12.7 detroit questions about parts that will work on my dd111?

My DDEC 111 I had overhauled at 960,000 for no reason, other than I was running back and forth to Alaska from all over the lower 48 and figured it eventually had to go down. I did change the oil regularly but didn't do the overhead that often. I took it to stewart and stevens in lubbock and had it done, and they checked the bull gears, but didn't replace them.
They actually told me when they pulled the valve train, they seriously doubted it would need them replaced, because it was in such good shape. The inframe did come with all new valve train components though.
It was and still is a good cheap engine to run, it just doesn't have the torque I need for what I do up here. If I had to go back to runningthe lower 48, I would be sitting in it though.

 

Well a true 1850 would get it, but even the detroit reps could never get one to work up here spending months trying. Detroit themselves finally threw in the towel and put a pittsburg box on one test truck, but it didn't last much longer. lol

You can get by with them I know of a couple that used them for a few months to get started, one changed out his gears to 433 to make it work for him.
Another thing is they do not like the cold, and will actually make you think the rods are knocking when it gets below 60 below, for some reason a few quarts of tranny oil in the fuel will quiet them back back to normal.

 

Like I said, detroit spent a lot of bucks and time trying to get them to compete, she didn't fly. You can get by, but that is all. These new detroits are pulling fairly well, actually doing as good as the cummins, and better on fuel. A few of the OO's have gone to either freightliner or star, but not a lot of miles on them either yet, The first one I know of that bought one, bragged on it pretty good,but they had to put him a new engine in pretty quick too. lol His brother bought one the same time, and when he decided to sell had a hard time getting rid of it.
But the new cummins are not getting a lot of miles on them either.
