Hi Michael here with another conundrum. This one deals with the draft on a International 1468, but I think a little history should be made known first.
I have changed the pump and a few busted gears along with the T-A and now I have been stuck on the 3-point draft like, like forever. In fact I have had the lift plate off and on so many times I can do it in 5 hours.
Anywhoo, upon first inspection I found that the drop valve had a broken retaining clip in it, so that was replaced....and I didn't get it right so it would catch and the hitch would do all kinds of different things. Each and every time I went back through the lift plate I would get something different.... After driving myself insane I ordered two of these clips and had someone else help me put the new one on. When I took the new old one off I found that because I did not install it correctly it had actually been bent there by catching the spool. Now that, that is working correctly I can get the 3-point to center in the middle but cannot get it to drop or raise by using the quadrant levers. Now I am sure the drop valve and position valve are not the problem anymore as I have deduced the problem to the “draft arm” that comes off the torsion pickup as being the culprit.
The reason I say this is because when I pull the draft sensing arm which is attached to the valves, I put tension on the long spring, I can then use my thumb to push on the sliding part of the valve and do not encounter any spring pressure from the internal spring in that valve. It is as if every thing is in position......now this is where my problem is.
It appears that the upper arm (the one that is Ubolted to the torsion bar has some how straightened out. Perplexing is this is a cast steel curved arm with flashing(?) on it to resist such a thing from happening. What makes me think this is before I pulled it the top of the arm rested above the machined surface of the draft sensing arm for the valves.
My question is: Is this arm supposed to be curved in a complete half circle? The one I have has part of a curve towards the contact part but is straight towards where it pins in to the bar that bolts to the torsion.
It would appear that if I heated it up and re bent it to where I think it should go that by using heat it might bend back under use, but I suppose I could just re-heat the whole arm back up and quench it in oil then blue it with a torch...which would be ok.
The reason I am asking here is this arm has been discontinued and is not available new. And, sadly even agwest does not have a clear picture of it and neither does the repair book. There is a part at a tractor salvage yard but I am thinking it just might be straightened out just the same as this one if this is a weak point in the draft sensing engineering.
Sorry if I make your brain bleed thinking about this.....Oh and I tried to get the torsion bar out and just re-position it but would have to cut some pins and then have them machined the rest of the way out, so that is out of the question.
Thank you...Michael
