You did all the work partner!! We were just looking over your shoulder.

That could be a fuel problem. A restriction, or lack of fuel pressure. Describe the surge. Is it a short oscillation, without repeating itself? Or more like a "hunt", short often repeated? Or long, drawn out oscillation?

Possable. Move the rack back and forth, then take another look. Sounds like you have it under control. Keep up the good work!

Might be able to tell you what unit, and if you give me a pic of the data plate I might be able to tell you where it was built.

Chris, If the set is 15 years old and has 22 hours and looks like new, then it probably went through Tier 2 RESET. As I remember, the rubber baby bumpers, (front and rear shock mounts) were an automatic change item. So if they are cracked, someone forgot them, or the mounts went south real...

Right on! Step for step. That's how it gets done. So whats next?

This is the WORD from Lister Peter. Just found it in my junk. Hope its readable.

Different subject, but as long as you have your head stuck in there, check the engine and main gen shock mounts. TM 9-6115-641-24P,figure 23, item 9, and figure 26, item 10. See if they are cracked. If the cracks are deeper then 4-5 milameters, you need to keep an eye on them if running...

Fuel pumps jumping off the rack was one of the worst problems the 802 and 803 ever had. For years. When inserting the pumps, be very careful. When they are just about fully in, twist them a tad right and left, to feel if they are in the rack. You can also move the fuel linkage, (lever...

Korgoth, Since you are looking into your set deeper then skin deep at this time, here iare some observations on the fuel tank of the MEP 802 and 803. The tank is where it all starts. Good clean fuel, much less trouble with the engine. The big difference between you and the Army is that the Army...

Keep in mind, these sets are not new. And many were any number of times down range. Then some of the TIER repairs were done by people who had NO IDEA. So yeah, a lot of "Field fixes" were done. Thats what kept me very much on the road for 8 years here in Germany.

Try this trick. With the engine running, loosen the clamp for the injector/Pump is just a tad loose. Put a wrench on it and turn it a hair right or left. Just a tad. See if the engine runs smoother. Then try the other injector/Pump. Got this idea/trick from the very best LAR I know. He used it...

Thanks, The data plate can be enlarged and the serial number cross referenced to see where it was last worked on. Sometimes when it goes in for tier 2 work, it doesn't get a data plate. Supposed to, but it happens.

My mistake Korgoth1, Its been about 7-8 years since I did this procedure, but I seem to remember that no two pump plungers was the same length. Having said that, I also can not remember one being to short. If I was still in the army, I would simply order another plunger, shim it properly and...

This is NOT normal. Read the TM and replace the shims correctly. OH, never seen 5 shims on a injector before. When it was removed before, It could have happened that the shims from one injector remained on the engine and the shims remained on the other injector. The pumps were switched, thus all...

Greetings! I am new here. But worked my entire 20 years in the army with power generation. I will be reading up on some of the threads to get up to speed. I have seen several times the ground wires burnt on a gen set when someone slaved it off incorrectly. When you switch the plus and minus...
