This document covers the procedure for mounting an Airmaster sensor-brush assembly to a Jabiru 2200 or 3300 engine
A conventional bracket is mounted to the engine crankcase using spacers and bolts. This applies for standard Jabiru flanges (AR-J0), as well as 2-inch extended Jabiru flanges (AR-J2.0).
It is recommended that installers mount the propeller hub to the engine flange and attach the sensor-brush assembly to its dedicated mounting bracket/cover plate before proceeding.
