Detroit Diesels on Song.

We had 2 trucks w 6V 92 and I don’t remember them being horrible in the cab compared to Industrial equipment
 
Back in the 70s had a church memeber tell me a friend of his died when the 2 wheeled scrapper he was driving came loose someway and flipped over!
The joke on the fuel island in the 70s was you always knew the truck had a detroit in it when the driver told you to "Fill it up with oil and check the fuel!" :laughing:
Rumor was one of the local excavation companys had either a 12 or 16-71 in one of their trucks that smoked the tires hauling a D-9 all the way up 9 mile hill west of ALb
 
I swear these would have been muffled in use. I remember watching the Terex scrapers work as a kid and they were loud but not that loud.

These "restored" machines are running straight pipes and I couldn't see any earmuffs, most operators were only wearing cowboy hats.
 
Those sound like 53 series, 6v's and 8v's. 71's and 92's weren't near as bad however still louder than the Cat's and Cummins of the day. We ran them in shrimp boats and the supply tugs I worked on had them for generators, crew boats had them for main propulsion. Some of those 12v's and 16v's could really hit the high notes :lmao:. Took me years to learn how to sleep without a Jimmy Diesel running near by.

No operator today has the arm strength to run any of those for 8+ hours per day.

My first truck I bought in 88 was a 81 International cabover, 350 Cummins 9 speed with leaf springs and manual steering .

my arms and chest ached for the first three months , but after that I had rock hard abs and nice forearms .
 
Check out the seat in a 1922 patented drag line in a field near me

All that comfort and noise too.

It was incredibly loud, I couldn't stay long watching.
These things were common before ear protection really existed!

our family had commercial boats at one point of time
we had one of these as a main power in one boat, I can still hear the scream it made in the engine room:laughing:
 
I saw my friends dad who I am also friends with the other day. He said guess what I got the other day. (This guy has more old iron and big iron than anyone I have ever known, so I honestly had no guess). He said I got a 12v71 and Im going to pull the 60 series out of my dumptruck and put it in there. I believe he will too this is the same guy that built a Chevette Diesel Allis Chalmers CA. He has the ability to build something from nothing somehow. I asked if he was going to put mufflers on it and he laughed and said “I think I’ll straight pipe it.

First truck I ever drove with PS was a new Pete in 88. Prior to that was a 72 Pete without PS and no brakes on steer axle. And wood floor cab. I loved that 72.
 
In Biloxi in 1995, one of the other O/O’s hauling stuff from the port had a conventional , I don’t remember the brand but I remember it didn’t have brakes on the steer axle .
Was weird being to see right the kingpins through the holes in the alcoas .

Yeah

I’m not sure what year .

It would be scary bobtailing in a tractor with no brakes on the steer axle .

It was scary bobtailing in the rain in a 80s tractor WITH brakes on the steers .
Bob tailing in the rain , especially in a cabover , required alot of caution .


In the early 90s they started using a proportional valve to reduce the brakes on the drive axles if you didn’t have trailer air connected .
