    Yet more drama with the 003

    Yes, the glow plugs are in the pre-combustion chamber where the diesel is injected. As long as the fuel cut-off solenoid has pulled up (energized) and the engine is just at cranking speed, maximum fuel is injected. This is why the engine smokes on startup. The governor pulls fuel back as...

    Yet more drama with the 003

    Glowplugs working? Sounds like you have flooded the engine with all that priming. This will make starting difficult. Disconnect the engine stop solenoid (just one wire) and all 4 glowplugs (remove and retain copper sealing washers). Charge batteries and spin it 15 seconds with the starter...

    Anyone know what this VR board fits?

    The -24P shows the regulator part number 72-5338 corresponds to NSN 6110-01-095-7440 made by FSC 30554 (MEP-DoD)or part 332-2285 made by FSC 44940 (Onan). If the generator's data plate is other than Onan, the original regulator was probably the 72-5338. The 003 uses 72-5020 by FSC 30554, NSN...

    Pros and Cons of zipper boots

    Silicone isn't too tear resistant. Sure, more resistant to oxidation but less resistant to tearing. Now a Buna-N rubber one-piece or EPDM rubber would work well. As would a Aramid-fiber reinforced ether-based polyurethane.

    Pros and Cons of zipper boots

    With modern silicone sealants, there is no difference in water-tightness or sealing when done correctly. Just make sure the zipper remains clean (masking tape?) and get some silicone under the zipper where the bands clamp. Zippers to the rear. Also, clean the contaminated grease under the old...

    Generators for Dummies

    Since the TM isn't available for the whole set, use the following: Generator head:http://igor.chudov.com/manuals/Military-Generators/MEP-016A/TM-5-6115-271-14.pdf (ignore the OA-32 milstd. engine) Engine only:http://dawinfo.com/L-A-Service-Manual/L-A-Manual-Complete.pdf Now the fuel subsystem...

    Generators for Dummies

    If the generator is under 5kW and connected by plugs only, no grounding is needed per NEC. If this is used in the Texas Hill Country, grounding might be impossible as soil depth is often nil and limestone solid. The MEP-016s have exposed load terminals...I will probably build a genset-mounted...

    Generators for Dummies

    Oh, Boy Scouts? As an Eagle Scout in the area with a bit of generator smarts, I will volunteer to help out. Without bribery of that addictive caramel corn nut mix..:shock:. Good thing that stuff is $20 per can, I would be HUGE if price were less:deadhorse:

    MEP 002A -- Failure to Shut Down Properly

    The engine shuts off by the solenoid pushing the control lever down, over-riding the governor's spring. Either the spring link is dirty or the solenoid's spring force is weak. Either way, spray some Berryman B12 over the spring link (telescoping link between governor arm and injection pump...

    MEP-002A meter overhauling

    And just today, the low oil pressure switch came in. No longer running the generator with the DA2404 having X, red X or circled red X in the status column :-P. So I ran it up, loading it with a 14" abrasive chop saw cutting railroad rail :shock:. Percent rated current meter in the 50% range...

    MEP-002A meter overhauling

    The issue is water and the design of the meter face causes it. Specifically, the bezel which extends up 1/3rd the way up the glass. There is a little drain at the bottom which plugs up, then the bezel traps water between it and the glass. Even the bias screw can be a leak. The meter's...

    MEP-003A Saved the Day

    All fuels do this. But the slime needs water so keeping the tank free of condensate by keeping the tank vent closed and the tank full goes a long way. Monthly inspection of the tank and weekly PMCS will keep the fuel in good shape. Rotating fuel stock is even better. The fuel tanks have...

    MEP-002A meter overhauling

    Yes, I noted that after contemplation and a night's sleep. Fired it up today, set the engine speed via my digital multimeter, then adjusted the bias screw to match the meter to the actual. Then ran it up to 65 and down to 55 Hz, spot on. Happy camper I am. 20 minutes of work and $19 nets me...

    MEP-002A Hidden battery "jumper" cable

    Slave cables are heavy and being made of copper, expensive. They don't last forever, being abused by the typical disgruntled service member who had to go sign them out from the tool room. And because they are expensive, they get scrapped rapidly by the DRMO carrion vultures aua You don't need...

    MEP-003A Saved the Day

    Fortunately, the injection pumps aren't all that picky as long as you are using commercial #2 ULSD. The tappet and cam are lubricated by engine oil, other injection pumps are lubed by diesel and have issues. About the only thing lubricated by diesel would be the injection piston and its control...

    New from Texas

    Did you say "beer"? I can be talked into working on an M35 with those words:beer: References? Yeah, I've a few here:driver:. My specialties are brakes, wheel bearings and injection pumps. Funny truth, after doing brakes on an M35, doing brakes on a car seems like a joke. Got another puny...

    MEP-002A meter overhauling

    The meters on my 002A were in sorry shape from water intrusion. I couldn't repair the frequency meter as it was too far corroded. The dial was fine... I found a 200 microampere full scale (fs) meter that would fit but it was for some other application. Price was right at $19 where others...

    re-wiring my MEP-004a for different voltages, including single phase

    Should be specified in the -24P TM. Getting to this voltage droop, remember Ohm's Law. You have twice the impedence in the zig-zag leg (ohmic+inductive, for the most part, you can assume Ohm's Law). If this generator's VR uses voltage of a single winding for output measurement, if that...

    Frustrating oil leak Mep-002a gear cover and oil seal

    A 2-bolt puller with 5/16x24 tpi bolts works great. I got mine from NAPA. The voltage regulation issue might be from excessive load. Unless it was frequency related.
