Tamiya M1025 Hummer Front Gearbox Joint HM1041SF Steel Part by GPM  [HM1041SF]

This steel front gearbox joint is supplied as one piece and replaces the front joint inside the Tamiya M1025 Hummer scale gearbox. It is used where the original plastic component can wear or deform.

Design and fitment: made as an aftermarket substitute for the M1025 Hummer front gearbox joint, the component carries drive from the gearbox to the front wheels in scale RC applications. It is not intended for real vehicle use.

Fitting notes: installation involves gearbox strip-down to remove the existing joint and refit the steel unit. Use basic tools, set gear mesh correctly and inspect bearings to avoid introducing drivetrain bind.

Tuning impact: fitting a steel joint reduces flex under load and can improve repeatability in front-end response during setup changes. Monitor mating parts and rotating clearances after installation to ensure reliable operation.
