Hey all

 

Firstly apologies resurrecting an post of old.

 

I currently have my mates husky 345 on the bench with the exact same fault - oil leaking around the through bolt mounted within the oil tank.

 

I have managed to re site the bolt into the hole but its still leaking. Is there any easy fix issue (unlikely) OR what is the best fix for this problem??

 

Any knowledge would be gratefully received.

 

The offending bolt around which the oil is leaking is 503 87 54-01 (x2) in this diagram - however they mount through a channel which looks like aluminium??

not driven the bar studs out but would reckon they should be knocked through to the oil tank and the holes and inner tank should be degreased than the bolts put back in with a bit of epoxy around them to seal them in - put the bar back on with the epoxy still soft and do it up to avoid them shifting later.

 

Thats my suggestion without doing the job before - more used to screw in ones.

Yes to be honest I have only ever seen screw in / out bolts before and I only realised how these were mounted when one decided to push in to the oil tank whilst putting the bar back on!!

 

I thought about the glue in / epoxy route as I couldn't see any way to get the bolt to seat and seal itself ? The other bolt seems to be just pushed through and that seals it since there is no leak on that one which seems to suggest user error when mounting the bar over the years, or impact upon the bolt.

 

I think i'll give the epoxy route a go and see if we can sort it without a full rebuild, no other issues on the saw other than this annoying one.

 

Thanks again spud

could you not put a small o ring on the stud before refitting through the oil tank,as when the bar is tightened should seal around the stud hole on inside

[kentjames]

Could do, however the o ring wouldn't stop it pushing back into the tank again when tending to the chain / bar etc. Think the glue is probably the best option with the original parts, not sure how much clearance / play there was on the bolt originally but it seems odd it just pushes out / in !
