Tamiya M1025 Hummer Front Gear Box Aluminium Upgrade HM1012 by GPM  [HM1012]

Lightweight aluminium front gearbox for M1025

This aluminium front gear box is supplied as one set for the Tamiya M1025 Hummer platform and is identified as model HM1012. It is intended for scale RC drivetrain replacement and replicates the front assembly's role.

Designed as a metal alternative to the original part, the aluminium unit is suited for front gear box duties. Use it when replacing a damaged unit on M1025 Hummer or TA-01/TA-02 chassis; it mounts to the same front gearbox locations and uses existing fasteners.

When fitting, treat the component as a like-for-like swap: check gear engagement and mesh, inspect drive shaft coupling, and rotate the assembly by hand to confirm smooth movement before running. It is useful for regular maintenance and setup work on the front drivetrain.

HM1012 provides a sturdy aluminium front gear box option for M1025 Hummer owners carrying out repairs or routine servicing; always verify fit and clearance prior to final installation.
