Reading an Oregon chain requires being familiar with a few basic concepts. First, you need to know the different types of Oregon chains. Oregon chains come in multiple pitches, with the most common size being the semi-chisel chain, which is characterized by a round, small drive link.
You can also find narrow kerf, skip tooth, and full-complement chains. It is important to use the right chain for the right application, as using the wrong chain can damage the saw and saw chain.
Next, you need to know how to identify the chain size numbers. The numbers are typically separated by dashes, such as “3/8″ –. 050”, which indicates a 3/8 inch pitch chain with. 050 inch gauge. Additionally, Oregon chains often have a match code stamped on the drive links of the chain, which includes a combination of letters and numbers.
This match code helps indicate the chain’s features, such as the pitch, the link count, the gauge, and the type of cutting edge.
Finally, you should understand how to correctly match the Oregon chain to your chainsaw. When selecting a saw chain you need to ensure it fits the pitch, gauge, and length of the current chain. You should also make sure the style of chain matches the specific design of your chainsaw, such as a semi-chisel or full complement.
Matching the saw chain correctly can help your chain cut efficiently and help prevent kickback and saw damage.
What do the numbers on an OREGON chainsaw chain mean?
The numbers on an OREGON chainsaw chain refer to the type of cutting chain it is and the size of the chain itself. The first number refers to the gauge of the chain, which refers to the thickness of the drive links, which are the links that are used to drive the chain.
The second number is the pitch of the chain, which is the distance between any three consecutive rivets divided by two, and is measured in 1/8th inch increments. The third number is the number of drive links in the chain, which is typically between 50 and 100.
The fourth number is the cutter type and type of drive link used in the chain. The fifth number is the type of grind used. The sixth number is the bit size, which refers to the diameter of the screws used to mount the chain onto the saw.
How can I tell what gauge my chain is?
To determine what gauge your chain is, you will need to measure the chain’s width. This can be done using either a caliper to measure the overall width of the chain, or a chain gauge tool to measure the width of just the chain links.
For standard chain widths, the measurements would be as follows: 1/8-inch chain = 8.7mm / 9/32-inch chain = 11.1mm / 11/128-inch chain = 8.7mm / 3/16-inch chain = 11.9mm. However, if the chain is a non-standard size, the only way to accurately determine the size is through measurement.
Additionally, if the chain is already installed, it may be difficult to measure, so you may want to opt for a chain gauge tool, as this will make it easier.
What size chain is an OREGON 91?
The OREGON 91 is a size 91 drive-link chain and is commonly used on chainsaws. It is 25.4 cm (10 inches) in length and has 91 drive links. It is suitable for a wide range of chainsaws, including Husqvarna, Stihl, and Jonsered, ranging from models with 35cc to 70cc engines.
The OREGON 91 is designed to be used in combination with the OREGON bar and sprocket system, and is pre-stretched to help maintain tension while in use. It is made with a durable construction consisting of a hardened steel design and hardened tie straps to ensure a long-lasting, effective performance.
Additionally, the chain has a series of options depending on the type of cut, such as a full-skip, low-kickback and semi-chisel cutters.
What does the G mean on Oregon chain?
The “G” on Oregon chain means that the chain is comprised of Oregon’s special gauge links. Oregon chain products feature unique, proprietary features and advanced designs that help reduce wear, enhance performance, and improve efficiency.
The “G” represents the proprietary gauge design, achieved after years of research and development by Oregon. Oregon’s special gauge chain is created to optimize the chipper chain design process, reduce wear, and improve chain life.

What size file do you use on a 3/8 chain?
For a 3/8 chain, you will typically use a 0.325-inch pitch file size. The pitch of a chain is the distance between any three consecutive rivets divided by two. Although the pitch of a 3/8” chain is 0.
375-inch, it is recommended to use a 0.325-inch file size to lessen the risk of over filing and damaging the drive links. Additionally, the 0.325-inch file size offers a greater degree of patience which enables a smooth filing process.
How do I identify my OREGON chainsaw bar?
Identifying the size of your OREGON chainsaw bar may be necessary when replacing the bar and chain, ordering a file guide, or learning which bar and chain combinations you can use with your saw. To accurately identify the correct size and style of your OREGON chainsaw bar, you’ll need to locate the OREGON model number printed on the bar itself.
The OREGON product number is typically stamped on the bar towards the bar tip, opposite of the bar mount. Most likely, you’ll see a decal printed that includes the logo and model information, and the product number may be printed below the logo.
The product number will have a prefix of R or P, followed by a set of numbers or alpha-numeric characters to indicate the model type and size.
Once you have the OREGON product number, you can use it to discover the size and style of the bar. The first part of the product number will indicate the bar’s length. The last two digits of the product number will indicate the bar’s style.
For example, a product number beginning with 91 will indicate the bar is 91 cm in length and the last two digits may be a 05, indicating the bar is a MCCS. Cross-referencing the product number to an OREGON catalog or online product lookup will provide you with additional detail and clarity of the exact OREGON chainsaw bar you own.
What is the difference between .325 and 3/8 chain?
The difference between. 325 and 3/8 chain is the size of the drive links. The. 325 chain, also known as low profile chain, is about 7/16, or 11.1mm, in size. The 3/8 chain is about. 404, or 10.3mm, in size.
This difference in size affects the speed and power of the chain saw. The. 325 chain is designed to be lighter and faster. It has an increased top speed, but it will lack power when compared to a 3/8 chain.
On the other hand, the 3/8 chain has slightly more torque and power, but it will be heavier and slower than the. 325 chain. Ultimately, it depends on the type of job that you are planning on doing. If you are cutting a large tree or cutting a hardwood, then the 3/8 chain may be the way to go.
However, if you are cutting softer wood or a smaller tree, the. 325 chain would be the better option.
What chainsaw pitch is best?
When it comes to selecting a chainsaw pitch, it is important to consider a few different factors, such as the type of project you are working on and the size of the material you are cutting. For smaller projects and cutting material that is no more than 11” in diameter, a 3/8″ pitch is usually the best choice.
This type of pitch is ideal for light pruning, limbing, and general cutting and is suited to small, electric saws as well as larger, gas-powered saws. For larger projects such as cutting firewood and felling trees, a.
404″ pitch is usually the best choice. This type is suitable for big, heavy-duty saws and delivers more power for efficient cutting of larger pieces of material. The. 404″ pitch is also necessary when cutting material that is more than 11” in diameter.
Ultimately, choosing the right chainsaw pitch is based on the project at hand and the size of the material you will be cutting.
How do I use Oregon chainsaw file guide?

Do Oregon bars fit STIHL saws?
Yes, Oregon bars fit STIHL saws. Oregon is one of the leading manufacturers of chainsaw bars and saw chain in the United States, and as such has a wide range of sizes, lengths, and pitches that are compatible with different STIHL saws.
Oregon bars are designed to provide added control and reduce kickback, offering users versatility and power for their cutting needs. Most bars come pre-drilled for combination chains, so the user does not need to re-drill the bar for different saws.
The most common length for an Oregon bar to fit on a STIHL saw is a 20” bar, however, other sizes are available to meet the requirements of any STIHL saw. Generally, Oregon bars fit STIHL saws with minimal effort and users are able to switch between different bars to meet their sawing needs.
What pitch are STIHL chains?
STIHL chains are designed for a specific pitch, which is typically either a. 325 inch or a. 375 inch. The. 325 inch pitch is a low-profile, narrow-groove chain commonly used in residential chainsaws and the.
375 inch is a wider-groove chain typically used in professional and forestry chainsaws. Generally, lighter-duty chainsaws will use a. 325 inch pitch and heavier-duty models will use the. 375 inch pitch.
The pitch size of the chain also determines the size of the drive sprocket, as the two must match. It is important to check your chainsaw’s owner’s manual to be sure which pitch fits your chainsaw.
How do I know what chain to buy for my STIHL chainsaw?
To determine the right chain for your STIHL chainsaw, you should look at the owner’s manual or the product label found on the chainsaw. The manual or label will likely indicate the size of the chain gauge (thickness), the chain drive link count, and the chain pitch.
Once you have obtained this information, you can use it to determine the correct chain for your chainsaw. You can also consult your local STIHL dealer for assistance or to see what type of chains are available for your particular chainsaw.
When shopping for chains, it is important to make sure that the chain is compatible with your application, as most STIHL chainsaws do not accept all types of chains. Lastly, always use a STIHL-branded chain for optimal performance and dependability.
Can I use a Husqvarna chain on a STIHL?
No, you cannot use a Husqvarna chain on a STIHL chainsaw. Even though they are both designed as chainsaws, they are designed to use different parts and accessories to ensure compatibility with their specific models.
STIHL chainsaws require chains with blades specifically designed for STIHL saws. The size of the chain, number of teeth on the drive sprocket, and the overall design of the blade are different for each saw.
This means that the teeth on a Husqvarna chain wouldn’t properly fit a STIHL chainsaw, so using them together could seriously damage the saw and even make it unsafe to use. Additionally, chains for each brand must be specially made for each model, so even if the chains were compatible, it’s unlikely that Husqvarna would make a chain that fits a STIHL.
