Title: Jonsered 2094
Post by: wild262 on April 16, 2015, 11:23:36 am
I'm working on a 2094 for a guy who logs, and he said the bar oil gets into the fuel and vise versa. One these models the oil and tank reservoir are side by side.  A dumb design in my opinion.  When I drained the fluids, there was mix in the bar oil tank, so he must be right.  There  is a pin hole leak from the outside of the case near the mix cap on the bottom side.  I suspect its been on the concrete too long.  If he hadn't just spent $ on a new jug & piston, I would have told him to part it out and get something else.  He's not made of money and wants to keep cost down which I certainly understand.  Saw runs out good except for these issues.  He's using a 2095 now for a spare till I get this one done.  What would you guys do here, any thoughts?  What about using a tanks sealer or coating like for motorcycles?  Anyone with any experience with this stuff?  Thanks in advance. :)

Maybe you can seal the tank as if it were a rusted steel one?

Yes maybe.  If I have to resort to using the sealer, I will do both sides even though the oil side looks good inside.  The mix side has some corrosion around where the case gasket is.  Likely where its leaking.  To fix it right way would involve a complete tear down and splitting the cases.  Way to much work & cost for what it is.  I told him to keep them metal cased saws off that concrete floor.  he agreed.  One thing is for sure, parts are not easy to find for these saws.  They seem run good, but **** poor design, I think. ::)

Good to seal both tanks

UP-date on the tank sealer.   Very impressed the way this stuff is working. ;D  Applied it to both sides, and let cure a solid week.  Filled tanks, and done some cutting.  So far after 2 tanks, NO mixing of the two.  This stuff does work, at least for now.  Only time will tell with vibration and all.  As for now, I'm calling this job done.  ;)  Good day to all.
