Kyosho Mini-Z AWD Motor Pinion 19T Alloy Upgrade - MZA019T by GPM  [MZA019T]

19T alloy motor pinion for Mini-Z AWD

The MZA019T pinion is an alloy motor gear designed for Kyosho Mini-Z AWD chassis. It serves as a direct replacement for worn pinions and allows drivers to make small changes to gearing for different track conditions.

This item ships as a single component and includes the small mounting screw required to secure the pinion to the motor shaft. The alloy offers a mix of toughness and dimensional accuracy to keep gear mesh consistent under normal running loads.

Installation tips

• Disassembly: remove the body and follow Mini-Z AWD teardown steps to reach the motor before removing the old pinion.
• Mounting: position the pinion on the motor shaft, check tooth alignment with the spur, and fasten the supplied screw without over-torquing.
• Mesh check: rotate the assembly by hand after fitting to ensure there is no binding and that the mesh is even across the tooth profile.
• Tuning role: installing a 19T changes the ratio slightly, handy for trimming low-end punch versus top speed.
• Maintenance: keep an eye on tooth wear and screw security, replacing components as needed to avoid drivetrain issues.
