Need Hydraulic Help on 35 Special

1) Checked fluid,the level was fine but I did notice it looked a little milky. I am wondering if water got into the case somehow and mixed with the oil and the water froze the pump and damaged it?

2) I noticed that when I disconnected the plow the three point would not got all the way down, so I moved it in the garage and turned the heat on and after about an hour it dropped down all the way. I am guessing it only moved about 3-4 inches but it still was hung up on somthing.

3) Now, I fire up the massey and try to move the plow up and down and nothing happens except I do hear a faint noise like a bubbling noise or somthing.

4) I shut off the engine and manually lift the three poit and there is no resistance what so ever, and I can go from stop to stop. It's dead. I did notice somthing. when I get somewhere in the middle of the travel of the three point, I can feel a metallic clicking noise, It is very faint but definitly repeatable.

5) This is my diagnosis>>>>>>> Maybe a relief valve is stuck open? Filter plugged? Broken parts$$$$$$?

Thanks Jim

(2) The lift arms will go lower if you use the draft control lever for the lowest position.

(3) Could be a plugged hydraulic filter. Does the PTO work OK? The same shaft drives the PTO and the hydraulic pump. Some 35s have engine and ground speed PTO, if the ground PTO works and engine doesn't, most likely the 2nd stage of the clutch is out of adjustment or shot.

(4) The 3 point has a one way cylinder that just pushes on a heavy duty ram, the click you hear is the ram as it falls out of a cup shape piston, the ram is long enough so it doesn't hurt anything and just goes back into the cup shape piston when you let the lift arms down again.
