My bro has a 2294 Case International. The PTO stopped working, (turns with no load on it only) and it would only drive forward in the #1 powershift range. The next time I got on the tractor it shifted correctly, then the next time it didn't. (Confusing I Know) PTO still didn't work so I took the PTO actuating valve off and cleaned it, added another shim to the spring, (PSI was little Low) I put it back on, the pressure improved. A day or later, gauge still in the port,I totally lost my pressure, nothing. They do not make the pto valve parts anymore. Has anybody had one of these situations with these tractors? This tractor has a cummins engine in it, cab, 4wd.
