ECHO CS-310 CS-352 ES SHINDAIWA 340S Chainsaw Exhaust Muffler Bolt Nut Set

Exhaust muffler bolt and nut set fits Echo CS-352, CS-353 (ES) and Shindaiwa 340S chainsaws. These bolts and nuts secure the exhaust muffler to the engine block, holding it firmly against its mounting gasket to keep the joint sealed. When the fasteners corrode, strip, or work loose, the muffler can sit unevenly or vibrate against the engine, breaking the seal at the mounting joint and allowing exhaust to leak or the muffler to rattle loose during use. Fitting a replacement bolt and nut set restores a secure, properly torqued mounting for the muffler.
