  • Going to tackle the Lift
  • I have been away from the boards lately. Busy busy and getting nothing done. I am like Uncle Joe, I move kinda slow at times. Wonder how many will get the reference LOL.

    OK, to the point. I am going to tackle the lift on the tractor. I downloaded the post that I think Dave made. However, I might need some pointers on things. I am going to do this alone; as usual. The main idea is to remove the lift cylinder and check it; actually I have another one that looks good so I am thinking honing and using it. I got the seal kit in hand; with the O-ring replacement for the old piston rings. Actually, this lift was done a long time ago with the O-ring. I will inspect everything of course. One concern I have is the top cover; how heavy is that thing? Will I need to use a come-along or something to lift it since I will be lifting it myself. I find lifting a 50 lb bag of fertilizer a bit hard but can do it. If the cover is 100 lbs I probably won't be able to do it without using some rig.

    Also, just general pointers that others may have come across. The lift is to the point where I won't be able to lift implements come spring ploughing. The last time I used it I was thinking I was going to have to leave the turn plough in the field. I managed to get it up and headed to the house and forgo the work I was doing.

  • What am I missing here. Trying to read all of the information that you have been provided and I can't find any reference to a possible weak pressure relief valve. Did I miss it? Anyone?
    I think there are a lot of good ideas offered in this thread and I'm noting some that I might use on another tractor.
    I have the 1951 8N that my father bought in 1953 when I was 10. I'm 76. The pump has never been rebuilt. It works just fine. I did rebuild the upper hydraulics; cylinder and an NAA piston and seals. I also have the Jig and cam follower pins that Zane Sherman had made available years ago. The cam itself was worn vary badly and I had it built up and then dressed smooth.
    The three point no longer gets used. And, it has retired from hayrides. It's only duty anymore is for a fresh air ride around the yard or down the road to a neighbors for a cold one on a hot day.

  • Tim mentioned it in the procedure he wrote up. In fact, in that article he mentions changing out the pressure relief valve even if one thinks it is good.

  • Oops. Guess I have to read Tim's DETAILS closer. I have to agree with him on that.
    Hey, Tim, sorry.

  • Re: Going to tackle the Lift
  • Just read through Tim's (not Dave) detailed procedure on working on the lift. Seems daunting but I am sure I can do this. Tim, do I need someone to help when guiding the control lever back in position? Is that a two person job?

  • Re: Going to tackle the Lift
  • I recommend having a helper. I've done these by myself only because I had no choice. I will never do another system again without a helper. It is good practice for safety reasons too. I also highly recommend using all new parts -cylinder, piston, and a complete cleaning of the pump. A pump rebuild requires dropping it. Note the 8N cylinder has the scallop cast at the 7 O'Clock position -a must have for clearance. On the 9N/2N cylinder it's not required. You can get kits for about 4100. The I&T FO-4 Manual has the R&R procedure too.

  • Re: Going to tackle the Lift
  • OK guys, thanks for your help. If I understand correctly, I can probably disassemble myself but I should get some help with putting it back together. I might can persuade my brother to give me a hand on putting it back together; or maybe my brother-in-law. Understand what you mean Tim on reusing the old cylinder I have. What about the piston? Yes, this is a 1949 8N. The lift does leak down with a heavy implement attached; is that what you meant by the leak down test? It is also slow in raising the implement; it has gotten worst over the years. The heaviest implement I have is a two row; four set, disc harrow and it was getting where I had issues using it last year. The pump was rebuilt many years ago, maybe 18 years now. The tractor does not see constant use. I think an old lift cylinder was used that had scratches or something; I can't remember now. So that is why I am leaning towards it being the lift cylinder and not the pump. I will read though the document you linked to before starting.

  • Re: Going to tackle the Lift
  • Kimberly, I use a beam in the barn rafters with a chain fall hung from it. Also got a fixture that fastens to the seat bolts that allows the top cover to be picked up level in both directions; makes it easy to put back in too. Can't seem to be able to put a picture on here anymore though.

    Your going to need a heavy prybar to pop the cover loose to begin with.

  • I made a simple 90* bracket & bolt it to a seat bolt, then use an old block & tackle so I can swing it over to a cart to work on or move to the work bench. Also it raises/lowers slowly.

  • Re: Going to tackle the Lift
  • It is simply a fairly sturdy 1 1/4" metal strap (could be wider if wanted) 9" long w/a 1" hole in one end, a 90* bend at 3", & two 1/2" holes (to allow for mis-measuring) spaced 3 7/8" apart for the 2 seat bolts. My old block & tackle hook is about 3/4" so hooks easily into the 1" hole. When mounted w/the 1" hole in the front it tilted almost perfectly (by accident!) for lifting & replacing.

  • Re: Going to tackle the Lift
  • Thanks Lynn,

    Depending on material on hand mine may not look exactly like yours but with those dimensions I think it will work.

  • Sounds like a good idea! Wonder if that will work on my 860. I have to work on it this spring/summer.

  • Re: Going to tackle the Lift
  • Kimberly,

    I've never done this on a 8N. I did replace the top cover on my 2N last summer due to broken parts. The 8N should be slightly easier.

    You will definitely need a hoist of some type. I used a come-along. You need to rig a lifting harness so you can lift the cover fairly evenly. I used a chain around the lift arms with another short chain rigged to the front two mounting bolts. Obviously I lifted it slightly to get nuts on those bolts.

    Make sure your tractor is on a level surface. Mine tilted sideways which greatly complicated the procedure.

    Since I was working alone, I lifted the top and then drove the tractor out from under it. Backed my Jimmy in and laid it on the tail gate to work on it. Reversed the procedure to reinstall.

    It's not extremely hard but take your time.

    Good Luck,

    Jack

  • Re: Going to tackle the Lift
  • Don't need much of a lifting device. Used one of these myself, bought at HF several years ago.

  • Looks like it would work. Does it have any type of locking device?

  • Re: Going to tackle the Lift
  • El-cheapo that I used did not. I simply tied it off to whatever was handy.

  • Mine locks but I don't trust it so I tie it off anyway!

  • Re: Going to tackle the Lift
  • You have an 8N if I remember correctly. You also best get some help as that top cover is heavy. There are u-toob videos on how-to as well. The key is to get the control inserted correctly when cover is assembled. First thing is to perform the leak-down test to verify if the cylinder is worn and leaking. You don't want to nor need to hone anything. If cylinder proves to be failing, I highly suggest you invest in a new one and forget using an old used one. That's a lot of work to go thru only to have the used one also leak. I also suggest you inspect and replace the cam follower pin if worn badly. This (see LINK) may help some...
