With the help from this group I recently purchased a well-used and abused 1981 Case 648. I would have preferred something in better shape, but I know how hard it is to find one and I think I paid a fair price considering the condition.
The good -
Runs and operates well other than needing banana plate repairs/tightening
The bad -
Everything else (just kidding-most everything else)
rotten muffler
weak drive
missing fenders/dash panel/seat support/headlights/drawbar/etc
some hydraulic leaks
needs bucket wear strip
Basis the features of this machine I suspected it was a 648 backhoe model, and someone had taken off the backhoe, fenders, etc. But after more closely looking I am now thinking this was a donor machine for someone to create a backhoe machine out of another Case loader.
I could sure use some help from the group in understanding what I bought and deciding how much $ into getting it back as close to original as possible. I have at least an understanding of what I bought.

It has the flotation tires and what I thought was the backhoe subframe, but it is actually a hand-made subframe for the weight box to be chained to. The fenders, seat support and drawbar are missing, and the heavy duty rear housing is missing. Looking at the rear housing from underneath I see it it orange/red color and not yellow, indicating it came from another machine.
Questions:
Is there any way to identify the rear to see if it is correct for this machine? I am worried this came from the wrong machine.
I have 3 hard hydraulic lines on the right side, two are hosed together and the other left open with check valve dripping. Can this line be capped?
I think I can find a rear seat support, fenders and drawbar for a guy on ebay for a 646, which should fit. Do I need anythign else to properly mount the weight box after removing the homemade subframe?
Any other noticeable parts I am missing?
Is there a generic gas cap available that fits these - the plastic gas cap is leaking

Also, I am getting a hydraulic leak where the line goes into the oil filter. It does not have any teflon tape on the threads, but they are tight. About 1 drop/10 seconds so I thought I could just loosen and add teflon tape- is this OK?
Thanks in advance. I have been working with Brian to order the Ingersoll parts like the muffler, but before I do I just want to make sure I have my full shopping list and that the rear is OK.
Thanks
Mark
