Description
Overview:
This Cylinder Gasket is a genuine Stihl part designed for the joint between the cylinder and crankcase on two-stroke engines. Built from heat-, fuel- and oil-resistant composite gasket material, it provides a precise seal to maintain engine compression and crankcase vacuum, preventing power-robbing air leaks. It is manufactured to OEM specification for an accurate fit on the Stihl MS 461 chainsaw and GS 461 cut-off saw, helping to deliver reliable starting, stable idle, and full power under load. A sound cylinder base seal reduces the risk of lean running and premature wear, supporting long service life in demanding use. Supplied as a single gasket, it is suitable for professional workshops and DIY users carrying out top-end servicing or repairs on compatible Stihl machines.
Key Features:
- Genuine Stihl OEM component for assured compatibility and fitment (MPN: 1128 029 2310)
- Precision die-cut for correct port alignment and consistent sealing surface
- Durable composite fibre construction, resistant to petrol, oil, and operating temperatures
- Maintains cylinder compression and crankcase sealing to preserve performance
- Helps prevent air leaks that can cause hard starting, high idle, or lean running
- Supports smoother acceleration and dependable power delivery under load
- Stable thickness to maintain correct assembly stack and clearances
- Suitable for regular professional use and routine workshop rebuilds
- Straightforward to install during a top-end service with standard tools
- Supplied as a single gasket for one machine
Typical Applications:
Used during top-end rebuilds, cylinder or piston replacement, and when diagnosing air leaks or loss of compression on Stihl MS 461 or GS 461 engines. Ideal after seizure repairs, decarbonising, or whenever the cylinder is removed. Helps restore reliable starting, steady idle, and full cutting performance for forestry, arborist, and concrete-cutting tasks.
