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

Second-stage housing for MTX4 gearbox

This 2nd gear housing is an RC replacement component for the Mugen Seiki MTX4 chassis, supplied as part number MTX3-017. It forms the enclosure for the second-stage spur and its bearings inside the MTX4 gearbox and is intended for routine service, part replacement, or a full gearbox rebuild on the MTX4.

Compatibility is limited to the MTX4 gearbox layout, so confirm your chassis before ordering. When fitting the housing, restore the original gear mesh and bearing preload settings to avoid uneven wear. Check spur teeth and bearing condition while the box is open and replace any worn parts during the service.

Select this housing when you need to restore correct second-stage gear alignment and clearances during MTX4 gearbox maintenance or after damage.
