HPI Baja Precision Spur Gear Adaptor BJ115 Alloy by GPM  [BJ115]

Precision spur adaptor for HPI Baja drivetrains

This machined alloy spur gear adaptor is a replacement component intended for HPI Baja platforms. It provides the mating surface between the spur gear and gearbox or motor mount, maintaining axial alignment and consistent mounting geometry for the drive train.

Installation notes focus on seating accuracy and axial alignment: ensure the adaptor sits flush on the spur hub, secure with the original hardware, and verify pinion mesh and backlash once installed. The component is supplied as a single pcs unit to replace worn adaptors while preserving existing motor and spur gear specifications.

Use BJ115 to reinstate correct spur mounting and preserve drivetrain geometry on HPI Baja platforms; inspect mesh after fitment for optimal performance.
