Fine tuning with the Serpent 120139 pinion

The Serpent 120139 Aluminum Pinion Gear is made for RC hobbyists who want reliable, long lasting performance. Machined from hardened aluminium, this 64-pitch, 52-tooth pinion offers precise tooth engagement and reduced wear for track days or practice sessions. Use it to dial in gear ratios, smooth out drive train noise, and improve drivetrain consistency.

Advantages to consider

Choosing the right pinion affects acceleration, top speed, and drivetrain feel. The Serpent 120139 delivers clear benefits:

Material: Hardened aluminium construction for strength and extended service life.
Design: 64P with 52 teeth for accurate mesh, quieter running, and efficient power transfer.
Compatibility: Works with many RC car motor setups and can be swapped in for tuning experiments.

Can I use this pinion with high KV brushless motors?

Yes. The Serpent 120139 handles both brushed and brushless setups; just check shaft fit and ensure proper backlash for your gearing and motor RPM.

How do I confirm the pinion fits my motor shaft?

Measure your motor shaft diameter and compare it with the pinion bore or use a dial caliper to confirm an interference or set screw fit before installation.

What maintenance keeps this gear working well?

Keep the pinion free of grit, check mesh regularly, and inspect for tooth wear. Replacing the pinion at the first signs of rounded teeth preserves the spur gear and motor.
