Funny, I have a 803 and think how handy an 802 would be. (As a second unit.)

And it ran ~7 hours with varying loads and the oil pressure is still ~60psi and no extra oil appeared. So it's back on its trailer.

240 single phase. I have 2x3800W and 1x4500W. But I have a 803, not a 802. My goal was 12Kw.

I use water heater elements. Space heaters would work also.

Trying to buy and just run it. While having a learning experience in engine repair. There's some gamble in the purchase, but also there's a lot of upside when things work out.

Yeah, another lesson I'm learning.

Thought about it. Put all but the pump I messed up with back in. Verified the rack moved with just the one missing. Figured it was bent or it wasn't. But your logic made sense so stuck a J-hook into the pump hole and attached it to the rack. Pulled. The last pump dropped right in. Went to see...

I'll take it. https://1drv.ms/v/s!AnhaA1TwRcf6k7RQrcZPYonkeLEodQ Load test tomorrow. Need to pull the Prime Rib out of the Sous Vide... Merry Christmas.

That's not a bad idea. Should be able to fabricate something to pull with pretty easily. (And an excuse to use some of the new welder stuff I got.)

And I'm now about 95% sure I managed to bend the rack. If I manage to get all 4 pumps aligned with the rack, one pops out the second I move the shut off solenoid to run. I did once try to assemble the pumps with one at the high spot on the camshaft, so it pushed on the rack. Missed that page in...

While I've been worried about having bent the rack (and still am) I'm hopingjamawieb's right on this one and I'm still a bit lucky. Looking at this photo, you can see how close the top of the pump is to the block. And when I drop the pumps in and get them aligned in their slots in the rail...

It's not a matter of getting the pin in the hole, or the slat in the rack. Once the pin is in the rack, something is binding the rack up and it's not moving anymore. I got frustrated and went exploring with an inspection camera. Here's a view of the back of the rack (governor end) where the...

Looks like that's injector pump is for the marine version of the engine... While I work on getting that all straight, I figured I'd put everything back together and make sure I didn't screw anything else up. Well, sure enough... There some trick to getting the pump to slide into the fuel...

Nope. And that worries me about the rest of the specs. I reached out to the vendor, we'll see what the response is.

Onan 186-6151 The vendor lists this as a MEP-803a fuel metering pump. Picture is of the right one.

This, that may slow things down a bit. New pump... Grumble.

Ok, now I'm confused... From the TM: If original shim thickness is not known or if fuel pump is being replaced, fuel pump must be timed. Ok, so I'd need to time the pump... But later in the TM: 3-14. FUEL INJECTION PUMP TIMING. Each fuel injection pump is timed individually during assembly at...

So, the naive question... This as simple as tightening everything up? I'm likely the yahoo who loosened it back in March when I first got it and was trying to bleed the fuel lines. Cause I have this memory of thinking "That was the wrong thing to wrench on." Or did I manage to mess up the pump?

And that pump... Pulled it, and had the pump all but come apart in my hand. The top of the pump was barely hand tight.

I *thought* it was running good. It ran with 12.5kw load 2 months ago for ~30 minutes without a stutter. Little tinge of gray in the smoke with that load, but that's it. I have nothing to compare it to besides diesel trucks for sound, but it didn't sound like a train wreck. Maybe I got a...
