19T second spur designed for MTX-5

This Arrowmax AM-MTX-T2717 2nd gear is supplied as a 19-tooth replacement intended for MUGEN MTX-5 transmissions. Manufactured from 7075 hard aluminium, it is specified for hobbyists seeking a long-wearing aftermarket spur for scale racing gear trains.

As the intermediate spur, correct tooth engagement and uniform mesh are important for quiet, efficient drivetrain operation. Fit carefully, checking motor pinion alignment, ensuring bearings sit correctly, and adjusting backlash to the recommended MTX-5 clearance.

The 7075 hard aluminium construction balances wear resistance with precision machining for reliable mesh under load. Lightly grease gear contact surfaces, inspect for any burrs before assembly, and avoid excessive bearing preload to maintain gearbox reliability.

Compatibility

  • Mugen MTX
  • MTX-5

Do I need special tools to fit this into an MTX-5?

Basic RC workshop tools are sufficient, but use proper bearing presses and check mesh with a gear gauge or by hand to ensure correct engagement in the MTX-5 gearbox.

Is aluminium stronger than standard spur materials?

7075 aluminium offers higher strength and wear resistance compared with common softer alloys, helping maintain tooth shape under higher loads seen in competitive running.

How often should I inspect the gear?

Check the gear periodically after heavy sessions for wear and burrs, re-grease contact surfaces as needed, and reconfirm backlash if you change pinion size or motor position.
