fast hitch slow to lift

Postby Jerry's cub » Thu Oct 20, 2016 8:18 pm

I have a platform attached to my fast hitch of my newly purchased 55 cub I had about 100 lbs. on the platform and found it to be very slow to lift with idle all the way up. Would this be normal for the old cub? I was hoping it would lift maybe a couple hundered am I expecting to much?

1st thing to check is fluid level in the touch control,make sure it is full

Also check the oil level on the dipstick. If it's above full and the block level is low, you have a shaft seal in the pump allowing hydraulic fluid to leak into the crankcase.

Hi,
Welcome to the website.
To check the Touch Control fluid, have the arms in the rear or down position. The fluid level rises as the arms go to the down position.
If you fill it with the arms ahead, it will have too much fluid in it. If you check it with the arms ahead before adding fluid, it will look low on fluid, unless it had too much already.
If you mean that you are lifting weight with the hitch, with the engine at idle speed, that is too slow a speed. It is normal to have to speed up the engine above idle speed for the system to have full power.
If the fluid hasn't been changed in years, it could probably use a change.
Here is a page from the Cub owner's manual telling about checking and changing the fluid, paragraph 4 tells how to get the air out of the system. At the end of paragraph 4 it says to fill it with the arms in the rear position.
Nowadays they sell Hy-Tran fluid for it at Case IH dealers. It holds 3 1/2 pints, that's less than 2 quarts. :)

Thank you all fer ur responses yes the tractor had sit for better than 2 years, today I drained and replaced all fluids including the touch control unit per specifications. Thank u Glen for the link u provided it gave much more detail than I had previously found, the unit has greater lifting capabilities when it is cold, after the tractor warms up and I have fooled with it a while it will lift less. When its cold it will lift a couple hundred pounds, but the more I fool with it and it gets warmer it will hardly do a hundred pounds. I did notice with Glens link he provided there are two grease fittings on the rockshaft I missed I will hit them with grease tomorrow. Also I am wondering if a flush wud be in order and what wud be recommended something available at nappa maybe. tnx agn guys

Hi,
Glad to help with it.
It sounds like the pump might not be putting out full pressure, or the o-rings in the Touch Control block are worn, not sure which. You could put a pressure gauge on the pressure tube at the left side of the Touch Control block and check the pressure output of the pump. The pressure line is the smaller tube. You remove the allen head plug where the tubes bolt onto the Touch Control block and attach a pressure gauge there for testing.
If you have the under axle exhaust system, you might have to loosen it up and move it out of the way, if the exhaust pipe in in front of the plug.
The page in the link in my other post above says in the note in paragraph 2, to use only the Hy-Tran fluid for flushing the system.
The strainer in the system has very fine screen. If you loosen up any goop that is in the unit, it will get in the screen. That slows the fluid flow if there is lots of goop.
Here is a new strainer at TM Tractor if you want to see what it looks like.
The 2nd link is a page from the Cub service manual showing testing the pressure. :)

Is that screen replaceable without removing the unit from the tractor?

Hi,
No, the screen is in the bottom of the block, it slides out after removing the cylinder head, they call it, on the rear end of the block.
Here is a page from the Cub parts book of the Touch Control, the screen is number 33 in the pic. The screen can be seen if you remove the bottom plate, number 31 in the pic.
The cylinder head is number 59 in the pic. A 1955 Cub should have this part number of block, unless it has been changed by someone.
I added a little more info to my post above. :)

Okay thank you Glen I assumed that was the screen u were pertaining to, so the only true resolve is to do a complete rebuild on the unit.So I assume then the primary pump at front of engine block wud not have any bearing on this.

Hi,
The first thing I would do is check the pump pressure, like I posted a page about above. IH had special equipment for that, it shows in the service manual page that I posted above. I don't know if you need that, or if just a gauge works.
The pressure too low might be the problem.
John *.?-!.* cub owner, and some of the other guys know more about testing the pressure than I do. Send him a personal message or make a new post asking about it, if they don't post on this post. :)

Keep in mind that the pump moves a fixed volume of oil. If there is a path back to the reservoir that allows that volume to go there at low pressure, the pump will not show high pressure. Pressure can be influenced by the pickup screen on the intake side and the pressure regulator valve on the outlet side. If your hydraulics are working some but not properly, the pump is likely to be working. (Your symptom could be a totally worn out pump, but that rarely happens.)

There is an orifice and orifice screen accessible through a pipe plug on the back side of the Touch-Control unit. If these are plugged, the pressure control regulator will not work and you get little/no pressure. Clean these and you may be able to avoid disassembly of the whole unit.

Hi,
Thanks for answering, Jim. What is the number of the plug you are talking about, in the parts picture below. We'd be glad to know what it is.
I've never had problems with Touch Controls much, other than units needing rebuilding with new o rings. :)

The orifice is #32. The plug screws into #59 from the back side.
