Battle-Tested Diesel Generators and Parts

Thanks for visiting Green Mountain Generators (GMG) – the US’s most dependable source for affordable military diesel generators and parts. Why do we specialize in these units? For the government or commercial customer, the quality of these units is unsurpassed. For civilians and small business owners, these units provide a bomb-proof solution at very reasonable prices. For all segments of our business, GMG helps establish a supply chain for these units to streamline the acquisition of refurbished generators and new parts. GMG is committed to establishing a comprehensive parts supply chain for the generators we sell and service. We welcome the opportunity to establish a long-term relationship with you, whether you are government, supply-chain professional, NGO (non-governmental organizations), municipality, non-profit or corporation. We have recently obtained approvals from the U.S. Department of Defense, the U.S. Department of State and the U.S. Department of Commerce (specifically, the Bureau of Industry and Security) to export demilitarized generators globally (with specific exceptions)

GMG’s Services Include:

  • Surplus acquisition services for large customers (e.g. acquiring multiple units at auction, logistics,refurbishment and delivery).
  • Sales of refurbished generators backed by our 90 day parts warranty.
  • Sales of spares and parts, many of which are difficult to source.
  • Acquisition and procurement services for government and commercial customers that require volume discounts and a large variety of products.

GMG’s Unique Capabilities:

  • 90 Day / 100 Hour Warranty: Another sign of the quality we put into every unit, is our 90 Day / 100 Hour Warranty (whichever comes first).  We believe that our refurbishment program is the very best in the industry and we are confident in our products.  If your product malfunctions within this warranty period, we will provide a replacement part for anything that malfunctions.  Shipping costs (outbound or return) will not be reimbursed.
  • Industry Leading Refurbishment Program: GMG has put together the most thorough refurbishment program for our units.  We ensure that all units are parts complete, functionally complete and all units must pass a very thorough load-bank test.
  • We ship globally: We also ship anywhere in the World.  Through shipping partnerships, we can offer nationwide and global shipping at very reasonable costs. To keep costs to a minimum, we typically ship to terminal locations throughout the US and World.  For additional fees we can also arrange residential lift-gate service (a smaller truck can deliver a unit with a hydraulic lift to lower the unit to the ground level). Additional fees apply for international shipping.
  • Complete Solutions:  GMG is committed to creating and offering complete solutions and will work with you to design the best solution for your energy needs, whether it’s in a remote jungle or for your home.  In the US, we are partnering with only the best service companies to offer on-site installation and maintenance of your unit.

    Not advised. You can look for an external frequency converter to take the power output and convert from 60Hz to 50Hz. A similar path can be made to externally convert 400Hz units to 60Hz units.

  4. GMG says:

    Unsure of what unit you have, but many/most military units are excited from the 24v battery source during start cranking. But to ensure the field is energized, you must hold the start/crank switch for an additional 5 seconds to fully energize the generator head. This is a common thing people don’t realize and is the simplest problem to solve in a no power generated scenario.

  7. claudiodelvalle says:

    Dear,
    On the MEP831A, is it possible to set or adjust the frequency operation to 50 HZ?

    Thanks

    Hello guys
    I have a 2006 15kw trailer mounted gen with 420 hrs on it. When doing to start on master switch all I get is a click from the injector pump. I can jump across the what I am calling the starter solenoid that is in the upper right hand fwd circuit box. I called Monday and left a voice mail.
    If I am on right path plz advise.
    Thanks, Ralph 3185052873

    All generators need manual shipping quote. Estimate is between $600 and $700 cross country depending on residential or commercial address and need for liftgate. Yes, we can send you photos, but we are out of stock right now. We can reserve the next MEP802A for you if you put a deposit down on it. All units are load banked and tested for leaks, poor firing, temperature, overheating, etc. If a pump is bad on a 2 cylinder, it will become obvious within 2 hour loadbank test. Please use our contact form to reach us.

  15. GMG says:

    All of our manuals for the kits are here: Remote Start Manuals
    Or send us an email via our contact form on the website and we’ll get your question answered. Please be as specific as possible as we may need to forward to the manufacturer.

  18. GMG says:

    Most loads can run on 208V. You need to check the nameplates of the loads you are running. You can also get 120v legs off of this unit as well. Typically 120v and 208v. You will need to consult an electrician to determine details of hookup, transfer switch etc.

  19. sherm says:

    I purchased a MEP-804-B, Under 100 hrs on a generator trailer. Runs like new. Di I make a mistake not realizing that the voltage is 208V? Can it be changed to 220V, or can I use as is for a back at my business?

    Thanaks,

    Sherm

    Hi I recently purchased a Auto remote starter kit for my MEP 803A generator. Yes I have down loaded the manuals. What I like to know is. Are there anyone that I can call for questions during the wiring process or is there a video to walk you through this process?
    Also which manual should I follow using a automatic transfer switch only.

  21. scichoski says:

    I am considering purchase of a MEP-802A with ASK. I am located in Los Angeles, Ca. Big purchase for sight unseen. Would it be possible to get pictures of exact unit I would be recieving and hour meter reading before purchase? Also description says that injection pump is tested, what type of test would that be? Is that performed on the machine? My zip code is 91789, shipping cost? Your website would not accept my zip code.

    Can someone please call me at 631-751-0460 ext.220, we are trying to use your web site and it doesnt work. looking at fuel injection pump.

  24. GMG says:

    You need to check the battery charge regulator and related connections. Sometimes the stator winding can be bad as well. We can get you both if needed.

  26. GMG says:

    Yes. Can you download the free manuals and use our contact form to send us a list of the parts required and we can send you an invoice and ship them directly from our Yanmar supplier.

    1984 MEP 003A
    UNIT RUNS BUT IT WONT CHARGE OR GENERATE.
    WHEN I PURCHACED UNIT I WAS TOLD IT WORKED FINE.
    IT WOULD NOT START WITH THE SWITCH AND HAD TO BE JUMPED AT STARTER WHEN I WENT TO LOOK AT IT. (UNIT WOULDNT START THAT DAY IT HAD JUNK BATTERIES AND WAS UNABLE TO CRANK LONG ENOUGH TO START ALSO IT WAS 15 DEGEES OUT WICH COMPLICATED THINGS I BOUGHT THE UNIT ANYWAYS)
    I FOUND THE START SWITCH PROBLEM WITH THAT WAS THE DIOD FOR THE START CURCIT WAS SOLIDERED IN BACKWARDS BUT IT WAS CORRECT ACCORDING TO THE WIRING DIAGRAM ON THE TOP OF UNIT. I FIXED THE PROBLEM AND IT STARTS WITH THE SWITCH NOW BUT I STILL HAVE THE GENERATOR AND CHARGING PROBLEM.
    ANY INFO WOULD BE GREATLY APPRICIATED
    THANK YOU

  33. GMG says:

    Only military batteries that are very expensive and hard to find will fit inside the unit. Best bet is to put 2 12v batteries in a battery box outside the unit and keep them covered from the elements. The bigger the better since you will be external to the unit, but make sure you use heavy gauge cables.

  35. Randy Dely says:

    I need some information on what size/style battery fits a MEP831A Military Diesel Generator.

    Thanks

  36. Arthur Kane says:

    I was given an MEP003A generator and it is in need of oil. Can you tell me what weight oil is used in this generator.

  39. gmg says:

    You will need 2 12v batteries to create 24v starting system. Bigger the better. The 24v military batteries are very expensive and typically not worth it. We recommend putting batteries in battery boxes to protect from snow, ice, water that can short them out.

  41. Jeffrey Roman says:

    My mp003 stop generating , it was working good the problem occurred when the battery make contact with the machine . I didn’t notice and started the engine immediately sparks happen then it stop producing energy. Engine is working fine. What could be the problem?

  43. Justin Miranda says:

    I’m looking for a radiator cap for a 2006 Mep-803a keeps saying sold out for the longest time.

  44. gmg says:

    You will need to check all the electrical circuits related to the shut-off and safety shut down. Voltage output should always be at rated voltage (120, 240) even with no load. The % output meter is different; that should only register a % when load is applied.

  46. Edwin Irizarry says:

    Greetings I buy in GL a generator 813 A 120 v / 240v /208 but it is 400hz i can not use it with that hz as I can change from 400 hz to 60hz if you can i want to know to do it

  48. gmg says:

    About $500 give or take. $75-100 can be saved by delivering to a shipping terminal versus residential lift-gate service. The engine is just that, only the engine. It does not have a generator head. Not sure what your application is on your RV.

    How much to ship to south Texas, and does MEP003A Remanufactured Engine NSN-2815010465862
    Have everything I would need to connect it to an RV

  50. rlcaruso says:

    recently purchased 831A, engine runs fine but cannot be shut off with switch or panic button. sometimes shows a voltage output on the volt meter and an output on the kilowatt meter with no load applied . any ideas ?

  51. gmg says:

    No, the ASK is additional (or you can build your own). These are all refurbished and tested (not rebuilt or remanned). CA would be in the neighborhood of $550 freight to a nearby terminal where you would need to pickup. We can most likely source a solenoid for you also if you confirm a part number. GMG

  52. Mario de Solenni. (707) 464-1494 says:

    Does the $2,999 price for 5 kw military he set include thevASK or is that additional?

    Are these new, rebuilt or what? If used how many hours on theme?

    I am very interested in obtaining one of these units. Where are you located & what would freight be to Crescent City CA 95531. I would appreciate a call to my home phone, 707-464-1494. I am 78, obviously retired & have had some experience with these units in power outages. They are very reliable and economical to run. I have one in my yard which needs a solenoid control unit. It hadn’t been run in several years but I’d bet that it could be easily be repaired if I could find the parts. I still plan on getting a new one but would like to know what the total bill will come to.

    A phone number I could call to get this information would be appreciated.

    I have a Oman 6.5 kW gas generator.I need the choke kit 1530429 do you have it or can you get it if so how much?

    We just tested inputting Washington as the state and zipcode as 99114. Make sure that you don’t have any extra spaces before or after the zipcode as that might be why the postal code is not being processed correctly.

  57. Cory Trost #BrimstoneFarmsL.L.C. says:

    When I attempt to type in state and zip code it says shipping is not available in this area. How can you accommodate my location of Colville Washington 99114?
