-What real engines look like-

BargeMonkey · May 03, 2014, 10:35:18 PM

I know its a bit off the "logging-forestry" topic but anyone who loves big bore engines might like this. Theres a pair of 8-710G7 Emd's. Baby engines but still not bad. 2k-hp each at 900RPM. 9-1/16th bore by 11" of stroke. My new home away from home.

sawguy21 · May 03, 2014, 10:47:34 PM

That would run one heck of a mill.

SliverPicker · May 03, 2014, 10:51:14 PM

11671 lb/ft of torque from each engine. Not bad..... :D

Maine logger88 · May 03, 2014, 11:15:11 PM

That's sweet! Are they 2 stroke?

Yup. 4 valves per hole. 1 large unit injector. About 10k per hole for a head-and piston-rod assembly. The emd design close to this came out around 1936. The boats landing on the beach on D-day where emd powered. Most people have never seen 1, alot of them still used in locomotives. If your a detroit guy, you sit in awe just watching one of these run. These are baby's, im used to the 16 and 20cyl versions making 6-7-10k hp combined.

Those are good size engines, but they are baby ones. EMD makes much bigger than that.

sprucebunny · May 04, 2014, 04:24:23 AM

Nice !!

I got a tour of a ship years ago that the engine was taller than my house

Bore was around 36" .

timberlinetree · May 04, 2014, 06:12:50 AM

Must take a lot of oil in the crankcase.

. Neat to see thanks for posting.

So you work on a Tow Boat to support your logging habit? I was on a ship in Texas in the 90's and they had a Fairbanks Morse engine. Huge. I was a 2 cycle and ran 180 RPM . They had a lever that changed the timing and that would reverse the engine and since it was direct drive,the ship. Ran on bunker C. It was an old ship then. Nice pics. I dream vacation would be going through ships and factories.

HiTech · May 04, 2014, 07:14:51 AM

Awesome !!!

Ken · May 04, 2014, 07:24:48 AM

Thanks for posting the pics. How much fuel do they burn and what are you carrying on the barge?

snowstorm · May 04, 2014, 07:31:42 AM

it must have been a big landing craft to use that motor. the smaller ones had 2v 671's. also had a battle setting on the governor that let the motor over turn by quite a lot. dose that tug your on have pod drive?

LeeB · May 04, 2014, 08:17:44 AM

A 16 cylinder version of the same kind of EMD. Not nearly as clean though. Power end for one of three generators on an old drilling rig I used to work on.

thecfarm · May 04, 2014, 08:28:41 AM

That must be loud.

LeeB · May 04, 2014, 08:31:59 AM

Deafening. May have something to do with why I wear hearing aids now. You think? :

petefrom bearswamp · May 04, 2014, 08:41:34 AM

I think EMD stands for Electro Motive (or Motor) Division of GM.
They were a main competitor of the outfit I worked for in the mid 50s, Alco Products Inc formerly the American Locomotive Co. in Schenectady NY.
Alco diesels were 4 stroke so quieter.
EMD did make diesel Electric Locomotives as well as engines maybe still do..
They were instrumental in the demise of Alco as my uncle said why buy a Cadillac locomotive when a Chevy will do.
Bargemonkey where do you run this thing?

Thats a 16-645 -E6 or could even be a 567BC block. Ive been on alot of blown boats. A 16 blown boat is a Cadillac compared to a turbo boat. Fuel use depends, the big boat I was on in the gulf would blow thru 4800 a day at 850rpm, in no weather. Ive seen what they call the "triple 20's" line haul boats in the Mississippi, they use 10-12k a day making 15k hp. I presently work for a company moving stone down in the city, closer to home and no oil barge headaches. These hold 280 gallons of mobil 409 per side, emd's tend to use about .60-.75 gallons of oil per run hour, depending on how tight and maintained they are. A turbo boat will get 25-35k hours to a repower, blown boats can get 60k hours at most. Yeah this supports my logging equipment addiction, worse ways to make a living.

I was chief on a twin 12 cyl Alco boat, the Valentine Moran years ago. I will take an Emd everyday of the week over an Alco. A turbo on an Alco is a nightmare, dont hold up and can be 75k+ every time you do one. They are abojt gone out here. You wanna see something awesome, look up a fairbanks morse 8-1/8 OP engine. The guys who designed this stuff had their acts together.

LeeB · May 04, 2014, 10:13:37 AM

16-645-E8 is correct.

Dave Shepard · May 04, 2014, 10:30:35 AM

The ski area where I used to work had two FB gensets. 1, 200kw. I think the model was FD38. They were 10 cylinder, 20 piston engines making 1,600 hp. I never got to see them run. A friend of mine ran the engines on the Mauna Loa during Vietnam. It had a pair 9 cylinder Nordbergs making 3100. He has a bunch of good stories about the engines on the different ships he was on.

petefrom bearswamp · May 04, 2014, 10:32:21 AM

My uncle told me that quality suffered when Alco was bought by Studebaker Worthington in the 70's.
Sounds a little like the Harley Davidson to AMF debacle.
He spent his entire career with Alco, first in Schenectady, then Auburn NY. Dunkirk NY and in Ohio somewhere.
He retired a disillusioned man as regards the company.
BargeMonkey, regarding a job to support your logging addiction, If I win the lottery I will just keep sawing until the money is spent.

clww · May 04, 2014, 10:35:30 AM

You should see the engines we had on the aircraft carriers, both conventional or nuclear.

BargeMonkey · May 04, 2014, 02:36:11 PM

When you get into the big bore, slow speed, heavy fuel stuff im kinda lost. I took the bare minimum steam for my license. Theres quite a few OP FM ex navy YTB boats still running around, changes your way of thinking.

Dave Shepard · May 04, 2014, 05:51:32 PM

I'm sure you must know about the Wartsila-Sulzer RTA96-C? 108,000 HP, 5,800,000 ft/lbs torque at 102 rpm. ;D

Corley5 · May 04, 2014, 06:05:27 PM

Cool Stuff 8) 8) 8)

loggah · May 08, 2014, 06:14:06 PM

Heres a couple of crankshafts out of 8 cylinder Enterprise diesels we scrapped ,12 inch bore 15 inch stroke,400h.p. at 400 rpm each engine weighed 22 tons. It was a shame to scrap them but the repowered the Mt.Washington with 3508 cats with gearboxes. Don
