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

Compact alloy pinion for Mini-Z AWD

MZA019T is an alloy motor gear made for Kyosho Mini-Z AWD cars and is intended as a replacement motor pinion. It helps restore worn teeth and gives a straightforward way to alter gearing for different performance preferences.

The pinion is provided as a single-piece unit and comes with the mounting screw needed to fasten it to the motor shaft. Alloy material aims to deliver good wear life while retaining accurate tooth form for reliable mesh.

Quick installation notes

• Disassembly: remove necessary bodywork and follow Mini-Z AWD motor access procedures before extracting the old pinion.
• Mounting: press the pinion onto the motor shaft, ensure the teeth align with the spur gear, then secure with the supplied screw taking care not to overtighten.
• Mesh check: manually spin the drivetrain to verify smooth engagement and correct backlash before running the car.
• Tuning role: a 19T unit adjusts the drive ratio marginally, a handy change for balancing acceleration and top speed.
• Maintenance: monitor for chipped teeth or a loose screw and replace when performance degrades.
