International 1000 Loader

[Jim Becker]

What kind of fluid are you using?

[pickerandsinger]

I just installed a Henderson loader and hydraulics and what I have found out is , I had to use a vent plug on the aux tank( I knew that but wanted to preform a few tests)...It does exactly what your breather is doing...I have used the loader several times and filled the Aux tank when I used it and same thing has happened...( It only takes about 1/4 to 1/2 a pint to top it off.)....Bottom line is it don't want to be full...Once it seeks its level it operates fine( no overflow)...I tried putting a gauge on it temporarily to check the pressure ( if any) on the situation and the loader did just what you said..Acted jerky and captured some air from somewhere...Vent plug bleeds the air off and pukes out the milky stuff you describe...Works great but don't want to be full...You've got some good advice and 'm not a expert , but I was just telling you from my experience...Wish there was a way to check the fluid level visually, then I could keep track without filling it...Something I've got to look into....Good Luck....Dave

I placed a Sintered Breather Vent on the top of the vertical 4 x 4 post on my hi 1000

I'm using standard, generic tractor hydraulic fluid. I don't remember the name on the jug.

I guess I need to understand the difference between a "breather cap" and a "breather". The cap on top of the reservoir is a breather cap. Is it not? It has the air cleaner-type wiry filter stuff inside of it. It's obviously not sealed, because fluid pukes out of it all the time. Are you saying it's not getting enough air, and I should install a better breather or vent on it?

I'm all for it seeking and finding its fluid level. I'd be perfectly happy to discover that it only wants half a reservoir of fluid. The problem is that when it stops puking, it also stops lifting correctly. It chatters and jumps and barely makes it to the top--and that's when the bucket is empty. But when everything is full (TC, Reservoir, and sump tube) it lifts perfectly a few times--until it pukes all the fluid out again.

I have another question, too. There's an adjustment screw to the left of the control levers. It has a nut on it to lock it into place. What does that adjustment screw do? It seems to be cranked down pretty tight.

Thanks for all of your responses so far. I'm looking forward to getting this thing working right. I've got a job or two for it.

I mainly asked about the fluid to make sure you weren't using motor oil. Generic fluid is OK as long a it is one of the higher quality ones that lists Hy-tran compatibility on the label.

At this point would try:
1) Top it off to the full mark. Leave the filler cap off.
2) Start it up and cycle the cylinders, stopping just before it starts to push foam out the filler. (You must have done it enough times to know when to quit.)
3) Shut it down and let it sit long enough for any foam to settle out (maybe over night).
4) Top it off again.
5) Start it up and cycle the cylinders 10 times.
6) Shut it down and top off as needed. Put the cap on.

If you cannot cycle 10 times in step 5 without it foaming up, carefully inspect the suction line and connections (bottom of reservoir to the Touch-Control filler) for any leaks that could draw air into the system.

There are 2 kinds of adjustments I know of that could be on a control valve. One is a pressure relief valve the other is a flow control to keep the loader from crashing down too fast. Adjusting either one shouldn't have any effect on this problem and could cause some others.

So this is a normal issue when filling the loader for the first time? Wow! Okay. I obviously have a lot to learn about hydraulics. I assumed I would fill it up, maybe bleed some lines somewhere, and be good to go. But I guess not.

I think I'll drain the TC and the loader reservoir and fill both with new fluid, because I'm not sure what kind of fluid is in the TC. Should the TC piston be retracted or extended when I fill it? I'm assuming retracted, like the other cylinders.

There's no way I can lift the bucket to the top and back down even once without seeing the foam fountain. I guess I'll lift it up a few feet and back down and keep a close eye on the foam to prevent any overflow. Or should I go all the way up and then let it down, stopping at intervals?

The sump tube is a new hose that fits very tightly on the loader end. The hose could probably stand to be a smidge larger in diameter to make it slide on better, because it's really tight. I don't see any fluid leakage or anything on it, but I guess that doesn't mean it isn't drawing some air from somewhere.

So the idea here is to let it slowly work the air bubbles out over time, and then it should work normally. And if it doesn't, I must be drawing air from somewhere. I'll give it a shot.

Thanks.

Normally you fill the Touch-Control with the piston retracted. In this case, with the added reservoir, I'd do it with the cylinder extended and retract it first thing after starting the engine.

When you lower the bucket, let it down slowly. Having a tight fit with the hose is good. Is your fitting at the Touch-Control block air tight?

[Denny Clayton]

Some of your questions can probably be answered in the 1000 loader manual. Have you downloaded it? It has lots of good info on set up and operation of your loader.

Go into the pdf manual section above and go to IH Implement and Attachment Manuals. Drill down into that to the 1000 loader operators manual and the parts manual.

I extended the touch control piston as far as it would go. I retracted both loader cylinders as far as they would go. I shut off the tractor and disconnected the sump tube line from the touch control. I filled the TC until it ran out of the filler hole. I reconnected the sump tube line. I added more thread tape to hopefully ensure a good seal.

I checked the fluid in the loader reservoir. It was within 2 or 3 inches of the top already, so I didn't add any more. I started up the tractor and let it idle for a minute or two. With the reservoir cap off, I monitored the fluid with a flashlight. There appeared to be a lot of turbulence in the reservoir, even without activating the lift. I raised the lift a foot or so and then lowered it. The fluid level appeared to rise considerably, but no fluid came out. I raised the bucket a little more the next time and lowered it slowly. The fluid rose to the top and began to bubble out. By the time I got the bucket 3 feet off the ground, I could not lower it without fluid coming out of the top of the reservoir.

I have a theory. It appears fluid comes out of the TC and flows through the pump into the cylinders correctly. But when I retract the cylinder, the fluid seems to go into the reservoir, but it doesn't make it back to the TC. It overflows the reservoir, while the TC slowly runs out of fluid. As long as there is fluid in the TC, the loader lifts smoothly. But once it is depleted, it never seems to fill up again, even though the loader reservoir is overflowing. Every time I remove the sump tube and check the TC, the fluid level is low and needs to be topped off.

I think it's time for a picture.

The sump tube goes under the belly of the tractor and up to the TC. Should it be routed a different way? Should the hose be shorter?

The manual talks about a screen that needs to be cleaned when you flush the system. Where is this screen?

Assuming the sump tube is connected securely at both ends, is there anything else (a blockage, etc.?) that would prevent fluid from flowing back into the TC?

Thanks.

[Jim Becker]

I've run out of suggestions. Your hose routings look OK on this side. You sure you aren't overfilling per the operator's manual? I wonder if you have air trapped in the Touch-Control reservoir that is heating/expanding.

[jpate831]

I don't know. I'm filling the TC until it comes out of the big fill plug hole, where the low pressure hose from the loader attaches. And the low pressure hose is full of fluid when I connect it to the TC. There's not a dipstick on my loader reservoir breather cap, so I'm just filling it until it reaches the side pipe elbow, just beneath the cap.

The only troubleshooting item in the book for oil overflow from under the cap is the boom dropping too fast. I guess I can adjust the flow control valve so that it drops a little slower and see if that helps. The book says to cycle it top to bottom 10 times to remove the air from the cylinders. I've never been able to get past 4 or 5 before it starts chattering again.

Should I check the pressure on it? It seems to lift fine when the TC is full of fluid.

Could there be some sort of blockage in the metal sump return tube (the one under the control valve)?

I wanted to get it working before I took it down and restored it, but I may have to restore it first to see it work right, if I don't figure something out soon.

Thanks for your help.

Post pictures so we can see the hoses and connections on the right side.

[Matt Kirsch]

I have a theory. Your connection from the auxiliary reservoir to the TC, or the TC itself, may be sucking in air when the TC pulls oil from the auxiliary reservoir.

Because the 1000 loader's reservoir is below the TC, it probably needs a perfect seal between them, or else air will get sucked in. Air sucks easier than hydraulic fluid.

Is the plug the right one for your TC fill hole? The later type needs a copper washer or an o-ring to seal. Earlier type is tapered pipe thread and should have some gasoila or carefully-applied teflon tape to seal it.

Is there a connection in the siphon hose that's hose-clamped on?

[jpate831]

Your theory certainly seems plausible. The reservoir seems to keep a full tank and spew out fluid, while the TC fluid level gets lower and lower. The last 2 times I've removed the suction hose from the TC, I've had to add fluid to the TC. Every time I do, the lift works great until the fluid level drops in the TC. Then the lift performance starts getting worse and worse until it will barely lift at all, even though the loader's reservoir is completely full.

For the suction line, I'm using a contraption the guy at the hydraulics place made up for me. It looks to be a cast elbow that screws into the TC, and some type of steel adapter with a ribbed connector for the hose. Then I have the original clamp over the hose, and I have thread tape on all of the threaded connections. The other end of the hose fits tightly onto the loader's tube, so tightly that I can't get it to slide on as far as I would like, but it's enough to get the clamp on. See the pics below:

[Jim Becker]

I've looked closely at all your pictures, can't see any incorrect connections. For the Touch-Control reservoir to empty, air just about has to be coming from somewhere to replace it. Check for other possible leaks. I think all versions had at least one good sized soft plug (some are on top). Make sure they are in place and tight.
