Title: My new generator
Post by Dave on 09/17/24 at 15:53:53

I just came home with my "emergency" generator in preparation for the upcoming "apocalypse" (or green energy power grid meltdown).

It is a 5 kilowatt, diesel - weatherproof, EMP proof....and battle ready!

I sold my gas generator and bought this as I have a large tank of diesel fuel for my tractor and lawn mower - it just made more sense to have a diesel generator.

It can also be used for short power outages caused by storms if the need arises.  The grey box on the side is a 50 amp/220v receptacle so I can plug it into garage  - I installed a generator/main fuse lock out device so the generator cannot back feed to the power grid.

These generators are 20 years old and need a bit of love to become reliable....this one has a fuel leak in a return hose from the injectors that will take an hour or two to fix.  The rubber fittings at the fuel tank are also known to deteriorate and leak fuel.  It only has 25 hours of use on the 2 cylinder diesel engine - so there should be several thousand hours of life left!  The dang thing weighs 800 pounds!

I'd go ahead and get some copper crush washers for the injectors. They don't cost much at all and if you're using it there is a decent chance you won't be able to buy them. They are One Time use goodies.
How did you get your hands on That!??
Diesel has more BTUs per gallon than gas, so, under the same load, it had Otta run longer . EMP proof is great. Is the refrigerator, heater and AC gonna be operable if someone pops one? The tractor should be okay.
I Wonder about bitcoin.. Hmmm..
Congratulations, Dave, that is a great thing.
I probably would have just pickled the gas unit and put it under a metal window screen cover and covered it up.
YaKnow, if a coupla injectors can head for a reasonable price, mehh, spare parts for The power supply is maybe a good idea.

You can buy these surplus from several sources - GovPlanet is one.  However there is a bit of a gamble as to what you are getting. Sometimes you can get stuff that is in incredible shape - other times there may be something that missing or non-working and you may need to do some repairs.  I bought this from a fellow on the Facebook Marketplace who bought it from GovPlanet and there were two generators mounted on the trailer and he only wanted one.  He got it running and proved it was functional.  The 5KW model is called the MEP802 A.  They also have a 3kw version called the MEP801 A, and the 10kw model is the MEP803 A.  They also have really big ones in 30kw.
https://www.govplanet.com/

All of the electronics are sealed by heavy steel covers and/or doors.  There is no direct path for anything to get inside (water, EMP, etc.), and even the gauges have a thick metal cover to protect them.  That is one reason this thing is so darn heavy.

There is a website forum like our called SteelSoldiers that is all about surplus military equipment care and feeding.  I will be a NOOB and become a member!  Maybe I will learn from them what kind of spares to stock up on.

The trailer belongs to a neighbor friend.  It was sitting in his driveway with broken wiring, weathered and cracked tires, a foot of leaves piled up on the bed.   I was in the need to use a trailer like that about 6 months ago - so I made a deal with him that I would clean it up and get it working if I could borrow it.....he said he would pay for the parts.  I washed it, put on new tires, put on new wiring and lights, replaced one wheel bearing set and cleaned/greased the other side.  It worked out well for both of us and he is using his trailer again - and so am I!  I spent a couple of days working on it and now I can borrow it whenever I want to!

You might consider a tractor PTO driven generator if you want to run your whole house - or a small generator that would burn less fuel.  Running the fridge, a couple of freezers and some lights and a TV takes only about 3,000 watts, a 5,000 watt can run our wood burner and get us heat.....if you want to run your house as normal you need 10,000 watts or more (electric water heater and an electric furnace require a lot of power).

If you have a friend that works at an airport "Jet A" fuel is a good lamp oil and it burns cleaner than kerosene.

I wonder if that what it will take to "Make America Great Again"   :)

If we had to go back to living like we did in 1925 , some of us would be OK after a few years of it , but I think there would be a lot of wild stuff in the middle years !   :-?

Do small airports sell to folks with yellow 5 gallon cans ?    I do have an old neighbor who hangs out at the local airport.

I've got a 6000 watt modified sine wave inverter , and a 1000 pure wave inverter .
Do ya'll think a regular truck battery would work with a solar 200-300 watt panel ?
I do have the "jump-start" box to get the truck started again if it get's too low.
My truck does a lot of sitting on the car port going no where most of the time  ...  unless it's Really Cold or Raining .
............

Hay Dave , my 25HP tractor can work hard all day long on 5 gallons of diesel so a PTO generator that can operate on 540RPM (or less) would be a good thing . :)

If you're going to risk driving a battery that hard, you might want a Deep Cycle.
Ohh, the InUendo..
Those little jump boxes are just a very slight step away from black magic.
Such a small, light package,, that boggles my mind well enough, but the scrawny wires they feed the dead battery through just blow me away. I have some jumper cables that are probably twelve feet long and I have no idea what they weigh, but they are substantial. I got them so if the backhoe was cutting through stuff and wound up with a dead battery I could bring the truck up behind it and still get to the battery. I bought them before that scenario was a reality... But it happened eventually.
I'm gonna get one of those jump boxes. I see them used on YouTube videos. Like Matt's Off-road and others.
The battery that starts the car weighs quite a bit. A jump box weighs what?

Title: Re: My new generator
Post by Dave on 10/03/24 at 02:28:41

I have been working on the generator - just like an old bike that hasn't been used and maintained regularly this thing needs a bit of work.

The generator was built in 2005 and it only had 15 hours on it when the previous owner bought it from GovPlanet.  They got it running and put another 8 hours on it - but other than putting batteries in it I don't believe they did much.

The fuel tank fill neck was rusty, and the diesel fuel in it was a strange orange color with a lot of orange sediment in the tank.  The fuel return line from the injectors was leaking and weeping oil down the engine, an the bottom of the cabinet had a diesel fuel coating from the weeping rubber plug that was supposed to seal the fuel line exit in the plastic tank (expanding rubber well plug that was aged and split).

This is the view into the fuel tank.

Title: Re: My new generator
Post by Dave on 10/03/24 at 02:37:56

Working on this generator is not all that complicated - but there are lots of small screws/nuts that hold the cabinet together and it takes a lot of time to get things apart.  The fuel tank required the radiator portion of the cabinet to be lifted a couple of inches to make enough clearance - there was likely 50 screws/bolts that needed to be removed.

The rubber well plugs in the fuel tank supply and return have been replaced with brass fittings with O-rings, and these will not deteriorate like the rubber well plugs did.

The process of cleaning the fuel tank, replacing the fuel return lines, installing new fuel tank fittings, installing new fuel and oil filters, installing a new fuel level sender to replace the original rusty one and getting this generator back into shape for reliable running will cost about $200 and take me about 20 hours of work.  (I am telling you this so you can understand that old equipment can be time consuming to get back into service).

This is what came out of the fuel tank.  Thankfully the tank is plastic and could be cleaned up easily.  I don't believe any of this crap got into the fuel injectors as it was laying on the bottom of the tank, and there is an inlet screen to the low pressure electric fuel pump, and 2 fuel filters after the pump prior to the fuel reaching the injector pumps.

Thankfully that crap laid on the bottom of the plastic tank and didn't get picked up in the fuel system....the filters were pretty clean looking (but I changed them anyhow).

I'm beginning to think I should look-up PTO generator on ebay !   :)
..............

I did get a "900 amp AGM battery" for my truck and put it in today to run my 6000 watt inverter.   The original battery (AC Delco/GM) was still in it from 2017 but it was going to low to start the truck if it sat for more than a week.
6000watt / 120volts = 50 amp ... but that means 25 amps running power.
I think a 15 amp load might be "OK" ?  
So It should run the fridge for a few hours a day.   I hope ...

The fuel system and engine are not any more intimidating than working on a diesel tractor.  The engine is a 2 cylinder Lister-Petter design that was built by Onan.

The electrical system is far more intimidating - it is incredibly complex.  The engine shuts down for low fuel, low oil pressure, overheating or over voltage.  The electrical system can also make single phase or 3 phase in 120 or 240 with the turn of a switch.  There are knobs to fine tune the frequency as well as the voltage.  There is an electric pump that pulls the fuel from the tank and carries it to the injectors, and another pump that can be run to another fuel tank - this pump comes on when the main fuel tank drops to 1/3 and then shuts off when the fuel tank reaches 3/4 full.

Tractor PTO generators work great - my brother in law had one on his dairy farm and they needed it anytime the power was out at milking time....and to keep the bulk tank cool.

I wanted something smaller and more fuel efficient than my tractor - this generator uses 1/2 gallon an hour at the full 5,000 watt capacity.  I also wanted a diesel generator so that I could use the fuel oil I keep in my 270 gallon tank for my tractor and mower.

I am not necessarily a "prepper" but the recent storm event in western North Carolina is a perfect example of why I wanted to be prepared for an extended power outage.  It has been more than a week since the storm, and people are without water, electricity, cell or internet service.  Many people are still lost and/or waiting to get help, and I have read several postings of volunteer help and supplies being turned away by FEMA and other government officials.  (One story even said that FEMA would not allow volunteers to give bottled water - as the water was not from the "approved" vendor for water!

That is why I chose not to go with a PTO generator - a tractor is expensive and I did not want to have my tractor sitting outside in stormy weather at high rpm to run my fridge and freezers.  (It also would not be desirable to have your pickup truck running for extended periods to provide house power).

For the $1,300 that PTO generator cost you can buy a really nice dual fuel generator and use the propane you have in your big outdoor tank for fuel.  With a generator run on propane you never need to worry about your fuel going bad (running the fuel out of your carb and tank before storage also solves that issue and I had my gas generator for more than 20 years with no fuel issues - add fuel when you need it and it always started right up when I needed it).

A fridge takes between 300-800 watts to power, and most likely you only need to run it about 1/3rd of the time to keep things cold.  You also need to look at your other appliances to determine how many watts you need - with a propane furnace you will need to see how many watts the blower requires to run.  Gas water heaters don't take much power - but my electric water heater requires 3,800 watts....so we turn that off and don't heat water when we are going through a power outage.

It is likely that a 5,000 - 8,000 watt generator will run your house if you are conservative with the use.

I just read of a fellow who is off grid and  has been using one of these generators nearly full time  while he is getting his property established (he will eventually include solar and wind).  He just passed 12,000 hours on the generator with no major repairs!  Currently the water pump is dripping while the generator is not running - but it stops leaking when the unit is running.  New water pumps are only $40 so that is an easy repair.

My wife and I do not consider ourselves to be "preppers" and we have not gone off grid - however we have tried to get ready for some short term survival.  If Putin, China or a solar flair or storm wipe out our power - we are preparing to be able to keep our fridge and freezer running for a while so we don't lose our food supply.  Although we (and everyone else) will have a tough time - we do want to be able to eat and stay warm for several weeks or a month if needed.  Who knows what happens if the disaster lasts longer.  Currently I am in a hotel at the TN/VA border with a dozen power lines trucks and crews from Mississippi, Indiana and Texas who are working to repair power lines damaged by hurricane Helene.  The Texas crew has been on the road for 3.5 weeks as they were repairing tornado damage  before they came up here.  They said there are places in NC that will not be getting power back anytime soon - as the damage is so severe they can't get down the roads to do any work and there is no reason to get power to buildings and towns that are completely destroyed.    

Title: Re: My new generator
Post by Dave on 10/17/24 at 16:07:32

This has sure been a project!

Even though it has low hours and is in good shape - it needed some love.  The fuel tank had to come out to replace some leaky rubber grommets around the fuel fittings (well plugs).  Also the bottom of the plastic fuel tank was covered with sludge and had to be cleaned.  When I took the fuel level sender out it was rusty - so I bought a new one and replaced the old one.  In addition to the fuel level sensor there is a device with an upper and lower float - the upper one is a shut off for the fuel pump that takes fuel from a remote tank and pumps it into the main tank - the lower float senses that the tank is low and shuts off the engine (more on that later).  I removed the tank, removed all the fittings and sensors, cleaned it and installed the tank with the new and cleaned parts.

Also there is a fuel bypass line that was deteriorated.  Evidently this system allows the electric fuel pump to bleed all the air out of the system so it is not necessary to do the normal routine of bleeding the high pressure injector lines if the engine is run out of fuel.....it also allows you to change fuel filters and the bypass bleeds the air out.  These old lines were leaking and running fuel out on the engine.  I replaced all the lines with the fuel line like German cars and motorcycles use - the black line with the reinforcing cloth on the outside.

I cleaned up the oily mess that the diesel fuel had made when it leaked out, I cleaned up the sticks and twigs from the radiator area where the radiator vent at the top of the housing had allowed a mess to enter when it was stored outside.  I also painted the exhaust manifold with Cerakote to eliminate the rusty looking cast iron (it was never painted from the factory).

I put in new fuel and discovered the fuel gauge does not work - I have one of those on order.  I am also going to paint the grey cabinet for the 50 amp service box and make it camouflage colored so it matches the generator cabinet.

This is a bit more work than I expected - however it was built in 2005 and has sat around for nearly 20 years and I should have expected it would need work.  The batteries that are in this generator are dated 2019 - so I believe the previous owner bought it 5 years ago and it has sat with fuel in it for that length of time - no wonder the diesel fuel was a cloudy orange color and smelled stale.

I have learned that diesel generators can suffer from something referred to was "wet stacking" if they are not run at 50% or more of their rated capacity.  Evidently if the engine is just run at idle or low loads and is not worked - the combustion temperature does not get high enough to completely burn the fuel.  The result is the exhaust stack gets an oily residue and the combustion chamber and exhaust manifold can be gummed up.  The generator needs to be worked and gotten up to temperature to prevent this from occurring.

When everything was back together and I connected the battery and turned things on - the fuel pump would run for 3 seconds and stop....then the low fuel warning light would come on.  The fuel gauge read empty - however there was plenty of fuel in the tank.  I checked the new sender and it was working properly - if I turned on the "Battle Short" switch the fuel pump would run.  A check of the wires at the gauge showed it was properly grounded, was getting a proper signal from the sender in the fuel tank, and the gauge had power - therefore the gauge was bad......however this should not trigger a low fuel warning as the signals to the bad gauge were proper and the gauge does not send a signal to shut the engine down.

I found a thread were a guy had the same problem - when he turned on the "run" switch the pump would run 3 seconds and then stop and the low fuel warning would come on.  The thread stated it was the float switch with 2 senders that causes this.....the lower float tells the system it is out of fuel.  The sender in my tank was in good condition and the floats moved easily - and this problem did not exist prior to me cleaning the tank.

I thought about removing the float sender and looking at it - but first I decided to wiggle the generator around and slosh the fuel a bit to see if the float would move....and it worked!  The bottom float must have been hung up at the bottom and didn't move when I added fuel to the tank.  The fuel pump now runs continuously when the stitch it turned on and the warning light does not come on.  (The fuel gauge is still reading "empty" and a new replacement gauge is in the mail).

I'm still confused as to the Why all the complexity of the fuel system. It's got some really trick pump/self bleeding so if it runs outta fuel, ya don't have to crack injector lines and crank it until ya get the diesel to squirt out, but it also has a low fuel sensor to keep it from running out. I'm not against either one, I'm just wondering why they built it that way. I wonder how long it takes for the self purge/prime the pump and injectors if the low fuel sensor fails and ya Do run it out..
I've never heard of a system that would do that.

What is the big solenoid with the bellows and the arm going to the left? Looks a lot like a kill.

If you're running it but the load is insufficient to make it Tach up to avoid the Wet Stack problem, what do you have to do?
Is that problem a big enough deal to make a guy think about changing the exhaust stack design? If it didn't go Up, YaKnow?

Dave, that’s kinda what I was thinking.  It’s definitely battle ready!  It’s cool that it runs on diesel and you have a single common fuel source for all your toys!

I have a little gas powered 3500w (4500w surge rated) generator.  It’s been a true blessing when we’ve had hurricanes and long power outages.  The longest we’ve had to use it continuously was Feb, 2021 when “snowmaggedon” hit Houston and knocked out power for 5 days.  We stayed around 15° for a week - extremely unusual around here.

I am able to run a small 6000btu A/C window unit in the main living area, deep freezer, fridge, TV, LED bulb lamp, and have power leftover to charge phones or use something else small.  I have to turn off the TV or AC to use the coffee maker (gotta have coffee!).  Anything that “makes heat” sucks some power (you know that).  I’ve run the toaster oven and microwave in a pinch and you can hear that engine chugging right up to the 4500 surge rated power.  We don’t use those anymore - I’d rather not blow the generator and lose AC because somebody wanted toast or something.

Cool project!  I like that BEAST!  Hopefully you rarely, if ever, have to use it!

Thumperpaul:

I am not exactly sure how much power I need.  These military generators come in a 3kw single cylinder version with a Yanmar air cooled engine, a 5kw twin with a Lister-Petter designed water cooled engine built by Onan, and a 10kw version with a 4 cylinder version of the Lister-Petter engine.  I believe the 10kw is just too big for our needs and would be wasteful of both storage space and fuel.  I was not sure the 3kw would be large enough to run our furnace if we needed heat.  I will give this 5kw a try and see how it does.  

Most of our power outages are short term and only last a few hours.  We have only experienced one long power outage and it lasted a bit less than a week.  We had a hurricane come through many years ago and it knocked down a large Maple tree in a neighbors yard that took out the power lines, and the power company could not restore the lines until the neighbor got the tree out of the ROW.  During that outage we had a gas 7,500 watt generator and it could easily power everything we needed (we did not run our 3,850 watt electric water heater and would go to my office to take showers).  To run just the fridge and freezers to keep our food fresh only requires the generator to run 30-40% of the day, and we could get by with a much smaller generator for that time as those appliances use 300-600 watts each.  There are small 2kw diesel military generators that look just like the normal contractor style generators that could do the job and only use about 1/3rd gallon per hour.....I may watch and see if I can find one of those at a good price.




JOG:

The solution for the wet stacking problem - is to make the generator work a bit.  When folks start the generator to keep it in operating condition and ready for an "emergency" - some of them don't hook up any load and then engine just doesn't work hard enough to get up to operating temperature.  The condition not only affects the exhaust - the piston and cylinder are also affected.  The solution is to hook up a load and make the engine work a bit - they recommend a 50% load or more and let it run for an hour minimum.  For this generator that would be 2,500 watts or more.....just a couple of small space heaters.  I don't know how often it needs to be run - once every couple of months might be fine as long as the batteries are put on a tender regularly.

The original generator has large terminals for hooking up the electric to provide power to something - the only outlet built into the machine is a double 110V outlet with a 10 amp limit.  The previous owner installed a 50 amp outlet on the side of the machine - it is gray and doesn't really match the military theme.

I bought some paint to cover the gray on the outlet and make it look more appropriate.  The original paint has bleached out a bit from sitting outside for 20 years - however the new paint matches better than the gray did.

The little cover gets bolted onto the top of the cabinet with a rubber gasket in between.  I will wait a few days for the paint to cure before I install it.

Your attention to detail amazes me, Dave!

The 5kw seems like a good size.  Good balance between ample supply and fuel consumption.

I need to go look at your other post and see how you’re doing with the pesky oil leak.

That has been on hold for a while........I need a good clutch cover to polish up and install.

That’s what I wondering…if you got a new cover installed.  Winter project.

What is the big solenoid with the bellows and the arm going to the left? Looks a lot like a kill.

If you're running it but the load is insufficient to make it Tach up to avoid the Wet Stack problem, what do you have to do?


The solenoid with the bellows is the fuel shut off.  When the power is on it pulls open - shut off the power and it closes and shuts off the fuel flow.

The engine always runs at 1,800 rpm to provide 60hz of power.  The throttle opens up when a load is applied to maintain the 1,800 rpm.  You need to have the throttle opened up enough that the engine makes some heat in the cylinders and exhaust.....running the engine without any load just doesn't get things adequately hot to burn the fuel properly.  Never had this problem with any diesel tractor, car or truck - but it seems to be an issue in generators that run at constant speed (if they are not properly exercised with a 50% or higher load).
