This authentic OEM exhaust gasket is the seal between the heat deflector and the guard of your chainsaw cylinder, preventing hot exhaust gases from escaping and directing them away from the engine. It is usually found around the exhaust port on the cylinder. However, over time, the gasket can wear out, crack, or become damaged due to exposure to high temperatures and vibrations, leading to exhaust leaks. When this happens, you may notice increased noise or visible smoke around the cylinder area. To replace the exhaust gasket, start by removing the plastic cylinder cover and then take off the muffler by removing its supporting bolts. After that, you can replace the worn-out gasket with the new one. Please note that this replacement part is sold individually and that your chainsaw uses multiple gaskets, so it is crucial to ensure you purchase the correct one for your specific repair needs.

Installed new gasket
Attached muffler & muffler bracket (read that Husqvarna 350 chainsaws have this problem of the muffler falling off, so they created an additional bracket that partly bolts into where the “dogs” are and onto the muffler so it won’t fall off anymore. That’s the theory anyway)
Pretty straight forward repair.
Put new screen on muffler due to carbon buildup. (old saw)
