1964 Case G430 Gas Rockshaft hydraulic problem

If I keep the oil at the proper dipstick level, the rockshaft arms won't raise at all. If I overfill it, it raises very slowly and chatters a bit on the way up. Once it is overfilled so that it raises-when it lowers oil spews from the vent under the seat at the rock shaft position. This oil is very aerated/foamy. But once it is up it will hold all day. I replaced the piston cup seal and wiper because I originally thought that it was leaking by the piston seal to then leak out the vent. With brand new seal it is still leaking out the vent, but I now believe it is becuase of being overfilled. I am going to put a psi guage on it now and check pressure next. Anyone else ever have a similar problem?

 Where are you putting the hydraulic oil? in reply to Eric Stenberg, 08-06-2007 07:56:10  
Hydraulic oil (TCH) should ONLY be added to the torque tube reservoir (plug near the hand clutch lever) forward of the foot clutch. The rear end has a measuring rod on the fill plug (near the left side of the driver's seat) and its FULL mark is very near the bottom of that measuring rod. When the rear end (90W gear lube) is filled properly, there is no possible way for oil to come out of the rear end vent. If it's over filling with hydraulic oil, there has to be a crack in the rock shaft housing, scoured rock shaft cylinder, defective O-ring on the rock shaft cylinder end cap, piston seals are defective, or the rock shaft seal has been installed improperly. While there is a seal between the transmission and the rear end, the seal would have to be nearly gone to cause a problem. Even so, that seal would NOT cause the problem you are describing.

It can if he is overfilling it in the wrong place....I think he has a shot transmission/hydr. resevour seal.
