Tamiya M1025 Hummer Rear Gearbox Joint for TA-01/TA-02 HM1041SR by GPM  [HM1041SR]

Heavy-duty steel rear gearbox joint for M1025 Hummer

This steel rear gear box joint is made for the Tamiya M1025 Hummer platform and supplied as HM1041SR. It is offered as 1 pcs and intended as an aftermarket RC-scale replacement to swap into the rear gearbox on compatible TA-01 and TA-02 style chassis.

The metal joint provides a stronger alternative to the stock plastic part, giving a firmer connection in the rear drivetrain for durability or tuning builds. Fit this part into the rear gearbox assembly using the existing mounting points on your chassis and verify proper seating before final assembly.

During installation check gear mesh and shaft alignment, inspect bearings and gears for wear, and ensure smooth rotation on the bench before testing. Follow standard RC maintenance practice when tightening fasteners and running the model.
