It looks easy enough, just 4 screws and maybe a new o-ring seal (I had it "professionally" installed by the rebuild shop when I had the pump rebuilt). I say professionally as they obviously did not read the directions even though I brought them a copy, so I had to go back behind them and...

I recently converted a somewhat similar (Allis Chalmers / Roosa Master - Standyne) commercial 24V DC control system 125KW Onan generator from mechanical governor to an electronic governor using modern off the shelf parts bought on ebay, etc. I think my total parts cost was around the same as...

Check the oil pressure sensor switch, I think these are wired reverse of most civilian units with the sensor switch being normally closed and opens with pressure, but I could be wrong on that detail. Ike p.s. the easy way to test this is to disconnect the wire going into the sensor see if it...

A couple of more things, base your choice of injection shops on reputation not on price, ask some of the local diesel shops who they use for injection pump work. Shopping injection pump rebuilds on price is like shopping for the cheapest dentist, maybe you get lucky or maybe you end up in a lot...

My gut feeling is your injection pump needs to be rebuilt, perhaps some of the gunk got past the filters. Ike

A diesel knocking could be as simple as a clogged injector or air in the lines. Ike

The only reason I caught it is we have a 125KW Onan connected 120/240 delta and I know its amp rating. Ike

Something does not look right there, according to my math 80% load on a 150KW generator at 120/208 should be around 416 amps. Ike

My understanding of the NEC (not a professional) is this would now be a NON-AUTOMATIC switch if it were not wired into a generator start circuit. This is a distinciton of difference from a manual switch, as the switch does not work mechanically. There is also a new NEC requirement that manual...

Yeah, this change in the 2008 NEC is a bit insane, but I guess I can see their point with non load shedding automatic transfer switches. You are in a situation where the load draw could be more than the generator can supply, which could easily result in a dead generator from melted windings...

The problem with BBQ tanks is freeze up, it is a simple question of is there enough surface area in the tank to boil off the propane gas when using vapor extraction. One possible option is to use liquid extraction forklift style tanks with a vaporizer. I suggest looking over at the smokstak...

Welcome to our (sometimes, often,...) happy little group It does look like a nice MEP-002a As to your pick up concerns, I would certainly strongly consider picking it. I have been lucky out of the dozen or so items I have bought from GL ranging from 30 pound to about 5,000 pound items about...

I think I should point out here that the MEP-002 and MEP-003 are not your typical 5000-6000 watt generators, for one thing most consumer 5-6KW don't have real voltage regulators (some more so than others) which means they suffer from large amounts of voltage drop when hit with a large load. By...

The -12 steelypip refers is the tech manual (the manual numbers tradiationaly end in -12 -34 -24 for operators/field manual, repair manual and parts manual) Whole books could and probably have been written on the concept of power factor, in its simplest terms power factor refers to if the the...

One more thing to check, see if htere is corrosion on the connectors on the back of the meter, etc. Corrosion will increase resistance and lower the voltage going into the meter causing it to read low. Ike

The big thing here is to get something that will run the welder, that means something that will accept the welder's sudden load all in one step. Ike

Carl, glad to see you could make it to this little party we are having. You left out one important thing on your example wiring, you need a way to also transfer power of the vital loads to your second larger generator in case the small one dies. It could be rather embarrassing to have TV...

Spedmonn, as you and I know, paralleling is possible, however the cost of safe paralelling gear is going to greatly exceed the cost of any home standby generrator. Even the relatively small military units that support paralleling are often used in such a way as to provide continuous power and...

Your fuel estimates are in the ballpark, at full load they will be a bit higher than your estimate, but not too much. If you are considering military surplus a 10 kw MEP-003A will likely do the job, just be aware they can be loud, if possible you would want to locate it away from your shop a...

I am all for the idea of having at least 2 generators, and prefereably ones that run on multiple types of fuel. As a practical matter people using generators (emergency backup ones or not) fall into 2 catagories, those able and willing to do manual load management and those that are not. The...
