Precision Spur Gear for TRF417 Racing

The Tamiya 51440 - TRF417 111T Spur Gear is a maintenance staple for racers who keep their TRF417 chassis performing at pace. Made for an exact fit, it helps maintain smooth engagement and reliable operation during competitive runs.

Chassis Compatibility and Tuning

This spur gear fits the TRF417 chassis only and installs to maintain correct gear mesh. Used with appropriate pinion options, it supports a wide spread of gear ratios to suit tight technical circuits or faster flowing tracks. Suggested pinion choices span 24T to 45T so you can tune acceleration versus top speed.

Will this spur gear fit other Tamiya models?

This spur is produced specifically for the TRF417 chassis and is not a drop-in for other models without modification.

What pinion range should I try first on asphalt tracks?

For smoother asphalt, start with mid to higher pinion sizes such as 34T to 40T to favour top speed, then adjust down for better acceleration as needed.

Any setup tips when replacing the spur gear?

Check gear mesh with the motor installed, set a small backlash for smooth running, and inspect bearings and pinion fit to avoid premature wear.
