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

Mini-Z AWD copper second servo gear

This is an RC-scale replacement second servo gear produced for Kyosho Mini-Z AWD applications, supplied by GPM under model MZA622T. The part is made from copper and intended to sit in the servo reduction train where the second gear meshes with adjacent pinions and spur components.

Installation notes: remove the servo and inspect the gear stack before fitting, confirm spline alignment and correct mesh with the mating pinion, and recheck endplay after reassembly. Copper gears will seat differently from plastic spares, so verify clearance under load and rotate the drivetrain by hand to confirm smooth engagement.

Tuning role: use this copper second gear when seeking improved wear resistance and stable tooth contact in frequently run or closely geared Mini-Z AWD setups. Keep lubrication light and use standard micro-servo maintenance practices to preserve gear life.
