Removing the flywheel, ignition housing (with water pump), stator... to get the ignition housing ready to ship to Leading Edge Airfoils for a new pump seal. WARNING: I ain't no A&P. Watch at your own risk!
To the attention of Rotax aircraft engine users! This engine worked for 210 hours and fell apart during the flight in the air. The reason was oil starvation of one crankshaft journal. A preliminary inspection showed that the problem was from the very beginning and the connecting rod at least received lubrication from the crankcase. But it wasn't enough and the connecting rod with the bushing, having received a large gap, collapsed. From beginning of operation with a warm engine, when the speed was reduced to a minimum, the temperature and oil pressure began to rise. By adding speed, everything returned to normal.
Thanks for the video - the sprag clutch on my 912 needs replacing so I'll either have to do this or cross the local engineer's palm with a lot of silver. Very useful to know that puller tool is absolutely essential.
I bet 50 bucks the reason your pump was leaking is that the stainless bolt with copper washer was not in the hole with the journal running through it. Put it back in the right hole and change the copper washer was probably all you needed!
Really enjoy your helpful expose of the 912's aft end. While its all apart it might be a good time to consider inspecting/replacing the starter sprag clutch?
