Upgrade for Auper D6 Spur Mount SAK-D6809D/BU - Blue Adaptor by 3Racing  [SAK-D6809D/BU]

Dedicated spur adaptor for the Auper D6 chassis

This adaptor is supplied as a replacement or hop-up component for the Auper D6 chassis. It interfaces the spur gear with the drivetrain hub, keeping the large gear positioned for correct mesh and rotation inside the transmission path.

The item is listed as 3Racing SAK-D6809D/BU and is finished in blue. In practice the adaptor provides alignment and secure seating for the spur gear, so confirm gear alignment and backlash after installation to ensure even meshing with the pinion gear.

Installation notes: install this adaptor in place of the existing spur mounting component on the Auper D6, verify concentricity with the motor pinion, and confirm the spur spins freely across the suspension travel range. Inspect nearby bearings and gearbox interfaces while reassembling to preserve drivetrain reliability.

Tuning guidance: small spur position changes affect mesh and noise—adjust in small increments while observing contact using thin paper or visual checks. This part is for RC-scale drivetrain use only.
