Reliable 48P 39T gearing solution

The Arrowmax AM-448039 is a dependable 48-pitch, 39-tooth pinion suited to hobby and club use where consistent mesh is important. Its geometry is intended to lower vibration and provide predictable engagement with matching spur gears.

Durability and wear considerations

When mesh is set correctly, the precise tooth form reduces localized stress on gear teeth, which can help prolong the life of both pinion and spur. Regular inspection after several runs will reveal any unusual wear patterns early.

Compatibility guidance

This pinion is designed for compatibility with standard 48P gear sets. Confirm shaft type and bore size before fitting and perform a controlled test run to verify smooth operation and correct mesh depth.

Do I need to change motor positioning when fitting this pinion?

Adjust motor position only to achieve the correct mesh; minimal movement is usually required if the shaft and bore are compatible.

How should I inspect the gear after break-in runs?

After initial runs, check for even wear across teeth and ensure no chips or heavy scoring appear; recheck mesh and set screws as part of routine maintenance.
