Sure, I mid WWII JD Adams designed/manufactured the 1944-46 Adams No. 311, with an International Harvester TD9 gas over diesel The tandem axles were preferred over the single axles because the single axles had a tendency to bounced at higher speeds. Tandem axles also maintain a better and consistent traction to the ground. Bouncing on long stretches made washboards in roads and runways.

The single axles Motor Graders did find a smaller niche in the market. Single axles would turn 🤣😂🤣 sharper (🤔 okay let us just say they had a tighter turning radius. An astounding 37.5 acres to turn around and not the traditional 40 acres 😉) They ruled in smaller and tighter areas, eventually the single axle found themselves in maintaining military bases and civilization municipalities. As an initiative equipment was given or sold to (at extremely low rates) State or boroughs that became incorporated.
 
In early WWI & WWII Military contracts were up for bid. Lots of industries had to build and fast. J: D. Adams, R. G. LeTourneau, David Boyd and his brothers (Galion Iron Works Co. c. 1907), Case, Holt and Best (Caterpillar), International Harvester and many many other well known equipment owners knew and would often bid agents one another on Military contracts. J. D. Adams and R. G. LeTourneau were friends through out WWI & WWII, Adams was eventually bought out by LeTourneau 🤔 in 1960.* *Yes it's heavy equipment there's always a caveat. Adams had previous contracts with the U.S. Army Corps of Engineers which LeTourneau honored and which still carried the Adams name.I have a picture of the last Adams ever made. Inspection/Manufacturer date 2/61.

So as we have seen here; Military contracts were a little behind the curve which by late 1945 early 1946 gave way to a gluttony of Military Surplus. Between Post WWII and Pre Stathood Alaska (1959) and Hawaii (1960) were found to be of vital national and global interest and seriously lacked infrastructure. Municipalities in Hawaii and especially Alaska were in desperate need of road building equipment and people to operate them.  

In 1946, my Adams was sold to the Territory of Alaska and lived most of its professional life on the Keni Peninsula between Girdwood and Homer as ARC 971. Before DOT April 1st 1967, Alaska had the State equivalent called ARC (Alaska Road Commission). After Statehood in 1959, the 311 Adams had to be transferred from The Territory of Alaska to the State of Akaska so it had to be titled.
In 1960 was sold into Civilian life and spent several years in the glacial silt of Kasilof and then in the Matanuska-Susitna Valley.

On Adams the EOA35 (Engine Over Axle) were a married transfer case for single axles with Hi/Lo gear box. My 311's EOA35 was manufactured by Pacific Enterprises Los Angeles, (23) Calif. "👀 🤣🤣 address" the EOA50 were for tandem axles. The transmission and final drives on the 311 were from the 1937-1948 Oliver 80 Standard.


Might I digress 🤦‍.

 
 

Nearly lost it all. 😮 so I'll post more pictures here.
 
 
 

Thank you Dan. I did not even know I wanted to know that. A whole bunch of the emoji things. Hopefully people find this since you took time to get this information save.Thanks again.

May your pony always start. May the ground stays frozen so no sinking into the mud. Or what ever it takes to make you happy smoothing the trail for those that come after.

And to Mark may the pieces of the correct pulling/pushing gear appear to make your job possible without endangering yourself.

Yes, I was aware of the preferred tandem arrangement. There were a few "similar" machines to yours around here...like the Austin Western Pacers which were all wheel drive, though. Interesting machines. There is a guy around here that owns and still runs a Caterpillar No.11 without tandem drive and another with the tandem drive. Both have wing plows and grade roads in the summer (minus the wing plows though) and plow in the winter...limited use though. Nice to see on occasion when they're out. Thanks for the pictures and history.

Just to be accurate..one of the older cats I spoke of with the single axle was a No. 10.

FatDan thanks for the info interesting read

Cat attempted pulling wheel hub today. 50 tons of pressure and heat but it wouldn't go. The mechanic even hit the back of the hydraulic cylinder with a maul.

What worked for me on a very tight 12 grader wheel was I used the largest bar type puller I had, tightened as much as I could without breaking it and leaving it for about a week, it was in a sunny spot so the wheel could warm up during the day then cool at night.
I would snug it up daily, after about a week I came out to check in the morning and it was free, figured it was the heating and cooling along with the pulling.
Seems like there is two choices with some of those wheels, super tight or loose and all busted up.

May need a bigger ram. 100ton?
I do like Josh's method though.
