Leaking gas caps

[Max]

Does anyone else have issues with Husky gas caps leaking.
My 340 and 357 are fine for days then all of a sudden they leak/weep.

They are kept in my cool dry basement. I ordered and installed new Husky OEM "o" rings, they still leak. One fix was taking a spare cap from an E-Tech
141 green cap and putting on the 340. This stopped the leak on that one.
I am temped to order another green cap for the 357. The caps do differ in size. I am still relatively new to the Husky saws, does this happen often to these?

Thanks.

I am not at work right now but I think the vented cap will fit and solve the problem. I think the P/N is 503 8280-01 going from memory.

Thank you!
I will look into that.

Thank you!
I will look into that.

I was just down at work for a second. The P/N is 503 8280-04. I have used this on 365's ,372's and 385's. You will have to put a small chamfer on the leading edge with a dremel tool or something similar. 2 minutes work.

Also sometime this year husqvarna switched to new oil and fuel caps.
My new 353 have them. Really nice, much easier to open and I think the seal are more reliable too. It's no o-ring seal now, somewhat more complex.
But maybe you already know this.

I did not know that, thanks.
I will stop by the dealer and see if I can pick up a new style gas cap.

Took some pictures of the nice new caps.
4 first ones are the gas cap. Last one is the oil cap. This still use the flat seal as shown in the picture in the next post...

 

[SawBrian]

...flat seal here, though leakage should be minimum here with proper viscocity bar oil. I'll never had leakage with these caps, as I have seen. But with the old caps and seals on a 339 I have often. Specially If the sun or warm weather makes great pressure in the tank the seals just wont hold it.

Husky always improving

Thank you.

A picture is worth a thousand words.
Now I know what to look for tomorrow.
Thanks again SawBrian!

Both of my 372's leak. Dont overtighten them, it makes it worse.

 

[Max]

Nice to see you again Ben.

I have never over tightened them. I always go light when tightening.
I learned the hard way on an older 029 not to over tighten, especially in
30 degree weather! What a disaster that was!

 

[bwalker]

Thank you.
I have found that if you have a leaky cap getting a new one and paying attention to not over torqueing it solves the problem.

You could also go to your local NAPA store and get an o-ring to fit. Might solve your problem.

Thanks SawBrian

I went to the dealer and he agreed with me about the leaking cap.
He gave me a new one that is the same style you pictured.
The new cap is on, no leaks...back in business!
