County Line Chainsaw Chain Fit Guide: 5 Expert Tips for Smooth Cuts
Choosing the correct chainsaw chain is more than just picking one off the shelf. It’s about understanding your saw, the type of wood you’re cutting, and the specific demands of the job. A mismatched chain can lead to poor performance, increased wear and tear on your saw, and even dangerous kickback. I’ve seen it happen, and I want to help you avoid those pitfalls.
1. Understanding the Basics: Key Chain Components
Before diving into the specifics of County Line chains, let’s cover the fundamental parts of a chainsaw chain. These are the building blocks of a smooth and efficient cutting experience.
- Cutters: These are the teeth that do the actual cutting. They come in various shapes and sizes, each designed for different types of wood and cutting styles. I’ve found that chisel cutters are excellent for clean, fast cuts in softwood, while semi-chisel cutters are more durable and better suited for hardwood and dirty wood.
- Tie Straps: These connect the cutters and drive links, providing structural integrity to the chain.
- Drive Links: These fit into the guide bar groove and are propelled by the chainsaw’s sprocket, pulling the chain around the bar. The number of drive links is crucial for proper chain length.
- Depth Gauges (Rakers): These control the amount of wood each cutter takes with each pass. Proper depth gauge filing is essential for smooth cutting and preventing kickback. I once spent an entire afternoon meticulously filing depth gauges, and the difference in cutting performance was remarkable.
- Rivets: These hold all the components together.
2. Identifying Your Chainsaw’s Specifications: The Foundation of Chain Selection
The first, and arguably most crucial, step is to determine the exact specifications of your chainsaw. This information is usually found in the owner’s manual or on a sticker located on the saw itself. Don’t guess! Accuracy is paramount.
- Chain Pitch: This is the distance between any three consecutive rivets divided by two. Common pitches include 3/8″ (0.375″), .325″, and 0.404″. I’ve seen people try to force a chain with the wrong pitch onto a saw, and it never ends well. It’s like trying to fit a square peg in a round hole.
- Data Point: A study by Oregon Tool (a leading chain manufacturer) found that using the correct chain pitch can increase cutting efficiency by up to 15%.
- Chain Gauge: This is the thickness of the drive links, which must match the groove width of the guide bar. Common gauges include .043″, .050″, .058″, and .063″. Using the wrong gauge can cause the chain to bind or derail.
- Data Point: A chain gauge that is too small for the guide bar groove can lead to excessive wear on both the chain and the bar, reducing their lifespan by as much as 30%.
- Number of Drive Links: This is the total number of drive links in the chain. This is essential for ensuring the chain fits properly on the guide bar.
- Personal Experience: I once ordered a chain online without verifying the number of drive links. When it arrived, it was too short, and I had to go through the hassle of returning it. Learn from my mistake!
- Guide Bar Length: This is the length of the guide bar, measured from the tip to where it enters the chainsaw body. The correct chain length is directly related to the guide bar length.
- Technical Limitation: Exceeding the recommended guide bar length for your chainsaw can overload the motor and potentially damage the saw.
How to Find These Specifications:
- Consult the Owner’s Manual: This is the most reliable source of information.
- Check the Chainsaw Body: Look for a sticker or plate with the specifications.
- Examine the Guide Bar: Some guide bars have the pitch and gauge stamped on them.
- Count the Drive Links: If you have an old chain, you can count the number of drive links.
- Use a Chain Gauge Tool: This tool can accurately measure the pitch and gauge of the chain.

- Data Point: Properly filed depth gauges can improve cutting efficiency by up to 20%.
- Chain Cleaning and Lubrication: Clean your chain regularly with a brush and solvent to remove dirt and debris. Lubricate the chain with chainsaw bar and chain oil before each use.
- Practical Tip: I often soak my chains in kerosene overnight to remove stubborn sap and grime.
- Material Specification: Use only high-quality chainsaw bar and chain oil to prevent premature wear and tear.
Common Sharpening Mistakes to Avoid:
- Filing at the Wrong Angle: This can damage the cutters and reduce cutting efficiency.
- Filing Too Deep: This can weaken the cutters and make them more prone to breaking.
- Ignoring the Depth Gauges: Improper depth gauge height can cause the chain to grab or chatter.
5. Troubleshooting Common Chain Fit Issues: Diagnosing and Resolving Problems
Even with careful selection and maintenance, you may encounter issues with your chainsaw chain fit. Here are some common problems and their solutions.
- Chain is Too Loose:
- Cause: The chain has stretched, the guide bar is worn, or the tensioning mechanism is loose.
- Solution: Tighten the chain tensioning mechanism. If the chain is excessively stretched, it may need to be replaced. Check the guide bar for wear and replace it if necessary.
- Practical Example: I once had a chain that kept loosening after only a few cuts. I discovered that the tensioning mechanism was stripped and needed to be replaced.
- Chain is Too Tight:
- Cause: The chain is new and hasn’t stretched yet, the temperature is cold, or the tensioning mechanism is too tight.
- Solution: Loosen the chain tensioning mechanism. Allow the chain to warm up before adjusting the tension.
- Chain Keeps Derailing:
- Cause: The chain gauge is incorrect, the guide bar is worn, the drive sprocket is worn, or the chain is damaged.
- Solution: Ensure the chain gauge matches the guide bar groove width. Replace the guide bar or drive sprocket if they are worn. Inspect the chain for damage and replace it if necessary.
- Data Point: A worn drive sprocket can reduce chain speed by up to 10%.
- Chain Cuts Unevenly:
- Cause: The cutters are not sharpened evenly, the depth gauges are not properly filed, or the guide bar is bent.
- Solution: Sharpen the cutters evenly and file the depth gauges to the correct height. Check the guide bar for straightness and replace it if necessary.
- Chain Smokes Excessively:
- Cause: The chain is not properly lubricated, the chain is too tight, or the wood is very dry.
- Solution: Ensure the chain oil reservoir is full and the oiler is functioning properly. Loosen the chain tension slightly. Use a chain designed for dry wood.
- Material Specification: For dry wood, consider using a chain with a hardened cutting surface to reduce wear.
Case Study: The Case of the Mismatched Chain
I once worked with a small logging operation that was experiencing frequent chain failures. After investigating, I discovered that they were using chains with the wrong pitch for their saws. They had been relying on a generic chain chart that didn’t account for the specific models of their chainsaws. By switching to the correct pitch chains, they were able to significantly reduce chain failures and improve their overall productivity. This highlights the importance of verifying the specifications of your chainsaw and choosing the correct chain accordingly.

Understanding Wood Moisture Content: Key to Successful Firewood Preparation
Moisture content is a critical factor in firewood quality and burning efficiency. Properly seasoned firewood burns hotter, cleaner, and produces less smoke. I’ve learned that taking the time to dry firewood properly is well worth the effort.
- Ideal Moisture Content: Firewood should have a moisture content of 20% or less for optimal burning.
- Technical Limitation: Burning firewood with a moisture content above 20% can lead to creosote buildup in your chimney, increasing the risk of chimney fires.
- Drying Time: Drying time varies depending on the type of wood, the climate, and the storage conditions. Hardwoods typically take longer to dry than softwoods.
- Data Point: A study by the University of Maine found that hardwoods can take up to 12 months to dry properly, while softwoods can dry in as little as 6 months.
- Measuring Moisture Content: You can use a moisture meter to accurately measure the moisture content of firewood.
- Practical Tip: Split a piece of firewood and measure the moisture content on the freshly exposed surface.
- Storage Conditions: Store firewood in a well-ventilated area, off the ground, and covered to protect it from rain and snow.
- Visual Example: (Include a diagram showing proper firewood storage techniques)
Wood Selection Criteria:
- Hardwoods vs. Softwoods: Hardwoods generally provide more heat per volume than softwoods.
- Density: Denser woods burn longer and produce more heat.
- Ease of Splitting: Some woods are easier to split than others.
- Availability: Choose woods that are readily available in your area.
Cord Volume:
- A standard cord of firewood is 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet.
- Precise Measurement: When stacking firewood, ensure that the pieces are tightly packed to maximize the volume of wood in the cord.
Original Research: Chainsaw Chain Performance in Various Wood Types
I conducted a personal research project to compare the performance of different County Line chainsaw chains in various wood types. I used a controlled setup with a calibrated chainsaw and measured the cutting time for each chain in oak, maple, pine, and fir.
