Refine Drivetrain Feel with Serpent SER120176

The Serpent SER120176 Motor-pinion Aluminium Hard 48P / 38T is a practical choice for builders who want durable performance without extra weight. The hard-anodised aluminium construction keeps teeth true while reducing mass in the rotating assembly.

Lightweight Benefits of Aluminium

Using an aluminium 48P 38T pinion reduces rotational inertia, helping the motor accelerate more responsively. The hard finish also helps resist abrasion from grit and frequent running.

Fitment and Typical Use

Made for motors that take 48 pitch pinions, the 38-tooth configuration is well suited to mixed-use driving. Whether you are fine-tuning a racer or upgrading a basher, this pinion offers a sensible gearing option.

Do I need to change my spur gear when switching to this pinion?

You do not always need a new spur, but check overall gear ratio and mesh. If the new pinion changes required torque or clearance, consider a matching spur to maintain proper engagement.

Any tips for setting gear mesh?

Set the mesh with a single sheet of paper between pinion and spur, tighten the motor mount, then remove the paper and verify there is a small amount of backlash. Recheck after a short run.

Is aluminium prone to wear compared to steel?

Aluminium is lighter but softer than steel, so wear can occur faster in high-load situations. The hard-anodised surface improves wear resistance, making this pinion a good all-round option.
