Fermont 804-B Engine Control Module Needed

[WildernessJeep]

I'm looking for the Engine Governor Control Module for my 2010 Fermont 804-B with the Yanmar Turbo Diesel, NSN: 2910-01-371-4356. It is also known as a Woodward Controls, part no 8270-1003. I can't find it anywhere, and my generator is useless without it. Anyone have a lead on a cross-fit component or resolution?

Please be advised, you are trying to order the wrong Gov control unit, unless you are ordering for the MEP-804A. So tell me what you are ordering for, a 804A or 804B model.

 

[WildernessJeep]

An 804-B.

How is it not part 50, with the "YNN" (Yanmar) designation? Am I reading the manual wrong? Am I reading the wrong manual?

 

[Guyfang]

Your right!

I was looking at an old TM, and when I went to pop the pizza in the oven I reopened the TM file and saw I had looked at a TM from 2002. Sorry.

You can also look under the woodward part number, 8270-1003.

This is also a part number for this governor.

Yeah, I can't find that part either. GE aerospace makes one, too, but that's impossible to find as well. Any cross-referenced parts?

I just looked at all gen sets, 15-60 KW in the A and B models. That governor only fits that gen set. Its not used anyplace else. Is yours bad? Missing?

Mine is missing. It looks like someone tried to bolt another component in the same space before the govplanet auction to hide the fact that box was missing (not like I would have known anyways). I bought it not running on the cheap. Now I'm going through part by part, and noticed this missing. That'll cause it not to start, huh?

 

[Guyfang]

Yeah, a little bit. Everything was good with the A models, until they came up with the new engine. AND it needed a different engine. But for some reason it also needed a new GCU. Stupid. Have you listed in the want adds in the forum?

 

[Dewie38]

You could use the control unit from an 804A
We had to change engines because the Isuzu engine we were using became unavailable. (out of production) we had to change controllers because the actuators on the engine had a different spring tension and the controller wouldn't respond as the old one did.
It didn't have the same response time so the sets wouldn't pass the freq. and voltage response tests where the freq. had to recover within a certain time.
So if you don't care if the freq. response time is a little slower go ahead and get a controller for an 804A if you can.

 

[Guyfang]

Ah! The rest of the story. I only hear the CECOM side. This is good to know.

 

[Light in the Dark]

Yeah thats info you won't get anywhere else. Thanks Dewie.

Found a new one on the shelf. $12,997. Hard pass.

For an A unit, if you havent found it yet:

GAC MILITARY MEP 804A 805A 806A DIESEL GENERATOR GOVERNOR CONTROL MODULE ESD5560 | eBay

DOES NOT WORK FOR ANY OTHER GENERATOR MODELS. Hard to find part. In most situations you can buy a Square Trade warranty on the item for a small fee.

Please be advised, that there is another GCU with a different NSN that will also fit the A model 804A. It was the first generation GCU. The second one, NSN 2990-01-601-2478, (the one listed above) is a newer model, that is called a "universal" GCU. It fits the 804A, 805A and 806A. The old GCU, NSN 2910-01-373-2590 is also in EPAY, and about 200 bucks cheaper.

Should you choose to follow this rout, this is a handy document.

Got the generator up and running today!!! Started right up, runs smooth. Need to finish up a couple of wiring connections and get the distribution box connected up, but overall it sounds great!! Thanks guys!

What did you do to get it operational?

Replaced the Engine Governor Module in accordance with GuyFang's instructions. I still have a few connections to make for some of the other components, but the motor turning on its own power was enough of a win for me today!!

Awesome! I've been following this thread, glad to see you got it up and running!
