Husky 335 XPT; 3D puzzle [ Chainoil problem ? ]

[Jan-Sietze]

I have my 335 rebuild because the pump piston eats the sprocket...
This is probably due to aging of the biological chain oil, which then very thick and sticky.

(Most parts have been cleaned and are drying here)


Which chainoil is suitable for chainsaws which are not used much?
Maybe WD-40 or hydrolic oil?

But I still doubt about the chain oil to use ...
I do not want that again the pump sticking by obsolete oil
(and empty after every use is not an option...)

I believe bar oil is essentially 30W, plus 'sticky stuff.'

 

[KenJax Tree]

I believe bar and chain oil is your best bet. Bar oil isn't gonna hurt anything, how long is the saw sitting for in between uses?

This plastic worm wheel is ruined when the oil pump is stuck.
This is now the second gear which has been broken ...

I now have renewed the pump itself to avoid the problem.
And of course a new worm wheel is placed...

well, stop running vegetable oil, and run some good petroleum bar oil.

Anything EPA approved isn't good for anything

Well, to be fair, he is in Euope, and it might be a requirement where he is cutting to run biodegradeable oil. They have many more centuries of intense human use of environment on large scales to look at to develop their policies.

I am not totally against the EPA, just some of their more extreme policies that rest on shaky science, or play fatcat billionare favorites such as highly restricted two strokes while almost completely ignoring oceans of bunker fuel to be burnt. One cargo ship delivery must dwarf all the chainsaw pollutants. I can't prove that, butttttttt..its gonna be close....but, billionaires profits runthis, nation, that's, so I will just leave it that.

Gave my suggestion to the OP, don't want to sidetrack the thread. EPA has nothing to do with his problem. unsubscribing

I would like to use petroleum based bar oil, but it is simply not sold here in the Netherlands...

I am having chain oil issues with my 339 too, i just put in the oil pumps new parts and the damn thing would not pump a s-it...well....year ago actually, and i gotfed up with the saw, but as this is thread of a similar saw, ill be lurking this too.
