    Default Case Trencher Tire Pressure

    I have a Case 25+4XP Trencher with a SD70 Backhoe. I dont have a manual, and I think it is going to be impossible to find one. In the mean time could someone tell me the what tire pressure the GoodYear 26 X 112.00 - 112NHS 4ply Terra Tires might use? There is no max tire pressure marked anywhere on the tire.

    Thanks J.J.
    I'm new to the trencher/backhoe myself. Spent the winter cleaning it up and painting it. She looks and runs like new. What is the word on your white powder engine problem? Is it a wisconsin engine?

    Haven't figured out the powder yet, but I am going to bypass the fuel pump for now and see if I can get it running. It is a Wisconsin VH4D, 28 HP. It will run on starter fluid, so that is a good sign. I know I am going to have to replace two large hyd hose on the big hyd motor on the left side. What kind of hyd fluid does your trencher use?

    Unbolted the fuel pump off the Wisconsin, to take pictures of that white powder stuff. Still have not figured out what it is. Here are some pictures.
    Looks like someone took the top off the fuel pump and poured some powdered laundry detergent in it.

    I am going to try and fire up the engine and see if it will run using gravity gas flow.

    My Case has a label on the fluid fill neck. It says to use hyd fluid or Automatic Tranny fluid. It looks red in color so I believe the guy I bought it from just used tranny fluid. I should be able to put it through a few tests soon, now that the weather is getting nice.

    I found out what that white powder looking stuff in the fuel pump was. They said it was a combination of old gas, water, and sitting in that aluminum bowl a long time, and the powder was the result of the chemical reaction. . A new fuel pump for the trencher is about $150. They said to just junk that fuel pump and get one of those electric fuel pump with about 1 to 3 lb of pressure, at a cost of $50. Going to install it next week and see if I can get it running.
