230 hydralics

I just purchased a 230 and with a tune up and a carb kit, it runs like a top. Water pump needs rebuilt or replaced, it is making noise and leaking. I see there a rebuild kit available or should I spend the extra 40 and just buy a new pump?
Next question, and I'm really confused on this one!!
The tractor has the hydra touch and also has the extra valve for, I assume a fast hitch that is not on the tractor. My super C has the same valve and a fast hitch. When I move the touch controls the lifts work really fast, and you can't stop them. They go to the forward position on their own. The extra valve also moves the lifts. Is something haywire here.

Something is wrong, but I don't know for sure what. Are the lines for the F-H valve blocked or looped together? If they are blocked or plugged, the pressure must be feeding back into the system somewhere and whatever is causing the Touch Control to act the way it is causes the T-C to move. I'm not sure what kind of "feedback" there is to locate the T-C arms, but it's probably mechanical... or when you move the levers X amount and when the arms have moved X amount the valve is back in neutral. If that feedback is stuck or disconnected, the arms will move to the end of the stroke. that's how the 3 pointon my 240U works... cable from a pivot on the 3 point feeds back to the valve so the valve "knows" when it's arrived at the right place according to the 3 point lever.

I would get the new water pump. It will save you the time and effort of having to do it again when the rebuild kit does not work. It is a lot of work to remove an old pump and replace it. The labor alone is enough to suggest a new pump. You might want to get the radiator boiled out while you have the pump off. You also want to get a new bottom hose and clamps.

Check the oil level for the touch control. Sometimes being low on oil can cause erratic response. The touch control should function totally independent of the auxiliary valve and should generally reflect the location of the control lever just like on the SC. When we would remove the 2-point on our 200 (for the corn picker) we would remove the auxiliary valve control lever. We also would close off the hoses with pipe plugs. It did not affect the touch control which raised and lowered the corn head.

The auxillary valve is capped off. So when you actuate the valve, backpressure must be getting back to the t-c and moving things. I will check the oil level and verify it is full. The tractor has no fast htich, draw bar or nothing on the back. I thought about putting a drawbar on it, but maybe I'll look for a fast hitch. The scrappers got to the farm before me and I'd bet the fast hitch is Chinese cars by now. It was a flower and vegetable farm. There are still 2-SC and2-C's there. All the mounted equipment is gone to scrap. I have been promised to get to pick over the tractors before they get cut up, but they are still trying to sell them complete. I see a set of duals on my SC or 230

Problem with working on a Touch Control is that it's all internal in that box under the gas tank. Can't see anything but the input levers and the output arms. Yes, the T-C should operate indipendantly of the Auxillary valve, but there is only one pump and the systems are separated interior of the system, so there has to be a flow control of some kind to separate them. If whatever valve is there to separate them is malfunctioning, one can affect the other. I'm looking in th parts breakdown to see if I can determine what it is... would be a alot better if the parts book included a hydraulic schematic.
Each cylinder in the T-C has a "front" and "rear" what IH is calling a check valve.I'm thinking this has something to do with locating the arm when the lever is moved, but without the schematic, I can't tell how they work within the system. there is a cover on the rear of the "box" and these valves ar behind that cover. There is also a "safety" valve, which I'm assuming is the system relief valve. Also a "pressure control" valve, and with a "safety" valve, I don't know what this valve is or does. Sometimes there are "circuit" reliefs that are set lower than an overall system relief, so the PC valve may be for the overall pressure, including the auxillary valve circuit and the "safety" valve may be for the T-C circuits. maybe a service manual has a schematic, but I don't have one of those. My parts book covers the 200- 240 tractors.

Here's a breakdown on the Pesco pump. Hal

There arent any lines coming off that valve so it cant do anything. Now check your linkage to the arms from the levers as there is stops on the housing that need to be set so the arms can move with the levers for them you can run lines off the control for another remote cycl two way.

Thanks for all the advice, will update as I progress through these problems
Thanks again

BTW, your 230 has the older "Touch Control" system on it.

Most 230s came with the newer "Hydra Touch" system, which did not have any arms up under the gas tank. Touch Control could be retrofit at the dealer, or special ordered from the factory, to make the 230 compatible with old C & Super C implements.

You've got some sort of backfeed problem going on there. Don't pull the auxiliary valve lever because that part of the system is deadheaded.

Can't really tell what's going on down there from the distance at which you took the picture, unfortunately.

I believe Kevin at Silsbee Tractor had some tractors that should be able to supply the missing hitch parts. No email Call him at (409) 385-0055
