Engine mount part five!

I then swung my hanging straps around 90 degrees and pulled the fuse up close to the engine.  This allowed me to align the engine perfectly and get the bolts and isolators installed.  I did put a little bit of silicone lube on the isolators to get them to slide together easily.  I installed the bottom bolts first.


Then the top ones.  It is a tight fit on the top.  

I then torqued down the bolts per the KAI's.
Looks great hanging on the plane.  It is amazing how compact this engine is!

Engine mount part four!

You will need a long ball end 8mm allen key to get to the top left mount bolt.  You have to look up the torque spec in the Rotax maintenance manual.  That manual also calls out that the bolts must have medium loctite when installed.


Then you are asked to reconnect the lower coolant lines.

Once that is done there is a procedure to match drill up to full size the lower engine mount bolt holes.  Easy peasy just follow the KAI's.
