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

Precision alloy pinion for Mini-Z AWD applications

The MZA019T is a CNC-friendly alloy motor pinion crafted for Kyosho Mini-Z AWD platforms. It functions as a direct motor pinion replacement to address wear and to provide a controlled method for adjusting the drive ratio on compact AWD chassis.

Supplied as a single-piece item with the necessary mounting screw, the pinion is manufactured to maintain correct tooth profile and runout tolerance for stable mesh under typical RC running conditions.

Service and setup recommendations

• Disassembly: remove bodywork and follow standard motor access procedures to expose the existing pinion before removal.
• Mounting: position the pinion concentrically on the motor shaft, verify uniform tooth contact with the spur gear, then secure with the supplied screw using light torque to avoid shaft deformation.
• Mesh verification: perform a manual rotation test to confirm smooth engagement and acceptable backlash prior to dynamic testing.
• Tuning considerations: selecting a 19T pinion will shift final drive ratio marginally, suitable for controlled tuning without major drivetrain overhauls.
• Inspection: regularly check for profile wear, burrs, and screw retention; replace components when wear exceeds service limits.
