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

Alloy pinion for Mini-Z AWD

The MZA019T alloy pinion is an RC-scale motor gear made for Kyosho Mini-Z AWD cars. It replaces worn motor pinions and lets hobbyists adjust gearing to change acceleration and top speed on compact Mini-Z drivetrains.

The part is supplied as a single-piece unit and includes the mounting screw needed to fix the gear to the motor shaft. The alloy construction is chosen to balance wear resistance and dimensional stability for reliable gear mesh.

Fitting and tuning guidance

• Disassembly: follow standard Mini-Z AWD service steps to access the motor before removing the existing pinion.
• Mounting: slide the pinion onto the motor shaft, align tooth mesh with the spur gear, and tighten the supplied screw carefully to avoid shaft damage.
• Mesh check: hand-rotate the drivetrain to confirm smooth mesh and correct engagement before applying power to prevent binding.
• Tuning role: moving to a 19T pinion shifts the final drive ratio slightly, useful for fine tuning sprint response versus top speed.
• Maintenance: inspect tooth faces and screw tightness periodically and replace the pinion if any wear or looseness appears.
