Technical motor mount for MR-02 (MM) chassis

Part KZ-01/BU/WO is an aluminium motor mount assembly developed for the Mini-Z MR-02 (MM) platform. The assembly integrates a machined aluminium bracket with a bonded graphite plate to increase stiffness in the motor mounting area while maintaining the OEM gearbox footprint.

From a setup perspective the mount creates a stable datum for motor location, reducing variations in pinion to spur mesh when adjusting gear spacing or swapping motors. The graphite element is selected to limit local deformation at the fastener points, improving repeatability under lateral and acceleration loads commonly seen in 1:27 to 1:28 scale operation.

Installation notes for tuners: the unit locates on the MR-02 (MM) motor area and utilises the stock hole pattern. Expect drop-in alignment in most chassis, but confirm screw engagement, torque spec, and mesh clearance after installation. Regular inspection of fasteners and gear wear is recommended following initial track runs.

What material and construction details matter?

The aluminium bracket provides a rigid base while the graphite plate reduces local compliance; this combination targets dimensional stability at the motor-to-chassis interface.

How does this affect gear mesh repeatability?

By minimising flex where the motor is clamped, pinion engagement with the spur becomes more consistent, which helps maintain intended mesh settings across runs.

Recommended checks after fitting?

Verify correct motor mesh, confirm screw torque and that no bodywork contacts the motor assembly. Inspect after the first runs for any loosening or wear at the mounting points.
