Rugged Aluminum Pinion Built for Track Use

The Serpent 120126 Aluminum Motor-pinion Gear is crafted for the Eryx 411 4.1 Touring Car EP, giving a durable replacement for hobbyists who want more consistent gear meshing. Made from high-quality aluminum, this pinion helps reduce wear while keeping weight low for dependable service intervals.

Accurate Teeth for Smooth Power Delivery

This 64P 39T pinion is precision-machined to support efficient power transfer and to limit unnecessary drivetrain wear. The tooth count allows targeted changes to gear ratios so you can adjust for acceleration or top speed based on track conditions.

Straightforward Fitment to Eryx 411 4.1

Designed to match the Serpent Eryx 411 4.1 Touring Car EP mounting and dimensions, model 120126 installs without major modification so you can swap pinions quickly between sessions.

Will this pinion fit non-Serpent cars with the same pitch?

It can fit other cars that share the same 64P pitch and compatible bore size, but you should confirm shaft diameter and mount clearance before installing.

How do I check gear mesh after installation?

Set the motor in place, apply a thin film of grease to the spur, rotate the gears by hand and look for even contact across the tooth face; adjust motor position until the mesh is correct.

What maintenance keeps this pinion lasting longer?

Regularly clean debris, inspect for chipped teeth, and ensure proper mesh and lubrication. Replace the pinion if you notice rounding or heavy wear on the teeth.
