IH 240 - cable type followup system

Hi. I need more information about the cable type followup system on my 2 point fast hitch with traction control and tel-a-depth. I am looking for a linkage information or parts. Part 371605R2 Lever, Rockshaft drive unit compensator. Part 371606R1 Rod, Rockshaft drive unit compensator. These parts if anybody has any measurements or pictures or actually the parts.
Thanks.

I think the cable type tel a depth systems on the 240 and 340 were used at the beginning of production, but were replaced with the linkage type, which was a simpler, more reliable set up. I`ve heard that some of the earlier cable type fast hitches were retrofitted with the linkage type as they failed. The lever you need was used on both 240 & 340. The rod is specific to the 240. A place to look would be JP Tractor Salvage in Fredericktown,MO (573)783-7055 ask for John. They specialize in IH parts and are quite knowledgable and friendly. I actually have an original 570 hour 1958 Farmall 240 that still has the working cable type tel a depth, so if you need a closeup pic, let me know. As to how they work, I`ll admit, I don`t know much more.

Mark, do you know at what s/n or even a close one where the type of system changed from a cable one to a linkage one? Looking at my Farmall 240 and I have never seen the two different systems I think I have a linkage type as there is nothing that resembles a cable anywhere to be seen. Could you post a couple of pictures of the system you have on your low hour 240 as I would like to compare to what I have on mine. The s/n on my 240 is 18XX which makes it a model year 1959 240 I believe. You can reply to my email if you like - thanks much for sharing, Hal.

Hal, my Farmall 240 is serial # 1255. I have no info on when they went to the linkage type tel-a-depth. I have an IH service manual for the tel a depth - linkage type. I`ll check the date on back of manual. It may narrow the time frame a little. I will take some close up pics and try and post them on here.

My 1958 240U s/n is in the 1400s, not exactly sure without looking. It has the cable servo-feedback. Mine does not work real well... move the lever 1/2", no movement of the 3 point, move the lever another 1/2", maybe still no movement, move it another 1/2" and it may move the 3 point 2-3". This does not seem like a sticky cable because for a sticky cable, the 3 point would have to move without movement in the cable. The cable moves when the 3 point moves. Makes it kind of tricky when I blade my driveway.

Hello, Mark. I have 2 International 240's (both around serial no.4202&4106). 1 with cable follow up and 1 with linkage follow up. The one with the cable follow up, if you could please post some photos of the rod with a tape measure next to it. Because I would like to get a length where the bend is and how long the rod is, and I would like to see if I could fabricate one. And if you know where I could get the lever that would be great. Thank you. Bruce

I`ll try to get you guys some pics this weekend.

Well, here goes nuthin`. Was kind of hard to get decent pictures with the tractors parked so close together !

Hi,Mark. Thank you for the pictures. This will help me a lot. One question: when you measured the rod, did you hook the tape measure end on the stud that is attached to the cylinder?
Thank you. Bruce

Yes I did. Should be real close to 16 1/2 " center to center. Note that there is adjustability built into the rod on the top. You will need that too, I`m sure. Good luck and let us know how it turns out.

Measured the rod on mine this afternoon and it's just under 17" c-c. I'm not sure what any adjustment would do at that point in the linkage. It may be something that is set during assembly and does not need any further adjustment. I also watched mine real close while moving the control lever, cylinder travel and cable travel. I appears when the hitch moves up, the cable follows instantly, but when the hitch goes down, there is a lag in the cable moving... this does not seem right, it should follow immediately in both directions, I would think. It's like there is slack in it, but only in the down direction.
