I finally have a little free time so here is an update. This past January I purchased a John Deere 440ID with the Model 71 Loader and Model 52 Backhoe. The serial number plate is missing so the best I can guess is that it's around a 1960. This is based on a little research and some details found on Johnny Popper. It's a 5 speed but the clutch is bad. It had a broken fitting and some bad hydraulic hoses on the loader and we lost most of the fluid getting it loaded on the trailer. It's heavy, no kidding. We needed it a little farther forward so it was a slow ride home. Anything over 25 or so MPH had the tail of the truck swaying. Needed a little more tongue weight.
Progress so far...
I added in some fluid recently and dug a hole with the backhoe. I added 43 Hydraulic oil since I new it was an old beast and since I live in Florida, cold is not an issue. This was before I got the manual which says to just use regular oil in case anyone is wondering. I recently bought the manual for the backhoe so if you have any questions please feel free to reach out.
It worked well and was really fun. It has a bad cylinder on the crowd. Bucket and boom are really strong. Right stabilizer leaks bad and the valve leaks so I am guessing there will some seals and rebuilds to get all that cleaned up.
Loader was getting air in the system but no leaks as I worked out the air. I suspect the filter in the reservoir is pretty dirty and it's only drawing fluid off the top.
I changed the oil and tracked down a wix filter. I found these listed but the message board has some comments addressing the fit for some:
JD 440 ICD
Fuel filter: Wix 3513
Oil filter: Wix 51100 (GM 1100)

Motor sounds great, it cold starts hard though. Once it's warm it fires right up. Its the GM 2-53 2 cycle Detroit Diesel. 2 Stroke with a super-charger has a very unique sound I will tell you.
Clutch is non-existent. I have to move it around with the directional-reverser. For anyone interested, I have to put it in the reverse position and then put it in reverse to go forward and 1st gear to back up. I think the clutches in there are shot too so I am planning a rebuilt and tranny overhaul (where needed) once I have the backhoe and loader off.
Brakes are bad. I can't tell is something is wrong mechanically since one is stuck and the other just doesn't seem to slow this beast down much. They are easy to get to so I will just check them out and probably just order the pads when I order the clutches.
That's all for now. The wife and I just had a baby so this is on hold for a little bit but I am anxious.
