Fuel use in Kubota 10,000 watt generator

No good serach results so let me ask

What is a fair estimate of the amount of fuel my Kubota will burn per hour?

If its a diesel and anything like my garden tractor with Kubota diesel --  You should be able to run lots of hours before worrying.  With my old gas tractor, I was always filling it up,  and with the diesel I can mow 5 or 6 times before filling up.  5  or 6 times  is like over 5 or 6+  acres.  Same with plowing the snow during the winter months.  It runs and runs and runs, and only sips the fuel.  Wish I had a diesel generator!!!

My Isuzu 7 KW Genset consumes approx .5 gals/hr when running both A/C's while on the road.  Compare that to the consumption of 7.5 gals/hr for the Cummins 325 mechanical engine at 60 mph speed.  That is, I normally get 8 mpg w/o genset running and 7.5 mpg with genset running...roughly.

Hi George,
  Our 10K gen, 1997 U 320, uses about .5 gallons per hour. This is with both roof airs running.

.5 gph is about right. I have the same 4 cylinder Kubota

Happy days, You will have a real hard time burning more than 10 gal per 24 hr day.  That would be bout .41 gph.
This is not a guess, not an opinion, have run these RV genset diesels for over 20 years and when using a separate fuel tank, it is easy/simple to get a real good number over 8,000 hrs running time.
Enjoy and let it run, you will not wear it out, unless you ignore it.

Thanks, guys.  That is most helpful and I have written it down.  On paper.  In a notebood.

One small point I should make. If you start to add up the hours on the generator, we have found that before 5 k hours, need to replace the sealed ball bearing that holds the end of the generator, not engine end. Not a big deal to replace.
Very costly when that bearing goes bad and drops the rotor into the stator.

Dave, I have heard this before but I am not sure of what the process would be to replace this bearing.  Can it be done with the genny in the coach ? Mine is mounted in a side compartment but I have never looked at access to the front end of it.
Thanks

Dave,

What do you mean by not engine end?  Would this be the end with the fan?

Gary, the generator will need to slide out enough to remove the end with the bearing , not a big deal.

George, picture the left end of your generator, that is the generator end where the said bearing is located, not on the engine.

OK, As you are looking at the generator AFTER you have the door open.
Yes it would be the passenger side.
Yes, my generator will slide out after you remove the bolts in the exhaust and the slide frame work, then you can slide it out a ways, to total remove it will require disconnecting the fuel lines and electric wires both AC and DC and a method
of supporting it.
I have not replaced the bearing on my unit yet as it only has about 1400 hours total, but about 4500 hrs IF I am still living and still have the coach and still using it, I will then either replace the bearing OR have a generator shop replace it.  Will not have a happy do everything mechanic with a tool box and a hand full of rags touch it.

Proper mechanic will know how to get to it and what I am talking about.

Re: 10KW Generator Fuel Consumption

Per Power Tech 10 KW Owners Manual, they say the hourly fuel burn is ;
LOAD % = GPH fuel burn as follows
 25% = .26 GPH :))
 50% = .47 GPH ::)
 75% = .74 GPH :-X
100%=    1 GPH :o

Maybe someone is wondering.
For my operation, I would guess I am running about 40% load, having one 194 gal fuel tank, that is supplying all three needs, it is impossible to give an exact number for the fuel burn, so you need to have a realistic guess as to % load.

Using the numbers I had when I used the MCI conversion and had a separate tank for the genset, running it 24/7 it averaged 10 gal per day using a 12 kw that was lightly loaded.
FWIW

At what level of fuel does your PowerTech generator stop running?

Reply #16
2000 U320  generator shut off at 1/2 full.  We were surprised.  :o In fact we were going to stop today to take on fuel, but could not find a station we could enter.

Where does yours cut off?

My genset cuts-off at the 1/4 mark.  Make sure your fuel gauge calibration is right.  At 1/2 tank, when you fill next, see how far off it is from being really at 1/2.
 
Modified:  If you have to drive...say 100 miles...to the next fueling station...approximate the consumption to adjust your fuel calculation back to the 1/2 tank level.

Peter,

That is an excellent suggestion.  We will stop within the first 10 miles to fill the tank.  I will report our findings.

Our fuel gauge is pretty accurate I think.  We can operate the generator down to at least 1/8 tank.  We have the 191 gallon tank in our coach.

I consider it prudent to keep the tank above 1/2 full. I calibrated the tank so that when we use 70-75 gallons of the 140-150 gallon capacity, that gauge is at about 1/2. We fill frequently to: 1) stay safe in case there is some emergency that precludes getting fuel; 2) add fuel blended for the climate in which we are traveling; 3) cut down on condensation; 4) avoid the issues associated with introducing air or other foreign material into the fuel system.

I am going to add fuel some time. I prefer to add close to the time we are going to park for the night, or for the month. I know the generator will run with at least 60 gallons in the tank. I don't plan to test for lower levels. I am very satisfied to let you good folk test that limit for me.

To the great list below about driving in the top half of your tank,  I would add to get out and walk around, and maybe even defeat a blood clot...

I usually keep my 180 gallon between half full and completely full, but there have been exceptions.  I have run to just above quarter full, and the generator did run. I really don't want to test this and fuel-starve the genset on purpose.

Before my last FT appointment I ran the fuel tank as low as I could because I suspected a tank leak.  The needle on the gauge was at empty.  The low fuel light came on.  The generator still ran.  When I refueled, it took 148 gals, which cost $452.47!

My 92 GV with an Oskosh frame and a 460 gas has the generator pickup about 2" above the fuel pick up for the engine.  I have had the tank out 4 times trying to figure out a fuel pump problem.  If FT designed the complete system, they would have a spec sheet for the tank mfg and would know how high the pickup is suppose to be above the engine pickup.  They should know from that how may gallons were left when the generator starves out.
