super M hydraulics problem

I"ve had this 1953 super M three years. It has the live hydraulic pump up by the distributor and motor oil fill, and a reservoir behind and under the gas tank. I added a 3pt hitch and ran the line out of the left side of the reservoir. For two years the 3pt hitch worked great - came up quickly and would hold at a position when I put the hydraulic lever down to the first notch. The reservoir has always leaked some, and I have had to add oil (used nondetergent 30 wt). The problem is that the 3pt hitch now won"t hold its position. It leaks down rapidly. The pump seems to be OK in that it will quickly lift whatever"s on the hitch, but within 10 seconds or less you have to relift. Any ideas on how to fix this problem? Thanks for any help.

SHOULD USE EITHER IH HI-TRAN OIL OR LIKE A CENEX BRAND GREEN QUIKLIFT. MOTOR OIL WILL BURN IF USED A LOT,

THE LIFT CYLINDER MAY BE LEAKING INTERNALLY. IF YOU HAVE QUICK-CUPPLERS, UN HOOK THEM BOTH AND IF IT GOES DOWNTHEN, YOU NEED A CYLINDER REPACKING.

Good idea, but there's just a direct line to the reservoir. I put the 3pt all the way up, took out the breather plugs to look for oil, and then let it leak down. Very little oil appeared, and none actually flowed out of the vent hole. When I got the tractor someone had added about one foot of pipe (2 inch diameter) to the fill hole in the reservoir. I thought at first that it was so they could easily add oil if needed, and since there was a corn picker mounted on the tractor some piece of the frame made it difficult to add oil. After about a month I realized the reservoir box leaked - oil was always on the platform and I had to add oil on a pretty regular basis. Anyway, I figure that in order to stop the oil leak I just as well work on the reservoir, so I took it off yesterday and will do through it this week. When I run into problems there's a case/IH dealer nearby who should be able to help. And, thanks for your idea. I'll use a different fluid in the system when I get it back together.

I WOULD HAVE MADE SURE THE CYLINDER WASNT LEAKING FIRST BECAUSE THE AIR THAT IS TRAPPED IN THE LINES WILL CAUSE THE OIL TO LEAK OUT OF THE BREATHER EVEN IF THE SYSTEM IS LOW ON OIL. 1000 PSI WITH AN AIR BUBBLE-ITS LIKE A GOOD LOUD FART, IT HAS TO COME OUT SOMEWHERE.

The SM service manual says use motor oil in the shaft driven pump and 7 qts of IH Touch-Control Fluid in the live pump.

Another dumb question - isn't the oil in the reservoir the same as the oil in the pump up by the distributor? Is the live pump the one up front or the one in the reservoir? I don't understand why there are two pumps anyway. Thanks for your note.

THE PUMP BY THE DISTRIBUTOR AND THE RESERVIOR UNDER THE GAS TANK ARE ONE UNIT. THE LIVE PTO IN THE BACK OF THE TRACTOR WITH SPLINES IS ANOTHER UNIT THATS RUNS OFF THE CLUTCH AND TRANS. IF THERE IS ANOTHER PUMP UNDER THE FRONT END, THE PUMP BY THE DISTRIBUTOR IS WEAK AND THE ADDED THE PUMP AND USED THE RESERVIOR FOR THAT FRONT END PUMP. DISTRIBUTOR PUMPS ARE QUITE SPENDY SO THAT WAS THE NEXT BEST THING.

If you are looking for a working fix and not a pure IH fix, you can get a new spool valve from northern tool and work your 3 point with that. The spool valve is what hold the 3 point up if the cylinders aren't leaking.

Thanks! Do you have a phone number or an email address for northern tool?

I found the northern tool website - they've got a lot on hydraulics. The two hydraulic cylinders that are on my 3pt hitch (Chief brand) are the cheapest they list at the Northern site. Do you think both cylinders could have gone bad with two years of use? Thanks!

No easy fix -- if it is not the hydraulic cylinder on the hitch, you have to remove the reservoir and rebuilt it -- neither difficult or excessively expensive, Case-IH still has the parts. Have fun getting the control lever in the right place when reassembling!

If it's one of the two cylinders that works the 3pt, shouldn't the other cylinder still hold up the hitch (with no equipment attached)? Where can I get directions on rebuilding the pump in the reservoir? Does it take any special tools? Is 30 wt nondetergent OK to be using in the reservoir? Thanks for the help!

You need a parts manual, there is no service manual specifically for the Super M, there may be one forthe hydraulics. Call Binder Books at 503-684-2024 and ask about their manuals. A parts manual is essential, because if your memory is as bad as mine, you won't rememberhow it goes together. I don't think the problem is in your cylinders, if as you say you have two of them. Use Hytran in your system, SAE 30 might work, but 30 is a little stiff. It takes no special tools, the biggest problem will be getting the control lever hooked up right, as you cannot see what you are doing as you close the reservoir.

Thanks, I'll check out binder books. I got a manual for the 140 from them two years ago. Does the control lever have to come off for the rebuild? It looks like mine is securely attached. Thanks!

Valve body in reservoir has a check valve to keep fluid from leaking back when out of lift mode, It may be leaking.If using single acting
cylinder fluid will blow out vent if its bypassing.

The 3pt has a single acting cylinder. When you say the fluid will blow out vent, do you mean the air vent on the cylinder? I've taken both of them out (the vent from each cylinder on the 3pt) and let some fluid run out to try to get rid of any air pockets.

When using hydraulic cylinder single action,idealy there should not be any fluid on vented side of cylinder.In real world use theres
usualy a little.If your cylinders are bypassing internaly you should see more than a little oil vent out when you raise 3 point full up after tractor sets long enough for cylinders to leak off.I suspect its the check in valve body if I had to guess.If you have a manualy operated ball valve you could put in line to cylinders,raise them and shut valve,if they stay up its not the cylinders.

I think I understand. I'll work with it today and check on the amount of fluid that comes out the air vent valve. When you say you suspect it's the check in the valve body, is that the valve in the hydraulic reservoir or in one of the cylinders on the 3pt? Thanks for your help!

Sounds to me like you might have a leaky seal in one of your lift cyl. Isolate each cyl. if possible in your system

If there is a bad seal in one of the cylinders, would I see fluid leaking from the cylinder? I've got one hose going back to the 3pt, where it then T's into each of the two cylinders. I could probably plug off one of the lines and isolate each cylinder. Thanks!
