It is as Pat describes, Liftall "belly" pump (not live, the clutch must be driving the transmission in any gear or neutral to work) it also has a the "Christmas Tree" valve on it. I cannot see the pressure connection for the valve. from the Liftall. It is usually from the Right hand elbow (shown in your pictuer with a brass plug) to the valve. Without the hose, the valve would be disconnected, thus the pressure would revert to the 3 output elbows on the tractor casting, the one mentioned, another on the other side toward the front of the casting, and one toward the rear of that that is a delay lift/Lower port. I would begin testing by seeing if the Christmas Tree is connected to the other side (can't see it in the photo). If it is it still needs a control rod to the Christmas Tree valve lever. If it is not, I would check the fluid level in the reservoir (cap with finger grips should be where the pipe with Union, elbow and apparent pipe plug) is located. The level of fluid in the res. should be 8 to 10 inches below the top of that union mating surface. (take the union apart to check level (not stock, or convenient at all. If there is fluid (Hytran, or 20wt non detergent engine oil), and the casting elbows (three) are plugged, then I would pull on the existing lever to see if the engine bogs down a little with some attendant noise. If so the pump is working (to some degree). If nothing at all changes, I would then check the drive coupling from the transmission countershaft, to the pump. A plate under the tractor behind the pump housing must be taken off to see this, (no fluid should be behind the plate, it is a dry location) Good luck. Jim
