20 KW Generator Questions

Should be. Naturally the Kubota will be right because it is 6 spline right out of the tractor, and the bulldozer just has a direct drive to the engine. In the latter case, I will just have to throttle it down to get the rpm's right, but it also has the horsepower to carry the load.

 

6 spline...so 540?...I take it the genny input shaft is going into a gearbox? Sounds odd to me that it would have a keyed 1.25" input shaft if it is setup for 540, or even 1000 RPM PTO drive...genny itself needs to spin at 1800 (IIRC) for correct HZ

 

That is what I thought at first too, but it is just a Winco PTO Generator thing. I did a lot of research on this very thing before realizing it is just this odd thing Winco did on the 20-25 kw units. You can actually buy a PTO shaft direct from them with 6 spline on one end, and on the other a 1.125 bore....at $250 before shipping...but I found a workaround, as suggested on this forum or another I frequent.

On PTO generators though, to get the frequency and voltage right, you throttle the tractor up until the voltage meter goes into the green which is always situated so you can see it from the tractor seat. It works, but is not exactly fuel efficient!

Did you ever get the brush cover off ?

 

I offered to give you the WinCo shaft I took off mine. 1 1/8" keyed and 1 3/8" 6 spline.

 

The generator is 2 pole 3600 rpm if it's the same one as mine, only difference is that mine was ordered 3 phase. The straight shaft I was told was a cost cutting measure because being trailer mounted the shaft never came off as it clipped to the trailer itself.

 

Hey Screwloose , I did not mean to slight you! I thought it was a person on here, but could not seem to find the right post where you said it. I will always give a shout out to those that help, so sorry you did not get your due reward.

I got the Generator to power the house today. That was a good thing until the wife turned on the electric range to see how it would load the generator. We had 2 inches of rain and 3 feet of snow literally melt over night so the ground was saturated. I snagged the cable going from my barn to my house, and apparently pushing that much juice did not bode well. One leg of the 240 line grounded out and blew a resistor off the 120 outlet on the generator...that caused my heart to jump there for a minute. But ultimately it does work.

 

Well it definitely found the weak points in my electrical circuits that is for sure. We had it wound up pretty good and was putting increasing loads on it when Katie turned on her new kitchen range. That was when it touched off. One of the resistors on the 120 outlets let go and blew aluminum all through the electrical box, tossing some aluminum on the fuse knife points inside. My father shut the tractor down, but it was quite the sound and light show still.

Last winter when I was cleaning snow off my driveway, the main power cable going to my barn (220 entrance cable) got snagged by my bulldozer so last summer I spliced it. It is in a bad spot because the water coming off the backside of my house runs there and I means runs...like a stream. It must have got a hole in the shrink wrap splices and went to ground because we are only showing 20 volts on the black, and 220 on the red side.

I would have thought some breakers would have tripped, but the breaker was made when Edison made the light bulb and that is not far from the truth. It is so old that there is no way to even get them on the internet, I tried. But maybe circuit breakers are made to only trip in one direction? I am back feeding through my entire house. I probably should add a few extra grounding rods, that might have helped in this situation.

Now I have to find a 120 outlet resistor, something seldom not done today.

 

Be careful......

 

Well here is a picture of the old girl, but it is not painted. In the frozen mud it looks kind of nondescript, and uneventful considering the 3 pages this thing has taken up. Not a lot to them anyway I guess which is a good thing: less complicated=less things to go wrong.

 

I took a picture of mine and I'm wondering if what you are calling resistors are actually just suppression capacitors. Also did I read correctly that you have 220 volts on one wire to ground/neutral ? Is this on a outlet/receptacle single terminal to ground ? Lot's of taps on a WinCo, it's even possible you could have a third phase.. Also the 110 outlet on the cabinet probably needs to have the jumper snapped off as each half of the receptacle is on a different phase.

 

Yeah it is probably a suppression capacitor, I did not know the name. It is that silver can looking thing above and below the 120 volt receptacle. My generator is only single phase though.
