Pops,
I too have a 1910. When I bought it I was told the hydraulics didnt work...and they didnt. I learned how this tractor worked and then resolved it. All I needed was a new filter and fluid. I know you changed the fluid already. Have you checked the intake screen on the suction side at the transmisson. If you have no lift think like this.
1 No pressure out due to loss of pressure along the way by either open diverter, or leak etc.
2 If your output was plugged somewhere the plug would have to withstand 3200 psi. Not a likely cause. Plus you would hear the engine loading down at a low rpm while the full power of the pump bled off thru the overpressure relief valve.
3. Most likely cause is that the suction is blocked and your pump is starved.
Flowmeter will tell this if the flow is low. But you can just open the line and check the intake screen on the tube. Mine was missing unless it wasnt in the tube but instead the transmission and I didnt stick my finger into the transmission hole. This screen is your highest probability. Or you can be sucking air due to a leak in the suction side of the line. Same symptom....no pressure. Last you can have water in the system. When you changed your fluid did you open all 3 drain plugs? 1 on rear differential, 1 on transmission, 1 on front wheel drive take off where the shaft hooks to transmission. These are the lowest points and all 3 will hold water. I failed to do this the first go round then figured it out later when foaming continued. Is your oil getting white and foamy or just lightly white and not too bubbly foamy on the dipstick?
Now for the goodies. I have a complete service manual and operators manual. I can copy you the diagrams, trouble shooting tests and pressure test points and power steering pressure relief valve setting procedure. Also the info on the operation of the hydro valve for the lift.
Let me know and we can get in touch on the phone or something. If you need a cheap pressure guage that can go to 5000 psi I bought 2 at Harbor Freight for $12.00 each. They are even fluid filled for dampening. You could get one and use it to see the actual output and even leave it in at all times if you wanted.
Let me know.....
