Arrowmax AM-348046 7075 Hard 48P 46T Pinion - Durable RC Drive Gear  [AM-348046]

Accurate tooth form and durable aluminium construction

The Arrowmax AM-348046 pinion is manufactured from 7075 hard aluminium to deliver stable tooth profiles and improved resistance to wear. The 48P 46T layout provides reliable engagement with compatible spur gears.

Material benefits and expected behaviour

7075 hard aluminium gives a good compromise between weight and toughness, reducing rotating inertia while standing up to routine running loads for longer than softer alloys.

Compatibility notes and typical installations

Designed for gearboxes accepting 48-pitch 46-tooth pinions, this item pairs with matching spur gears and is commonly used when upgrading or replacing worn pinions during servicing.

Practical fitting and upkeep tips

• Set the mesh carefully, using slow rotation to check even tooth contact across the spur and pinion.
• Replace the pinion if you spot chipped or rounded teeth after heavy running.
• Use a medium-strength thread-lock on the set screw and recheck tightness after a few runs.
