I use the Kat's brand; It's a good brand, but there are also others. I use a 250 watt unit on my hummer oil pan (2 gallons). Never have an issue starting it in cold weather, but the lowest I have seen here, north of Flagstaff is about 0F. If you get the pad style, make sure you follow the...

You can also pull off the fuel return line at the tank and point it into the tank fill opening (you might have to add a short piece of hose). See if fuel comes out, but stops flowing when the machine starts to droop. Then you will know if its a fuel delivery problem. Any chance the pump is...

The 2870 will output 70 amps, before it will safely shut down on overload. I have never measured my 802a starting current, but it might be enough to get it started since it is a small engine. Not sure about the larger 804A. (Has anyone here measured the starting current on an 802a while cranking?)

Since 3 phase works good, it is not a generator problem. Did this generator ever work correctly on single phase? Sounds like a wiring or switch problem. Based on how single phase is derived, it could be that one of the windings is reversed or disconnected when the switch is set to single phase...

I store my diesel in MFC's, with Biobor and PRI-D added. I usually rotate the fuel at 5 year intervals, although I tested one by keeping it 9 years, with no problems. Water, heat, oxygen, and certain metals are the enemy of diesel (and other fuel as well). Open tanks that can breath are the...

How do you know that the generator is the problem, and not the air conditioner? I spent hours trouble shooting a motor starter / motor circuit once, only to find out the device connected to the motor had mechanical issues, causing the starting overload. Can you connect another large load /...

Ignore my previous message. I read 831, not 813. Should have looked at the posted TM number.

No sealant is used on the headgasket. Just make sure all your surfaces and gasket are absolutely clean, then evenly torque the cylinder nuts. I don't like to go directly to the final torque. I usually go to 15 ft/lbs first, then to the final torque (same as the Yanmar manual).

Do you have compression? Can you hear the starter motor bog down on the compression stroke, or does it just whine like it's turning easy? Can you feel air blowing out the exhaust while cranking? If so, can you smell raw diesel? Is the fuel good?

Run your engine with the discs off to see if the RPM comes up. It won't hurt the machine to run without the discs.

Since both gauges are not working, there is a possibility that the set is wired wrong, or has been "re-wired". Check your voltmeters with a power supply, or a 9 volt battery to se if they work. Don't check the load gauge with a battery or power supply. That gauge has a 50mv full scale...

I use a surplus Fostoria industrial heater just like this one - Surplus Fostoria FES-1524-1A Space Heater (Not sure if I can post the complete link, but this one is on GovPlanet right now). This is a 15kw 240v single phase heater. The heater consists of six 2500 watt heating elements...

If it is the round filter mounting plate that attaches to the air preheater, you can just get a piece of eighth inch aluminum and make your own. It doesn't even have to be perfectly round. Drill enough holes for the engine to get enough air, and leave a strip of metal across the center to attach...

You will also need an upstream regulator on the cylinder, to drop the pressure to a level acceptable to the purge regulator. The purge regulator most likely cannot handle the 2200 psi from the cylinder directly.

Same problem on mine. Original, with 500 hours. I caught it before the sparks flew, while inspecting the machine with the top off. I used fuel hose to sleve the wires, and wire ties to hold them together. The insulation was chafed about 1/2 way through on one of the wires.

Nice looking control panel. Here is my 2 cents worth - One reason I have a MEP-802 and MEP-16's and 531's is because they are extremely simple and easy to work on, which makes them reliable from my point of view. After working with fancy computer controlled generators for many years, I prefer...

Don't know if it's the same as the 803-A, but here are the dimensions for the spring on my 802-A. Measured with calipers. Wire diameter - 0.088" Number of turns - 9 1/4 Small ID - 1.685" Large ID - 2.610" Height - 3.43"

I cut that part from a 1/8" thick piece of Silicone sheet gasket that I bought off the internet. The original gasket appeard to be fiber reinforced, but the plain Silicone sheet I used seems to be working fine. P.S. I currently have the top off my 802A if anyone needs any dimensions of any of...
