Rare, What's This, and Strange in the World of IHC

[Michael Mayben]

New thread here, yawl see what kind of oddities ya can come up with that are related to the world of IH junkiron!

Here's one I've not heard anyone jawwin' about:

Jeff and I were going through a buncha used parts he's moved to the barn adjacent to where the new building is gonna be in Grass Valley. He spotted the remnants of an instrument panel from a pickup/t'all and told me to either take it home or he was gonna scrap it. So naturally I wuz on it like a duck onna hopper.

I went to strip out the usable electrics and found sumthin' I'd not seen before on any ihc-produced crap....and it was obviously "factory".

Referred to on the parts list for the '74>'75 pickalls as a "optical ribbon cable and mounting". Serves as a low level illumination system for the cigar lighter, fuel tank selector, and a few other points on the lower section of the dash panel.

There is a typical instrument lamp bulb mounted inna socket in the center, with for distribution points around the periphery. Each point has an optical fiber cable that runs to various points and is retained by a tiny plastic receptacle.

When the light switch is pulled to either of the two positions and the instrument lamps light up, the fiber optic cable lights up also!

This one unfortunately has some damage to the cables caused by a overheated wiring harness, some of the wire runs were in contact with the small cables and when they fried, the cables were melted in two! But the distribution hub is functional and the unit could be put back into service with the addition of some replacement cable runs.

Keep in mind you kidz that think fiber optics are a relatively recent development in the motor vehicle world, this stuff was available on m/y '74 IH schnizz!

Here's another rarity...a "rear wheel anti-skid brake system". These units were a line-install option beginning sometime in 1972 on pickalls.

This system was sourced from bendix. What ya see here is the "modulator cylinder" and the"control assembly". That's all I have, I don't have the drive rings and sensors for each of the rear wheels.

Again...this is 1973 stuff, anti-lock brakes are not some kind of development from the eurasian automobile industry. And they were use don trucks long before the passenger vehicle industry adopted 'em. And what a disaster they were in the early days!

What a score Mike!!
Ya gonna put them in the binder u. Archives?
I was still in auto school when there was some mention of "luxury" cars getting anti-skid brakes.
One of my wiring diagrams has a note for anti-skid, never seen the real deal.

As you May have noticed (or May not have), there is a one page (16) write up of this option in the 72 t/a trailering bulletin I sent you.

For 1010 / 1110 4x2 models...

Since that document came from your personal collection roberto, I didn't wanna scam it from ya!

But since you mentioned now, here it is!

I believe this takeoff unit I have came from Jeff's stash several years ago...and it's no where near in any kind of servicable condition after being open to the atmosphere for many years. And I've not seen or delt with an actual system on any IH vehicle in all these years.

Personally...I hate anti-lock brake systems and consider that shit part of all these nanny-state mandates...back in the day at least a potential buyer had an option to opt-out!

How about that statement in the last paragraph???? Is that marketing smokeblow or what??? Any tow rig set up properly (along with the companion trailer and it's weight distribution) dam shore ain't enhanced with incorporation of anti-lock system!!! And I'm not talking about class 8 tractor/trailer combos which are a totally different animal. Rear-only anti-skid brake systems in conjunction with an improperly adjusted electric brake controller on an improperly loaded bumper-pull trailer can be a major trainwreck! And the same situation with a gooseneck or fifth wheel tow is even worse! The brake controllers that were marketed back in the day (such as the kelsey-hayes unit that IH sold in conjunction with their towing package) had to be "adjusted" (using the resistor module mounted in the engine bay) for only the particular load that was normally put behind the rig. This took much effort to accomplish and about an hour's worth of time out on a long open stretch of road with no traffic. And if the weight distribution of the toad was altered at all, the resistor adjustment went to hell. If any other trailer (with brakes) was put on the receiver, then the brake setup had to be changed to match that load.

Modern brake controllers can have sensitivity and gain adjusted on the fly, all that changes is the slight amount of sensitivity tweeking based on if the trailer brakes are "cold" or "hot". And if properly selected...they can handle a triple axle trailer brake setup.

The cts-2303 service manual has an extensive section that covers this system....what is referred to in the manual as the "I.h. Adaptive braking system (anti-skid)".

Me, too....

I almost rear-ended a couple cars in rental cars with GM's exemplary version (first?) of abs... Vehicle would not stop worth s*** - even if "used correctly".

My 86 jag has the same setup in the center console. Big bug eye looking lens wrapped around the bulb. The optics go from there all over the dash. So much for being ahead of it's time.

Wouldya' believe that my '69 wildcat droptop uses the same thing to illuminate the tips of the heater switches and the labels for the antenna and top switches? And for some dumb reason, the '73 - '77 grand prix's and '73 - '75 grand am's used plastic fiber just for the cigar lighter socket! Everything else was 194 bayonets...

That last bit May help you find replacement fibers for yours, mm. For all I know, the regals, montes, and cutlasses used them too.

Oh, and lincoln and imperial had a rear anti-lock option as early as 1970, while certain '74 cadillacs and oldsmobiles had driver airbags! How's this for a tag-line:

if you want a vision of the future, just check what america has already invented and ignored...

Tell me about it... In snow, you sometimes need To 'snowplow' the front wheels, but the damned computer just keeps the wheels turning. I wish there was a switch to turn off the anti-lock, like I have for the traction-control.

Ford's abs on their light trucks and vans of the '90's can give you a real thrill when you go to stop on wet or slick pavement.

The rules are you aren't supposed to pump your brakes with abs because it will mess with the computer.

With the Ford system you hold tight to the steering wheel to get leverage to push the pedal as hard as you can through the floor. All the while hoping you will slow down.

The chrysler/mercedes-benz system used from the '80's actually work pretty well--no matter the condition of the road surface you can stop straight every time in a shorter distance than an identical car without abs.

Actually saw a t'all with the "adaptive braking system" installed in it. Kind of scary looking.
