Hey all,
Looking for some guidance. Recently picked up a 1985 Case 1835b gas engine skidsteer with 3300 hours and has been sitting for the last 9 years. It was used only 50 hours in the last 20 years. It seemed to start and run fine when I looked at it. Once I get it home it proceeds to shut off randomly. Sometimes after 5-10minutes maybe 15, other times after 1 or 2 minutes. When its running it runs good and is strong. Just shuts off on its own frequently. I have looked through a number of things but I am at the point of needing some extra ideas. I have replaced the engine oil and filter as I was getting a low oil pressure light on the cluster. This is resolved. I have also verified the fuel shutoff solenoid is working, at least with the key on/off i can hear/feel it clicking. It has no problem starting up. From what I understand is that there may be a second coil to hold it open while running, but I don't now how to verify that. I was going to just try to remove the solenoid, and plug the hole and see if that helps and it stays running. It has a Zenith B75-22 solenoid in it with one wire. Don't know if that is oem or not.
I have also cleaned any corrosion from all of the sensor connections for the hydraulics, air , and oil....
Like i mentioned when it runs it runs great, moves great, lifts strong and quick, doesn't act rich or lean or starving for fuel. Doesn't really sound like there is intermittent spark or sputtering, sounds pretty smooth as far as I can tell. Just shuts off. Anyway just thought I'd see if anyone here had some thoughts they could share. Has some minor hydraulic leaking from bucket cylinders and what seems to be oil leaking from the outer valve guide tubes on the cylinder head. Otherwise it seems like a clean machine.
Thanks in advance for anything you can offer.
Jay
