Need help with a pre-Case Uni-Loader

[Frickyjim]

I picked up this old skid steer a couple years ago, I'm in the process of rebuilding it. As far as I can tell it was manufactured by the Universal Manufacturing Co of Hudson Iowa. This company was bought by Case in 1968 or 69. All the information I can find says they only built clutch style machines. As did Case for the first several years. Mine uses two Vickers variable speed hydros and is a factory built unit. It has a 37 horse Wisconsin that drives a splitter box to the two hydro's. The lift and tip bucket functions are tapped of the hydro's so there is no seperate pump.
You can see pictures on my webspace at http://mysite.verizon.net/respvksi/
Any info would be appriciated, also the chain cases are the hydraulic tanks so I am thinking about suction filters on both the hydro's any idea's on what size?

Don't the filters have numbers? You don't want them to be too fine as they will plug up too fast and can damage your pump due to lack of oil. I thought it was about 30 microns, but I'm not sure.
What is wrong with it that you are aware of?

Tazza,
It had numerous seal leaks and one of the hydro's was also leaking so I figured I may as well pull it all down and start from scratch. It had strainers in the suction lines that I know were not original, they just plumbed them in and left 'em hang. I would like to have the convenience of the spin on filters. I figure I would change them within the first 25 hours or less and regularly after the break-in period.

Spin on sure are easier, especially when the hydraulic system shares its oil with the drive chains its probably a good idea to have it so you can swap out the filters more regularly. Just don't go too small and it may also pay to have a sensor so you know when the filter is blocking up too much. Not sure where to get them but they would be available.
Keep us informed with your progress, looks quite interesting!
