CAUTION::: be sure the added control valve is ""open-center"". I'm not sure that the 820/830/2040 open center tractors operated at 2250 psi. I think some research is in order before adjusting the loader control valve relief valve to 2250 psi. I sure wouldn't want you to split the gear pump housing. [Reply]  [No Email]

The parts photo(WP 1704) with the hoses displayed is the way JD engineers thought your tractor should be plumbed for a loader.On most open center hyd's all one needs to do is insert a OC loader valve in the supply line from frt hyd pump(IE cut line and put valve in between) for loader & other hyd's to operate correctly. I'll give it some more thought and reply back later. [Reply]  [No Email]

If so I think you're going to need something similar to parts key # 28 W21205 MANIFOLD ADD 283.93 USD This post was edited by Tx Jim at 12:35:32 09/01/12. [Reply]  [No Email]

Is the small line that comes out of the front pump a pressure line there is two small ones and one just abit bigger a think that is a return line . [Reply]  [No Email]

As TxJim said, an open center systems valves are plumbed in series. So find a coupling in the high pressure line down stream of the pump. Open the coupling and connect the loader valve inlet to the pump side of the HP line. Connect the loader valve outlet to the other open side of the HP line. Make certain there is a relief valve between the pump and the loader cylinders.Or bad things will happen. The loader control valve may have a relief in it ? 2250psi would be close.

Thanks am I on the right track now [Reply]  [No Email]

Is the tractor open or closed center? Is the loader valve open or closed center? There were "three" 830's. The two cylinder. 830 three cylinder open center for the US market built in Mannheim. The European three cylinder 830 also sold in Canada, built in Mannheim and sometimes imported into the US. There were built with either early open or late closed center hydraulics. So it depends what 830 and loader variants you own. This link should get you int the JD parts site. http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.HomePageServlet_Alt [Reply]  [No Email]

As the loader goes it came of a yanmar about the same size so I think the valve is open center. I will have to make brackets to fit I have done alot of messuring and have that part figured out. I just do not have the hydraulics figured out yet.thanks [Reply]  [No Email]
