Hey folks, New to the forum. I figured my latest project might be of some interest to yall. I recently bought an old V1702 4cyl diesel off of a buddy of mine. It was originally in a bobcat skid loader. It was missing some parts and needed some attention. Hasnt been run in years. I got a flywheel, bell housing, throttle plate, shutoff plate, lift pump, and solenoid. It runs like a champ now. I welded an engine stand with some 1-inch steel tubing. I had an idea after seeing the aftermath of Hurricane Helene and decided to make a generator. I did some rithmetic and research and decided that 15kw should be plenty to run all my home appliances. I have been working on getting some engine accessories like switches, gauges, sensors, etc. My goal is to have a robust, self regulating generator on a budget. I am working on finding a generator head and a governer to regulate the engine speed and therefore regulate the AC frequency. If I opt out of that then the loaded frequency will be lower than it would be unloaded. Any advise or critiques are welcomed.

possible option.....
trade the engine for a good generator ?
If the engine came FROM a Bobcat, it might be worth some serious coins as a replacement ?

But where’s the fun in that
. I did look into this and apparently the v1702 was a less powerful engine than the v2203. And most people just drop the 2203 in place of the v1702. It would not be worth it for me to sell it and try to find a good 15kw generatorRCW

What is the HP rating of the v1702?
Sufficient to drive a 15kW generator?
Sounds like you’ve researched this quite a bit.
. Engine control seem to be something to look out for when converting uses to a generator or compressor from an an engine that was designed for a skid steer.
Look forward to your project, and certainly hope you’ll document it here!

I'm all for' bodging' ! but.. just thought I'd give you an option before you get 3/4 way through and 'wouldashouldacoulda' is spoken....
engine is 35-40HP, so should power the genny fine.

Might not be as much of a challenge as you’re looking for, or maybe more $ than you’re looking to spend, but you could buy a PTO driven generator and work out a driveline to mate it to the engine. I’ve been quite impressed by my 16kW IMD.
I built a 10KW genset with a Yanmar 3TA72 22HP engine and a generator I bought from Norther Hydraulics. The biggest problem I had was the coupling to connect the engine and generator, but I finally found one that works quite well.
I've used it three times since I finished it up a couple of years ago, and it works perfectly, powers anything in the house, well, A/C, electric range, etc. Burns a couple of quarts of fuel an hour running at 3600 RPM.
Was a fun project, so I would say to go for it.

All my gennies are of the "small variety" (less than 6.5kw) so I don't have any real experience with larger ones, but it sounds like a cool project.
I would definitely make it "towable" like @dlsmith did. (Very nice job BTW sir!
)
I also like that exhaust cap to keep rain out.
One thing that comes to mind is that I have heard that the newer electronics do not 'work and play well " with erratic spikes, so finding some way of cleaning things up (electrically speaking) is a must.
There are lots of talented people here who, "Have forgotten more about electricity than I ever knew", that are willing to give ideas, so keep us posted and remember......Pics, or it didn't happen.

Most/many generators rated at 15 kW or so are designed to run at 3600 RPM for 60 cycles because the engines they are usually run with put out near max HP at that RPM.
I expect your 4CYL diesel does not run that high an RPM?? What are its specs?? I THINK that many/some of PTO driven generators have gear-up or Belt-up attachments or are designed to run at lower RPMS. One way or another you need some MatchMaking here. Or you may end up with 30 cycle AC..
Let us know what you find out...
Some good info HERE

Also, the springs and axle are mounted on a subframe that comes off with six bolts so it can be set on a slab, and it has vibration dampening pads on all four corners of the frame to keep it from moving around.
Hi, What RPM does this run at? 3600 or 1800. Wondering about the question of (usually slower rpm) small diesels for a Generator.
You didn't read all of my post I guess:

Generators can be either a 2 pole design or a 4 pole design (there are other pole speeds just like electric motors). If the rotor of the 2 pole design is turned at 3600 RPM (plus the slip) you get 60 Hz out of the stator leads. If the rotor of the 4 pole design is turned at 1800 RPM (plus the slip) you get 60 Hz out of the stator leads.
I assume you are questioning if an engine that cannot get above (say) 1900 RPM can generate 60 Hz power and the answer is yes, if connected to the correct generator. If I misunderstood your asking, I apologize for the needless post.

I just learned about PTO generators. Did a quick search and came up with this one my 1880 can handle. Have no idea what is good or bad on pto generators. I have 2 Honda gas generators that work great and trust.
Good luck on your project. Looks interesting but expensive.
