Why The Demise of IH Ag Division?

[ccguy]

Thank you all for this information. Really interesting...and very sad of what could have been. I wonder what their lines would look like today.

I've got to track down an affordable copy of that book....

Like I said, the power train, or the "base machine" is the same. All as he would have had to do was split an 88 and Magnum and bolt the two together, then make the hoods fit the cab, and engine controls. Not really that difficult.

I just wanted to follow up on this because I found the video of the builder, Danny Anderson, explaining the build. He states in the vid it was a direct bolt together. Like I mentioned, he just had to modify the hoods and some other minor things. His description starts at about 4:30.

Sorry guys, can't leave this alone today.

Apparently one did make it out of the Hinsdale after the merger. Dirtboyz, (the guy who built the 5388) confirms the authenticity of this photo. He says it is the only one that made it out. Can't find much info on it, but it's really cool.

Three pics about half way down the page.

I've seen pics and read about this s tractor on redpower.com too Jon, pretty neat! For those who say or think the magnum was a case design that's a bunch of bull! We had a neighbor friend who was diehard john Deere and he bought a 7120. I used it to disk some , man that was fun to drive! You could definitely tell the cab was an IH.

I find this topic very interesting since I'm not very knowledgable about it. I watched the video Jon linked, then half a dozen more. I'm a little confused. This guy made the 5388, mating the 88 series with the power shift trans. One video about the 7288 I watched commented about how the trans in it was the same trans design as the 5488. You can smoothly shift to any gear, any quadrant any time....is that not the power shift trans? What is the difference between the 5488 and homemade 5388?

The STS tranny wasn't a full powershift but it was synchronized. You had to clutch to change ranges and to shift 2-3 and 4-5. Magnum was full powershift version of the tranny. If you've run one the 6-7 and 12-13 shifts are a bigger 'bump' for lack of better term, as that was a range shift.

Ok, that makes sense.
Thanks!

Not that SS5150 didn't do a good job, but let me take it a little more detailed....

The 88 series was a gear drive. It had two shift levers, the range lever, and the speed lever. The range lever also contained reverse. The larger tractors had three ranges: High, Medium and Low. Then in each range you had the choice between gear speeds 1-6. The trans still had the the IH Torque Amplifier, but it was changed to an electric shift and incorporated into the speed transmission. So, you could shift between speeds 1-2, 3-4, 5-6 with a simple "slap" of the shift lever from side to side.

When they (CIH) went to a full powershift trans. All they did was add some clutch packs to the STS and boom, full powershift. When SS5150 talked about the "jump" between some of the gears, that is when it shifted between low and medium and medium and high. Single lever in the cab, forward gears numbered 1-18, two ranges of reverse. You could choose rev 1-2, and go to neutral and back to another notch and choose reverse 3-4.

The transmission housings on the 88's and magnums were the same. The early Magnums actually used the left over housings. Kinda neat to see one with the IH and original casting/part numbers on it. Several of the parts are interchangeable.

Another neighbor friend had a 3688 that I disked some ground and planted wheat with in the fall of 96. Kinda neat compared to a 86 series( I used to run a 1486 a lot ) from what I remember it may have not had the tranny update cause it gave me fits shifting . Dad always said it was the best looking tractor IH made. We tried buying a 5088 in 87 but couldn't come together on the deal. We had on our farm at one time a 656d farmall, a 1486 a 76 886 360d and one dad bought new a 81 886 with a 358 German diesel, it had a cab originally intended for a 986! Must have been put together from all the extra parts IH had around. Really it had 986 on the cab serial # pretty cool! Have to see if I can find a pic of the tractor. Kinda funny story dad ordered it they first tried to pass a used a 886 off on him then the other one came in it had the wrong size tires. He ordered it with 18.4x38 and it had 18.4x34 on it, turned out the 34's were better. Smaller tire like that gives you better pull for the up the tractor had. Sorry to ramble. This is a interesting thread! For us IH guys there's no better book than red tractors 1958-2013 very much interesting book!

Brian, that's kinda odd..... the 886 with the German diesel....
The cabs were all the same of the 86 series, and they carried their own serial numbers. I'm wondering if perhaps it just happened to have 986 in that number? Now the D358.... that's just odd. That was the engine for the 786. Perhaps a mistake? Very, very interesting.


On another note, I got the book "A Corporate Tragedy". Local library got it for me. Beat the high price tag. Started reading it Friday night. I'll probably finish it in the next couple days. The history of IH is fascinating. The McCormicks were in the very top of the 1%'s of their day. Incredibly wealthy. Company was too. Every die-hard IH'er should read this book. Barbara Marsh did her research.
