part swap when refreshing gearing or testing alternate ratios.

How do I check if my motor shaft will accept this pinion?

Measure the motor shaft diameter and ensure the 3mm grub screw can clamp onto it. If the shaft is undersized or oversized, use an appropriate adapter or alternative fixing.

Will the hard coat change gear noise?

The coating itself does not alter tooth profile; correct mesh settings and clean mating surfaces are the main factors in reducing noise. The hard coat may reduce wear-related roughness over time.

Can I run this pinion in wet or dusty conditions?

The hard coat improves wear resistance, but exposure to water and fine dust will still accelerate wear. Rinse and dry components after wet runs and keep gears free of abrasive debris.
