1570 case hydraulics

We just bought a Case 1570 tractor. The engine seems to run good but , the remotes don"t have any pressure and the 3 point arms have no lifting power , the power shift acts like it is trying to work but slips if you try to put some load on it.The brakes and power steering seem to work good. We changed the hydraulic filters and checked the pressure regualator spring .
I was wondering if there are common isues with the pumps on these tractors . I know there is a charge pump and a main 20 GPM pump.
Thanks for any help.

I have a 970 with similar problems with 3 point hitch did a partial rebuild on the remote valves and don"t use 3 point for heavy work. Don"t like the sound of the power shift slipping that sounds like it might be $. I have a 1070 and a 1370 both power shift and never had them slip

sounds like a power shift problem. I think on the 70's the power shift gets the oil first then whats left can go to hydraulics ect. If a seal is blown in a clutch pac you loose all your oil and have nothing left for hydraulics. You need to test it with some gages that hook to the valve body. There are others on here that know more about this than me, hopefully they will help you out.

you need to get some coachin from mEl .,, he is good as they come ,,. good ihc mechanic said the best thing about the 70 series Cases was the engine , it is hard to disagree with that statement ,, case shoulda put a park pall in their tranny , instead of relying on e -brake ,, i like the p- shift in my 1070 , but , sadly you can;t just put any one in the seat, they are not idiot proof ..

to j hikemper If you can tell me how to get in touch with mEl about the 1570 case hydraulics, I would be very greatfull.

they did put park in the 76 and later 12-1370's and all 1570's but like you said they were not idot proof either, but I did like them better than the hand brake, sorry am not giving out guess's on the RPS any more to many varibles and if I am not able to have hands on the machine and domy own flow test, operating tests and such would be pokig in the dark cnt

CN1660's got it right, a flow test is mandatory in your effort to isolate the problem. The test can be done through the remotes and all the powershift and hydraulics can be tested with one hookup. When testing, the flowmeter should be set so that the remote pressure is under what is required to kick out the spool holding plungers in the remote valve, flow should be checked in all powershift ranges plus clutch down and reverse and any loss of flow at the remotes in different ranges will indicate which clutches are leaking and how many gpm are being lost in each clutch. mEl

Jack, can you give us a little more information please.

1) Does the tractor move at all in any gear?
2) Have you gotten a pressure reading from the rear remotes? If so what is the pressure. (you can screw a gauge into a ISO tip to get the reading)


You really need to have a flow test done to isolate the problem. I don’t know what it will cost you but it’s worth the expense. Otherwise you’re guessing and with the high price of parts a bad guess is expensive.

That said my first guess is a possible charge pump failure. It’s serviceable without splitting the tractor.(underneath the tractor where you changed the filters)

It’s also possible to have a main hydraulic pump failure and cause a similar problem.

Even a bad/slipping torque limiter clutch can cause a similar problem. (means a front split, not as bad as it appears)

On my 1370 the C4 clutch failed plugged up the internal screen and caused a similar problem. (Let’s hope that’s not your problem.)

P.S. you can rig up a set of test gauges to test the Power shift.
I bought 5, 300psi gauges mounted them to a piece of angle iron then attached 7ft long ¼ hoses to them. The hose had a fitting to connect to the gauge on one end and a jic male end on the other that screws into a 1/8 swivel adapter to a corresponding port on the cover plate for the power shift.

This is in regards to a 1570 hydraulic problem I had originally posted back in 10/10/11 . We finally have some time to work on the tractor. The tractor does move on its own. We can hook on a 21 ft disc and pull it just fine . The power shift doesn't work, the remotes have vertually no flow and the arms have no lifting power. We removed the main hydraulic pump and found the brass plate on the end of the pump gears was broken and blown out. The gears look good and the pump housing is not scored. My question is , can you get parts to rebuild the pump or do you have to get a different pump? If so where or who should I contact?
Thanks again Jack
