S57 Chainsaw Chain Drive Links: 56 Vs 57 Explained (Pro Tips)

Imagine this: you’re deep in the woods, the scent of pine heavy in the air, the roar of your chainsaw echoing as you fell a massive oak. You’ve spent years honing your skills, becoming one with the rhythm of the forest. But even the most seasoned woodcutter can stumble over the seemingly simple details. One of those details, often overlooked but crucial, is the drive link count on your chainsaw chain. Specifically, the difference between an S57 chain with 56 drive links versus one with 57. Believe me, I’ve been there, scratching my head in the middle of a job, wondering why my new chain just won’t fit. This article is born from those experiences – the triumphs and the tribulations – and aims to demystify this seemingly small but significant aspect of chainsaw operation. I’ll break down the differences, the implications, and the “pro tips” that will save you time, money, and frustration in the long run.

S57 Chainsaw Chain Drive Links: 56 vs 57 Explained (Pro Tips)

The seemingly insignificant difference between 56 and 57 drive links on an S57 chainsaw chain can be a major headache if you’re not paying attention. It’s not just about the number; it’s about compatibility, performance, and ultimately, the longevity of your chainsaw. Let’s dive deep into the specifics.

What are Drive Links and Why Do They Matter?

Drive links are the small, tooth-like protrusions on the bottom of your chainsaw chain that fit into the groove of the chainsaw bar. They are the engine’s direct connection to the cutting process. The drive sprocket engages these links, pulling the chain around the bar at high speed, enabling the cutting action.

Engagement: Drive links ensure that the chain is properly engaged with the drive sprocket and guided along the bar.
Tension: They contribute to maintaining proper chain tension, which is critical for safe and efficient cutting.
Power Transfer: They are the point where the chainsaw’s power is transferred to the cutting teeth.

If the number of drive links is incorrect, the chain won’t fit properly on the bar. Too few, and it will be too short; too many, and it will be too long and loose, potentially jumping off the bar, causing damage or serious injury.

Understanding the S57 Chain Designation

The “S57” designation refers to a specific type of chainsaw chain, typically indicating its pitch and gauge. These are critical measurements:

Pitch: The pitch is the distance between any three consecutive rivets on the chain divided by two. It’s usually measured in inches (e.g., .325″, 3/8″).
Gauge: The gauge is the thickness of the drive links where they fit into the bar groove. It’s also measured in inches (e.g., .050″, .058″).

For example, an S57 chain is often a .325″ pitch chain with a .050″ gauge. These specifications are vital for ensuring the chain is compatible with your chainsaw bar and sprocket. However, the S57 only defines these two parameters, the third one is the number of drive links, which defines the length of the chain. A .325″ pitch, .050″ gauge chain can have different number of drive links.

The Core Difference: 56 vs. 57 Drive Links

The difference of one drive link might seem negligible, but it directly affects the overall length of the chain and its suitability for your chainsaw.

56 Drive Links: This chain is designed for a slightly shorter bar or a specific chainsaw model that requires that exact length.
57 Drive Links: This chain is designed for a slightly longer bar or a different chainsaw model.

Key Takeaway: Even if the pitch and gauge are correct, the wrong number of drive links will render the chain unusable.

Why the Confusion? Bar Length and Chainsaw Models

The primary reason for the confusion stems from variations in bar length and chainsaw model compatibility. A chainsaw bar’s length determines the required chain length, and thus, the number of drive links.

Bar Length: Chainsaw bars are measured in inches, typically ranging from 12″ to over 36″. A longer bar necessitates a longer chain with more drive links.
Chainsaw Model: Different chainsaw models, even with the same bar length, might require a slightly different number of drive links due to variations in bar mount design and tensioning mechanisms.

Real-World Example: I once purchased a new bar for my Stihl MS 271. I thought I was being diligent by getting the correct length (18″), but I failed to check the drive link count. The original bar used a chain with 68 drive links. The new bar, while the same length, required 72 drive links. The result? A frustrating afternoon and a trip back to the store.

Identifying the Correct Chain for Your Chainsaw

Here’s how to determine the correct chain for your chainsaw:

Consult Your Chainsaw’s Manual: This is the most reliable source. The manual will specify the correct pitch, gauge, and drive link count for your chainsaw model.
Check Your Existing Chain (If Applicable): If you have the original chain, count the drive links. You can also look for stamped markings on the chain itself, which may indicate the specifications.
Measure Your Bar: The bar will often have the recommended chain specifications stamped on it, including the pitch, gauge, and drive link count.
Use a Chainsaw Chain Finder: Many online retailers and chainsaw manufacturers offer chain finders. You input your chainsaw’s make and model, and the finder will identify the correct chain specifications.
Ask an Expert: If you’re unsure, consult with a knowledgeable salesperson at a reputable chainsaw dealer.

Pro Tip: Always double-check the specifications before purchasing a new chain. It’s better to be safe than sorry.

The Consequences of Using the Wrong Chain

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

Inability to Mount the Chain: The most obvious consequence is that the chain simply won’t fit on the bar.
Improper Tensioning: A chain that is too long or too short will be difficult or impossible to tension correctly.
Chain Slippage: A loose chain can slip off the bar during operation, posing a serious safety hazard.
Damage to the Chainsaw: Operating with an improperly tensioned chain can damage the drive sprocket, bar, and even the chainsaw’s engine.
Reduced Cutting Efficiency: A loose chain will vibrate and chatter, reducing cutting efficiency and increasing the risk of kickback.

Personal Anecdote: I once witnessed a colleague attempt to use a chain that was too long on his chainsaw. He managed to force it on, but the chain was so loose that it kept jumping off the bar. Not only was it incredibly dangerous, but it also took him twice as long to complete the job. He ended up damaging the bar and had to replace it.

Practical Examples and Scenarios

Let’s look at some specific scenarios to illustrate the importance of drive link count:

Scenario 1: Replacing a Worn Chain: You have a Stihl MS 170 with a 16″ bar. Your manual specifies a .325″ pitch, .050″ gauge chain with 55 drive links. When purchasing a replacement chain, you must ensure that it matches these specifications exactly.
Scenario 2: Upgrading Your Bar: You want to upgrade the bar on your Husqvarna 455 Rancher from 18″ to 20″. You need to determine the correct chain specifications for the 20″ bar. After consulting the manual or a chain finder, you discover that the 20″ bar requires a .325″ pitch, .058″ gauge chain with 78 drive links.
Scenario 3: Using an Aftermarket Bar: You purchased an aftermarket bar for your Echo CS-590. The bar manufacturer specifies a .325″ pitch, .058″ gauge chain with 72 drive links. Even though the bar length is the same as the original, the drive link count might be different due to variations in the bar’s design.

Pro Tips for Chainsaw Chain Selection and Maintenance

Here are some pro tips to help you select and maintain your chainsaw chain:

Always Use High-Quality Chains: Invest in reputable chain brands like Stihl, Oregon, or Husqvarna. These chains are made from higher-quality steel and will last longer. I have personally found Oregon chains to be a great value for the money.
Sharpen Your Chain Regularly: A sharp chain is a safe chain. Sharpen your chain every time you refuel your chainsaw or when you notice a decrease in cutting performance. I always carry a file and guide with me in the field.
Use the Correct File Size and Angle: Refer to your chainsaw’s manual for the correct file size and angle for sharpening your chain. Using the wrong file can damage the cutting teeth.
Maintain Proper Chain Tension: Check chain tension frequently, especially when the chain is new. A properly tensioned chain should have a slight amount of sag on the bottom of the bar.
Lubricate Your Chain Regularly: Use a high-quality bar and chain oil to keep your chain lubricated. Proper lubrication reduces friction and wear, extending the life of your chain and bar. I prefer using a bio-degradable bar and chain oil to minimize environmental impact.
Clean Your Chainsaw Regularly: Remove sawdust and debris from your chainsaw after each use. This will help prevent clogging and ensure that the chain runs smoothly.
Store Your Chainsaw Properly: Store your chainsaw in a dry place with the chain cover on. This will protect the chain from rust and damage.
Inspect Your Chain Regularly: Look for signs of wear or damage, such as cracked or broken drive links. Replace the chain if you notice any significant damage.

Case Study: Optimizing Firewood Production with the Right Chain

I run a small firewood business on the side, and efficiency is key. I primarily use a Husqvarna 460 Rancher with a 20″ bar. Initially, I was using a standard chain that required frequent sharpening. After some research, I switched to a full-chisel chain with a .325″ pitch, .058″ gauge, and 78 drive links (specifically designed for my bar length). The difference was remarkable. The full-chisel chain cut through wood much faster and stayed sharper for longer, significantly increasing my firewood production rate. The upfront cost was slightly higher, but the increased efficiency and reduced downtime more than made up for it.

Deep Dive: Chain Pitch, Gauge, and Cutter Types

Let’s delve deeper into the technical aspects of chainsaw chains:

Pitch: The pitch affects the speed and smoothness of the cut. A smaller pitch (e.g., .325″) is generally used for smaller chainsaws and softer woods, while a larger pitch (e.g., 3/8″) is used for larger chainsaws and harder woods.
Gauge: The gauge affects the chain’s durability and its ability to withstand wear and tear. A thicker gauge (e.g., .058″) is generally used for heavier-duty applications.
Cutter Types: Chainsaw chains come in various cutter types, each designed for specific applications:
- Full Chisel: These chains have square-cornered cutters that are very aggressive and cut quickly but are more susceptible to damage in dirty or abrasive conditions.
- Semi-Chisel: These chains have rounded-corner cutters that are more durable than full-chisel cutters and are better suited for dirty or abrasive conditions.
- Low-Profile (Micro-Chisel): These chains have small, rounded cutters that are designed for safety and are less prone to kickback. They are often used on smaller chainsaws.

Insights from My Experience: I’ve found that using a semi-chisel chain for cutting firewood is a good compromise between cutting speed and durability. It holds up well to the occasional dirt and debris that inevitably comes into contact with the chain.
