I’ve never seen anyone open the cylinder cocks AFTER the engine was started. The idea is to open them all, crank the engine over to make sure there’s no liquid in the cylinder. Then close them all and start the engine. Somebody got it backward. Never seen HEP in a B unit before.
Well they are the cylinder test cocks which should be opened when turning over the engine by hand when it has been standing still for some length time to see if any water comes out from condensation or an actual leak which could hydraulic and damage a piston or bend a connecting rod. = I have started 100's and run them using that principle, and after that just crank the engine over a couple of revs and stop, then tighten up the cocks for full compression to start for service. = Why he is opening them when running is just madness and dangerous.
@@70RJB That particular prime mover blew out alot of condensation while turning it over prior to start up. And I was afraid that I hadn't gotten it all out yet. So I cracked them all just to ensure all was alright. I've done it before. A couple of mentors I've had prior to this have told me you can fire the engine and even have it running with all test cocks open. These men worked all over from the Rock Island to the CB&Q and D&RGW. So I don't see what the problem is.
@@70RJB I don't think it is dangerous to open them when the engine is running but ALL of the condensation should be removed through the test cocks by turning it over with the fuel pump relay turned OFF BEFORE firing up the engine. Otherwise there is a risk of damaging the engine due to hydrostatic pressure.
@@rearspeaker6364 More alike than you might think. Both GM; both two stroke diesel. If that genset is a 71 series, its cylinders are exactly half the bore and half the stroke of the 567 "big brother."
@@mattlf9120 the prime mover doesnt shut off. Some of ours have hot start which is a tiny diesel motor that circulates the water and heats it. The hot spot allows the prime mover shut down to conserve fuel
I haven't seen a engine that big, besides on the ship im stationed on. That's awesome, thanks for the video.
I believe its 561 ci per cylinder

Maybe that's why their F units always broken down
That looks WAY too clean from what I remember of F units on the CNW!
Nice video bro!!!!
Thanks man
Interesting - it has a 71 or 92 series as well - is that to pump up the air or run a generator to start the main engine?
By the look and shape of the valve covers it is an 8V-92
What is the turning of the handles for?

For what is the small Engine used?
It provides electricity for the passenger cars
What was the other V-8 engine for because I never seen it until now.
probably for HEP (power for lights heating etc) for the passenger creature comforts
What's with the Detroit engine?
"Hotel" power. Electric current for the passenger cars.
Why is there an 8v92 detroit diesel in there
Head end power for passenger cars. It's a genset.
@@silicon212 Usually running near max RPM and LOUD!!
@@waynewagner395 its competing with big brother nearby!

@@ckuehncnwhsyt Correct!! the EMD is a mutant sized version of the detroit diesel inline and vee series engines.
Is the radiator full up on antifreeze?
They run on water with dye so you can see the level of the water
@@JaysPrints What color is the dye?
@@bulgingbattery2050 the dye in ours is a light pink
What happens when it's -35°F
