Today went sideways at work with a LN2 leak. Technically it was a gas vent malfunction. We had what looked like a 5' tall hornets nest made of ice hanging from one of the vents. Getting it down without putting the LN2 line in danger or popping a hole in the rubber roof was fun. We "cut" it into...

Right now the generator is ALL stator! :) I have to pull the engine to figure out why as stated above. That will give me the oppportunity to get the engine on a stand and into a better working space anyway.

Yea, that is the leading theory now. The additional mystery is why the generator head isn't turning with the engine. It's an interesting puzzle.

Actual update.. Had some time in the sun this afternoon after work to do some tinkering. Went out and pulled the radiator so I could turn the engine a bit easier. Well, the crank is not broken. When I was able to spin the engine a little faster I could tell each cylinder did have a little...

This is an update of sorts. I have a few units to get going and I need to get the APU I bought a couple of years ago up and running. I'm also going to spin this project unit over with the starter again to double check some of my troubleshooting. This guy is going to make all that happen. Look...

There has been a slight delay of game due to the weather being too prefect for spring yard work ahead of todays rain. Good news is I have most things planted and can get back to the generator.

Sounds like you are on the right track. I would recommend taking the batteries out to charge them. If something happens and they vent you don't want that to happen inside the unit.

I need to replace my batteries but I haven't yet since its not camping season here. I'll share what I find out when I do. I may go with some lithium batteries though since I have a bunch. Not as simple as the SLA batts since the lithium need a controller to keep them from catching fire. The...

I can't wait for everyone to see what these things do. I'm going to put one in every machine I have. I expect there to be good demand for them once Kurt is ready to release them upon you all! :D

I appreciate the credit but in this case it wasn't me. This fine work belongs to Matt aka Sewerzuk. https://www.youtube.com/watch?v=YmF4Awr3uc4

I was planning to take the side cover off and take a look before removing the engine. We have a stretch of good weather for the next few days. Hopefully I can get home from work in time to take advantage of the evening sunshine. I'll post what I find.

The side panel over the fuel filters was removed by the person I bought it from. It has new fuel filters. I've gotten a bit more info and he indicated that he did run it after getting it home. He did a really good job cleaning the engine compartment. I took the top off the engine compartment...

Awesome. Thanks. I'll go check that out.

I'm still going to tear this one down and see if I can figure out what happened. I have a good idea what happened but want to see if my thoughts fit what I find inside.

Thanks. I checked but didn't see them on the website so I sent them a note. They are showing the DM2 but not the DM4. Lets hope they have some stashed in the back that aren't on the website. I expect buying a running engine for $1k (plus shipping) is going to be the low cost option to get this...

I'm going to see if I can find a reasonable replacement engine. I suspect this one has a broken crank.

That is one scenario I've been rolling around in my head. That means a much more serious repair.

The plot thickens. If you turn the fan by hand (the crank pulley and pulley bolt are turning) the generator head does not turn. Looks like I'll be totally tearing this thing down.

Picked up a MEP803 that didn't run. Starting to go through it. Looks like it has a blown head gasket. Hoping its not freeze damage. No signs of a cracked block on the outside. There are a few parts missing but nothing that would keep it from working. I'll see if we can get the old girl back in...

I'm west of Raleigh. Be happy to help if I can. You can pm me to work something out.
