After putting my Dad's IH 444 all back together, we filled the lift housing with 3 gallons of oil, then the trans with 10 gallons.
I started the tractor, first ran the power steering back and forth until it was smooth. Then tried the 3pt lift, that worked smoothly.
I ran the loader up and down a few times, it was very jerky, the pump seemed to be intermittently cavitating with air. I shut the tractor down and put 4 more gallons in the trans. (I was told when the IH 444 has a 2000 loader, it takes 17 gallons total, 3 in the lift housing, which leaves 14 for the trans).
With the 14 gallons in the trans, the loader pump is still not working right, I can't seem to bleed the loader system by just running the boom & bucket repeatedly to their full extents.
Is there some type of bleeding procedure for this tractor + loader?
I own many HYD machines, CAT and Ford, I have always bled by just running the circuits to the extents a few times.
I'm wondering if this IH 444 has a bad pump on the front. The hydraulics have always been jerky.
Also, when the tractor is shut off, the 3 pt falls pretty fast with an implement attached, it doesn't stay up like it used to.
