Durable 48P 18T Pinion for Serious Modelers

The Arrowmax AM-348018 Pinion Gear brings a balance of light weight and robustness to drivetrain tuning. The 18-tooth, 48-pitch format is commonly used across many motor and gearbox combinations, giving predictable results when changing ratios.

High-strength 7075 aluminium with hard finish

Produced from 7075 aluminium, this pinion offers strong mechanical properties while keeping rotating mass low. The hard anodised coating reduces surface wear and helps maintain clean tooth contact under regular use.

Wide compatibility for multiple vehicle types

Made to fit a broad range of 48-pitch applications, this pinion works for on-road and light off-road rigs without chassis rework. It is a good fit for hobbyists wanting quick gear changes and consistent engagement.

What shaft sizes will this pinion accept?

Check your motor specifications for compatible shaft diameters; the pinion is intended for typical hobby motor shafts used with 48-pitch gears. Measure before fitting to ensure correct seating.

Should I use threadlocker on the set screw?

A drop of mild threadlocker can help prevent the set screw loosening during use, but allow for future removal. Secure the pinion correctly and recheck after a short run.

How often should I inspect the pinion?

Inspect the pinion after any heavy impact and periodically during routine maintenance. Look for burrs, tooth rounding, or looseness at the set screw and replace if wear is evident.

Can this pinion be used on competitive race cars?

Many racers use 7075 aluminium pinions for a good strength-to-weight balance. Consider your powertrain and test changes carefully to maintain reliable performance under race conditions.

Any tips for achieving correct gear mesh?

Use a thin paper or a dedicated mesh gauge to set initial clearance, then run the motor briefly and recheck. Proper mesh avoids premature wear and noisy engagement.
