Precision aluminium pinion for competitive gearing

The Serpent 120133 is an accurately machined pinion gear in aluminium, cut to a 64-pitch 46-tooth specification to ensure smooth torque transfer. It is intended for users who prioritise predictable gear interaction and proven durability on the track.

Performance and wear resistance

Finished with a hard anodised surface, the Serpent 120133 provides improved abrasion resistance while keeping weight down. The faithful tooth geometry reduces shock loading and helps maintain steady drive efficiency over time.

Which kits will this fit and how to install

This pinion suits a wide selection of RC models that run 64-pitch gears. Installation is normally quick with common RC tools; confirm shaft fit and mesh pattern after mounting to achieve quiet, efficient operation.

How do I confirm shaft compatibility?

Measure your motor shaft diameter and check the pinion bore or adapter. The Serpent 120133 requires a matching shaft or the correct adapter to secure the pinion properly.

Does anodising change gear fit?

Anodising adds a thin surface layer but is not likely to affect fit if the pinion was machined to correct tolerances. Always check fit and mesh after installation.

What gear oil or grease should I use?

Use a light gear grease or lubricant recommended for spur and pinion gears to reduce friction and help the Serpent 120133 run quietly without gumming up the teeth.

When should I replace the pinion?

Replace the pinion if you notice rounded tooth edges, chipped teeth, or persistent noise after correct mesh adjustment. Early replacement protects the rest of the drivetrain.
