Stihl Ms 311 Chainsaw Buying Guide
Choosing components for the Stihl MS 311 requires attention to technical matching rather than general power tool criteria. The following criteria form the foundation of our analysis of 15 products and guide practical purchase decisions based on engine architecture, bar length, and operating conditions.
Chain Pitch, Gauge, and Drive Link Compatibility
Chain selection must match the MS 311 factory setup of 0.325-inch or 3/8-inch pitch with .050-inch gauge and exact drive link counts such as 72 links for 20-inch bars. Mismatched pitch reduces cutting efficiency and increases kickback risk, while incorrect drive links prevent proper tensioning on the bar. Products like the Stihl Oilomatic Rapid Super 33RS72E and the Savior 20-inch 3/8-inch pitch 72-drive-link sets provide direct replacements that maintain factory chain speed. When evaluating, calculate required drive links from bar length: for a standard 20-inch bar, 72 links is typical, and multi-pack options improve value for high-volume users who replace chains frequently under hardwood cutting loads.
Aftermarket chains from Savior deliver comparable Oilomatic-style performance at lower cost, but verify the exact part cross-reference such as 3624 005 0072 before purchase. This criterion alone eliminates many generic options that fail to seat correctly on the sprocket.
Cylinder, Piston, and Top-End Rebuild Quality
For engines showing compression loss, a 49 mm big-bore top-end kit or standard 47 mm piston ring pin assembly restores displacement and sealing. The Hyceker MS391/MS311 cylinder piston kit with crank bearings and oil seals addresses 3-bolt intake configurations common to these models and includes components matching 1140-020-1204. AUMEL 47 mm piston ring pin kits offer a more focused replacement for 1140 030 2009 applications. Assess kits by included seals and bearings rather than price alone, as incomplete sets require additional orders and extend downtime. Professional users should prioritize full kits with needle bearings to handle continuous loads without scoring the cylinder wall.
Ignition Coil and Electrical System Reliability
Ignition coils fail under heat and vibration, producing weak spark that prevents starting or causes intermittent cutting. Direct replacements for 1140 400 1303 and 1140 1305 B such as the DEF coil or the Aynaxcol 11404001307 coil-and-filter tune-up kit maintain original timing curves. Bundled kits that also supply air filters reduce the number of service intervals needed. Measure success by whether the part lists exact OEM supersessions rather than broad fitment claims. Electrical components from established brands within Stihl, Stens, DEF and more demonstrate higher resistance to moisture intrusion common in outdoor storage.
Air Filtration and Routine Maintenance Accessories
Dusty environments clog stock filters rapidly and starve the carburetor. The Stens 605-205 air filter designed for MS231 through MS391 series, including the MS311, uses media that matches 1141 120 1600 specifications and allows higher airflow without bypass. Combine filter changes with tensioner adjuster screws such as the ENGINERUN assembly that replaces 1127-007-1003 to keep bar oiling and chain tension consistent. Regular maintenance parts should be stocked in multiples because they are consumable and low cost relative to engine damage from neglected service. Users can explore broader chainsaw category options for complementary tools at the Chainsaws category overview.
Clutch, Sprocket, and Drive System Components
Clutch drum and sprocket kits with needle bearings and E-clips prevent freewheeling losses and ensure power transfer from the 49 cc-class engine. The Adefol 3/8-inch 7-tooth spur clutch drum set for MS391 and MS311 includes five pieces for complete service. Evaluate these by tooth count and bearing presence: missing needle bearings accelerate wear on the crankshaft. Drive system parts directly affect chain velocity, so OEM-equivalent dimensions are non-negotiable for safety and efficiency.
Price-to-Durability Balance Across Options
Components range from entry-level piston kits near $10.99 to complete saws approaching $274.94. Calculate cost per operating hour: a $12.49 piston kit may last one season under heavy use, while a full cylinder kit near $125 provides multi-year service. Full saws such as the Stihl MS 162 serve as capable alternatives when the original MS 311 frame is beyond economical repair. Always cross-check listed part numbers against the saw serial plate rather than relying solely on model name fitment charts.
| Product | Brand | Price | Primary Function |
|---|---|---|---|
| Savior 20 Inch Chainsaw Chain 72 Drive Links | Savior | $35.98 | 20-inch bar replacement chain pack |
| Hyceker MS391 Cylinder Piston Kit 49 mm | Hyceker | $125.99 | Top-end rebuild for MS311/MS391 |
| Stihl MS 162 Chainsaw 16 Inch Bar | Stihl | $274.94 | Complete mid-size saw alternative |
The table above illustrates how price correlates with scope of use across three representative items. Full rebuild kits command higher initial outlay yet restore factory compression, while chain multipacks deliver immediate cutting restoration at lower cost.

Testing & Selection Methodology
We evaluated 15 products by cross-referencing published OEM part numbers against manufacturer documentation for the Stihl MS 311 and closely related MS391 platforms. Selection criteria included exact dimensional match for pitch, gauge, bore diameter, and mounting bolt patterns, followed by brand track record among Stihl, Stens, DEF and more. Price brackets from $10.99 to $274.94 were mapped against included components such as seals, bearings, and multi-packs to determine cost-effectiveness. User satisfaction indicators were limited to available data, so greater weight was assigned to technical compliance and warranty language. Products lacking clear cross-reference numbers were deprioritized regardless of price. This process yields a ranked set focused on functional reliability rather than marketing claims.
Each item was scored on fitment certainty, material specification completeness, and suitability for continuous professional versus occasional homeowner duty cycles. The methodology excludes unsubstantiated performance claims and relies solely on the supplied specifications for chain link counts, piston diameters, and replacement part codes.

Frequently Asked Questions
What chain size fits the Stihl MS 311 chainsaw?
The Stihl MS 311 commonly uses a 20-inch bar with 0.325-inch or 3/8-inch pitch, .050-inch gauge, and 72 drive links. Confirm the exact OEM chain number such as 33RS72E or 33RS3-72 on the existing bar before ordering multi-packs to guarantee proper seating and tension.
How do I know if my MS 311 needs a new ignition coil?
Symptoms include hard starting, weak or no spark after cleaning the plug, and stalling under load. Replace with a coil that lists exact supersessions for 1140 400 1303 or 1140 1305 B. Bundled kits that also include the air filter streamline the service and restore reliable ignition.
Can I use aftermarket piston kits on a professional MS 311?
Yes, provided the kit specifies 47 mm or 49 mm bore and includes matching rings, pin, and seals for the MS311/MS391 series. Full cylinder kits with crank bearings deliver longer service intervals under commercial duty than basic ring sets alone. Always verify the intake bolt pattern matches your engine casting.
What is the typical price range for MS 311 replacement parts?
Individual components and kits for the stihl ms 311 chainsaw fall between $10.99 and $274.94 depending on whether you select a simple piston set, multi-pack chain, or complete top-end rebuild. Complete alternative saws sit at the upper end of that range. Cross-check current listings against the $10.99 – $274.94 to confirm value.
