It was the power plant out of an electric company line truck, and it even has an attached (belt driven) hydraulic pump. I presume that drove the boom/crane.

It's still in the back of the truck and knows nothing about it. So I can't go out and play around with it and examine it just yet.

But it appears to be an Onan 4.0 DKD. Which would be powered by a Kubota D650. 15HP at 3200 RPM. (which is the max RPM) And the pictures I'm finding online seem to confirm that.

So now I just need to decide what to do with it.

1. Install a fuel tank, get it generating, and sell it for much more than I paid?
I already have a whole house NG genset, so I don't need this for power purposes.
2. Remove the generator head and install it as the powerplant for the towable backhoe that I'm going to resume building any day now.
(I had planned to power the backhoe by long hoses inserted inline with the quick disconnects that are driving my loader)
3. Keep it onhand for the fateful day when the 20HP Linamar in my Loader gives up the ghost. Clearly not a simple repower. But conceivable. And I'd love to have a diesel powered machine.
But 15HP isn't terribly much. With the power steering, I figure my hydro system can make use of about 15hp. And I currently have 5 extra HP to drive the PTO. On the other hand, my old 442 did just fine, and it was only 12hp. So I know that 15 ought to be at least minimally enough.

And I'm not sure anyone has yet successfully done a diesel swap and preserved the PTO drive for the deck and such. And that's not optional for my purposes. It has to mow with no compromises.

And the 3200 max rpm would slow down my travel speed and force me to play pulley games to keep my blade speed up to normal.

So as cool as a diesel mower sounds, it would take a lot to get it to work right.

So I guess I'm leaning toward having my towable backhoe be self-powered.

What would you do if you were me?

I am not overly fond of it either . For me and especially the it is burnt gear oil . That Bob is a whole other level of smell that you can't get rid of . Being a wrench turner for 30 plus years I have rebuilt many of rear axles and there were times that the made me sleep on the couch .
nitrate gloves and a Tyvek monkey suit will help , but like Jeff said they are hot to ware . But wurst of all is that there is only one place for your own personal body aromas to leave the suit and that is through the neck opening .

I didn't enjoy it. My British friends would call it "fiddly." Very fiddly.

I couldn't find precisely the correct manual or video for it, but I watched a couple that were consistent enough that I was able to apply the knowledge to this one.

It turns out that each of the 3 "pumping units" are actually small (5/32" or so) precision ground pins reciprocating inside precision honed sleeves. The pin is the piston, and the sleeve is the cylinder.

The pin has a vertical slot (think keyway) and the sleeve has a hole in its "cylinder wall" near its midpoint. So if the pin is rotated to a certain position in the sleeve, then the "keyway" slot can draw fuel through the cylinder wall hole, and with each stroke a bit of that fuel will be "pushed" upward to the injector. But if it's rotated to a different position, then the keyway is away from the hole in the cylinder wall, and no fuel is pumped.

So the volume of fuel is controlled by rotating that pin.

The pin is indexed inside a gear-toothed collar.

And moving the control rack rotates that collar.

So sliding the rack rotates the pins, which causes them to pumpeither a little or a lot of fuel.



But those 1 inch long pins sitting in those 1 inch long sleeves, with maybe a thousandth of clearance were very solidly glued in place. They couldn't move up or down, they couldn't rotate. So the geared collars couldn't rotate, so the rack couldn't slide.

I had to drive the pins down out of the sleeves with a punch. (Delicately). Cleaned everything up, washed it in gasoline, lubed it all up with wd-40, and reassembled everything. Now the pins reciprocate and/or rotate freely. Rack slides effortlessly.

It'll probably be Thursday before I can put it all back together and confirm it pumps when the engine turns over.

Assuming it does, I expect to have a runner!
