IH300 Utility hydraulics

There ya go!! =)

One has to wonder what would cause such an instant filter clogg. As evident by my experience, the pump should have more then enough suction to collapse that filter and suck a hole right through it, altho not necessarily.

How cold was it when u ran it?

Even tho you added a half of a gallon, if the original fluid has water in it, water could be in the system freezing up the filter and blocking flow.

When the movement was "choppy" did the pump make a horrible sounding noise, mine does if the res is low and I try to lift the loader arms too high. What line dide u blow?

The noisy pump sound stopped and I was guessing low fluid let air in somehow. No change after I added fluid, wouldn"t move the pistons to work out any trapped air. Ok, I won"t crack a line to test.

Now sounds like it might be a frozen water in the line somewhere. We had a big thaw today around 40 deg, so I"m hoping the problem goes away. I don"t see how the strainer is the problem unless it suddenly clogged up, which seems unlikely. I"m thinking about heating with a torch, but haven"t a clue where the ice block might be, if there is one. Any ideas?

Hope you get her working...

Hope you get some use out of it, not the best scans, but readable to the extent mine is. I got it at case IH, so...

I also got an 18 page booklet from a member here I could scan. It deals manuals with the farmall 300 and 400 series hydraulics, but it is for the most part very applicale to the 300U. I plan to scan it, and if you would like it, I can scan it within the next few days.

Maybe I should put it in a zip for. Thats a shareware utility and will open the file without having to pay for it. The prog is called winrar.

If you need the zip instead, just let me know.

You study that hydraulic system a bit Farmall 300 and Utility 300 have all the same components, just a different configuration. Same with clutch and TA if so equipped.

I agree it would be much nicer if you had the Utility manual. Why not go through YT classifieds, photo adds or look at ebay. There are manuals galore on ebay, you just might find one. Then you can sell your current manual same way, for now it's better than nothing. I find my best source for manuals are flee markets at antique tractor shows in the summer. You see what your getting.
