FYI, on an 802/803 you need 1/2" NPT. On the 002 and 003 you need 3/4" npt to screw into the machine.

Yes, I just ordered some parts from Ambac, so I will have some stuff on hand. I'll pull the pump out and see what happened internally. Should be fairly obvious once I get it apart. I've done a few of these pumps before, so it will be interesting to see what went wrong on this one. I'll post...

Hello Cord, I have 831A that was once doing similar things. It would randomly shut off after a minute or 2 and I would get over voltage and obviously low oil faults when it died. I also installed one of Kurt's controllers and it has been good ever since. A word of advise, when you install the...

Gunny, Guy is right, I'd get your batteries charged up and test your alternator. If you aren't getting close to 28V out of it, it is bad. You can get a replacement for $180 but you also might only need a new regulator. I've occasionally seen them for $40, but few and far between. The TM tells...

This morning I took a few minutes to check the static timing and something is definitely wrong. With the #1 cyl. valves closed and the engine set with the pointer at PC and verified a 1/8" drill fits into the notch under the small screw, I removed the spring from the delivery valve and removed...

Hello guys, I have a question regarding an MEP-003A that I'm working on. It is a machine with 6 original hours on it, has been sitting a very long time. I purchased 2 of them on a M1061 trailer from a nearby municipality. I went through the machine doing all the regular pre-start stuff, flush...

I use Wix 51515 or NAPA 1515. I don't have any pics with me now, but I made 4 or 5 spin-on adapters out of 1" aluminum. Maybe took an hr. ea. on the lathe. Then used a 3/4"-16 straight thread X -12AN flare adapter to attach the adapter to the block ( 3/4" straight thread end ) and serve as the...

Thanks as always Guyfang! I will consult the manual as well....

You will definitely need to change out all your rubber fuel lines at a minimum. Most likely the well nut will also need attention. Also, keep in mind that biodiesel will cloud at temps as high as like 36F. So in cold climates running straight Biodiesel has other issues besides eating rubber and...

I've tried the NAPA P.N. that is discussed elsewhere on this forum, but it did not work well. Slightly too wide causing it to not seat into the groove correctly. Could not stop it from leaking no matter how many times I tried. I ended up buying a 5 pack from Green Mountain for around $15 or so...

Is there any specific information on the Diode replacement to repair a bad alternator that anyone can point me towards? I have a bad one in my parts stash that I would like to repair to make it a good one. I'd like to read up on it... If not I'll just tear into it someday.

Finally got around to messing with this thing again yesterday. I took the top cover off and got the governor spring out of the way so I could poke at the governor assy. to ensure it was free and not bound up somehow. Reassembled and confirmed that I could control the engine speed using the...

Hello, Have you done any service on the machine? Fuel filters, oil etc? and have you tested it under a load? I'd be curious to see if the frequency swing starts sooner and is more pronounced when under a load. My first thought is a fuel supply issue which will probably be exaggerated if you test...

Yes, they are about $75 for the NPT style, but... since you have some EMT tube in there too, the Universal flex joints for a car exhaust are only about $25 for the size you would need. Could weld it or clamp it in. But, as long as you're aware of the risk.... Regardless, you have an enviable...

That's one nice looking set up! I can't tell from the pictures, but since you say you're getting a lot of vibration in the exhaust at the roof penetration, I assume you have it piped solid from the muffler to the roof? If so, that might eventually cause too much stress on the system and...

You can ohm out the wires on the sensor and if it appears the sensor is showing no fuel, try loosening the large nut on the top of the sensor flange. This will allow you to rotate the float arm slightly left and right to make sure the lower float ( low fuel ) isn't touching the side of the tank...

Good advise Guy.... wish I read it before I installed it! I put it in yesterday and it runs! but I've got 2 issues to contend with. There is a very big fuel leak when running ( possibly an injector line seal as you mentioned ( I didn't know they only go in 1 direction ) The good news is that I...

You can also try unplugging the white connector on the back of the fault light panel. Unplugging it will actually bypass all the fault safety features.

Well, the pump is rebuilt. Made a few mistakes along the way that caused me to have to back up a couple steps, fix, then continue. But all in all it was pretty easy. As soon as I get time I'll reinstall and see if she will fire up!. The stuck plungers were without a doubt the reason it wasn't...

Also, we need background history on the machine. Has it ever worked correctly for you? What was it doing that caused you to replace the AC regulator? Was it doing the exact same thing before you replaced the AC regulator? When you loose AC output do you know how long it takes to get power...
