Husqvarna Chainsaw leaking Bar oil

[Hephaestus29]

I have a Husqvarna 435 Chainsaw.
I only used it one time, I know it’s supposed
to supply oil for the chain but after
storing it in the case, the majority of
the oil leaked out into the case and onto
the floor.

No it wasn’t dropped or damaged in any
way. It was NOT a return item, it was
new, still new actually, just approx. 5
years old. “Just getting to it since I was
In school for 4 years” so it’s been on the
Back burner.

Is this common for this saw?
Has anyone else had this problem?

I noticed there is Not a tank within the
plastic case, the oil is just poured into
the case, I’m not sure if it’s a two
piece case or there’s more parts to the
case. Probably not getting a good seal,
or maybe not sealed at all?

The tank is usually part of the case, gas & bar oil. Most saw I've used and seen will have a small to large amount under them after sitting for a period of time, just the way it is. Quantity of said oil depends on how long it's been sitting. Newer saws may be better about it or have a different oil pump that doesnt seep as much, that likely depends on the saw.

What oils did you use?

Mine weeps a bit with the thin winter oil.

Just Bar oil, I don’t remember the brand.

Was it stored outside with temps going up and down? Usually they all leak some and it seems when they are very clean it's worse. If you are only using it once in 4 years I would be draining both tanks

If you are using it more than that keep a cloth underneath it, don't pack it up until it's cooled down, and before you do open both oil & gas caps to relieve pressure then close back up

I read an article online that said to
fill before use and not after. I guess
I’ll try that before I tear it down all the
way. I just wanted it to be ready for the
next time I used it.

I had a little 14” McCullough, and I never
had this much oil leak from it. That was
the best little chainsaw I will probably
ever see.

I have the same saw, and it does the same thing.

The first thing you should do is clean it off, everywhere you can. Then set it down on a piece of cardboard and leave it overnight. Check the next day to see whereabouts the leak seems to be. Follow from where the oil is on the cardboard back up to narrow down where it's leaking from. If it's on the left side of the saw it may be the cap is either not on tight enough or you may just need a new cap, simple fix. If there isn't any apparent leak it may just have been thermal cycling, it did apparently have four years to work its way out.

I have the same saw...when i put it away hot i crack open the oil fill cap, seems to help some.

They can all leak some oil when stored. Store the saw bar side up or upside down and it wont leak. No need to tear down.

It didn’t take four years, I just haven’t
messed with it in that period of time.
I haven’t needed it, but I’m anticipating
buying a lot to build on, so I’m going to
need it.

I haven't seen one that didn't leak enough to drain the entire tank in less than six months. I take that back. My Shindaiwa never leaked. Wish I'd never sold that one.

From day 1 my Husky 346xp Forrester leaked puddles of oil. IIRC there was a tech bulletin on it. I did a minor file job on the terminal end that mates w/ the bar for a better fit. Still spots a little but acceptable.

 

[Daveyclimber]

A lot of it is due to the oil tank becoming pressurized from temp fluctuations. The looser the tolerance on the pump, the worse it will leak. Drain tank prior to storage, that goes for fuel as well.
