    MEP-112a to MEP-003a conversion 400Hz to 60Hz

    Thanks for the wiring info Guyfang. I finally got the generator back together. But, it doesn't put out any power. The good news is it started up and ran fine. I tried holding the start switch to flash the field, but still registered no voltage out. I started going through the troubleshooting...

    MEP-112a to MEP-003a conversion 400Hz to 60Hz

    I painted the generator end and had to drill out two bolts and re-thread the holes for the end cover. Next I put back the supporting frame then the output box. Leave all the bolts for the framework loose until you get the output box connected to the frame, it was a tight fit to get all the holes...

    MEP-112a to MEP-003a conversion 400Hz to 60Hz

    Thanks Guyfang. I had read the TM but forgot the flywheel bolts. I would suggest printing the appropriate pages and checking them off as you go. I edited the above procedure to specify which manual has the instructions and added the part about removing the flywheel bolts so I don't confuse...

    MEP-112a to MEP-003a conversion 400Hz to 60Hz

    I actually read in the other thread that they tried to adjust the RPM while the 400Hz generator was intact. The MEP-112a runs at 2200 RPM but the MEP-003a runs at 2000 RPM max. I was not sure how would be a good way to measure that, so I tried a photo tachometer on the generator fins (removed...

    MEP-112a to MEP-003a conversion 400Hz to 60Hz

    I found a great deal on a MEP-112a generator last summer. The seller included a 60Hz generator head from a MEP-003a generator for converting it over. I researched it and discovered that I would also need a different control panel and output box as well. I have a non-running mep-002a and found...

    Utah HMMWV recovery, Helmet Hard top install, and build.

    Long term goal would be to get Baja TA replacements for them. Until then I will check them over thoroughly and keep an eye on them. I was mostly curious if a MT would be fine as a spare if the MTRs were on the truck. It's also interesting to hear other people stories about the MTR tires, seems...

    Correct, that tire is definitely shot. If the other MTRs do not have any sign of cracking and are newer are they still at risk just because of the age? I've had plenty of MT tires much older that never have a problem.

    Utah HMMWV recovery, Helmet Hard top install, and build.

    I'll post more pictures of the helmet top tool box doors soon. It looks original to me, maybe an early model or something. I'll see if I can find the original sticker with NSN on it. I got caught up in the excitement of finding the 24 bolt rims and Goodyear MTR tires locally. The spare tire...

    S-250 Shelter HMMWV trailer build M1102

    I'd been putting off moving the shelter to the HMMWV trailer but decided now would be a perfect time. It was a great example of how some people can social distance while not feeling like it's the end of the world. One of us revved up the crane, one back the trailer under the shelter, one held...

    S-250 Shelter HMMWV trailer build M1102

    A while back I recovered an S-250 shelter. I'm finally back to the project and working on it. Here's a couple pictures of the shelter when I picked it up. It had some potential but needed some exterior work. We worked on the roof and got a first coat of green paint on it. The inside has...

    Do you mean the tool box doors on the hard top itself?

    Utah HMMWV recovery, Helmet Hard top install, and build.

    I finally had time to work on the HMMWV again. I have added a roof rack, it was originally from a jeep but was a larger model. I'll add some pictures of how I did that. It's getting cramped inside the HMMWV,so I decided to move the hi-lift jack up to the roof rack. My next project that I...

    Utah HMMWV recovery, Helmet Hard top install, and build.

    Hello I was out looking at the hitch today. I have the airlift bumper, the reinforcement plate and the receiver hitch. On mine the cotter pin did make it in the original hole. I left off the plate with the safety chain hookups and the thin plate that the pintle swivels against, the two added up...

    MEP-004a Generator runs but shuts down no fuel pumps run

    I know how everyone likes details, so I'll post up some measurements I took. At the connector that plugs into the float switch I have 25 volts on pins A and C. On pin D I have 338 ohms to ground. On pin B I have around 300k to 8.5 Mohms. On the sensor itself, I noted the pins C to D appear to...

    MEP-004a Generator runs but shuts down no fuel pumps run

    Hello I was checking out my MEP-004a generator and it started right up but then dies. I noticed the low fuel light came on and it ran for a couple more minutes with the battle short switch on. I had been reading up on the mep-004a threads and had a few ideas of what to check. The main fuel...

    Trailer Mounted CTMGSA-15 generator

    Thanks to those who helped me with info to get this runnning. I was able to get it fired up. I'm in the process of adding a Solargizer to keep it ready to use. I still need to gather the fuel filters and change those, but it is running well. As I work on it some more I will add more pictures.

    Hunter H1 heater engine and shelter USAF

    Hello I picked up a small trailer mounted H1 heater this summer. I believe it was an air force unit used to preheat engines and shelters. It is NSN 4520-01-135-2770 P/N: 8227100 manufactured by Hunter back in 1983. It uses a single cylinder lister diesel engine to drive the burner unit...

    Trailer Mounted CTMGSA-15 generator

    I finally was able top pick up the generator. When I went over the first time we noticed someone there had ran into the coupler and it was not safe to tow. True to their word he repaired it so it functions well and I was able to pick it up. I've found Plan-B supply to be honest and a good group...

    Identify this generator trailer AN/MJQ-32 Dual 3kw Hello I picked up an interesting trailer the other day. I've seen trailers with dual 3kw Mep-701 generators, but this one has a bunch of extra brackets mounted to it. Does anyone know what else was on the trailer as used by the military...

    Hello I just won the auction on a nice looking ctmgsa-15 kw generator. I'm very excited to get it going. I've been looking around cannot find a manual on it. Could anyone please help? It looks like a great unit. I found one of the smaller 5kw ones a few years ago and really like it. Thanks to...
