  • Hydraulic lube
  • My lift lever on my 51 was getting very hard to use so I decided that I would take the lever off the shaft and lube it. Had to use a puller to get it off and then I see that it had heavy rust further into the cover that I couldn't get to. So I took the seat off and then all the bolts. I pried the cover loose and found out how heavy that thing is. With it upside down on the bench I got the shaft out and cleaned it up. Inspected the piston and cylinder, went into town for new ones. Drained the sump, flushed it out good. Not much sludge. Put a new PTO seal and bushing in too. New relief valve. Getting ready to reassemble now and was wondering how all the little springs and levers under the cover get lubed?Do I give them a good coat of 90wt before I bolt the cover back on? My sticky lever is into me for about $200 so far, but it's good therapy for me! I wanted to take the lift arms off too for a good blasting and paint but they ain't budging.

  • The lever can freeze up from condensation.I have had to use a heat gun to thaw out the shaft.

  • I took my top cover to an implement dealer and his mechanic pressed the lift arm off. Only one was seized on mine.
    Not sure about the oiling on the linkage. What or however it happens, not much oil gets up there from what I could tell.
    If you have a hoist, that could help a lot putting the cover back on.

  • HHHMMM, a lot of work, should have checked here first. Why would the lever get hard to operate? Then have to use a puller to get it off...hope we're talking the same thing here...there are 4 bolts that secure the hydraulic pump to the top cover. You don't remove them until you have the cover off. There is no lube required so why are you wasting time and money? How did you manage to work on it without any manuals or prior knowledge of the system??? Best to get an I&T F-04 manual; an MPC; and Operator's Manual and read before it's too late. This may have helped:

  • The things in the compartment are "splash lubed". A manual is good but I hope you're having fun anyway.

  • Re: Hydraulic lube
  • Because the shaft, (part # 517), was rusted to the housing, (part #515). I don't see what you mean by 4 bolts holding the hydraulic pump to the top cover. Do you mean the cylinder? if so, then I didn't take it off till it was sitting on my bench. I have all the manuals and experience to work on this. As for wasting time and money, the only parts and gaskets I'm replacing are parts that are in need. The cylinder and piston were scored badly. The PTO shaft seal was leaking and the sleeve, (part #735), was grooved. As for being too late I'm not doing brain surgery here, it's a mechanical device. Now back to my question, how are all the springs and levers under the top cover lubed?

  • Re: Hydraulic lube
  • yes, meant to say 4 bolts secure the cylinder to the top cover...

    If you mean the valve chambers, again, the only lube comes from the system itself. There are no parts that require special lubrication or servicing. All 'the manuals' would've told you don't you think? I've never seen a frozen PTO Shift Lever but I guess some of you have. I suppose if a tractor was setting in a field for 50 years everything would be rusted up and the PTO shaft would not be my first priority...

  • Re: Hydraulic lube
  • We seem to have gotten off track here. All I wanted to know is do the parts that are under the lift cover, (#52 FO-4), such as the cam, #46, position control arm pin, #71 and all the other little levers and springs get any lubrication? I never said anything about a frozen PTO shaft. I haven't found anything in "the manuals" saying they do or don't. I have a lot of manuals and books. I subscribed to the N Newsletter starting back in the 90s and have the back issues. What my original problem was is that the shaft for the control lever, #57, was getting pretty close to being frozen to the quadrant, #56. I see no way to get lube to the shaft with out taking some of it apart. It has 2 bearing surfaces and one of them is inside the main housing.
