Your last generator Maintenance Run

[Industrial Toys]

Is is decent quality? I have seen those Yanmar clones from HF, brand new, on YouTube, just glow red hot and self destruct.

Did it ever run well? How old is it?.

EDIT: I saw your other post. Fuel filter looked bad in what way?

As for the Diesels not using more fuel under load. That's just not possible. Any diesel generator I owned, always started to snort under load and drink more fuel.

Sounds like those people that always claim they can get someplace in a ridiculously short time on ridiculously little fuel. A friend always claimed what good mileage his latest truck got, stating the fuel gauge as it used a quarter tank, or something, and I have told him a hundred times, the gauge is not linear!

There is a tread on here somewhere about gray market generator motors and I can't seem to find it any help ??? What I have is a Yanmar clone 189f motor in my generator that won't stay running. All new filter and fuel lines, I bleed it and all is fine at first then after about 3 sec. it starts stumbling and rpm drops,, like it's running out of fuel??? Any help would be appreciated ?/QUOTE]

Diesels add fuel to an essentially unrestricted air supply (not counting supercharged systems, which is a negative restriction). The governor will keep adding fuel to keep at the set RPM regardless of load. The amount of extra fuel required for additional RPMs at no load is pretty minimal. Load will dramatically increase the fuel consumption.

Gasoline engines on the other hand require a stoichemetric ratio of fuel to air. The throttle throttles (restricts, strangles) the incoming air at low RPMs so that the proper fuel to air ratio is maintained. Because of those inefficiencies gas engines are much less efficient at partial "throttle".

So in theory a gas engine shouldn't use to much more fuel defendant on load. Diesel on the other hand will vary fuel consumption significantly based on load.

I'am no mechanic but did you install fuel line in same original rouiting position ? Also have you tried starting it without fuel cap ?

 

[LouNY]

If the filter was real nasty pull the line off leaving the new filter see how much flow you get, then remove the line to the filter and see how that does.
You could have sludge or algae in your tank.
Also check that the return line to the tank isn't plugged.

Yes thanks..

Yes thanks..

Flow check like Lou said - tank screen or petcock obstruction would show there too.

Air filter OK, no mouse houses.....

Once the simple things are checked like plugged filter or line... it always comes down to internal carburetor corrosion... see it over and over again with ethanol and seldom used equipment.

Just checked the propane tank levels. It's been a bit over a year since we added the 2nd 500 gallon LP tank & had both old & new tanks filled.

Current gauge levels suggest we have approximately 700 gallons left between the two, so we used maybe 100 gallons over that 13 month period.

We use a propane furnace as backup heat source for the heat pump & the generator exercises once a week. We have a had a few short term outages over the period (longest was maybe 6 hours).

Unless we have a significant outage this winter, or a long stretch of really low temps, we may not need to refill next year either (my gut level trigger point for refill is in the 5-600 gallon neighborhood).

February like Blizzards here! DANG, I wish the power would go out!

 

[ultrarunner]

At the cabin... we had auto fill for the 500 gallon tank and would go through about 350 gallons a year.

When the bear took out the regulator and the gas escaped... we went one winter without and saved about $900

Since then we use about 40 gallons mostly in the summer for hot water which no longer meets the autofill contract.

Thing is Propane Company says they cannot fill tank without a $100 system check if valve has been turned off or tank is empty...

At this rate we might not see them for 10 years!

I turn gas off and on all the time... especially when property is vacant... guess you have to be qualified to turn it back on?

WE own the tank and have had to prove it twice in the last 50 years... don't know what it is with propane suppliers losing paperwork.

Is the Bear still alive ?

 

[ultrarunner]

Yes... I even saw the bear several months later and it did a lot of damage in the area but is protected...

My neighbors home was trashed... bear broken in and destroyed it...

I question why law of Fish and Game can't shoot it... they said their hands are tied... if a bear becomes a problem they may relocate...

And it has been an ongoing problem... after all... people are in bear habitat... right?

Yes and they where there before 100 per cent no doubt . :thumbsup: I live way out northeast of Naples , Fla 34117 and for a place way down almost on end of the peninsula you would not believe the amount of black bears we have here . They do the same around here , tear stuff up been known to get in houses etc . I enjoy seening them and glad also they try to tolerate us humanoids .

Well did my generators fall run up today, was saying last week I needed to run it and check it out, greased the PTO and checked gearbox last week.
Put a bit over two hours on it today when the power went out.

Quite economical..... esp. nice w. no storage (lifespan) issues :thumbsup:.

Careful what you wish for ! :laughing:

Had a brief driveway chat with my elderly neighbour yesterday. She knows I'd help her out during an outage, but commented she's getting her son to research a whole house auto generator for her.

She's very resilient still, but has grown really concerned about her declining husband who is still in the house. He's under proper medical care, but she doesn't want to face transporting him somewhere in the event of an extended outage. (We've had a few interruptions lately, and as close as she is to me, is on a different feed that seems to go down more often).

Reliable electricity is very convenient..... that chat reminded me that it's absence has much more impact on some people than others....

Too much of a pain for many people, but how about transporting your own 100# tanks ?

I see an occasional pu at Costco here, with 2+ 100# tanks for fill. They've usually got the best propane prices around.

Good stuff..... that's helpful of your local utility..... maybe you can ask them to call IT's utility and get them to flip the Big Switch for him !

I have not seen a Costco with Propane but have not looked for it...

Wouldn't be a problem putting 100 gallon tanks in the trailer... I do think I would run afoul of some regulation... a friend had a bunch of 5 gallon tanks to exchange and was told he had too many and would need placard... or something like that.
