Loader Weak loader troubleshooting?

[gatordog]

I have a 1980 IH 784 I just bought that has a Rhino Loader attached. The loader is in great condition. the lines look factory new and no leaks. The problem is when I go to lift the front axle off the ground the hydraulics kick out very quickly, it does not even try to lift the front axle. The lines that feed the loader are controlled by a 3 position handle on right side, under the draft and lift control. When the loader loses power, I have to cycle the controller and return it to the middle position in order to regain power to the loader. I will be changing the filter and lowering the oil level (it is currently way over full) this weekend weather permitting.


There is a bolt and bracket that can be used to lock the tractor controller that feeds hydraulic power to the loader in one position, should I try to lock it in a position to keep it from kicking out the pressure to the loader?

I know that this tractor controller is for any remote attachments and it is designed to kick out when you hit the rams limit. There is what looks like and adjustment on the loader where the main line comes in, what does this do?

The tractor pump flow is rated at 13 gpm, but I have not tested it since I don't have the gauges to check. Any ideas where I can get the testers?

I had a 574 IH and I'd lock the lever in place. Worked fine like that.

Thanks I will try that, just did not want to exceed any pressures and damage something that would be hard to repair.

I'd be going to dealer to get the power beyond port to illiminate the rear outlet use. By going through the rear disconnects you are probably losing about 1/3 of your hydraulic power.

Hi again, see my post to you on the Case IH thread, that should answer your questions???
