I think Daimler came a lot later. First came Roger Penske in 1988, buying a majority interest from GM. I think the first DDEC came out on the 92s before the series 60, maybe about '85.

Only real experience I had with 2 stroke Detroit was a couple retired greyhound busses we had at Opryland hotel when I worked there and our shop foreman rebuilt those and story was they may have been slightly hotter than should have been as he was retired navy mechanic and those were his baby’s lol they would definitely clear 100 in a hurry

We saw the DDECII and DDECIII systems on the 190 ton Haulpak trucks that went into the Centrailia mine in about 1994 or 1995. I never worked on those monsters but did get a little bit of an introduction to the DDEC system when I went to a school for the 50 ton Haulpak trucks in 1992. The instructors had some graphics on display to show the data logging and diagnostics inherent in the systems. Would have like to learned more but the trucks I was going to work on had K series Cummins in them. I didn't see another system like DDEC until I went to work for the Cat dealer in 2005.

If i remember correctly, i saw one of the first series 60’s with a JD logo here and there on some castings. I was told by the salesman that jd had done some of the foundry work. Somebody correct me if i’m wrong

Engine blocks and heads are difficult to cast, and Deere does a good job. Deere was actively looking for outside block work in the late '80's and early '90's. Those early blocks were machined by CBS Boring in Frasier, MI.

I believe the original work started in the late '70's. I later worked for the man who did most of the airflow development work on the cylinder head in '81 to '83.

The double zero engine was such a turd by the time the Silver arrived the damage was done. Detroit held
30% of on highway share, by 87 3 to 5%. Good link to read below.

A friend own this two story falcon a 79, he shot through 3 double OO's in the first 200,000 before
Emerson Diesel Seattle replaced the third with a Silver. Which ran 400,000 before he sold the truck.
He never owned another Detroit.

I bobtailed/drove one of those from the dealership to my shop to repair some transport damage, (paint) when new back in 79. That truck about scared the B'Geezus out of me the first sharp right turn out of the lot onto the state highway I was entering. Thought the damned thing was gonna roll over right there in the street. You can see in the above photo the "lean" the air ride cabs had on them and at the time I was used to Mack Camelback, or Hendrickson spring suspension, and rigid mounted cabs only.

The short time I worked at the GMC Trucks dealership I was swinging the shop crane replacing those with the "Silver" series. Most were higher in power settings too and IIRC all were aftercooled. Warranty replacements had kits supplied for some additional plumbing but I don't remember what it was for.

If I wasn't changing the "92" series engines, it was the 5.7, and 6.2ltr engines in the pickups..... GM still had a lot to learn in those days it seemed.

The 4.5, and 6.8ltr. Deere engines I had in generator service were tough to keep a head gasket in until the head was planed. Seems the Brazilian foundry didn't "season" the castings correctly and they warped shortly after being placed into service. I did three of the 6.8ltr, and two of the 4.5ltr engines myself as they would get to pushing oil out at the head to block seal. No problems after the heads were planed level.

One of the biggest problems with the deere engines(green or yellow) that we had, was when they took the asbestos out of the head gaskets. It was tough to get the head to seal properly no matter what you did. They would usually weep coolant. Numerous solutions were tried. Some worked-some didn’t

I resent that! Both these machines are sitting on my shop floor.
