Caterpillar D8 8R WW-II era bulldozer (1943) working

[jserra17]

Fun trivia fact: This dozer has a cable operated blade. In WWII, hydraulic systems were a new technology. Among the first applications: The aircraft elevators on US aircraft carriers. Also among the first applications, the movable stage at Radio City Music Hall - it could raise, lower, tilt and rotate. The technology was so important that armed military guards were posted in the mechanical area under the stage, 24/7 for the duration of the war.

i love running old cabel dozers the 14a d8 and d9s are the best ,better than the new ones/

[sterob666]

how come it needs 2 opperators?

[rackasaurus]

I'm not really sure what's going on in this particular video, but when I was in the Seabees I learned that back during the War that second seat was usually manned by a rifleman who provided protection for the operator. Most of the heavy equipment that the Seabees used on the islands had that second seat on them. Like our motto states - "We Build. We Fight". Sometimes simultaneously. That's why they call us "The Fighting Seabees". Hope this helps with your question.

So was this D8 actually used in WW-II?

[darensmiles4]

I imagine that machine has paid for itself over a thousand times in its life time.

How'd you like to try lazer grading with this old girl???

[tom2024]

i respect the oldtimers i would wanna have to run the old shit

[localcrew]

Plus, you wouldn't oil the tracks. Maybe drive it through a puddle. Or over an idiot. Thanks for playing!

[localcrew]

I noticed. It's the tracks. They're too dang tight. And yes, the "winch", as you call it, is also screaming. Only it's not a winch. It's a PCU. Power Control Unit. Made by LeTourneau. Anything else?

[TheDieselDr]

Have you ever read R.J LeTourneau's book Mover of Men and Mountains I just finished it wow what a guy!!

[localcrew]

No but I've heard of it. Dude was a one of a kind. One of the world's great inventors, that's for sure. Ever heard of a book called "Moving the Earth"? It's long out of print but copies are out there. It's old-school earthmoving. You should check it out if you can find one.

[TheDieselDr]

Don't LeTourneau make prostetic limbs and stuff now too???? his book details alot of aspects of his life how he went broke multiple times but still kept on truckin' or should I say scrapin' and he sold one of his machines to Holt witch is now Caterpillar. His electric drive heavy machines revolutionised large earthmaving equip. It is a real good book and I recomend reading it, I'll try to find a copy of the book you mentioned,, Thanks, TheDieselDoctor.

[localcrew]

Don't know about the prosthetics. I'm from Louisville Kentucky.

[localcrew]

Dang! Loosen those tracks! They're screaming for their lawyer.

[drugaria]

you probably didn't notice but it's the winch crying for oil not the tracks

[flyingscrapyard]

Nice old tractor. Yours?
