Durable Precision from HUDY 294021 Aluminium Pinion

The HUDY 294021 Aluminium Ultra-Light Pinion Gear blends robust construction with reduced rotating weight for controlled driveline behaviour. Built from 7075 T6 aluminium and given a protective hard coat, it is suited to users seeking long-term reliability in their gearing choices.

High Fidelity Tooth Machining for Better Tracking

Produced on specialised gear machines, each pinion benefits from consistent tooth shaping and accurate runout control. This leads to steady, low-vibration performance. The internal threading is neatly formed to simplify secure mounting on the motor shaft.

Visible Tooth Numbering for Efficient Setup

To assist quick selection, tooth counts are clearly marked on each pinion. This makes preparing spares and changing ratios during a practice session much faster.
Remark :
Due to limited stock availability, please notice that some HUDY items may have to order from the factory and the ready time is around 8-12 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit most standard pinion shafts?

Compatibility depends on your motor shaft diameter and thread. The HUDY 294021 is common in many setups, but confirm your shaft specs before fitting.

How often should I inspect the pinion for wear?

Check the pinion after every few runs for signs of rounded or chipped teeth, especially after hard use. Early detection prevents secondary damage to the spur gear.

Can I polish the hard coat if scratched?

Minor surface marks can be gently cleaned, but avoid aggressive polishing that could remove the hard coat. Replace the pinion if scratches affect tooth shape or performance.
