Track-Ready Aluminium Pinion for Serpent

Enthusiasts working on the Serpent Eryx 411 can rely on the Serpent 120170 aluminium motor pinion to keep the drivetrain predictable under race conditions. Built for accurate tooth alignment, it supports consistent transmission of motor torque.

Precision Machining for Consistent Transfer

The Serpent 120170 pinion carries a 48-pitch, 31-tooth specification to promote smooth, controlled power delivery. Hardened aluminium construction reduces rotating mass while offering improved resistance to normal wear.

Compatibility and When to Fit

This part is a direct replacement for the Serpent Eryx 411 4.1 Touring Car EP and does not require extra modification. Use it as a maintenance swap or as part of setup changes for competition.

Does this pinion need special break in?

No special break in is required. After installation check gear mesh and run at low power initially to confirm there are no unusual noises or binding.

Can I modify the pinion to save weight?

Avoid altering tooth profiles or removing material that could change geometry. Any modification risks poor mesh and accelerated wear, so use the pinion as supplied.

Are special tools required to fit this pinion?

Fitting typically uses standard pinion nuts or a pinion holder used for the Eryx 411. Ensure you set mesh properly and torque the pinion fixing to avoid slippage.
