Side Rail Engine Mount
Kitfox™ Model Ill Builders with Rotax 582LC engine
Denney Aerocraft Company
an engineer for Bombardier-Rotax GMBH approved the new style Side Rail
Engine Mount we designed for the Rotax 582LC. He recommended that we
emphasize the following points:
The Side Rail Mount must be used only with the Rotax 582LC engine
with the Type C gearbox with the 3 to 1 ratio. It must not be used on
engines equipped with gearboxes with ratios of 3.47 or 4.0 to 1. To date
Denney Aerocraft has only supplied the type C in 3 to 1 ratio.
One hexagonal screw M8 x 90, Rotax part # 440 366 must be
shortened about 5mm or replaced by a screw of 85mm length.
This shorter screw must be used only in the position shown by
All other attachment screws part # 440 366 must remain the
original 90mm length.
Use one of the 8mm x 16mm screws supplied by Denney Aerocraft at
this attachment point. You must use a screw with an active working
length inside the upper aluminum crankcase housing of 16mm.
