Lately I've been thinking more and more about a diesel cogeneration setup for my shop. I've always wanted a lister(oid), but, that just seems like too much work right now with their legal status, and the fact that I'd basically have to rebuild the engine before I can use it. And build a generator, of course. I would like to buy something nearly turn-key ready.
So I went looking around for small water cooled diesel generators and it seems there isn't much you can touch south of $5-10,000 commercially available. The used market is pretty hit and miss.
Then comes in my buddy craigslist. I found a 2004 model Genie light tower with a 3 cylinder Kuboata D1105 engine running at 1800 RPM powering an unkown brushless 6kw gen head. It only has 240 hours on it and I can get it for 2 grand. I don't need the 30' 4kw light tower, but I could sure have some fun with the neighbors...
What do you think about this engine/generator combo for long running cogen use? It seems to be built for heavy use. I would think the engine alone is worth $1500 or more, if it only has 240 hours, am I right? That should be just broken in. Can anyone tell me more about the Kubota D1105 engine? How many hours can it rack up at 1800 RPM before it needs an overhaul?
My other option would be to try and build basically the same thing with the 2 cylinder Yanmar from Surplus Center, but I might have to run that engine faster than 1800 RPM, and I'd likely spend close to 2 grand (and a couple years) on the project. The 3 cyl Kubota seems like a much better prime mover - and I don't even have to load it into my truck, it's already on wheels, with a 30 gallon tank!
Does anybody know of ANY other option for a near turn key, water cooled diesel generator new or low hours in the 3-6kw range, for less than 3 grand or so?
