Serpent 48P 39T Aluminium Pinion for Reliable Drive

The Serpent 48P 39T aluminium motor pinion delivers dependable gear engagement for RC racers and weekend builders alike. Its construction is suited to a range of electric motor installations where consistent meshing matters.

Advantages of Aluminium Pinion Gears

Aluminium offers a good compromise of lightness and toughness, helping reduce inertia while still standing up to typical running forces. That makes it a go-to option for many tuners.

Fitment Notes and Uses

The 39 tooth, 48 pitch design is compatible with many electric car setups, offering precise ratio choices for both on-road and off-road tuning. Use it to fine tune acceleration or top speed characteristics.

What motors are compatible with 48P pinions?

Most motors that accept 48 pitch pinions will work with this gear. Check your motor shaft diameter and the spur gear pitch to ensure a correct match.

How is the pinion secured to the motor shaft?

Pinions are typically clamped with a set screw or held with a grub screw and possibly a pin. Make sure the screw tightens against a flat on the shaft and use threadlocker if needed.

Can I use shims to adjust mesh with this pinion?

Thin shims or washers between motor mount and chassis can help fine tune the mesh. Small, careful adjustments yield a clean contact pattern.

How often should I inspect the pinion?

Check the pinion after every few sessions, especially after off-road runs. Look for chipped teeth, burrs, or loose screws and replace if wear is evident.
