This document covers the procedure for mounting an Airmaster sensor-brush assembly to a UL-Power engine.
Airmaster offers a range of mounting bracket solutions designed for UL-Power engines, accommodating engine flanges that feature either of the following propeller bolt patterns:
• Standard Rotax bolt pattern (4-inch PCD)
• SAE-1 bolt pattern (4.375-inch PCD)
• SAE-2 bolt pattern (4.75-inch).
These brackets are available in four lengths:
• 35mm
• 55mm (standard)
• 90mm
• 110mm
The installation procedure is consistent across all variants.
It is recommended that installers mount the hub to the engine flange beforehand and attach the sensor-brush assembly to its extension bracket before proceeding.
