Help needed - leaking hydraulics issue

[ejtaylor822]

Chip, Larry and Chris/Soundguy,
WOW! Nice to have three people as knowledgeable as you guys looking at this. More pics attached.

Larry,
Did not check if the bolts were tight - using my hand, they are very tight.

I am so anxious and wanting to dive into this thing. My curiosity is really getting the better of me and really want to get inside of this thing. Will definitely get some pics. Figure if I mess it up or can't get it back together, it still runs, will just load up and take up the road here to a heavy equipment mechanic.

Would be tearing into today, but, the lovely wife got me a flyfishing class/guide for the day for Valentine's day. So, I get to suffer through a day of fishing /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Hope to get into this tomorrow.

Anyway, here are the pics beginning with the left side.

Front view looking straight on - may not be of much value with the top link in the way.

And finally, the right side (looking from back to front on the tractor). I removed the down link to show the rod going to the arm.

You know, the "chenglish" (like that one Larry) manual is not all that good. I remember reading about draft control, but I did not think I had it. Seems like the dealer may have told me that. Need to get the manual back out and take a look.

Now that I look at this, that arm going from this assembly to the linkage on the lifter is there for a reason I would think. I have always been curios why the rubber boot is there at the top of this assy. Looks like to me its there to provide protection and be flexible, especially if this thing is suppose to flex/pivot. Very interesting......

My apologies for my tractor being so dirty - its a disgrace I know but its like I use to say about my old truck - a dirty truck is a happy truck. Picked me up a new Craftsman 3000 PSI pressure washer Thursday night. Going to give the tractor a good hosing off before I get into this (not at full pressure though /forums/images/graemlins/cool.gif ).

</font><font color="blue" class="small">( Soundguy - check it out. If those top two bolts are tite, then item 44 cannot pivot. I am thinking they need to be loosened inorder for draft to work. What do you think ?

Either the bolts need to have some play.. or they fit in a blind recess behind the plate, or just plain fit behind it. Diagram shows nuts.. assuming you don't have to take the top cover off to get to those nuts.. I'd say the nuts go behind the plate.. 77 Hard to tell from his pics.. we need a profile shot as well as a lower shot showing all of the pivot pices and anchor piece. But yes.. I do think it is aprt of a feedback setup.. whether it is fully implemented, or locked out.. hard to say without those pics.

Ok..this pic is telltale guys.. take a close look at this one.. expand it on your screen if using ie6. Part 44 pivots on part 77 via pin 78. Now.. part 77 appears to be bolted securely to the lift housing. However, there appears to be relief room behind 44 for the bolt/nut.. perhas this bolt and nut is a 'stop' limiting max pivot?? hard to say.. but look at that pic right where the bolt is on 44.. not look where the nut would be.. you see a relief int he metal that leads me to believe that part 44 is free floating to pivot on 77.. also.. there appears to be a rubber gasket/oring to keep water out. I'd guess it is fully functioning feedback, assuming you have a draft control somewhere, unless the stop bolts can be adjusted to 'turn it off.. etc.. by taking all the pivot room out.. etc.. That's my unprofesional opinion anyway....

Yep.. this is deffinately feedback linkage..

Ok there is some sort of lever here what does it do?
Maybe this is what is moved (by hand) to allow the yolk to pivot?

And some sort of other gizmo ?

You could damage your tractor by cleaning it. /forums/images/graemlins/shocked.gif
The only parts on a tractor that should be clean (for only a short time) are those parts that have been recently repaired or replaced.

Looks to perhaps be a blank or plate under the bracket and pivot.

That other linkage bar you outlined in you last post deffinately looks like some kind of mechanical feedback linkage. if you will notice, one end is hooked to the lift arm, and will 'cam' arouns as the lift arm lifts... thus pushing that linkafe back.. ohter end of the linkage is on the pivoting toplink rocker.. deffinately looks like it is a feedback linkage.. could be a real crude position control gauge.. or could be for draft. I'd really have to see the parts breakdown and have one in my hand to make a further exact diagnosis.. but I'm deffinately seeing feedback linkages.. not sure how their valving works , or if it is a constant draft / or conventional position controll.. or an inching design..
