Kyosho Mini-Z AWD Copper Second Servo Gear MZA622T by GPM  [MZA622T]

Mini-Z AWD copper second gear for servo train

This is a replacement second servo gear intended for Kyosho Mini-Z AWD use, identified as part MZA622T. Manufactured in copper, it is positioned in the servo reduction stage where it meshes with neighbouring pinions and the spur, offering metal-on-metal contact for improved wear characteristics.

Fitment tips: remove the servo to inspect the gear stack before fitting, align splines and set a correct mesh with the mating pinion, then confirm endplay after assembly. Copper gears can behave differently to plastic originals, so verify clearance under minimal load and manually turn the drivetrain to check for smooth engagement.

Setup advice: choose this copper second gear when you need better wear resistance and consistent tooth engagement in high-run or tightly geared Mini-Z AWD builds. Keep lubrication sparing and follow standard micro-servo care to protect gear life.
