Description
Overview:
This Cylinder Gasket is a genuine Stihl OEM part designed for the MS880 and MS780 professional chainsaws. It is a precision-cut cylinder base gasket that sits between the cylinder and the crankcase. Made from heat‐resistant, fuel‐ and oil‐compatible gasket material, it forms a tight, reliable seal to maintain correct compression and crankcase vacuum, preventing air leaks and fluid seepage. A secure base gasket supports easy starting, stable idling and strong cutting performance under heavy load. Suitable for routine servicing and full top‐end rebuilds, it helps protect the engine by keeping unmetered air, dust and contaminants out of the combustion area. Being an exact OEM match, it aligns with the original port shapes and bolt pattern for consistent fit and long-term sealing integrity.
Key Features:
- Genuine Stihl OEM part for assured compatibility and quality
- Provides a proper cylinder-to-crankcase seal to maintain compression and vacuum
- Durable, heat‐resistant material compatible with petrol, two‐stroke oil and exhaust temperatures
- Precision-cut profile for accurate alignment with ports, studs and dowels
- Helps prevent air leaks that can cause poor running, overheating or seizure
- Consistent thickness to support correct assembly and reliable engine performance
- Suitable for demanding professional and DIY use in forestry, arborist and construction environments
- Straightforward fitment using standard hand tools during top-end service or rebuild
- Supports smoother starting, cleaner idle and sustained power under load
- Genuine Part status reduces the risk of premature failure compared with unverified alternatives
Typical Applications:
Used when refitting or replacing the cylinder during piston changes, decoking, deglazing, or full top‐end rebuilds. Ideal when diagnosing vacuum leaks, restoring lost compression, or after damage to the original gasket. Suitable for preventative maintenance to keep MS780/MS880 engines running reliably in forestry, milling, felling, and heavy site work.
