Jubilee/NAA three point lift adjustments

welcome back to the Kiva's Ridge homestead I'm Brian and today we're gonna take another look at the hydraulic three-point lift on this old Golden Jubilee tractor by far our most viewed video was why tried to rebuild this to stop the leak because the the implement would lift up and then drift down a little jerk back up drift down a little try putting the new piston in it and that didn't fix it so today we're going to tear this cover back off and we're going to do an adjustment on it now I did the same video about two weekends ago and realized when I was editing it that I did the adjustment procedure wrong so I'm gonna show some of the old footage of that video now showing the problem and where I found the leak and then we're gonna pull this cover off and redo the adjustment procedure correctly today and I'm gonna use my engine hoist to lift this off it's a it's a heavy son of a gun last time I just lifted it off by hand and it's it's pretty heavy so we'll use the hoist today to get it off of here so I'll play some footage here from before showing the problems and then we'll pick back up with this on the bench and doing the proper adjustment procedure so come along hello welcome to our channel here all the information I can find on the internet and on tractor forums and so forth says what you're supposed to do is remove your side cover this is where your PTO lever is normally attached you will lose a little bit of hydraulic fluid out of your bottom bolt so make sure you got a catch pan remove this side cover take a flashlight and look up inside while the tractors running and see if you can see any drips now unfortunately it's pretty impossible to get the camera up in there and show you but I do have a borescope camera that I put in there and here's what I found as we're looking up inside of there that shiny silver part right now is the piston and as you can see there's no fluid at all leaking from the piston so now we're going to turn the camera toward the front of the tractor there's the valve body and you just saw a drip come off the front of the valve I don't see any any leaks up there on the faceplate so now we're gonna move more toward the well the front of the tractor which is the other end of the valve body and you can see a pretty steady drip right there coming off that valve body so we're definitely going to have to look at the valve body and see if we can find where that leak is coming from on there check this out a little better I think you can see how it's drifting down and then dripping back up that's the problem we're trying to cure now the reason I put the Box blade on was I wanted to try looking inside there under a load cuz in the earlier video that we saw the drips coming off the valve body but I really couldn't determine where it was coming from so I thought maybe it was some weight on there and the tractor rpm up I'd be able to see and as you can see in this video that stream was just the drip in the front of the valve body so you know apologize for the shakiness of the camera but it was that's the borescope up in there in the front of the valve body and you can see that the the drip is a steady stream and it looks like it's coming out of some kind of a vent hole or something on the front of that valve body so once we get that off of there we can take a let better look at it and try and determine exactly where that's coming from well so you can somewhat make out on that internal camera video the oils leaking out right here out of this little cover and dripping down there so we'll pull this cover off show you what's under here [Applause] there's a spring under there so you got to watch for that and once that cover little thin cover plate comes off with the spring there's another plate here you pop off now originally there was a thin gasket under here which is not available anymore so I just put a little bit of gray silicone on it to try and seal it up and be honest with you I don't even know why there's a gasket there because there's really nothing that gets sealed by that plate there's a large plug here that has a shuttle valve inside of it there's a small plug down here that I believe has like a pressure yeah that's what the pressure release valve goes then there's a hole here that has the the shuttle in it tip you up a little bit you can press see it move back and forth this is what actually your your touch lever moves back and forth to set your height you can kind of see in the hole as it moves back and forth well I'm 99% sure that the leakage is coming out of this hole I think this spool valve is worn enough that it's bleeding fluid past the end of the valve and it's leaking out of here so unfortunately I don't know if any of those parts are still available or not as I've said before we're selling this tractor so I'm not going to try and track down internals on this and put put more money in it the tractor is completely usable as is it just jumps up and down a little bit so unfortunately this is the second video on the dropping three point on this tractor that we're actually not gonna fix that problem because like I said I'm not I'm not putting more money into this tractor when when we're selling it but that appears to be where it's leaking we know for sure by the video that the fluid is leaking out of here keep mind this is upside down right now and running running down this way so if if you have the same tractor and have that same jumpin three-point problem and you can put a camera in there and check that at least you kind of know what you might be looking at and then maybe maybe start looking for the spool valve and potentially that centerpiece so we'll put this cover back on and then we'll start the actual adjustment procedure the first step in the adjustment procedure is to remove the spring of the draft control so you want to turn your you're clevis off the end it says you can try breaking this loose when it's still on the tractor because it's hard to get off mine was never tight it was kind of loose like this all the time so it was no no problem for me to get it loose because it was already potentially quite loose so you want to unthread this and then remove your spring the position control to be properly set this has to be properly set first for the draft so we'll remove these bolts off the back and one thing it says is very important is this plate here check it for straightness mine does have a very slight bow to it but not very bad and say if this thing's dish too much you won't get a proper adjustment so once you get this apart kind of clean everything up a little bit I'm gonna go get my parts I bought a new new felt ring to go in here so let me grab that okay when you put this back together after you clean everything up when I took this apart the first time there was actually a layer of dirt between here and here that's how loose all this stuff was so install your piece there put the new felt ring on start the brackets tighten it up put your spring back on and clevis and what you want to do is tighten this up until there is no play left in the spring okay we're getting closer okay there's no sprit noose no play left in that spring and then you're supposed to tighten this one full term beyond that there's a half a turn and there is one turn so that is the first step in the adjustment procedure to get this cleaned up and get this draft spring set correctly the next step is to set the internal adjustments for the draft control the instructions say to use a piece of half-inch all thread which I don't have I just have this piece of half-inch aluminum pipe which works just as well stick it through your lift arms and then press it against the spring this hammer out with the hammer there when that sets the arms in the correct position to do the internal adjustments procedure also recommends to mount this unit on its side in a bench vise which would make this much easier but I don't have a bench vise that's accessible so we're just doing it on the table like this but once you've got the rod in there and got these set which puts the center of your lift holes approximately level with the top of your plate you want to make sure your draft control lever is down in draft that your adjustment stop is on the top side of your lever all the way up and that your touch control is touching that stop that's the mistake I did last time my stop was out here and I brought this lever all the way to here which is almost probably two inches too far which made my adjustments incorrect so make sure you move your stop up to the top and then put your touch lever against your stop okay to make the internal adjustment you'll need a 7/16 wrench you'll want to loosen lock nut up on your plunger shaft here once you have your lock nut loosened up so that you can turn your adjustment plunger you'll need a piece of 3/16 key stock it fits against the housing and in this space here as you can see how much movement I have in this key stock that was because I had that in the wrong position down there when I did these adjustments last time so you take a wrench and you'll want to adjust this plunger to where there's a 3/16 space at the back a little more okay that's yeah that's not too bad that fits down in there okay so at that point you'll want to take the notch here tip this so you can see it a little bit better this notch where this piece rides in and the notch where the front of this ride in you'll want to line those up so there is an in line as possible so when this moves back and forth it doesn't bind because there's those aren't in in line so now they're lined up we'll check again that's a good fit so we can tighten our jam nut back up we will call that adjustment good so that is our constant draft adjustment so now we'll change a few things and do our position adjustment okay for a position adjustment first thing we'll need to do is change our lever up to the position down here is draft up there is position control so once that's in that position you take our touch lever move our touch lever all the way down and that is the position we need for position adjustment touch lever down this lever in position control we still have our rod in our lift arms up against our spring it should be good to go so let's do our position adjustment okay the first step we have to loosen up the nut that's on the front of this shaft and it's up against a plate that rides on this pin so we'll want to use a crescent wrench to hold that plate so we don't break that pin and then use our wrench to loosen that nut and back here there's a 5/8 head behind this spring you'll need a very thin wrench to get down in there to make that adjustment but what we want to do at this point is use a quarter inch piece of key stock back here in the same place we had it before with the last adjustment and adjust this spring bolt to where we have a quarter inch gap here it is really tricky to get your wrench down in there almost okay well that's what doesn't turn tighten up our nut until it's snug with the plate and we'll hold the plate tighten that nut up all the way here's our quarter-inch adjustment so that should completely adjust both our position and our draft correctly well I do know for a fact that when I did this adjustment last time like I said the draft wasn't done correctly so I had to actually take it back off and fudge this adjustment because my lift arms wouldn't go low enough they worked fine but the the bottom stop position was way too high so I had to take it back off and fudge this adjustment to get it to work correctly I'm hoping when I put it back on this time that it will work properly since the draft was properly adjusted prior to doing this before I did any of these adjustments my draft control did not work at all if you had it in position like it is now raised your lift arms up switched it over to draft they would stay up bring these down the implement would drop bring this back up it would not pick up after doing this adjustment procedure the draft now does work probably wasn't a hundred percent properly because I didn't adjust it properly at least at this point the implement would go down I would raise it up and it would bring the implement back up so that was definitely a positive that it didn't do before so we'll go ahead and flip this back over put it back on the tractor with a new gasket and fire it up and see if it works right now we're up in position comes up nice but we still have our jump I think we knew we were going to have let's lower it down switch over to draft control it's coming up in draft which it wouldn't do before and goes back now so at least functionally it's better than it was the draft control now works and the position control works like it should other than that jumping which I'm 99% sure is that shuttle valve leaking past so without finding new parts for that it's not going to get fixed but at least it's better than it was the draft does not work so it is a positive so if you're interested in doing this adjustment procedure to your Jubilee and you need the procedure you can send me an email or a self-addressed stamped envelope and all you to email you a copy of it or send you a hard copy if you'd like it is available on the internet that's where I found it but if you want to just do it the easy way I'll be glad to send you one so I hope you enjoyed the video unfortunately we did not fix the the jumpy issue but at least we know what it is to the best of my knowledge 95% of the time if you have that issue replacing the piston like I did in the previous video I'll link that up here in the corner we'll fix the issue if you have any questions or comments please put them down below please subscribe appreciate a thumbs up have a good day and thanks for watching you
