Hi I am working on a 630 caseomatic. As I understand it we should have 140 lbs pressure. We only have 40. When the clutch is depressed it goes to 0. Any suggestions? Is there a pressure valve stuck or a pump problem?
Thanks
 
It sounds like a faulty relief valve, or pump. They are mounted on the bottom of the cover with all the valve bodies on it. You will have to remove the fuel tank to remove the whole cover assy. The pressure should drop to zero, when clutch is pushed.
Befor going this rout, make sure the clutch pedal spring is pullind the pedal completely and valve spool is bottoming out.
As said by other poster, join us down on the Case DB forum below, for indepth details.
