I've done something similar myself with the help of 4 others. I had this old shitter ke20 and wanted to pull the motor out of it with the least hassle.
We rolled it on its' side, with the intention of removing the gearbox, and to put it back on its' wheels to lift the motor out of the engine bay.... didn't quite work out to plan though. LOL.
On its' side we removed the tailshaft, gearbox xmember, bellhousing bolts and disconnected the other crap. The gearbox didn't want to come out easily so I shook the shit out of it to have the gearbox come out in my hands. At the same time the engine mounts broke and the motor fell out the otherside and landed on the ground. :wink:
Time from start to finish for motor and gearbox removal was 10 minutes. :y:
