D301 Diesels in '61-68 Light Line Trucks

Recommended Posts

Hey all,
 
Putting the finishing touches on an article in Diesel World on this very elusive option. And, yes, it's for real... and makes IH the first to offer a diesel in a light truck. 
 
I found a lot of information on them at WHS, though it was mostly from the very beginning of the process. Because they made it a "Special Feature" rather than a regular production option, you won't see it listed in the normal places like a brochure or a Data Book. No doubt they put out some sort of an announcement to dealers but I haven't found a copy of it yet. The dealers knew how to order them, as evidenced by LSTs from all over the country.  The LSTs are pretty normal, but for the engine and a very few changes needed to the truck. There was a supplemental-style parts listing for the unusual parts needed, but really there weren't that many. Since they were putting the engine in the Loadstar, and had offered it in the B-160 and BC-160 in '60-61, and the engine was built around the BD Series architecture, it fit well under the hood of a C-Line truck.
 
I'm just putting out one last shout in case someone has one more little tidbit of information. I've harvested all the low hanging fruit, a a good deal of the upper tier stuff, but this is a pretty eclectic group and may have something more.  Below are some specific questions on rumors and unconfirmed information I'd like bunk or debunk:
 
-Supposedly, Scotts (the fertilizer people) ordered a big batch of these trucks at some point. Some of the rumors have this being up to 400 units .
 
- Part two of the above says the Scotts thing happened early in the D-Line era. That is remotely possible since the D301 was still available in the Loadstar in 1969, but that was the last year for it. Another related rumor has the D301 available in '69 Light Line trucks as it was the previous years.  While the automotive version of the engine was available in that year (it would be a combine/industrial engine from then on AFAIK), I don't know if it would fit in a D-Line body. The C-Line cab was built the fit the Diamond series engines, so it was an easy fit. Those engines were gone by the time the D-Line trucks came out  so it might not have been a good fit. I KNOW IH wouldn't do a low volume option like this unless it was easy-peasy.
 
-The earliest known D301 light trucks are 1964 but I have a nagging suspicion they might have come earlier and I'd like to confirm that (or not, as the facts decree). I know they experimented with installing this engine in B-Series Light Line trucks but the engine wasn't announced as an RPO for the medium duty line until April of 1960 and then was announced as being the base diesel option for the Loadstar late in 1961 ('62 MY). My theory is that the light line diesels could have appeared as early as 1962, but I am sticking with the confirmed by LSTs 1964 number until I know better.
 
-Thus far, I know that they were available in all the pickups. They are confirmed in 1100s and 1200s, long and short wheelbase, regular bed or Bonus Load, or Cab & Chassis. Also, one Travelette has been found. I'd like to know if it was possible to fit the engine in a Travelall?  Would there be any reason why an engine that fit in an 1100 or 1200 pickup wouldn't fit in a Travelall? If they would, then it's a least possible that in one of the known four years of production, somebody might have ordered a Travelall diesel (and wouldn't I like to be the lucky SOB that owns it! ( : < )
 
-I am collecting D301 engine numbers, any application from trucks to combines. Thus far, it looks like the serial numbers on the truck engines (all GVWs) are sequential, the highest being in the 8,000 range. I don't have any combine numbers, nor for the marine applications, industrial (loaders, etc) or stationary power plants. Because the automotive engines had significantly different calibration than an industrial engine, it seems logical that there were different series of this engine and maybe a new set of serial numbers. I'll know once I collect more numbers.
 
-Would like to hear about any other trucks. I have Pat Putnam's two, the one Brendan Barnes sold, Joe Yackley's, Charlie Horton's and Shawn Bailey's, plus a couple of others that were for sale on the web at some points in time.

Jim Bob Holculm who lives near Springfield Oh. has the C-130 4wd that was used as the test mule and ended up being used as a yard mule for pulling "dead" new trucks off of the line.He put a 392 and Allison transmission in it when he got it. I believe it was a 62 model. It had the recessed grille and dual side by side headlights. He still works with Navistar in Springfield.  Eason

Thanks Eason. Yeah, a '62 test mules fits into the theoretical timeline pretty well.

The story is submitted. The tip to Bob was a good one and his truck appears to be some sort of a former test mule. The entire story is sketchy but it looks like it was built, sent to engineering and the diesel was installed. The LST bears some of this out indicating it was a "Sale to Works" deal. Apparently it was tested for some period of time then became a yard hack used to move dead trucks and parts around in Springfield. Did that for a couple of years and then was sold. Before the sale, the diesel was removed and sent back to Melrose Park and a Black Diamond was installed. Uncovered some D301 powered C-Line Travelalls as well. Anyway, this was a very interesting story to do.

March 2018 Issue, which will come out towards the end of January

If I find a C-Line diesel T-All, I'm likely to keep it for myself! ( : < )
