Aluminum motor mount for MR-04/LM
This Kyosho MZW714-LM aluminum motor mount is a dedicated replacement part for Mini-Z MR-04/LM chassis assemblies. It serves as the structural interface that secures the motor to the chassis, providing a firmer mounting point compared with typical stock plastic parts and helping maintain consistent motor position during setup and fine-tuning.
The mount is described as aluminum in the product name, so expect a metal part that replaces the original motor fixing. In practice this part is used to retain motor alignment, support the motor bearings and pinion engagement, and reduce flex where the stock mount is the limiting element. Because the design follows MR-04/LM mounting locations the part installs into the existing fixation points on that chassis family.
Installation overview at a component level: remove the body and existing motor mount, transfer or fit the motor to the new mount, and reattach using the chassis mounting points while checking motor-to-spur mesh and axial alignment. After initial fitment confirm that the motor rotates freely and that the mesh and bearing preload are correct before full assembly. Avoid over-tightening fasteners to prevent stress on the chassis threads.
For maintenance and tuning, the aluminum mount can assist in consistent motor placement when swapping motors or adjusting pinion size, which helps keep gear mesh and drivetrain behaviour repeatable across setup changes. Inspect mounting screws periodically for loosening and ensure electrical connections remain secure after reassembly.
Compatibility
Compatible with MR-04/LM chassis as indicated in the product name, intended for Mini-Z scale installations only.
Use this mount when a metal replacement for the MR-04/LM motor fixing is required for consistent motor positioning and repeated setup work on Mini-Z chassis.
