Fuel Solenoid

[Triton]

Had to use my MEP 803 after some bad weather in Houston, went to shut down generator to check the oil and make sure everything was good. The generator was running perfectly but it would not restart, I noticed the fuel solenoid in the forward position so I pulled it back and it cranked right up. Some times the solenoid pulls back slowly and sometimes not, the linkage does not seem to be binding so I guess the solenoid is dying. Where can I find a replacement? Would a used one from a parts machine be good? It looks like Amazon is Chinese junk
Thanks

I would undo the linkage from the rotating arm on the block, and see if the spring freely pulls closed. Then articulate it fully open, and see if it naturally snaps back closed. If it doesn't, I would start to suspect a sticky metering pump (and possibly not the solenoid).

Do you have access to a parts machine?

 

[Triton]

I don't have access to a parts machine, how would I address a sticky metering pump?

By removing it from the block and soaking it in carb cleaner. Its not terribly difficult. Get well clear of the outage and tackle it then when you have a few days.

 

[Triton]

Ok great! Is there any threads on doing this?

I have two parts machines that are reset units and they both have chinese fuel solenoids uncle sam bought

I use Hot Shot's Everyday Diesel treatment in my truck, would that clean up the sticky metering pump?

It won't hurt cleaning up the internals. Sometimes its external buildup due to lack of use, settling of crankcase humidity mixed with oil residues, etc. Just let us know what comes of the freehand test on the rack movement first.

 

[Triton]

Well, still on generator power but I did freehand the rack today, it doesn't seem to be binding and it has worked twice today. They say power should be back by Wednesday, after that I delve into it some more.

Genset must be worth every penny right now

They are older so every creature comfort is appreciated. Neighbors are come over to charge phones!

So I got to look at solenoid more closely and I found that the lever is in the wrong position (see pic), this may be putting the solenoid in a bind. When I move it to the correct position the lever binds on the adjustment stops. My question is does the nut that is shown in my picture go between the solenoid lever and the shut off arm to keep it from hitting the stops? Checking TM

 

[Triton]

Ok, so checked the TM and there was a really good picture of how it goes back together, there is not enough thread to put a locking bolt on the back so I guess I'll use some lock-tite so it doesn't back out!

Here is a video on the injection pumps & how to remove them if you need too;

I'd just prime the system with ATF & let it sit for a while when you can.

If you end up needing a solenoid, let me know. I have multiple. Moisture gets into them and causes issues over time, especially if the boot has a rip.

Do you know of a source for boots?

I don't. I'm sure there is one out there, but I have yet to find it. Military didn't dig down that far, they would only replace the whole part.

There's at least one person selling good ones on the 'bay... the solenoid design itself is pretty common, believe the boots were advertised for a 12V Cummins.

My 802 came with the solenoid, blown apart on the floor of it cuz the hardware at the lever had come loose, and the boot was torn. Sticker shock at the price of a good one, and minor sticker shock at the price of a cheapo, got me looking for a fix once I figured out I had all the pieces still.

This what you saw?

LarryB's Replacement Boot for D610-A1V12, SA-2606-A and other fuel solenoids | eBay

See below. It also holds the plunger in the solenoid. About a 5 min job to remove and replace. Fits the following solenoids.

Same guy, I bought the one that says it's for SA-3765 & -3799 solenoids.
