Farmall H lift-all system?

To reduce oil foaming the return oil needs to be returned below the level of the oil in the reservoir. If the flow is not too great it may be acceptable to allow the oil to return running down the inside wall of the reservoir. The Lift-All pump has about a 4 to 6 inch drop for the oil if returned to the fill pipe and will cause foaming.

This diagram will do the two way operation. Position the valve or valves securely where they are easy to reach. The level indicator is a dip stick in the top under the baker's hat cap. A plug goes into the side (down pointing) threads in the "T" at the bottom of the resivoir. This is not a live hydraulic system, the clutch must be out for it to operate. The lever (rod) controlling the Liftall must be pulled out and heald to keep the pump running. A fuel line hose clamp will work. The valves must be open center type, as shown. The ports on the left side connect to the same pressure. In this case they are plugged. The rear port can be made to delay lift and drop for trailing emplements if equipped with a restrictor delay valve. This is only used for single acting trailing or mounted equipment. I hope this helps. JimN

This is the diagram discussed above. It has a better bottom fed return. JimN

Here is a schematic for the liftall if you want power up and power down. You can email me at srukke@comcast.net if you want a scan of the owners manual and how it works. There are different ports on the system and one is a delayed port. I highly recommend that you plumb the return line into the bottom of the tank rather than the filler tube. The oil may foam up if plumbed to the filler. I put a tee where my drain plug was and plumbed the return in onmazingly the system uses 30w motor oil. You can use hydraulic oil but it is designed to use motor oil.
