    Default 031av muffler repair, use JBWeld??

    The side flange (support piece) on my 031av muffler has come loose... Do you think JB weld would/could be used to repair it?

    I took a quick look at ebay a new muffler was $70, used ones were $20ish, but most seemed to have 'issues' .. I am heading to a dealer to see their cost, but for no more than it gets used I cant see putting $70 in a almost 40 yr old saw..

    If not JB Weld, any other suggestions?

    I doubt that JB would take the heat. May have to silver solder it.

    Is it unusable as it is? Other than being louder, is there a problem?

    The muffler will get hot enough to burn the JB Weld and you will have a real mess. I had an 031 AV up until 2 years ago. It was a good reliable saw but it vibrated much more than the newer saws due. The 031's still seem to be a hot seller on ebay in the $150 range.
    There is a good used muffler on ebay right now for your saw for $19.99 buy it now.
    The auction item # is: 140530606039

    It appears to be usable as is.. not sure if the gasses coming out of the side of the muffler toward the bar would be ideal though..

    Looking online i found some Permatex puddys and such for exhaust repairs.. Anyone try those?

    Could you post a pic of damage.

    I had a 031 with the module going out it. Run 30mins heat up, break up, shut down. Wait to cool to do it again. The part that was going bad was NLA.

    I noticed back then the 031 had 2 different muffler types.

    Sorry. Bronze = Braze ("solder") using acetylene touch with bronze filler rod. Would definitely be DIY assuming you had a torch... Good excuse to go buy one

    the muffler on the saw has a different looking exhaust hole than the ones I see on ebay.. This saw does NOT have a chain brake, so it is an earlier model than most you see..

    My neighbor is a certified welder and he thought he could fix it for me, so i just dropped it off at his house this morning.. It was a stress crack/fracture - when i took it apart one of the header bolts was missing and the other was loose - so i think the shaking cracked the piece..

    I can't find a pic of it except on ebay.. But the flange that broke has a bolt that goes thru/near that chain oiler into the muffler..


    The muffler is no longer available (no surprise there) - BUT the dealer list price would be $170 if they had one in stock... $70 for new or $30 for used on ebay sounds better and better if the welding doesnt help..
