Having a problem here, and I have no solution as of yet. I was cutting yesterday with my Husky 350 and one of the muffler bolts backed out and I lost it. They have backed out a couple of times before but I have caught them before they fell out. Well, now I am without a saw until I locate a bolt. Also, the muffler gasket tore somehow and is gone as well. So if anyone has any ideas on where I can order these parts, please let me know. I want to go ahead and order a few bolts so I have extras, and a couple of gaskets too. I tried Jeff Sikkema first, but he doesnt have anything either and he is not a Husky dealer. I have the part numbers as well.. the muffler bolt is - 5032029-87.
The gasket is 5038625-01. Thanks!!
 
There has to be somewhere where a guy can order Husqvarna saw parts. Where do you all get your husky parts when they break? Thanks!
 
Oh yeah and once I do get the muffler bolts, how can I keep them from falling out again? I was thinking some locktite and a lockwasher. Anyone else ever have muffler bolts rattle their way out?
 
My Huskies never break unless I do something stupid.

Did you try CCD? Let me know if they couldn`t help you.

Loctite should work but don`t use the permanent or high strength type.

The small husky saws have a self locking nut for the exhaust. If your saw did not have them it was probably a mistake. If you look real close at the type I am talking about they are not quite round looking where the threads are located. This keeps them on real well and is why others have not had this problem. Mike
 
Husqvarna has made a change in the muffler to better maintain the tighting torque of the muflfer bolts. If you will send me your email address I will send you a copy of the bulletin. If the saw is still in warranty or even if it's not you might go to your dealer and raise enough stink about it you might get a new muffler, bolts and gasket.
 
Typhoon, You can probably find a suitable bolt at your local harware store (if they carry metric). Use the proper lockwasher and it won't back out. If it is a nut that you need, you could make a locking nut using a center punch. Set the nut on end on anvil or vise then place the punch on one of the flats and tap the punch with a hammer. This will dimple the nut. The nut will be slighter harder to thread on but it won't rattle loose either. If it's a small nut be careful. Too much pounding and the nut will be egg shaped and ruined. Or you coul.d just use a lockwasher. As for the gasket, if you can't find one, you can obtain a roll of gasket material at your local auto parts store and make your own gasket.
All you would need are scissors, a round hole punch, maybe a boxcutter and a pen. use the old gasket or exhaust flange as a template. The actual parts may be better but if your in a pinch and need the saw now, you can make it happen. Hope this helps and good luck. Lucky
 
Hi Tyfoon, as a general mantainance procedure, like when cleaning, sharpening or fueling up, keep a t-handle nearby and check the bolts for tightness, this includes the handle bolts and all the other ones. Test the muffler bolts often when the saw is hot, they will usually be a "snapping sound", loose. The worst thing to do is reef on them, this causes further problems. It doesn't take long to occasionaly check them for tightness.
The muffler bolts are always suspect due to all the expansion, contraction and vibration.
It is better, I think to get into the habit of checking them daily as opposed to using locktite.

Get rid of the gasket

Who would worry about a little exaust gas escaping?
I did it on my 372, following the advice of someone from this site. By having metal to metal contact, more efficient heat transfer to the muffler can occur. And if your muffler is unrestricted (as it should be) this will allow for greater cylinder heat dissipation. You buy that?

Gypo, I do just that exactly, every day. Every couple times I fuel, I check all of the bolts. And, funny thing is, I had just checked them before they fell out, and sure enough one of them was a little loose. So I cranked them down pretty tight. Half of a tank of fuel later, one fell out. I don't understand it. I am going to try locktite and a lockwasher on each next time to see if that helps. Thanks!
 
I had the same problem with my old Husky 181. Went to the local saw shop and he wanted to sell me a couple of special "case hardened muffler bolts". He wanted quite a bit for em' so I did what Lucky did and got some grade 8 metric bolts from the hardware store. They worked like a charm and I could have bought a whole bagful for what the Husy ones cost. Now if I could just figure out how to keep the bar adjuster bolt from coming loose.
