Choosing the right chainsaw chain replacement is crucial for optimal performance and safety. It involves understanding chain and bar numbers and selecting the appropriate chain size. In this guide, we'll demystify the process, helping you make an informed choice.
1. Understanding Chain Numbers:
Chainsaw chains come with a series of numbers that indicate their specifications.
The most common format is "Pitch-Gauge-Drive Links" (e.g., 3/8"-0.050"-72).
Pitch: The distance between three consecutive rivets divided by two. It's a crucial measurement that must match the sprocket's pitch on the chainsaw.
Gauge: The thickness of the drive links, which fits into the guide bar groove. The gauge must match the groove width on the bar.
Drive Links: The number of individual links that engage with the chainsaw's drive sprocket.
2. Chain Pitch:
Chain pitch determines the size and spacing of the chain's drive links.
Common chain pitches include 3/8", 0.325", and 1/4". Ensure the chain pitch matches the sprocket on your chainsaw.
Smaller chainsaws often use 1/4" or 0.325" pitch chains, while larger saws use 3/8" pitch chains.
3. Chain Gauge:
Chain gauge refers to the thickness of the drive links.
Common gauges include 0.043", 0.050", and 0.063". Ensure the gauge matches the groove width on your guide bar.
Larger chainsaws typically require thicker gauge chains for added durability.
4. Chain Length (Drive Links):
The number of drive links in the chain affects the fit and tension on the bar.
Accurately count the drive links on your old chain or check the chainsaw's manual for the recommended drive link count.
5. Matching Bar and Chain:
Ensure the replacement chain matches the length of your guide bar.
A chain that is too short or too long can lead to safety hazards and inefficient cutting.
6. Additional Considerations:
Choose the type of chain that suits your cutting needs (e.g., full-chisel, semi-chisel, low-profile).
Check if your chainsaw requires a safety chain for certain applications.
Consider the chain's quality and durability, as high-quality chains tend to last longer.
7. Consult the Manual:
Always refer to your chainsaw's manual for specific chain replacement recommendations.
It may provide guidance on suitable chain types, sizes, and maintenance.
Conclusion:
Buying the correct chainsaw chain replacement involves understanding chain and bar numbers, chain pitch, gauge, drive links, and ensuring a proper fit with your chainsaw's guide bar. Taking these factors into account will help you choose the right chain for safe and efficient cutting operations while extending the life of your chainsaw.

Have you ever needed a new chainsaw chain, called a supplier, and realised there is far more to ordering a new chain than just quoting your chainsaw's Make, Model and Bar length? This is most probably not because you chose a bad supplier, it's because there is sometimes a specific set of numbers you need to quote to them before they are sure they are supplying you with the correct chain.
In this video I show you the which numbers are correct, and where to find them on your chainsaw.
