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

Replacement 19T pinion for Mini-Z AWD

The MZA019T pinion is an alloy motor gear specified for use on Kyosho Mini-Z AWD models. It replaces the motor pinion to refresh worn teeth and offers a simple option for altering gear ratio for different running styles.

Delivered as a single unit, the pinion includes the screw required to mount it to the motor shaft. The chosen alloy provides a compromise between durability and dimensional accuracy to keep tooth engagement consistent.

Fitting guidance and setup

• Disassembly: follow Mini-Z AWD motor access procedures to remove the old pinion safely.
• Mounting: locate the pinion on the motor shaft, set correct mesh with the spur, then secure using the included screw without excessive torque.
• Mesh check: rotate the drivetrain by hand to confirm smooth engagement and correct backlash prior to powering up the model.
• Tuning role: a 19T pinion adjusts the final drive ratio slightly, offering a small tradeoff between acceleration and top speed.
• Maintenance: inspect the gear and fixing screw during routine checks and replace the pinion if any wear or play is detected.
