Hi All,
My 64 4000 developed a leak on the pressure side tube of the control valve. I have unscrewed the tube and examined it to see if it was broken or cracked; it is not. The nut was secured well and required a bit of force to loosen the nut. The flared end of the tube did not appear to be crushed our mishapened. I don t see that there was any type of o-ring needed, based on this diagram: https://partstore.agriculture.newholland.com/us/parts-search.html#epc::mr60169ar258649
When the tractor is running, fluid flows from the pressure side. It does not spurt. This of course means that the reservoir is empty now too. I still have plenty of Multi G 134 left to refill it with so I at least I don t let it run dry. Only the best for my driveway...
On a separate note, water appears to be getting into the system. This tractor has a roller vane pump. The reservoir lid is secured with the clamp and screw. The gasket is new.
I am immediately concernd with the leak from control valve, any thoughts and/or suggestions about the cause or potential fix, are greatly appreciated.
