I have been a little concerned that my Genset on my RV is smoking too much. It is black smoke, not heavy but you can see it. The heads over on the RV site say it should not smoke at all. Well I thought the usual suspect would be a dirty air filter so I took her out and checked it and it did not look especially dirty but I thought I would just order up a new one and change it.
I went on line looking with no success at all locating a filter.
It is a Hatz filter #0140-4151. I could go to my local Onan dealer but I really don't have the time to go when they are open.
Anyone have any suggestions? The generator only has 127hr on the clock. |

I finally got my filters and installed a new one. I was a bit skeptical as the old filter only had about 137 hours on it and did not look to be restricted at all. Well, it must have done the trick because I ran the generator yesterday for the first time since I changed it and it operated for two hours with almost no perceptible smoke and little odor. Thanks for the help guys! |

Boy do you have that right. A diesel will suck your hand into the intake!
I once had a 7060 Allis (160 pto HP) on the dyno turning up the fuel so the owner could pull it in the dual wheel class at the Shelby County Fair Tractor Pull. I had the top off the Roosa Master Injection Pump, out in the hot sun, and I was turning the engine over by hand to line up the adjustment screws to crank up the fuel. Well, I got tired and had the bright idea of using a clip on starter button to bump the engine over.
Low and behold, the engine fired up and without the top on it, the Governor didn't cut the fuel back. I had a run away engine. Bill Moore , the owner of the Allis dealership grabbed the intake hose and squeezed it as hard as he could which brought the rpm's down a bit and yelled at me to do something because he couldn't hold it much longer.
My brain was if HIGH GEAR!!! I stuck my finger down into the pump and pushed on the metering valve which killed the engine.
All I could think of was the rods coming out of the side of the block which I was standing very close to...
Then Bill and I went and changed our uniforms... lol  |

Years ago when I worked for Servtech, I was visiting one of my crews that was hydroblasting in Ciba Geigy. It was a 10,000 psi hydroblaster powered by a big blown GM V6 diesel. They were running low on fuel and when the diesel arrived in a 55 gal drum the driver had omitted the drum pump. The service engineer got the great idea of using the intake to provide suction to start the syphon. I advised against it but he remover the air cleaner off the top of the blower and cupped his hands with the hose over the intake. I could see the line sagging under the weight of fuel and yelled at him to stop but I am sure he could not hear over the roar of the engine. He finally removed his hands from the intake but I could see about a half pint of fuel spill into the blower. I knew that was not good and the engine responded with a tremendous burst of RPM and a huge cloud of black smoke. I leaped from the trailer and dove for cover only to look back to see my service engineer laying over the top of the engine with his hand on the fuel shutoff trying in vein to stop the engine. The engine raced uncontrollably for about 15 seconds which seemed like a lifetime. I was astounded that it did not blow the engine or blow the big roots blower off the top along with the service engineer. I think the only thing that kept it from blowing is the big three cylinder positive displacement pump that was under full load at the time. The engine finally shut down and the man with the shotgun three stories up, shouted over the railing, " what the hell happened!". The surge of power at the shotgun nozzle had actually knocked him off his feet. We restarted the engine and it worked the remainder of the night with no apparent ill effect. I was concerned about the engine so we reported the incident to the shop foreman. He thought we were lying stating that there was no way it could have happened without destroying the engine. It was a good thing it was a night shift at the chemical plant as the incident went unnoticed. Otherwise we would have been kicked out for ever. |

I would add that you can wash that filter. Use a mild detergent in warm water in a deep bucket & let soak a half hour, then slosh around in the bucket. It the water gets all nasty, dump & add fresh soapy water & do again until water doesn't look so bad. Sit it in the sun & allow to dry thoroughly. NEVER wash a diesel filter in anything combustible like gasoline. Just even a hint of gas in the element & the diesel will take off like a jet & nothing will shut it down till the fumes are gone, or the engine blows!
You got that right Daniel!!!!!!! Most people don't realize that a diesel doesn't have a throttle plate. You feed it fuel, and its compression will fire it.
Back in 1980 I added 50% methanol to my Allis 190XT's water injection. Not only did it give the engine a big kick in the butt and it hit 6,700rpm, it melted every piston to the point of filling the exhaust ports and up into the bottom turbo housing with aluminum. I had to drive the pistons out with the sleeves still attached. Used a sledge hammer to bust the sleeves off what was left of the pistons.
I submerged the head and turbo housing in muriatic acid to dissolve the aluminum from the cast iron..
50/50 mix was to much!!! :)
Man, I bet you had a cloud of acidic fumes towering off that metal!
I use it straight on little engine journals, but you're talking drops, not gallons!
Yep, for those that don't know, the reason diesels vent their blocks to the atmosphere is because they'll take off like wild on their own oil vapors if vented to the intake. |

Gee, Daniel, thanks! I used to be able to just google anything I wanted and I could find it. Now there are a ton of sites screaming "look at me" and when you visit you find that they haven't a clue what you are looking for. I often have to dig into the 2nd and third page before I find a lead. I spent many hours looking for this and could not find. Kinda pricey but at lease it is a source. |

Gee Phil,
It says it's a Diesel... My Grasshopper is a diesel and it smokes a little..
I wouldn't worry about it.
