Choosing the right chain for your 026 is crucial, and it’s not just about matching the pitch and gauge. It’s about understanding the wood you’re cutting, the type of work you’re doing, and how different chain designs can impact your speed, efficiency, and even safety. In this guide, I’ll share my experiences and insights – gathered over years of felling trees, bucking logs, and turning wood into warmth – to help you make informed decisions about your chain and bar upgrades. I’ll also offer 5 expert tips to elevate your chainsaw game.
Stihl 026 Chainsaw Chain Choices: Best Bar Upgrades (5 Expert Tips)
The Stihl 026 is a legend. It’s a workhorse that’s earned its stripes in forests and woodlots worldwide. But even the best chainsaw is only as good as its chain and bar. Understanding your options and how they affect performance is key to maximizing the 026’s potential. I’ve seen firsthand how the right setup can transform this saw from a reliable tool to an absolute beast in the woods.
Understanding Chain Pitch, Gauge, and Drive Links
Before diving into specific chains, let’s nail down the basics. These are the three musketeers of chainsaw chain specs: pitch, gauge, and drive link count. Getting these wrong is a recipe for disaster.
- Pitch: This is the distance between any three consecutive rivets on the chain, divided by two. It’s usually expressed in inches (e.g., .325″, 3/8″). The Stihl 026 typically uses a .325″ pitch chain, but some older models might use a 3/8″ low profile (3/8″ LP) chain.
- Gauge: This is the thickness of the drive links, which fit into the groove of the guide bar. Common gauges are .050″ (1.3mm) and .058″ (1.5mm). The Stihl 026 usually uses a .050″ gauge.
- Drive Links: This is the number of drive links on the chain. It’s determined by the length of your guide bar and the pitch of the chain. You’ll need to count the number of drive links on your old chain or consult your saw’s manual to find the correct number.
Why is this so important? Because using the wrong pitch, gauge, or drive link count will prevent the chain from fitting properly on the bar and sprocket, potentially causing damage to your saw, bar, and chain. It can also be a serious safety hazard. I once saw a guy try to force a chain with the wrong pitch onto a bar. The chain snapped within seconds of starting the saw, sending metal flying. Luckily, no one was hurt, but it was a close call.
Common Chain Types for the Stihl 026
Now that we’ve covered the basics, let’s look at some common chain types that work well with the Stihl 026. These chains differ in their cutting performance, maintenance requirements, and suitability for different types of wood.
- Full Chisel: These chains have square-cornered cutters that offer the fastest cutting speed. They’re ideal for clean wood and experienced users. However, they dull quickly when exposed to dirt or abrasive materials.
- Semi-Chisel: These chains have rounded-corner cutters that are more forgiving than full chisel chains. They’re a good all-around choice for both clean and slightly dirty wood. They also stay sharp longer than full chisel chains.
- Low Profile (Micro-Lite): These chains have a smaller cutter design that requires less power to operate. They’re a good choice for smaller saws and users who prioritize ease of use over cutting speed. They’re also less prone to kickback.
- Ripping Chain: These chains are designed for cutting wood along the grain (ripping). They have a different cutter angle than cross-cutting chains, which allows them to cut more efficiently along the wood fibers.
My Experience: I’ve used all of these chain types on my Stihl 026. For felling clean hardwood like oak or maple, I prefer a full chisel chain for its speed. But for cutting firewood, where I often encounter dirty wood, I opt for a semi-chisel chain. And for milling lumber, a ripping chain is a must.
Stihl Chain Nomenclature Explained
Stihl uses a specific naming convention for their chains. Understanding this nomenclature can help you identify the right chain for your needs.
-
Example: Stihl 26RS3 74
- 26: This indicates the chain’s drive link thickness in thousandths of an inch. Most Stihl chains use a 0.050″ (1.3mm) gauge drive link, which corresponds to the “26” designation.
- RS: This indicates the chain type. “RS” stands for Rapid Super, which is Stihl’s designation for a full chisel chain. Other common designations include “RM” (Rapid Micro, semi-chisel) and “PM” (Pico Micro, low profile).
- 3: This indicates the chain pitch. “3” corresponds to a .325″ pitch chain.
- 74: This indicates the number of drive links.
Pro Tip: Stihl also uses color coding on their chains to indicate the chain type. Full chisel chains typically have yellow cutters, semi-chisel chains have green cutters, and low profile chains have black cutters.
Best Stihl Chain Options for the 026
Based on my experience and research, here are some of the best Stihl chain options for the 026, depending on your needs:
- For General Purpose Cutting (Firewood, Felling Small Trees): Stihl 26RM3 (Rapid Micro, .325″ pitch, .050″ gauge). This is a great all-around chain that’s durable and easy to maintain.
- For Fast Cutting in Clean Wood (Felling Large Trees, Bucking Logs): Stihl 26RS3 (Rapid Super, .325″ pitch, .050″ gauge). This chain offers the fastest cutting speed, but it requires more frequent sharpening.
- For Cutting Hardwood (Oak, Maple): Stihl 26RS3 (Rapid Super, .325″ pitch, .050″ gauge). The aggressive cutting action of the full chisel chain is ideal for hardwoods.
- For Cutting Softwood (Pine, Fir): Stihl 26RM3 (Rapid Micro, .325″ pitch, .050″ gauge). The semi-chisel chain is less prone to clogging when cutting resinous softwoods.
- For Plunge Cutting and Limbing: Stihl 23RS3 (Rapid Super, .325″ pitch, .050″ gauge). This chain has a slightly smaller cutter design that makes it easier to control during plunge cuts.
Case Study: I once used a Stihl 026 with a 26RS3 chain to fell a large oak tree that was threatening a client’s house. The chain cut through the 24-inch diameter trunk with ease, allowing me to bring the tree down safely and efficiently.
Guide Bar Selection and Upgrades
The guide bar is just as important as the chain. It supports the chain and guides it through the cut. Choosing the right bar length and type can significantly impact your saw’s performance and safety.
- Bar Length: The Stihl 026 can accommodate bar lengths ranging from 16″ to 20″. A shorter bar is easier to control and maneuver, while a longer bar allows you to cut larger diameter trees.
- Bar Type: There are two main types of guide bars: laminated and solid. Laminated bars are made from multiple layers of steel that are bonded together. They’re lighter and less expensive than solid bars, but they’re also less durable. Solid bars are made from a single piece of steel. They’re more durable and resistant to bending, but they’re also heavier and more expensive.
My Recommendation: For most users, a 16″ or 18″ laminated bar is a good choice for the Stihl 026. It provides a good balance of maneuverability and cutting capacity. However, if you’re frequently cutting large diameter trees or working in harsh conditions, a solid bar might be a better investment.
5 Expert Tips for Stihl 026 Chain and Bar Upgrades
Here are 5 expert tips to help you get the most out of your Stihl 026 chain and bar:
- Sharpen Your Chain Regularly: A sharp chain is a safe chain. A dull chain requires more force to cut, which can increase the risk of kickback. I recommend sharpening your chain every time you refuel your saw or after every few hours of use, depending on the wood you’re cutting. Use a high-quality chainsaw file and follow the manufacturer’s instructions carefully. The correct filing angle is crucial. I use a Stihl 2-in-1 filing tool. It makes the sharpening process so much faster and easier, and ensures that I maintain the correct depth gauge setting.
- Maintain Proper Chain Tension: Proper chain tension is essential for safe and efficient cutting. A chain that’s too loose can derail from the bar, while a chain that’s too tight can overheat and damage the bar and chain. Check the chain tension before each use and adjust it as needed. The chain should be snug against the bar but still able to be pulled around the bar by hand. I use a screwdriver to adjust the tensioning screw on my Stihl 026.
- Lubricate Your Chain and Bar: Proper lubrication is crucial for extending the life of your chain and bar. Use a high-quality chainsaw bar and chain oil. Check the oil level frequently and refill it as needed. I prefer using a biodegradable bar and chain oil to minimize my environmental impact.
- Clean Your Bar Regularly: Debris can accumulate in the bar groove, which can interfere with the chain’s performance. Clean the bar groove regularly with a screwdriver or bar groove cleaner. I also use compressed air to blow out any remaining debris.
- Consider a Sprocket Upgrade: The sprocket is the part that drives the chain around the bar. Over time, the sprocket can wear down, which can reduce the chain’s cutting efficiency. Consider replacing the sprocket when you replace your chain or bar.
Wood Selection Criteria and Technical Requirements
Choosing the right wood is crucial for various applications, from firewood to construction. Here’s a breakdown of essential criteria and technical requirements:
