husky 372

[coxy]

why does this thing keep blowing the muffler apart the saw is little over a year old and put 4 of them on it at 90 bucks a pop the jonnyreds don't have this prob at least my any way ;D         thanks for any info

Dealer don't know? Call up Husky direct. Must be a reason why.I have an older 372,6-8 years old.

dealer told me I was tacking the drags down to far  and it was vibrating to much never heard that one before   but it doesn't bother my jonnyreds  and they are the new 2172s

[treeslayer2003]

put blue Loctite on the screws.

tacking the drags down to far? Meaning using the dogs to cut with?

[husky fan 500]

ur dealer said that u had the rakers filed down too far???  that would give a little more vibration as u know. is the muffler coming apart or coming loose?  if its loose use loctite if it comes apart id put a couple of tack welds on the seam between the halves

[thecfarm]

rakers,  :-[  Never heard them called drags. I guess I need to get off the hill more.

Maybe you do, as it isn't that uncommon to call them drags... ;)

I dunno who will agree on this and who not, but here it is. If you got them screws coming loose on J-Red or a Husky, and nothing else works, refit it with left hand threads.

[sharkey]

I think your going to find whether left or right thread its the vibration that is causing the problems.  Red Loctite or buy longer bolts and safety wire it.  Bailey's has the aftermarket muffler on sale for $30.

the bolts are not coming lose the muffler is splitting in half but not at the seem  or it blows a hole in the side by the bar  ???

[JohnG28]

That sounds like an interesting problem!  ???

[sweetjetskier]

I have 2.5 years of run time on a 372 x-torq and have not had any problems at all with the saw.

I always check fasteners when I clean up the saws after use though

"Holy hoppers Batman !!!!"  Never head of that happening before. Any chance of posting a pic?
Man thats tough to wrap my brain around the exhaust pressures needed for that to happen coming from a small 2 stroke of any sort. Bad welds would have been my first thought but blasting out the side is wild.

Coxy,what are you feeding that critter.??I would just weld a heavier patch inside the muffler where the burnthroughs occure.I think there are outher problems afoot here perhaps burning too hot or lean. Frank C.

sorry meant to say and blowing a hole after it splits  sorry

[coxy]

I run the same gas in the other saws and it doesn't bother them  was told it might be a bent crank ??? don't under stand how that could happen  but weird things happen to strange people :D going to try one more muffler if it cracks its dozer bait ;D

[tlandrum]

when you give up on it let me know and I can figure it out for you. I have all the needed parts to fix anything it could be.

[husky fan 500]

no no no dont make it dozer bait. there are aftermarket dual port mufflers out there that might be an option 4 u  or if ur anything like me take one of the old ones and make your own.  i just made one last wknd  i drilled a hole in the side  one half the dia of the oem hole there is a difference but not a great lot
