Race grade aluminium pinion for accurate gear meshing

The Serpent 120133 is a precision pinion crafted from tough aluminium, specified at 64-pitch with 46 teeth for dependable power transfer. It is aimed at tuners and club racers who want consistent tooth engagement and reduced drivetrain wear during repeated runs.

Durability through smart material choice

Constructed from hard anodised aluminium, the Serpent 120133 offers abrasion resistance while keeping mass low to aid acceleration. The fine machining on each tooth yields a smooth interface with the spur gear, cutting down vibration and extending component life.

Compatibility notes and easy install tips

Designed for 64-pitch gear systems, this pinion fits a broad array of RC models that share that pitch. Installation is straightforward with basic RC tools; take care to check shaft seating and secure the pinion set screw to maintain reliable mesh.

What benefits does hard anodised aluminium give?

Hard anodising adds a protective oxide layer that improves surface hardness and helps the Serpent 120133 resist scuffing and corrosion in normal use.

Is this pinion lighter than steel alternatives?

Yes, aluminium pinions like the Serpent 120133 typically weigh less than steel, which can reduce rotating inertia and improve throttle response.

Will it fit my 64P gearbox with a shimmed shaft?

It should fit as long as the shaft diameter and mounting style match your setup. Use shims as needed to achieve correct gear mesh before locking the pinion in place.

Any maintenance advice?

Inspect teeth regularly for nicks, keep mounting hardware tight, and ensure the mesh pattern is correct after hard impacts to prevent premature wear.
