Hope all is well.
I am hoping that some one might have a copy of the flow diagram for the raising and lowering of the lift hydraulics. I am having a concern with the position lever. My work shop manual only has a complete flow chart not specific to the rear end.
The flow diagram could also be one for an IH 2756 or IH 766 as they are compatible.
It all started with the 3pl. While I was working away the linkage started to raise and lower automatically I new I had a leak. The linkage would try to pick the implement up but would drop again after half way. This would repeat over and over, I had the local mechanics haul it back as I had to go back to work.
It was obvious the oil was dumping and some of the orings needed replacing. The guys did that at the work shop & replaced any other orings that didn’t look right…..
All leaks stoped.
When it was reassembled the position lever would only allow you to raise the linkage when you put the lever in the low position and then pull it back all the way to the raised position. Once you attained the position you could stop it. How ever if you had implements on you could not raise the 3pl any further because you would have to lower it first. I mean you couldn’t lower the position lever because of the implements. I hope im making sense.
It’s hard to get a manual with a flow diagram that showed the lower & raise of the lift hydraulics.
The mechanic pulled out the cylinder assembly for the draft control, valve assembly for the drop control and the valve assembly for the draft control.
Any help would be appreciated
