UPDATE ON THE MACHINE
Well, I got hold of my old boss and we negotiated a price based on my further research and acceptance of the machine... It would have been a part cash, part work off deal, so it would have been pretty sweet.
I looked it over much more carefully this time... There are alot of useful items on it--multispool valves, hydraulic motors--appear to be Sundstrands, the tires are about 75% remaining on 26x12-12s bar lug... hole spacing appears to be 5 on 4.5:. The axles themselves look like Dana 27s, or maybe 44s.
The engine is a Wisconsin VG4D if I read it correctly. It's missing the RH cylinder head, and the bores are rusty, but there may still be usable parts. It's Terex green in color, so I knew it wasn't original, but it looks like it may not be the correct engine for the machine also, as they had to cut parts of the frame and hood to install it.
As I mentioned it's missing pumps that drive off the flywheel side of the engine.
The machine seems to have two hydraulic reservoirs. 1 is under the seat and is for the backhoe, the other is under the battery near the front of the machine (trencher chain side). I didn't see a fuel tank, but there's a big open space at the front, so I suspect that's where it went.
I'm not sure what the second reservoir is for since the trencher is chain-driven, with the sprocket attached to a shaft. At the other end of the shaft is a clutch and a large poly V-velt pulley that is turned by the engine.
The entire backhoe, though too heavy for a GT at 900 lbs, may work on a Compact Tractor. It is pinned to the frame of the machine, but the operator's position and valves are bolted to the frame itself so some modification would be required.
Anyway, it is missing the pumps for the backhoe and the steering system. I probably could use something else, but overall, it is a MUCH bigger project than I thought. I found you can access the parts book through Case Construction online. Almost all of the major components--hydraulics, etc. are no longer available from Case.
So, I decided not to pursue it. If I find a CUT, I may buy the backhoe, but we'll have to see about that.
BTW, here's some of the specs for the machine:
- Wisconsin DH40 gas engine
- SD100 backhoe
- 48" trencher dig depth
- 8" trencher dig width
- 88" backhoe dig depth
- 81" backhoe dump height
- 18"W backhoe bucket
- 115" overall backhoe reach
- 54" wheelbase
- 26x12 tires, 4 ply
- Machine weight without backhoe: 3,000 lbs
- SD100 Backhoe Weight: 900 lbs.
