So actually - I'm torn between laughing at the dude strolling next to the thing yelling in dutch or german or whatever while the tractor moves slower than the speed of smell...
...and....
...thinking that that is one of the cooler motor-sports vids I've seen in a long time!

I'm guessing that this is old enough tech to predate even the mechanical old-timers here...

That first one was pretty cool. Although I think those were diesel, steam is where it's at for power. Weight equals traction, and when you've got a couple thousand ft. lbs. of torque under you, nothing can stop it.

As a kid, I used to love going to steam shows. But most of the old timers are gone now and the tractors have all but disappeared.

Nah.... you just don't hang out with enough big diesels. Comparing a massive steam engine powered tractor to a small diesel tractor is not much of a comparison.
-
I liked both sets of movies, but that old steam tractor was just awesome.
-
You're right, Drew. The bigger steam tractors can easily produce over 3000 ft. lbs. of torque at 100 RPM or less. It really is no comparison :) But I was considering the cool factor as well. I know you're a little biased..lol
-
Always like to see external combustion tractors.Max torque at zero rpm's is plain cool.
-
Guess the HP and torque curves won't meet @ 5200 rpm!

Volvo BM made a tractor named Viktor that had highest
torque at idle this is the forest version called Bamse

Nice to be retired so i dont have to work with this any more

My Dads old Farmall F12, with a cracked exhaust manifold, sounds just like that Volvo. Don't have a tach hooked to it, but I swear that thing will lug down to a couple hundred RPM and still pull fine. I know diesels are great for torque, but unless you keep them in a heated garage in the winter, they are a MAJOR pain to get started, at least when they're old like those in the videos. Even worse when you have one runaway from you.

Richard, the calculation is the same. The engine just happens to top out at a max rpm so the hp/torque curve looks different.
This is why my 10,320cubic inch engines are only rated at 2,000hp :-)
I can say from watching and testing with a load cell, that our boat, floating with the two engines at full rack can generate 79,800 lbs of pull against a dead weight on the dock. (We are rated at over 80k but it was 102 degrees that day, so I suspect that was the issue).

Dough we have a couple of old Volvo Diesel tractors
from the 60s
We use electrical heaters put in one of the coreplug
holes (all cars around here have it Diesel or gas)
can be minus 35-40 C here for weeks in january
Its worse when you have it deep in the forest.
You have to start the day with making a fire under
the oilpan :D
We have an old 1942 Oliver Cletrack modified for
logging work gas powered magneto ign 6 volts
i have started it when it was -38C with the starter
40 we had to help it with the handcrank

My babies here on the boat:

Thats a valvecover 8).Does offenhauser make finned
covers for that ;D.3 rockers 2 moves together and
3 valves on one rocker?? am i halusinating or is it
a twostroke diesel or what?
-
EMD 16-645-E2 engines. 2Strokes, the only GM product I willingly work on. Probably my favorite engine of all time.... it is just so well designed to be serviced in place. I feel we can sail around the world with just a few parts.
4 exhaust valves per cylinder, no intake valves. The center spring is for the injector which is still controlled by a manual rack because tier 0 is the best tier.....
The rockers you see have three springs each (so 6 exhaust springs for four valves). The center spring is a stabilizer for the bridge. The excessive clicking you hear in the video are from the rockers. Despite being an overhead roller cam the rockers have what we call "poppers" on the valve tip end. They are essentially hydraulic lifters of sorts and with a lil rpm they fill with oil and take up valve lash. Of course these engines currently have 50,000 hours since the last overhaul so they don't really pump up until they've been running for awhile. Engines themselves were installed in place in 1976 and have only had overhauls every once in awhile, typically dictated by lube oil consumption. With a fresh build they will consume 7 gallons of lube oil a day each, we typically rebuild them when they start consuming 40+ gallons a day. Seems like a lot, but at full steam we burn upwards of 4,000 gallons of #2 a day. Realistically at cruise we burn 2500-3500 depending on what we are towing.
and yeah, doing a valve adjustment on a V16 when you have to set the gap on 7 things per cylinder is a little tedious.
intake ports look a little like this:

I just did the valve cover seals, they don't use gaskets, they use a 16 ft long rubber cord... doesn't seem like a big deal until you do 8 of them :P

I'll bet Drew it's a stone bitch to set the valves while hot and running! LOL :)
EMD = GM's Electro-Motive Division in LaGrange, IL near my home. They have made locomotive and ship engines for many decades at this sprawling plant. I wonder if yours were built here or at another plant. Any I.D. plate on yours as to where built?
-
Setting the valves REALLY isn't that bad (Nobody sets valves with the engine running). We always set the engines cold. It's just easier. Funny thing about these, when you've been towing really hard and you let them cool off then shut them down, they will pop and crack as they settle down to ambient temperature. First time I heard a liner pop loudly it scared the crap out of me.
A plate is welded to the side of the engine dictating what happens when for crankshaft degrees. This way you can set the injector and valves while you roll the engine over. It's very easy to roll the engine over by hand with just a prybar on the flywheel teeth. Funny tho, when working on a Caterpillar you jot down notes in a laptop computer. When working on a large Cummins, you take a notepad. When working on an EMD, you dip your finger in some of the jet black lube oil that leaks from everywhere and write on the side of the block.
Both of these engines were built there at La Grange.
I should be there April 18-22 at the factory.
Anyway, this is why I ask questions like "What do yall torque spark plugs to with aluminum heads?" I'm used to everything needing to be perfectly blue printed as these engines essentially must survive an 8 year long dyno pull.

I was aboard a tugboat one time to change the
pipes for fire extinguising. It had a V12 Fourstroke
there was some spare rockerarms on the floor
about 20 inch long with roller tip 2 inch roller.
And 2 mother of all turbos. inlet on the turbo
was i gues 20-25 inches if not bigger no filter
no screen looked like it could suck me in with
welding machine and everything if they had started
it up. Old run down tug with a rowdy crew
My boss said to me the only thing missing
is a parrot on the shoulder and a wooden leg ;D ;D
lets se if i get any payment from this gang
-
Uh, maybe cash in advance? Hope you get it.
-
Nice Heo!!!
Yeah, first time you see some stuff it seems a lil weird. Like watching a Chief on a dredge with Sulzer engines dump 5 gallon buckets of walnut shells into the engine while running WOT to clean the turbo and liners.
Tugs are a lot more civil than when I started. Back then the crews were all convicts that were unemployable anywhere else.
Your description of that engine reminds me of a MAK engine.
This one was V12, 7200hp at 400rpms if I recall (it's been nearly a decade). Turbo is in the backround.

ohh found this video of a smaller boat I was Chief on, circa 2007. The Captain told me to "get all the power you can out of her" So I turned the rpm's and fuel up a "tiny bit." These were Detroit 2 stroke, 16v149 engines. They are like mini emd's, they were amazing in their NPG's (noise per gallon).

Yikes! 95,000 ft-lbs of torque!?!

That engine ran a pump that pumped mud through a 36inch diameter pipeline 8 miles. Any more than that are we needed a booster pump.
Was on a job with 60,000ft of pipeline (same diameter). I remember vaguely that it took 20-30 minutes to flush the line. Had an engine randomly shut down one time and all that mud solidified in the pipeline (which was on the bottom of the seafloor 50ft down). Was the worst month of my life :P
Nice boats Landlubberatsea! anchor handling is tough work (for those paying attention, my boats bollard pull is 40 tons. LandLubbers boat is rated at 297 ton pull, consider the forces of a floating boat exerting that much on something)
This is my current ride:

For comparison, the boat is 128ft long

Didn't mean to take over the cool steam engine thread..... I get excited about big machinery.

Drew that engine look wery much like i remember it
its 25 years ago now .They towed barges with timber
from russia over the baltic sea to the lokal paper mill
and was grounded after a safety inspection.
Not alowed to leave harbour before the fire water pipes
was changed out. Hot as H...Dieselfumes, probably
been leaking since 1963,cramped spaces, good thing
the pirates brought us COLD german beers in a never
ending suply ;D I had to call my wife to pick me and
my boss up drunk late att night in the harbour ;D ;D ;D

No problem here - this stuff is the same kind of cool to me... :-)

Those Lanz Bulldog tractors in the first video have a 628 cubic inch single cylinder engine. Now that's what I call a thumper!
-
And i thought my AJS 500 was a thumper :-[
-
This old guy has some really cool stuff, about 20 acres of it. The last two video's of the old IHC truck is my kind of stuff ;D
