IH 1066 Hydraulic problems.

Hey Allan and other IH guru's.

I have posted before about having very poor brakes. Hytran is full, filter has been replaced twice now.

I thought steering and the rest of the hydraulics are on two different pumps.

Basically, I don't have much of anything. The steering is chattering when I try to turn, and kind of just jerks.

I bought a 4 round bale mover that lowers down to pick up the bales. The 1066 doesn't have enough hydraulics left to pick up more than one unless you jam the throttle wide open and "yank" the hydraulic lever in short bursts to make it come up just a little bit by bit.

My Ford 5000 row crop will raise all 4 bales at an idle, but it is a miserable tractor to use in the winter because it has no cab and hard starting below about 37 degrees.

Could both pumps be shot, or am I missing something else? I am thinking about just getting a used 17GPM (70935C91) pump from Worthington's for $150.00 to see if it helps. DOUG
 
Add an extra 5 gallons of Hydraulic fuild to over fill the rear end.

The suction tube is above the fuild level, and if the oring where it connects is bad, which is above the normal level just a little, it will suck air.

The extra 5 gallons won't hurt a thing and save a lot of labor to replace a 50 cent oring.

I have been running my 1086 5 gallons over full for 5 years now. Someday it may have to be torn down for another reason and I'll replace the oring then.

Gary is right, those pumps are pretty tough pumps. A lot of the time if you inspect the pump you'll find an o ring there is broke and it's an easy fix. I've seen a lot of folks buy new pumps then find it's just an o ring when they go to take the old pump out. The dealers don't like taking those new pumps back in a lot of places.
 
Save your self time and money and have it flow rated buy either the dealer or someone that has a flow rater and knows how to use it . We can beat this back and forth for days and still not know . First off you have know idea how that tractor was used over the years and how it was cared for . Yes it maybe just a blowen o/ring BUT not on both pumps . And i am not going to tell ya as with out putting my flow rater on it i am guessing like the rest.
 
Gary makes sense. Air in the system would create the symptoms you describe. I had a JD 2010 nobody could figure out why it wouldn't steer. Turns out a 1" cup plug in the pump suction circuit was left out at the factory. It must have worked okay when it was new, or someone would have had it fixed under warranty. I'm guessing that the trans case (H-L-R trans) must have been air tight, then after 30 years of abuse, the case wouldn't hold vacuum anymore. Gary's right. The missing plug was just above the oil level, 2-3 extra gallons would have fixed it, But I didn't learn this until I split the tractor. For an old rattle trap that thing sure steered nice with that plug in place!
 
Had the suction tube come loose on mine one time, only way to get it to work was rev it way up. Thought pump was shot, but my Son took it apart reattached tube and no problem since.
