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

Precision aluminium front gearbox for M1025

This aluminium front gear box is provided as a replacement set for Tamiya M1025 Hummer builds and is sold under model HM1012. It is intended for RC-scale front drivetrain use and mirrors the original assembly's purpose.

The component is an aluminium housing suited to front gear box tasks. Use it when you want a metal replacement for the stock unit or when renewing a damaged front gear box on compatible M1025 Hummer and TA-01/TA-02 vehicles. It installs to the existing front gearbox mounting points and uses the standard fixings.

During rebuild and setup treat it as a direct replacement: verify gear mesh and alignment while assembling, check drive shaft engagement, and hand-rotate the assembly to confirm smooth operation before powering the model. It supports routine maintenance and chassis tuning where a front gearbox is required.

HM1012 is a direct aluminium replacement for M1025 Hummer front drivetrain maintenance and setup; confirm clearances and fit before finalising installation.
