Kyosho Mini-Z AWD Alloy Motor Gear 19T with Screw by GPM MZA019T  [MZA019T]

Alloy motor gear for Mini-Z AWD

This GPM MZA019T gear is an RC-scale alloy motor gear intended for use with Kyosho Mini-Z AWD platforms. It replaces the motor pinion to restore worn teeth or to implement small changes to gearing for tuning motor response and top speed within Mini-Z setups.

The part ships as a single-piece set and includes the mounting screw required to secure the gear to the motor shaft. Material choice and tooth count are relevant to durability and mesh quality, and the alloy construction aims to provide a balance between wear resistance and dimensional stability.

Installation and tuning notes

• Disassembly: access the motor by following standard Mini-Z AWD teardown steps before removing the old motor gear.
• Mounting: fit the gear onto the motor shaft, align teeth for proper mesh with the spur gear, and secure using the supplied screw; avoid over-tightening to prevent shaft damage.
• Mesh check: maintain correct pinion-to-spur mesh and verify rotation by hand before powering the car to prevent binding or premature wear.
• Tuning role: changing to a 19T pinion alters final gear ratio slightly, useful for fine tuning acceleration versus top speed on Mini-Z AWD layouts.
• Maintenance: inspect teeth and mounting screw regularly, and replace if signs of wear or loosening appear.
