Aluminum motor mounting for MR-04/LM chassis
This Kyosho MZW714-LM aluminum motor mount is a dedicated replacement part for Mini-Z MR-04/LM chassis assemblies. It acts as the rigid interface that secures the motor to the chassis, providing a firmer mounting point than stock plastic components and helping preserve motor position during setup and tuning.
The mount is specified as aluminum in the product name, so expect a metal item that replaces the original motor fixing. In use this component retains motor alignment, supports motor bearings and pinion engagement, and reduces flex where the stock mount can be the weak link. Because the geometry matches MR-04/LM mounting locations the part installs into the chassis using the existing fixation points.
Installation overview at a component level: remove the body and the original motor mount, attach or transfer the motor to the new mount, and secure it to the chassis while checking pinion-to-spur mesh and axial alignment. After fitment confirm that the motor spins freely and that mesh and bearing preload are correct before final assembly. Do not over-torque fasteners to avoid stressing chassis threads.
For routine maintenance and tuning, the aluminum mount helps keep motor placement repeatable when swapping motors or changing pinion sizes, which aids consistent gear mesh and drivetrain behavior across setups. Periodically check mounting screws for loosening and ensure electrical connections remain secure after reassembly.
Compatibility
Compatible with MR-04/LM chassis as stated in the product name, intended for Mini-Z scale installations only.
Choose this mount when a metal replacement for the MR-04/LM motor fixing is needed to maintain repeatable motor positioning and reliable setup work on Mini-Z chassis.
