Holy crap! The parts are huge compared to a car size engine. Thanks for sharing the pics!

 

Thanks for posting, really neat to see the huge size of these components

 

When my little brother was in school learning to be a diesel mechanic and Ooooing and Aaaahing over the cool size of everything, he was a teenager. Now in his mid fiftys he comes home grumbling about the size and weight of everything he has to lift and work with. If I had it to do over again, I would look at the size of the tools I would be working with and choose my career accordingly. Big tools=big work.

 

= BIG MONEY!!!

 

thats what was being said when I snapped the picture, lolz

 

*IF* you can get and KEEP a job in a good shop.

 

I work in a truck stop, and all last summer and fall these trucks would all pull in together and leave together. We got to talking with them and all they'd say was they were testing new engines. They'd tell us how awesome they were, but couldn't go into any specifics. Well just the other day they came in and said that the secret was out. They picked up a magazine and showed us what they were running. Detroit Diesel DD15 prototypes These guys would take fully loaded trailers up the steep side of the mountain, Turn around at the top, drive to the bottom and go back up. They'd do this all night 8 hours strait. These guys just abused these trucks. I'm very impressed at what they can do. Not to mention they said the average rebuild time has been extended from 800K to 1.2 million miles.

 

Detroit is putting the turbo to good use.


Hell, the Cummins ISX oil change intervals were 500,000 miles. but now it doesnt meet emissions standards, so off with it. . .

 

Small stuff. I work in a heavy duty shop too, and that stuff ain't that big. I don't have any engine pics though.
