The answer is in this photo, Barny. At
least part of it is. I have a collapsible lift that is really a life
saver (back too), I can lift the engine out and in the mounts with
little problem. Takes me about 5 minutes or less (once I have spent
several hours disconnecting everything and taking the oil pan
off.
I lift the engine off the aircraft, roll the
lifts two long stabilizing feet under the van. Prop the rear hatch with
a long push-broom handle and then put the engine in back of the passengers
seat, then pull out the feet from the lift, load the lift, feet, etc. in the
van along with the engine and take off.
Works well, if you have the "balance" beam you
can see hanging in the photo - just turn the handle until you have the
attitude you want from the load and push it into place.
