Description
Overview:
The Bearing Plug 1140 792 2900 is a Genuine Stihl OEM component for selected Stihl petrol chainsaws, including the MS 311 and MS 391. This small, hard‐wearing plug sits in the crankcase area to secure and seal around the bearing location, helping to keep debris out and support correct bearing function. Made from a durable, oil‐ and fuel‐resistant polymer, it is designed for the high vibration and temperature changes typical of chainsaw use. Replacing a worn or missing plug helps maintain smooth rotation, reduces premature bearing wear, and supports consistent cutting performance. It is a straightforward, press‐fit style service part suited to both professional users and DIY maintenance on compatible Stihl models.
Key Features:
- Genuine Stihl OEM part for assured fit and compatibility on listed models
- Durable polymer construction resists fuel, oil, heat, and vibration in daily use
- Helps keep dust and chips away from the bearing area for smoother running
- Supports correct seating and retention of the bearing to reduce wear
- Simple, press‐fit installation with standard workshop tools
- Reliable replacement for cracked, hardened, or missing plugs
- Maintains chainsaw performance and reduces the risk of premature bearing issues
- Suitable for routine servicing as part of preventative maintenance
Typical Applications:
Used during routine servicing, repairs, or rebuilds of compatible Stihl chainsaws to restore the correct sealing and retention at the bearing location. Ideal when addressing rough running, excess vibration linked to bearing areas, or after crankcase cleaning. Suits forestry, landscaping, arborist, farm, and domestic firewood work where dependable operation is essential.
