Generator problem

[Fredkrueger100]

So I took apart my generator this afternoon. It wasn’t too difficult. I made sure to take pictures so I knew where to put stuff back. It has got to be the seal around the crankshaft. That is where the oil is coming out of when I run it. The seal doesn’t look bad but I have no idea what they are supposed to look like. I’ve never dealt with one before. I’m gonna order one and then put it in and out the generator back together and hopefully it fixes it. I don’t see any way possible it could be anything else.

Take that seal and you might be able to find one at an auto parts store. They can get the same seal with the number on it and may have it in stock. Seals are almost always a general catalog item and are used in all sorts of applications. Transmissions, engine seals, wheel bearings, etc., etc., etc.

ETA: I'm just curious as to why it failed so quickly. Check that bearing for play radially and end play too.

did you check the crank case vent? if it is plugged the pressure will push oil out of the seal.

I don’t know what that is. Let me know and I will check it out tomorrow.

somewhere on that engine is a vent that relieves internal pressure build up. you will have to find it. look for a tube from the valve cover or the crank case that probably terminates into the intake usually in front of the carburetor.

i googled your gen and model. basically just another chinese generator similar to harbor freight. the engine is a champion brand and probably a clone of some sort. but i the search i found a picture of the engine and it appears that the crank case vent is a rubber tube that comes out of the valve cover and goes over to the intake somewhere.

I don’t know what that is. Let me know and I will check it out tomorrow.

Example: Black tube between the valve cover and the intake. You may have to remove the valve cover to see the one-way valve. Be careful not to damage the gasket.

Is it the black tube that is disconnected on this picture? I have one of those on mine. Thanks for the help.

I was gonna get a Harbor Freight Predator until I saw the warranty was only 90 days and I had to buy the battery and the wheel kit myself. That is ridiculous. My champion and my new Duromax have 3 year warranty’s and I added another year on the Duromax. And they came with the battery’s and wheel kits. My Duromax also came with a propane hookup and a bunch of heads for different cables.
