Hydraulic Help needed

MIcowboy911 · Jun 23, 2022

Looking for a little help with the hydraulics on my 1965 Case 930 CK gas tractor. The PTO works and it you hook hoses up one on each side and use both levers you can use the hydraulics. However the drawbar goes up but doesnt go down and you cant use each separate lever for each separate hydraulic line.
Anyone got a clue?

If the tractor has two remote valves it should have 4 lines to the back. I encountered a 730CK that confused me for hydraulic hookup at first because both 'up' lines were on one side of the tractor and both 'down' lines were on the other, where I'm used to having them paired on either side for each valve, like a John Deere.

I appreciate that. It is helpful. I have the manual but its ancient. Any clue why the draw bar wont go down?

Could be something stuck in the 3-point valving system because water got into the oil.

Bought another 930 diesel last spring. 3 point won't go down on it's own but will go down if you push it down with the loader tractor. Sat for a bunch of years and must have rust in the cylinder bore. Put some weight on the 3 pt. and works good.

You should have three levers. The one close to the seat is three point hitch. This lever slides on a plate. Push this lever forward to lower the hitch and pull back to raise. you can stop this lever any place in its travel along the plate and the hitch should stop also. If the hitch does not go down you need to take the floor plate in front of the seat up so you can see the hitch valve . move the lever forward and back. the spool coming out front of valve should move. if it does not move you will have to follow the linkage from the lever to the draft control box behind the hitch valve. If the spool moves you will have to remove the valve to find the problem. The two levers to the right of the hitch lever are your remote hydraulic . If you have to move both of these levers to make your hydraulics work you do not have the hoses hooked up correct. Follow the hoses to the remote valve the top two hoses should go to the bottom two ports on the valve. the bottom two hoses should go to the top two ports on the valve. All of this is assuming the 930 is an 8 speed and not a 6 speed.

The only way the disc I run operates fully functional is if I attach the left hose to the top on the left and the right hose to the bottom on the right side. However it is very difficult to get them to hook up. I shut the tractor off so it doesnt build pressure and still its tough. The tractor is an 8 speed gas. 4 high and 4 low.
