Default Stewart and Stevenson - Help Identifying Generator

Can anyone provide some information about this generator. How much would this weigh? Any tricks to moving a generator without a forklift?

Looks like a 2-53 GM diesel and perhaps a 20KW 1800rpm generator head? I would guess that it weighs around 2500lbs setup like that on the skid it is on. Perhaps weld a few tabs on the corners and use a jack to lift the generator up. Once you can get a few pipes underneath you can roll it without too much trouble. Do you have to move it very far, or lift it? Some rollers, timbers and maybe a pallet jack will help you out greatly. A come along to winch it up an incline on some timbers would be a good idea.

17kw 3phase 60cy 120-208v 17kw 59amps is what I can read. It's actually resting on about 3 to 4 ft high stack of cinder blocks. Way more lbs than I was hoping for.

Sounds like it's about high enough to back a pickup truck up to it and with a pry bar, couple planks, and few pieces of pipe roll it into the bed.
I like Chris's weight estimation, I have and have moved several 2-53 generators.

What's the rest of the story?

I would sure like to have it.

Things to remember-

If it starts to fall, get out of the way and let it do so.

It is easy to injure or lose a finger when you are lifting and shimming with a pry bar.

If I had to move that guy I would round up 4 automotive floor Jack's, knock out the corner blocks and use the floor Jack's to raise it up enough to get all the blocks out from under it. The lower it down on some 2" or 3" pipes, or you could use some wood timbers if they are pretty round. Then use a chainfall, come along, a winch, or even your truck to pull it. It will move nicely on a set of pipes. Use your truck to anchor the chainfall if needed. I would not try to load it into the back of a pickup, it's too high to winch up into. Try use a utility trailer or car hauler with a good set ramps which is lower and you will also have a place where you can attach the winch to, to get the unit pulled up onto the trailer. If needed lay down a couple pieces of plywood over the ramp surfaces to make it easier to roll across them. I've moved a quite a few pieces of machinery and this way works pretty good. If the framework had beveled edges you could probably just drag along the ground, but the way it is it will want to dig in. Just another idea.

Its a 2-53. Looks like it is operational. In addition to making power it also produces a few decibels at speed. AL

Someone asked for the story behind it. My late grandfather was a commercial fisherman and this generator is located at his home for use during hurricanes. I am not sure if it was removed from one of his boats or purchased specifically for home use. Below is a link to some of the boats. The first picture was taken in Fort Lauderdale, FL where he purchased a boat and carried it back to North Carolina.

As I understand it, the generator was brought in on the back of a towtruck and then placed on the blocks.

It is an old one. It has been a few decades since I have seen a phone number listed like the one on the name plate.

Thanks for the boat pictures and background. Neat seeing the old car in the boat. Did he drive the car down to FL and the boat home?

Numerous ways to move something heavy and even more opinions...
Main thing is take it slow and easy and stop to reevaluate, or don't even start, if you're not comfortable with it.

What's your plan for the generator?

S&S marketed substantially towards the marine market. Since this one has a radiator, it was not set up for marine applications (they're cooled by heat exchanger via seawater)... but they're popular in the seaside markets none the less.

And yes, it's extremely efficient at turning diesel fuel into noise...

But a great generator... I'd take it!!!

Noise?? No.... MUSIC!

Though certainly the three's, sixes, and twelves are much more musical than are the two's, fours, and eights.

I think a Detroit Diesel 3-53 is the loudest engine per horsepower that I know of.

I would guess close to 3000 pounds and also it's WAAAAAAAYYYYYYYY too heavy for anything short of a 1 ton pickup. I hauled a 2-71 railroad set in my 3/4 ton, supposedly they weigh 2200 pounds, and it was kinda scary. If you try this in a 1/2 ton truck you'll damage something and you be lucky if it's only the truck.

The 2-71 is heavier.

I've hauled a 2-53 generator like this in the back of a 3/4 ton and it fit real nice and not anywhere close to overloaded.
Also hauled a 4-53 generator in bed of same truck and that was a load...

The generator was successfully moved with a forklift and a trailer. Thank you for the advice. Does the tank need to be mounted under the generator? Is a bank of batteries required to start the generator? How would I determine the CCA?

The overall goal is to connect it to the house for outages. It would be nice to convert to single phase.

Fuel tank can be most anywhere you want, just not real far below the engine so pump doesn't have to work real hard to lift it.

One Group 31 battery would be perfect, assuming 12V, or two of them for 24V.

You need to see how many leads come out of generator, at the generator.
If a whole bunch it is likely you can reconfigure for single phase only. If only 3 or 6 leads (or?) it is probably 3 phase only. A generator/motor shop can be helpful here if you don't have any literature for the generator.

Unless your house has unusually high electrical loads you can just use 2 leads of the three for your single phase needs. This makes the generator unbalanced and you only can pull 2/3 or little less of the name plate KVA. Not ideal but workable if your not taxing the generator heavily. I'm running my house on a 2-53 generator, loading single phase on 3 phase generator, plan to have it rewired for single phase only eventually, in my case requires digging into the windings to reconnect... or a full rewind.

When I removed it from the previous electrical panel it was wired as you suggested with two leads for single phase.

Is there a recommended procedure for starting a generator like this that has been sitting up several years? Replace fuel filter, air filter, oil, etc?
