IHC 1000 Loader (Air in the Lines or something)

[jmm_spqr@yahoo.com]

Ok didn’t know, as the old 90 degree elbow that was installed in same location for 20+ years was same type iron pipe. Yes there is very low pressure going through this as a return here a garden hose from the loader reservoir.
I’m good changing it out regardless due to the flaking concept of galvanized. Thanks

That's the fill. It's not under pressure, so an "black iron pipe" fitting is just fine. No need to have a 3000PSI rated fitting there.

Earlier you asked how the reservoir on the loader worked. It works like a siphon. The fluid exiting the TC and going into the loader cylinders pulls additional fluid from the reservoir. As long as there is a solid supply of fluid, it works smoothy. If there is air in the line between the TC and the reservoir, and/or too much air in the TC itself, it won't pull fluid smoothly.

That means there can be no air leaks whatsoever from the TC fill port to the bottom of the reservoir on the loader.

Awesome, I thought so since not under pressure. Thanks for explaining the siphon process between TC/loader!

Sorry to report out after testing, the same thing is occurring, overfilling from breather loader side with initially clear hydraulic then the white whipped hydraulic. Feeling the fluid from overflow from breather, it is about 50° cool to the touch. I don’t know what and how to proceed.
Same ramming sound of air-in the system lifting weight. Was grading for a swale with it and about 38° outside after warming it up.
I will check both reservoirs tomorrow to see levels, before I do anything else.

Looked at loader side reservoir all full, when to TC almost bone dry after topped off. There is a problem with the return hose or pressure for return hose to refill TC. Basically creates air void in TC thus the creamy hydraulic fluid coming from breather. Any thoughts to explore? Thank you

Some pics of your set-up would go a long way.

As I mentioned I think you have to fill from the TC side with the Tee you installed and leave the plug out while you cycle.

A Sam said some pictures of your set up especially the routing of the hoses would help.

Here's some pictures of before and after. Was wondering if I have not been properly running this long enough to full operational temperature for the hydraulics when it is in the 30's? It seems the TC is pushing fluid into the loader system, but not warm enough to return the hydraulic fluid back to TC...thus causing over pressurizing the loader reservoir side? IDK just speculating. I will refill it and do cycling with the TC side plug off again to make sure there is no air in there.

Just a stab in the dark, but I would look to see there is no dip in your red return hose.

I am guessing that is comes off the loader tank lower than the touch control fill port.

A air buble in a dip might inhibit proper flow.

Secondly I would guess that the hydraulic oil level in the loader frame tank must be higher than the touch control fill port.

Disclamer;
I do not own any such loaders!

Another few thoughts:
1) Is there a strainer at the point where the oil comes off the loader frame tank to the red return line?

2) Is the red hose plugged with some debris by any chance?

I do not think it is related to the temperate unless you have a lot of water in the oil. The oil heats up pretty quickly. The hoses look OK to me.

When you are not using the loader the oil goes from the TC reservoir to the pump, high pressure back to the bypass block, to the loader control valve, through the power beyond port in the loader control valve, and back to the bypass block into the TC to operate the TC and return to the TC reservoir. When you are not using the loader, the loader reservoir is not active/ used in the system

When I set up my 130 with the IH1000 and had this problem, I felt I had to get that part of the system working first which I did by filling from the Tee and cycling the TC like a normal bleed procedure. To get the siphon between the loader reservoir and the TC reservoir the air has to be out of the metal tubes, the pump area the hoses, the loader control valves and the TC.

My conclusion was making sure the pump had oil and not air going into it was the first step to making the system work. The pump is only fed from the TC reservoir so that was the reservoir I decided to focus on. If you are not using the loader, the loader control valve is just a section of pipe as far as the rest of the system is concerned.

One thing I just thought of is I have had problems with the metal tubes on cubs trapping air. I loosened the bolts on the flange on the pump ( engine off) till I got oil to seep out while keeping an eye on the level in the TC reservoir. It took some time. This is not the first thing I would try but may be worth putting it on the list.

All thanks, great points to consider… it just shouldn’t be so complicated I would think but it is. Wasting a lot of hydraulic fluids and running risk to tractor T/C my main concerns as I keeping testing.
