Huber Won't move

This is what I'm using: NAPA Premium Tractor Hydraulic Fluid 10W30 GL-4 All-Purpose 5 gal NHF 85405 | Buy Online - NAPA Auto Parts https://www.napaonline.com/en/p/NHF85405

Thanks, I guess Type F ATF would work too. I'll get the NAPA oil.

Any luck?

No, I have a leak at the top of the pump where the control cable connects. I purchased a pump seal kit and waiting for it to arrive. I connected a test gauge to check control pressure to the pump but don't get any pressure from the pump side. The hose I removed from side of the pump is spitting foamy oil but nothing from the pump itself. Not sure where it's getting air in the oil. Still looking for a shop manual. I have found one for the pump though.

That sounds frustrating

It is, It looks like no one uses them anymore and has thrown out all the manuals. I keep checking ebay but no luck so far. I'll just have to figure it out myself the long, hard way I guess.

How high is the oil showing in the sight gauge?

It's a little over half.

Have you had any luck with this? My Huber has been hibernating under snow for the last few months.

Your situation (a hydraulic whirring sound, a brief movement followed by a stop) usually indicates that the system has pressure but cannot continuously build up or maintain flow.

I decided to remove the pump and take it apart. I have a new charge pump for it. Waiting for a bearing before reassembly. It did not look too bad inside for it not to work. I also have a repair manual for it from Sauer Danfoss. Relief valves were working so we will se what happens when I get it back on. I may rebuild the hydaulic motor too. All the hoses are shot so replacing all of them.

Does the mold board roll ahead and back manually or hydraulicly on these or just solid

Mine is manual. Every other movement is hydraulic.

I'm thinking of removing the hydraulic motor while the pump is out and go thru it also.

I found a service and repair manual from CMI equipment. I will attach it if anyone needs it.

I called Huber Maintainer to ask about some parts and I'm considering buying a parts book also, mainly for the diagrams. Do you find the diagrams to be helpful?

Very helpful. It is a breakdown of how the parts are laid out and comes in handy when reassembling. I found my parts book on Ebay. I think there is another one still listed.
