Description
Overview:
The Muffler/Exhaust Gasket for Stihl MS 780 and MS 880 chainsaws (part number 1124 149 0601) is a Genuine Stihl part designed to seal the joint between the cylinder exhaust port and the muffler. Made from heat‐resistant gasket material suited to high temperatures and vibration, it helps prevent exhaust gas leaks that can reduce power, increase noise, and overheat nearby components. A correct seal maintains engine back pressure and efficiency, supporting clean running and reliable starting on heavy‐duty saws. Sized and profiled for an accurate OEM fit on the MS 780 and MS 880, this gasket is a routine service item recommended whenever the muffler is removed or replaced to ensure a secure, leak‐free assembly and long component life.
Key Features:
- Genuine Stihl part for correct fit and performance
- Precise sealing between cylinder and muffler to prevent leaks
- Heat‐resistant construction for continuous high‐temperature use
- Helps maintain proper back pressure, power, and idle stability
- Resists compression set and vibration in demanding cutting work
- Protects mating surfaces from hot gas erosion and soot blow‐by
- Flat profile for easy alignment during refit with standard fixings
- Suitable for routine servicing and post‐repair reassembly
- Direct replacement for the original gasket on compatible models
Typical Applications:
Used during exhaust system maintenance, muffler replacement, decoking, cylinder inspection, or rebuilds on professional Stihl chainsaws. Ideal for forestry, arborist work, sawmills, and heavy felling where long cutting sessions generate high exhaust temperatures. Replace the gasket whenever the muffler is disturbed to maintain a safe, efficient seal and consistent engine performance.
