Improve Gear Engagement with Arrowmax AM-364042

The Arrowmax AM-364042 pinion is engineered to maintain accurate gear mesh in RC transmissions. Constructed from 7075 aluminium, this 42-tooth 64 pitch pinion combines strength with reduced mass for consistent running.

Material Quality and Wear Resistance

7075 aluminium provides superior strength for aviation-grade alloys, and the hard anodised surface resists abrasion during routine operation. This makes the pinion a sensible choice for hobbyists seeking durable gearing.

Application and Ratio Notes

Intended for 64 pitch systems, the 42T configuration yields a moderate gear ratio suited to a range of driving conditions. It is a practical choice when modifying final drive characteristics without altering other drivetrain parts.

Is this pinion suitable for competitive use?

The 7075 aluminium construction and hard anodised finish provide durability appropriate for club and local race use, although extreme duty may require hardened steel options.

How do I check for correct installation?

Ensure the motor mount allows fine adjustment, set a small amount of sideplay or use a strip test, and confirm even tooth contact with the spur before final tightening.

Can I reuse this pinion after heavy running?

Inspect teeth for rounding, burrs or fretting; if wear is visible you should replace the pinion to avoid damaging the spur or causing poor mesh.
