MTX4 2nd Gear Housing MTX3-017 for Mugen Seiki by 3Racing  [MTX3-017]

MTX4 second-stage gear housing

This 2nd gear housing is an RC spare designed for the Mugen Seiki MTX4 chassis and is identified by model MTX3-017. It encloses the second-stage spur gear and bearing stack in the MTX4 gearbox and is intended for standard maintenance, repairs, or gearbox rebuilds specific to that model.

The housing matches the MTX4 gearbox layout, so confirm compatibility with your chassis before ordering. During installation, restore original gear mesh and bearing preload values to avoid accelerated wear. Inspect the spur teeth and bearings when you open the gearbox and replace any parts that show damage.

Choose this housing to restore correct alignment and running clearance of the MTX4 second-stage gears during service or after impact damage.
