For the CAD guys, I made package models of the -802 and -803 to use for a project. I'm sharing them on GrabCAD if you have a need. They are accurate enough for building a trailer or mounting platform. MEP-802a MEP-803a

Does anyone know how many 802a's and 803a were produced?

You will hear it here sooner or later, but have you downloaded and read the TM for your 805? I know it sounds like an internet cop-out, but those manuals are really good at diagnosing normal issues. That said, you mentioned you have voltage to the K2 relay. I assume that is power to the...

This thread is a blast from the past. I'm up to 4 units now, haha

Thanks Guyfang for helping me understand how to read the harness diagrams, I'm glad I ordered the right housings. Here is the parts I ordered: Fuel pump connector housing: Molex 03-09-2022 Harness connector housing Molex 03-09-1022 The pins were the hardest part to figure out. I ended up...

I'm not knowledgable about 501A's specifically, but that looks like the Field coil connector. The field coil generates that magnetic field that drives the stator coil to make electricity. If there is no power to the field, you will get no power out of the stator.

Unfortunately I dont even like these Molex connectors, but I wanted to return this unit to a OEM condition, giving me the abilty to swap pumps easily if necessary. From the TMs, it is easy to track down the housing numbers, but the pins are proving to be more trouble. Worse, the datasheet for...

One of my units is missing the connectors for the main fuel pump, both on the pump and harness side. I have tracked down the part numbers for the pump side housing and pins, and the housing for for the harness side, but I'm struggling to identify the correct P/N for the harness side pins. Any...

Have you been around when the unit shuts off? Does it puff grey smoke when it quits? It seems unlikely since the unit runs for a while, but a stuck pressure relief can cause the oil pressure to spike, which will cause the lifters to pump up and hold the valves open. I would run the unit and...

I don't have direct information regarding the MEP's here, but I sure the MIL STD could be dug up on Google. Generally, EMP testing would be done over specific frequencies and field strengths. EMPs happen in different stages (E1, E2, E3) and based on publically available reports, most consumer...

I would also add that small (5kW), ruggedized, 1800 rpm diesel generators with brushless genheads are basically non-existent in the commercial world, and would be very expensive if they were common. So I take these prices with a grain-of-salt because the 802a fills a niche. However $7200 is...

I'm no expert, but asking price for a single MEP-802a in my area is $3500-$4000. $7200 for two with trailer feels like an average price for that package. Does the trailer have a clean title?

Wow. Just wow.

Haha, that is the truth! Maybe a small compressor or welder. I figured no one had done it, but worth asking.

Not so much a question of can you, but has anyone rewired a MEP-802a or -803a genhead for 416/240V 3ph operation? The genhead looks to be a standard 12-wire alternator wired as a Parallel Low Wye for 208/120V output. Typically these can be rewired to a Series High Wye for greater voltage. I...

That's a good bit of info I will squirrel away for later.

Great job on the radiator flap! That looks really good.

There is a MEP-1041 for sale in Iowa for cheap. Guessing someone didn't know what they were buying.

Taking rounds, that's some damage I haven't seen before.

I would almost guarantee there is a functional equivalent for that oil pressure sender for less money. If you are searching by NSN number, you are probably getting results for parts that meet every section of MIL-STD-810 and than some. There are pretty extreme temperature, vibration, dust...
