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

Second-stage copper servo gear for Mini-Z AWD

This replacement second servo gear is made for Kyosho Mini-Z AWD applications and supplied as part number MZA622T. The gear is formed from copper to sit in the servo reduction train where the second-stage gear engages adjacent pinions and spur components, providing a durable metal contact surface.

Installation guidance: remove the servo and inspect the existing gear stack prior to fitting, confirm spline alignment and set an appropriate mesh with the mating pinion, then recheck endplay during reassembly. Copper gears seat and wear differently from plastic originals, so verify clearance under light load and rotate the drivetrain by hand to ensure smooth engagement.

Tuning notes: fit the copper second gear when you want improved wear resistance and steadier tooth contact on frequently run or closely geared Mini-Z AWD setups. Use light micro-gear lubrication and follow standard micro-servo maintenance routines to prolong service life.
