I don't know what the shift pattern is but it only feels like there are three spots up and three spots down. It did shift fairly easily.

The shift pattern would be on a printed sticker, directly ahead of the shifter, on the dash. Yours is missing?

Going from memory as Dad had a '54 R-160, Reverse and first took a longer throw to put into gear than 4th an 5th. 2nd and 3rd were somewhere in between. Oh his, Reverse was to the right and up, 1st below that. 2nd was to the left and up, 3rd below, center and up was 4th and 5th below. No 2-speed on that one.

At that point, the stellite/sodium exhaust valves would break! in 1955 they went to the green diamond, which for all intents and purposes was a 'modern engine'. The dual rear window L series trucks came out in 1949 - the 1950 model year. In 1950-51 model trucks, the doors had internal hinges. in 1952 IHC went to external hinges and also made changes to the front grill.

If your truck has its original glove box, carefully remove it. The original built ticket was placed there, on top of the box, at the factory. It will be a fragile paper ticket with engine and running gear noted as well as options fitted. It may be glued in place (mine was). I had the original from my 1950 L-120, S/N F-9108. First number was year built, numbers following were actual S/N (built 1949, 108th of the model. The build ticket had the actual assembly date on it - Oct 1949.

IHC never used poured babbit in any of the engines they designed. They had inserts from the beginning. The early OHV engines (from at least the early 30's) were wet liner! They later went to dry then bored the cyl right in the block. They were way ahead of their competition. I think you are thinking of Chevy, they used poured babbit into the 50's. The SD was an IHC designed OHV that replaced the Flathead GRD which was NOT Ihc designed.

Cornbinder, who designed the flathead green diamond engine or who built the engine?

It was originally a Willys design and built out of house (I think Wilson machine co). IHC needed a small engine for the lightest trucks. They had been using Lycoming. They bought the rights to the engine by the 40's and the molds then had Green Diamond in the casting. Before that point they were called HD and while similer, there are a few differences.
The IHC designed engine of the time were all OHV and Wet liner, They were too big for smaller trucks they later became dry liner and then parent bore. IHC didn't know how well lighter truck would sell, and didn't want to invest in an engine until they saw they sold better then the bigger ones. By the 50's they decided to build their own small six for the light trucks, Naturally they went OHV and gear drive on the cam like all there own engines.

I always thought the green diamond engine was a better built engine than Willys flat head four they put in Jeeps.

Bryce D, are you sure your truck has air brakes, I don't think I have seen a truck that has six bolt Budd wheels have air brakes.

It was and it was a 6 cyl but the original design was by Willys but never used in production. It was for an export truck.

the truck has an air pump. The rear brakes on closer examination are hydraulic. I have heard people say something like air over hydraulic. This is definitely something new to me.

Bryce, your truck may have a vacuum booster for the brakes which works off engine vacuum. What does your air pump look like?

This is a picture I found on line, this is the type grill and front end that my dads 1951 L-180 had.
Does anyone know when, what, why, they made the change?

They are both 1951 "L" trucks. The difference is the body size. When they jumped to the 185 size. it is a fair amount taller. The guy I bought mt truck from has a R 180. It is much shorter, has a green diamond 220 99hp. engine. I kinda wish I bought that truck. You can get a fair amount of parts for it through a lot of the parts houses. Once you jump up into the red diamond the parts are a lot rarer.

I haven't been able to see what the air pump looks like. At the moment it is grease oil and a lot of cotton tree cotton all over it.
