Looking at the performance curve it looks like 2400 rpm should be fine.

I will need to get the digital tach out and do some tests to see how smooth it will run at that rpm.

That starter ring gear equipped flywheel that doesn't work to make your fingers into hamburger is a nice feature.  I had a run in with my 1115 that was serious but could have been a lot worse.  Nice engine!

Thanks rcavictim,

The only place where you can get your fingers ground up is where the Stub Shaft mounts. Any other place it is almost impossible to get a finger near the flywheel, fan, pulley's and belt.

I understand what you wrote about the 1115 flywheel. Having an S195 without guards is very dangerous. I was always nervous being around it when it was running. It would not take much to get seriously hurt on one of those engines.

I sure don't let the grandkids even near mine when its running, little fingers can be a lot faster than my old worn out reaction time!
Matter of fact, I don't even run it while they're here.
Seems the older I get, the more danger I perceive.

Ron,

You are correct,

My daughter does not get near any of my engines when they are running. She knows to stay away from them and understands they can hurt her.

Just because the EA330 engine has guards, that does not mean you can have your hands all over it when it is running. I still follow safety proceedures.

I run 2200 rpm  on my EB300. It is both peak torque and best fuel consumption RPM.  Been doin that  for 3 years or so. Call it about a pint an hour or so.  Pretty thrifty for the charge I get out of it. I use a Tiny Tach.

I run about twice each week, November to mid March. About 3 hours at a stretch till I reach float on my battery bank (420 AH at 24 volts). March till November I get a full solar charge each day.

I learned the hard way, I will carry to my grave a  scar from dropping a 1/2 open end wrench into the  running open belt of an air compressor
I cobbled up years ago. But for the Grace of God, I would be dead.

vdubnut62,

Some of us get a second chance in life and the best thing we can do is learn from it. Also help people so they don't make the same mistake we did.

I test ran the engine at 1800, 2000, 2200, 2400, 2600 2800 and 3000 rpm's and observed some intresting results at all those rpm's.

Forget 1800 and 2000 rpm. Shakes and and pretty good fuel knock.
2200, Engine just starts smoothing out. still considerable fuel knock.
2400, engine smoothes out more but still a fair amount of fuel knock.
2600, engine slighty smoother yet and fuel knock is much less.
2800, engine very smooth and fuel knock is pretty much gone.
3000, engine very smooth and fuel knock is pretty much gone.

My test results shows that this engines optimal rpm range is 2800 rpm.
I wanted to see what the engineer I know that builds generators with these engines thinks what the best rpm range would be for this engine. He said from 2800 to 3000 rpm. He said they set them up at 2800 rpm.

So my observations were pretty much the same, and 2800 rpm will be the goal for this engine to run at.

I was going through differant Kubota engines. The EB300 is spec'd differant than the EA300 and EA330.
Timing is advanced more on the EA series engines. And they are set up to run higher rpm's.

This is probably why they have a pretty good fuel knock at 2200 and 2400 rpm's.

Hi henery

It's probably, trying to meet the Tier requirements...the leaner burn of the 330 had to come some way.

I believe your right. I am thinking of looking into camshaft profiles of the EB300, EA300 and EA330 engines. If they are the same than there is a posibility of setting the EA330 to run at lower speeds if needed. The injection pump, nozzle pressures and timing can be changed easily. But for now I will use it as it is.

Had me going there, Henry. I couldn't figure the large difference between what you are seeing with the  ea330 vs what I have seen with my eb300d over the last few years. It may very well be the timing. I was a little concerned that I was mistreating my beast. thanks for the data points.

I ran mine under load last night and it is nice and quiet at 2200 and very slightly quieter at 2400. Actual output was initially 65 amps at 24 volts. Best I have seen is 80 amps and that was into a 420 ah battery bank at 70% SOC. I rarely ever go below 70%.

I just recieved the EA330 Workshop and parts manual and the only differance that I can see on the EA300 and EA330 so is:

1. Displacement

2. Injector nozzle (The rest of the injector parts are the same part numbers)

3. Injector Pump timing.

The Camshaft is the same on both engines. Part # 14971-1615-0

If anyone has an EB300 or EL300 parts manual can you check and see if the part number listed above is the same.
