1984 International S1724 Shifting Pattern and mystery Engine part

Recommended Posts

So I purchased this International S1724 box truck and I have had to get a few things straightened out before bringing it home about an hour away. I replaced a couple brake lines and new gas, charged battery etc.. So I finished up the brakes today and it's in working order. I took it down the road to test out the brakes and they work great.

The truck has been sitting for a couple years now but it almost seems like the rear brakes were on when I was driving it, but it could just be the 1st gear torque that the rear end has, which brings me to my next question. what is the shift pattern? Up and to the left was reverse and down left was first but second seemed like it wasn't there and I was trying to get the truck going from 1st to 3rd.

In the first image of the engine there looks to be a compressor of some sorts that doesn't have a belt around it and it's definitely locked up and frozen. What is it and do I risk screwing up the engine if I run it without it. The best I can tell is that it circulates some sort of air or oil into each of the 8 cylinders. 

Thanks for the help

That is an "air pump" (part of emissions system) should be able to find new or rebuilt unit,

2nd gear should be middle and up ,  I would drain trans and see if there is any surprises in the oil

Possible it is a rusty shifter rail or problem in the top cover ,

May have rusty wheel cylinders , hardware, etc causing brakes to drag a touch , Lot of oddball problems

surface after sitting dormant for a while

Isn't the shft pattern diagram on the shifter knob?

The smog pump is nothing to wory about to get it home. You'll need one to be smog legal, though, I imagine. Up here in the lawless Great White North, I cut the belts on any vehicle I run.

That "Electrical Brake Motor" is a new one on me! Never seen or heard tell of such a thing, weird!

You would think, but it is not, just a black knob

Yah weird huh. It runs even when the key is not on. Might be that way so that the brakes work even when the truck dies on the road or something.

Electric brake motor is for emergency power assist when the engine stops running with a hydraulic power boost system. 

Sometimes there is a sticker above the windshield with the shift pattern on it

I thought the 266/304/345/392 was gone prior to 84. I am thinking this  is  a U-HAUL special truck.

The #8 spark plug in against the left exhaust manifold because it was supposed to be run around behind the carb.

Looks like a very nice truck with lots of potential.

The AIR smog device is no big deal on or off the engine.

All the IH's that I have seen had a metal plate some place in the cab with model and GVW and engine HP listed.

The engine has cast into the block the CI  of the engine.

Get yourself a service manual set.

Where do I find a service manual?

I was able to move the truck to my shop no problem.

I also found 2nd, was just hiding from me, really needed to push it up in there to find 2nd

Tomorrow will be cleaning day. Then I will start tunning up and changing out fluids.

Took some pictures of the tags on the inside

Looks like a 2 barrel carb, 392's were all 4 barrel but a 345 2 bbl intake could have been swapped in. Curious as to how that engine got in there......I thought they were gone in '79.

The only other thing that I know about the truck was that they rebuilt the engine like 10,000 miles ago. One of the cylinders has a loud knock (maybe the lifter) so I'm probably going to have to figure that out one of these days.

Gas engine production ended at Indianapolis in Dec. 1982, but I don't know how long they were available from inventory.  The 1724 model says it was built with a gas engine, it would have be a 1754 with diesel.  The engine size and serial number will be stamped into a pad next to the rear mounting bolt for the fuel pump.  There is no reason to think it's not a V-345.

By 1982 the gas engines were 404 and 446's, not 345's. I suppose IH could have slipped some older inventory out the back door......Henry did it all the time!

I don't think it has an SV engine. There is no script on the rocker covers that I can see.

Script or no, it's an SV. Rocker covers cut out around plugs, and exhaust manifold bolts all in a line, nothing else it can be.

This is the number cast into the engine block. Does this help?

The only pad next to the fuel pump I could see is attached but nothing is there, No sure what to look for.
