take it easy..
The UM 4 is not the same height as a standard dishwasher. Without the extra brackets on the frame, it would be about 6-8 inches lower than standard. Also, if you dismantle it, the mounting brackets may break off and then you will be in trouble as they were not stainless like the tank.
If you can manage it and have a car with a decent sized trunk or hatchback or pickup, you can probably drive down and get it. Give that some thought but either way, the unit will fit on a small skid and I am sure there will be a crating company that can handle it. Maybe even UPS or FedEx freight can take it.
They do handle over sized or over standard weight items as common carriers.
As far as spare parts go, you are taking on a totally obsolete machine at this point. Just about everything for it is gone now.
Any parts from the 11 thru 14 series will work like the motor, seal, washarm and the door interlock switch and actuator.
Timers and drain valves are long gone. But again your domestic spares if they are in good shape will carry you thru.
What a pleasure to use a machine with a 3 minute cycle!
And remember..The UM4 was strictly GRAVITY drain. So make sure you can work with that. And if you are mounting it under a standard ht counter, you may need to build a base for it or use long bolts to raise it up. See if you can get a picture of it and send it to me or post it here and I can tell what it came set up as.
