Description
Overview:
The baffle for Stihl MS 201 chainsaws (MPN 1145 120 4105) is a shaped airflow guide that sits within the cooling system to channel air around the cylinder and exhaust area. Made from a tough, heat-resistant polymer, it helps maintain steady engine temperatures, reducing hot spots and supporting smooth running. This direct-replacement part is engineered to match the original geometry so it fits cleanly without modification and works with existing fixings. It is suited to Stihl MS 201 and MS201C professional and homeowner machines used for pruning, logging, and general arborist and landscaping tasks. Replacing a damaged or missing baffle restores proper cooling performance and helps protect the engine during sustained cutting.
Key Features:
- Purpose-built airflow control to aid engine cooling and efficiency
- Heat-resistant, impact-tough polymer construction for long service life
- Direct replacement for the original baffle; uses existing mounting points
- Helps prevent overheating during prolonged or heavy cutting
- OEM-matching shape for correct clearance with starter cover and flywheel
- Resistant to fuel mist, oil, debris, and vibration common in chainsaw use
- Lightweight part that maintains tool balance and handling
- Clear reference to OEM number 1145 120 4105 for easy identification
Typical Applications:
Routine maintenance or repair when the original baffle is cracked, missing, or heat-damaged. Suitable for restoring correct cooling airflow on MS 201-series saws used for arborist climbing work, ground cutting, firewood processing, and site clearing, helping keep engine temperature stable during day-to-day use.
