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

Auper D6 gear drive bulkhead overview

This gear drive bulkhead is a direct replacement-style part for the Auper D6 platform. It acts as the mounting surface and housing interface for the gearbox gear drive section, keeping spur and pinion alignment stable under load and when you change setup.

The component's job is simple but critical: lock axle and bearing positions to control backlash and mesh. When fitting a new bulkhead, move any bearings or shims from the old unit and confirm fitment before final tightening to prevent binding or unwanted endplay.

Installation notes: undo gearbox fasteners in sequence, transfer bearings and spacers, then secure the replacement while checking gear mesh as you rotate the drivetrain. Tighten screws progressively and recheck rotation to ensure smooth operation.

Suitable for hobby-scale RC service use on the Auper D6 chassis, this bulkhead restores gearbox alignment and supports tuning of geartrain clearance.
