I want to build a generator attachment for the Caterpillar to be able to run power tools. I plan to belt drive it off the PTO clutch and bolt it to the bottom of my new front bumper. Firstly, I need a generator that works but the engine doesn't. Plan to use someone else's plan of cutting the engine apart for a main support bearing. So... Does anyone have anything. I have 18 hp engine, so just about any size would work, but looking for at least 10 amps of 120v AC power, but upwards of a 20 amp output would be fine too.

10 amps at 120V...So you are looking for 1200 Watts, more or less? How much does your existing alternator put out? I recall it being 37amps, at 12 volts, so you have about 400 watts on tap already. Would you consider simply buying an inverter and maybe beefing up your battery? Yes, running full out your charger won't keep up, but many tools are intermittant use anyway. Or beef up your alternator LOL.

I was thinking of what Howard suggested as well. For an intermittent load it would be easier to get an inverter. At one point I think JD had an inverter as an option or even a special model with AC outlets using a built in inverter. You can buy 2 bearing generator heads designed to be driven by belt from Northern Tool and probably from other suppliers. There were some generators designed for GT's that are out there but may be hard to find on the used market.

There have been many times were I wish I had one of those. I don't have any real help but I think wheel horse and sears had factory generator attachments. I will be watching this one very closely!

Casey , a few years ago I bought a generator that was V belt drive , guessing it went underhood of some service vehicle . Looks like an old Ford generator came with a box with an outlet and switch , don'tknow for sure if it works ( was supposed too ) paid $25 and you can have it for that if you want , Al

Al,
That sounds like what I need. Do you have any pictures or specifications for it?

Thanks Al. I am sure I can figure out how many amps it puts out, if it works and puts out 120v ac.

If you can get away with 120 dc , years ago we installed kits for our work trucks that would by-pass the stock voltage regulator and had a switch , outlet and indicator light that when you raised the rpm's and the light lit you would have 120v dc . I did a search but couldn't find any info the the net . My work truck here has a SST ,alt reg. set-up that does the same thing but also you can stick weld with it , which works very good , repaired broken auger shafts which had broken off in a holes . I don't think there made anymore but if you come accross one of those it would be very handy for you too . , Down side if you plug a tool not rated for ac/dc it only lasts about 10 seconds , :( Al

Casey , here's some pics of the generator set-up. No tag but there are some #s . Nothing about the amps or watts.

Al,

That looks interesting, definitely interested in getting it in my hands to better understand it and start to try it out.
