Auper D6 Blue Gear Drive Bulkhead SAK-D6825/BU - Service Replacement by 3Racing  [SAK-D6825/BU]

Overview of the Auper D6 bulkhead

This gear drive bulkhead fits the Auper D6 platform as a like-for-like replacement. It forms the housing interface for the gearbox section that positions the gears and bearings, keeping alignment consistent under torque and during setup changes.

The part secures axle and bearing locations that determine backlash and mesh behavior. Before final assembly, transfer any spacers or bearings from the removed bulkhead and dry-fit components to verify alignment and prevent binding.

Fitment tips: remove gearbox bolts in sequence, move over bearings and shims, then clamp the new bulkhead in place while checking gear rotation. Progressively torque screws and verify smooth drivetrain movement.

Designed for RC hobby use on the Auper D6 chassis, this bulkhead restores the gearbox mounting and helps with tuning geartrain clearance and backlash.
