Upgrade Your Drive Train with a Tough Steel Pinion

For focused RC racers aiming to improve drivetrain longevity, the Tamiya 51031 TGM-03 Hard Steel Pinion 17T (MJ3) brings a hardened steel tooth profile that resists wear under race conditions. Its 17-tooth layout mates cleanly with common spur gears to deliver steady power transfer while reducing premature wear.

Precision Fit for TGM-03 Setups

The Tamiya 51031 pinion is made to seat correctly in TGM-03 chassis, giving accurate tooth engagement and reliable mesh without awkward adjustments. Whether replacing a worn pinion or fine tuning gear ratios, this steel gear works well for club racers and experienced hobbyists.

Suited to Short Circuits and Sprint Runs

Built for repeated high-speed runs, the hard steel construction withstands heat and torque from stronger motors. Fitting this pinion helps maintain cleaner gear action and more consistent acceleration, which supports tighter throttle control on the track.

How do I check gear mesh when installing this pinion?

Start with motor mount shims and a thin layer of gear marking compound on the spur teeth. Rotate the drivetrain slowly to inspect contact, then adjust shims until you see even tooth contact across the face.

What maintenance does a steel pinion need?

Steel pinions are low maintenance but check for burrs and debris after rough runs, clean with a brush, and replace if you notice chipped teeth or excessive wear.

Can I use this 17T pinion with a brushless motor?

Yes, it works with brushless setups; just confirm your desired gear ratio and motor pinion size to avoid overloading the drivetrain or overheating the motor.
