Precision Machined 48P Pinion

The Serpent 120156 48P Aluminium Pinion Gear is an 18-tooth component engineered for accurate engagement and efficient transmission of power. Its machined profile supports smoother acceleration and consistent operation.

Hardened Aluminium Benefits

Hardened aluminium construction reduces rotating mass while offering improved thermal behaviour under load, helping maintain gear integrity during repeated runs and competitive use.

Ideal for Ratio Tuning

Designed to pair with 48 pitch spurs, the Serpent 120156 makes changing gear ratios straightforward, giving builders clear tuning options for speed or torque adjustments.

Will this pinion fit my standard 48 pitch setup?

Yes. The Serpent 120156 is made for 48 pitch systems and will fit most standard 48P spurs used in 1/10 scale models, subject to shaft diameter compatibility.

How do I check for correct mesh after installation?

With the gears installed, rotate slowly by hand and inspect tooth contact across the face. A small, even contact patch is ideal; adjust shims or motor position to correct any irregularity.

When should I replace the pinion?

Replace the pinion if you notice rounded teeth, significant pitting or metal fatigue. Regular inspections after intensive runs will help spot wear early and avoid spur damage.
