Today's junkyard find.

[Kbeitz]

An 873 is a serious machine. For 1500.00, that is like stealing. Some would pay more than that for an 873 carcass ;D

But I'm kinda disappointed that it's not a kubota engine.
It has a Deutz in it. Are they any good?

[Crusarius]

Terrible. I will come pick it up and relieve you of any agony

[Kbeitz]

I did find this today. I was told it runs good. They said it was
brought in because it was to small. 4000 watts.
It did not feel small when I loaded it in the back of my Jeep.

That Onan was probably out of a motor home .Although most of them had a 7500 watt unit .

I had two others that came out of a motor home that was 4000 watt.
I would think it would depend on the size of the camper.
What I like is that these are low RPM engines that last forever.
I wish I knew the HP of the engine. It's not marked anywhere.
I bet it might make a good mill engine.

Edit....

Google says it's a  9.5 HP. Displacement, 304 cc

[Hilltop366]

Maybe you could leave your new skid steer at the junkyard for loading!

[starmac]

I had a 40 foot fifth wheel with a 4000 onan, didn't even realize they used 7500 watt ones in rv's.
I forget just what it was about it, but I pilled apart a smaller onan generator and the engine was pretty much especially built for that purpose, not suitable to use on anything else.

I blew up the motor on my dads lincoln welder and found that it had a tapered shaft. Only the same motor would fit back. I never ran onto another one and it is still in parts out in the barn. Very disappointing.

[Kbeitz]

Don't give up on the tapered shaft engines. Cut the armature off
the generator next to the windings. Slide the sawed off chunk
back on the tapered end of the engine. But a bolt through the
hollow shaft and bolt it tight. Now you have a normal engine.
I've done this many times.

I have one of these!  Came out of a motorhome, and is 4,000 watt and runs at 1,800 RPM!

Only issue I have is I need a coil for it!  It takes what is referred to as a double coil!

Seemed to run forever on 5 gallons of gas!

The coils are on E-bay often.

[pineywoods]

The 4kw onanas were used on motor homes that had only 1 rooftop air conditioner. The coils are unique, but can be had. They fire both plugs at the same time..A clutch off of a golf cart will fit the tapered crankshaft with a little lapping.

[Al_Smith]

Same coil as a Harley Davidson ,cheaper .

[Al_Smith]

My parents had a 7500 Onan with a 3 cylinder Yanmar water cooled diesel on a motor home ..It would not carry the load until it reached operating temperature nor shut down until it cooled  below a certain temp .Very well designed .Glow plugs, it probably would have started on the North pole .
Being a 4 pole generator running at 1800 it's probably a 16 or 18 HP engine .Should be able to tell from the engine name plate by referencing the model number .
We had a little Miller welder generator with a pancake Onan .3600 RPM  for welding which was about 5 quarts of gas per hour .1800 for generation which I have no idea but it went a long time .It was an 18 HP if memory serves .,5,000 watt .

One of our A300 Bobcats has a Deutz in it. Great engine. No antifreeze. Just oil and air for cooling. Always starts. Stingy on fuel too.

[Kbeitz]

No antifreeze ? Wow. New one on me ... Thanks.

[paul case]

Yeah those Duetz engines are air cooled. They have a screen on them that needs to be kept clean, at least the tractor engines do.

PC

[Kwill]

My neighbors have a duetz  tractor. Its really good on fuel and has been a really good tractor. Always starts even when the big JD won't .

[Banjo picker]

Kbeitz there should be some kind of alarm to let you know if the belt breaks or comes off.  That or some kind of tattle tale switch to shut it off should that happen.  Without the fan turning the motor will be toast pretty quick.  Use to have a couple Liebherr 921 trackhoes.  They had the air cooled Deutz,  My ex partners little brother got one of them too hot....not good.  Banjo

[Kbeitz]

Looks like I'll have a lot of new to learn...

[Don P]

Nice engines, we swapped one out a month or so ago, figure the original one was over 40 years of hard service old;

Good idea Banjo, maybe something like a tensioner type wheel riding the belt, when it drops in a switch to a dash light closes.

[pinefeller]

oil cooled  ;) mine has 10k hrs and burns no oil and the oil is still clean at 200hrs after an oil change.

Share what kind of oil you use....

[pinefeller]

i was actually giong to call the guy that did it last and see what he used, its due again. i was told this phenomenon has to do with being oil cooled instead of antifreeze and not being turbo charged. im pretty shure he said texas refinery so it should be rotella t (i believe shell is owned by T R. im used to losing a half gallon or so between changes in pretty much all large equipment ive maintained and black oil by 200hrs. this engine has been unbelieveable, no leaks, no burning, good power and pretty quiet.

[Kbeitz]

That would be great. Rotella is what I use in everything I have except
my cycle.
