Stihl Chainsaw 28 Inch Bar: Matching Drive Links Explained (Pro Tips)

Ever notice how a finely tuned chainsaw just sings through wood? It’s not just about raw power; it’s about the perfect harmony of bar length, chain type, and, crucially, the right number of drive links. Mess that up, and you’ve got a chainsaw that’s more frustrating than functional. Today, we’re diving deep into the world of Stihl chainsaws, specifically those sporting a 28-inch bar, and unraveling the mystery of matching drive links. Get ready for some pro tips that’ll keep your saw humming and your projects on track.

The Heart of the Matter: Why Drive Links Count

I remember a time, green as could be, when I thought all chainsaw chains were created equal. I grabbed a chain off the shelf, slapped it on my saw, and promptly spent the next hour wrestling with a floppy, ill-fitting mess. That’s when I learned the hard way that drive links are the unsung heroes of chainsaw performance.

What are Drive Links?

Drive links are the small, tooth-like projections on the chainsaw chain that fit into the guide bar groove. They’re the engine’s direct connection to the wood, pulling the chain around the bar at high speed. The number of drive links directly corresponds to the length of the guide bar and the sprocket size.

The Consequences of Mismatching

Using a chain with the wrong number of drive links can lead to a whole host of problems:

• Chain Slippage: Too few drive links, and the chain will be too loose, prone to slipping off the bar.
• Binding: Too many drive links, and the chain will be too tight, causing excessive wear on the bar, sprocket, and even the chainsaw engine.
• Poor Cutting Performance: An improperly fitted chain won’t cut efficiently, leading to increased fuel consumption and frustration.
• Safety Hazards: A loose or binding chain is a serious safety risk. It can snap, derail, or cause the saw to kickback unexpectedly.

Stihl Chainsaw 28-Inch Bar: Finding the Magic Number

So, how many drive links do you need for a Stihl chainsaw with a 28-inch bar? The answer isn’t always straightforward, as it can depend on the specific Stihl model and chain type. However, I can give you some guidelines.

General Rule of Thumb

For most Stihl chainsaws with a 28-inch bar, you’ll typically need a chain with 91 drive links. However, always verify this information with your chainsaw’s user manual or the Stihl website. Different Stihl models, even with the same bar length, might require slightly different drive link counts.

Why Check Your Manual?

Manufacturers often make subtle changes to bar and sprocket configurations over time. Relying on outdated information or generic assumptions can lead to costly mistakes. Your chainsaw’s manual is the definitive source for the correct drive link count.

Identifying Your Stihl Model

Before you can consult the manual or online resources, you need to know your Stihl chainsaw model number. This is usually found on a sticker or plate located on the engine housing. Common locations include:

• Near the handle
• On the side of the engine
• Underneath the chainsaw

Once you have the model number, you can easily find the correct drive link count in the manual or on the Stihl website.

Chain Pitch and Gauge: The Other Critical Factors

Drive links are only part of the equation. You also need to consider chain pitch and gauge to ensure proper fit and performance.

Understanding Chain Pitch

Chain pitch refers to the distance between any three consecutive rivets on the chain, divided by two. It’s usually measured in inches. Common chainsaw chain pitches include:

• .325 inch: A popular choice for mid-sized chainsaws used for general cutting tasks.
• .375 inch (3/8 inch): A common pitch for larger chainsaws used for felling trees and bucking logs.
• .404 inch: Typically found on heavy-duty chainsaws used for professional logging.

Understanding Chain Gauge

Chain gauge refers to the thickness of the drive links where they fit into the guide bar groove. It’s also measured in inches or millimeters. Common chainsaw chain gauges include:

• .043 inch (1.1 mm): Used on some smaller chainsaws.
• .050 inch (1.3 mm): A very common gauge for a wide range of chainsaws.
• .058 inch (1.5 mm): Often found on larger, more powerful chainsaws.
• .063 inch (1.6 mm): Typically used on heavy-duty chainsaws.

Matching Pitch and Gauge to Your Saw

Using the wrong pitch or gauge can be just as problematic as using the wrong number of drive links. The chain might not fit properly on the sprocket, or it might bind in the guide bar groove. Again, consult your chainsaw’s manual for the correct pitch and gauge specifications.

A Personal Anecdote: The Gauge Gaffe

I once tried to use a chain with the wrong gauge on my Stihl MS 261. The chain fit loosely in the bar groove, and the saw vibrated excessively. It was a miserable experience, and I quickly realized my mistake. I swapped the chain for one with the correct gauge, and the saw ran smoothly and efficiently. Lesson learned: always double-check the pitch and gauge!

Pro Tips for Choosing the Right Chain

Now that you understand the importance of drive links, pitch, and gauge, let’s dive into some pro tips for choosing the right chain for your Stihl chainsaw with a 28-inch bar.

1. Consider Your Cutting Needs

What type of wood are you cutting? Are you felling trees, bucking logs, or pruning branches? The type of cutting you’re doing will influence the type of chain you need.

• For Softwoods: A chain with a more aggressive cutter design will help you cut through softwoods quickly and efficiently.
• For Hardwoods: A chain with a more durable cutter design will withstand the wear and tear of cutting hardwoods.
• For Dirty Wood: A chain with a hardened cutter design will resist dulling when cutting dirty or abrasive wood.

2. Choose the Right Chain Type

Stihl offers a variety of chain types, each designed for specific applications. Some popular options include:

• Rapid Micro (RM): A low-vibration chain that’s ideal for general cutting tasks.
• Rapid Super (RS): A high-performance chain that’s designed for fast cutting speeds.
• Rapid Duro (RD): A carbide-tipped chain that’s extremely durable and resistant to dulling.

3. Don’t Skimp on Quality

Chainsaw chains are not created equal. Cheaper chains may seem like a bargain, but they often dull quickly and break easily. Investing in a high-quality chain from a reputable manufacturer like Stihl will save you time, money, and frustration in the long run.

4. Keep Your Chains Sharp

A sharp chain is essential for safe and efficient cutting. Dull chains require more force to cut, which can lead to kickback and other hazards. Learn how to sharpen your chainsaw chain properly, or take it to a professional for sharpening.

5. Maintain Your Chain Properly

Proper chain maintenance will extend the life of your chain and improve its performance. Keep your chain clean and lubricated, and inspect it regularly for damage. Replace your chain when it becomes worn or damaged.

6. Bar and Chain Oiling

Proper lubrication is critical for chainsaw performance and longevity. Use a high-quality bar and chain oil that’s designed for your chainsaw. Check the oil level frequently and refill as needed.

Types of Bar and Chain Oil

• Mineral-based: Traditional option, effective but not biodegradable.
• Vegetable-based: Eco-friendly, biodegradable, and provides excellent lubrication.
• Synthetic: Offers superior performance in extreme temperatures and reduces wear.

Oiling Best Practices

• Check oil level: Before each use, ensure the oil reservoir is full.
• Adjust oiler: Adjust the oiler flow based on wood type and cutting conditions. More oil is needed for hardwoods and longer cuts.
• Clean oil ports: Periodically clean the oil ports on the bar to ensure proper oil flow.

7. Chain Tension

Proper chain tension is crucial for safe and efficient cutting. A chain that’s too loose can derail or cause excessive vibration. A chain that’s too tight can bind and cause excessive wear.

Checking Chain Tension

• Cold Check: When the chain is cold, you should be able to pull the chain away from the bar about 1/8 inch.
• Hot Check: After cutting for a while, the chain will expand due to heat. Check the tension and adjust as needed.

Adjusting Chain Tension

• Loosen the bar nuts: Use the wrench that came with your chainsaw to loosen the bar nuts.
• Adjust the tensioning screw: Use the screwdriver or wrench to adjust the tensioning screw until the chain has the proper tension.
• Tighten the bar nuts: Tighten the bar nuts securely.
