The numbers on a chainsaw bar can be found on the backside of the bar. It should be a six or seven digit number that can also include a combination of both letters and numbers (e. g. H30DD028). It is important to note the size, type, and make of the bar when identifying it, as different manufacturers use different numbering systems.
Additionally, some bars have the numbers printed on the side of the bar near the nose, and other bar models have the number stamped into the bar. It is also important to note that some manufacturers may use the same bar numbers for different bar lengths.
The number can be used to identify the type of bar, the size of the bar, the bar length, and even the year the bar was manufactured in. For example, the number “H30DD028” on an Oregon chainsaw bar, indicates it is a durable-high grade bar and is 28 inches in length.
How do you measure the length of a bar?
The most efficient and accurate way to measure the length of a bar is to use a digital caliper. A digital caliper is a precision measuring device that uses an internal spring-loaded mechanism to accurately measure the outside, inside, and depth dimensions of an object.
To measure the length of a bar, place one of the caliper jaws on one end of the bar and the other jaw on the other end. Once both jaws are in contact, hold the caliper firmly and press the caliper’s button.
The digital readout will show the length of the bar, accurate to within a few thousandths of an inch or a few tenths of a millimeter. If you don’t have access to a digital caliper, you can use a ruler to measure the bar.
Place the ruler along one side of the bar, and record the length. You can measure multiple points along the bar, and then average the measurements to give your best estimate of the actual length. However, it is important to remember that measurements with a ruler are not as precise as a digital caliper, and could have a higher margin of error.
How do you read a chainsaw bar number?
To read a chainsaw bar number, you need to understand the numbering system that is used to identify the length and gauge of the bar. A standard chainsaw bar is numbered in two parts, usually separated by a slash.
The part before the slash (on the left) will give you the length of the bar in inches. The part after the slash (on the right) will give you the “gauge,” which is how thick the bar is. For example, a bar that is marked 16/06 means it is 16 inches long and 6 gauge (or 0.
06 inch thick). If there are two sets of numbers instead of just one, the one on the right will represent the pitch of the chain. Each saw manufacturer has its own system for coding the pitch, so consult the owner’s manual for specifics.
In general, the higher the number after the decimal point, the smaller the pitch.
How do I know what size my chainsaw is?
To know what size your chainsaw is, you will need to consult the owner’s manual. The size is usually printed on the chain cover or the starter handle. You may need to use a ruler or a measuring tape to measure the size of the chain.
The size will also be listed in the owner’s manual in the specifications section of the manual. In addition, if you have an electric chainsaw, the size will be indicated on the rating label, which should be visible on the motor housing.
Generally, electric chainsaws are 12-16 inches in size and gas chainsaws are 16-18 inches in size. However, there may be larger and smaller chain sizes available depending on the model and manufacturer.
What do Stihl bar numbers mean?
Stihl bar numbers are a way of denoting the length and type of guide bar used on Stihl chainsaws. The number is actually composed of two parts: the first number indicates the bar length, while the second part denotes the type of bar.
For example, a Stihl bar number of 18″ (18-inch) would consist of “18” for the bar length, followed by a single letter code indicating the bar type. Some common examples include: E = Pro Laminated Sprocket Nose Bars, M = MicroTec Laminated Bars, P = Picco Micro Mini Bars, and R = Solid Replaceable Sprocket Bars.
The length of the guide bar is usually displayed in inches (18, 20, 24, etc. ), but can also be shown in centimeters (45, 50, 75, etc. ) depending on the product listing. To give you an idea, a Stihl 18″ guide bar would typically be between 453mm – 457mm long.
Additionally, Stihl sells several special bars such as short-nose (. 375″), light (. 325″), slim (. 375″ -. 404″), and Intenz bars (. 325″ -. 375″). These bars are also assigned a letter code so you can easily distinguish them from regular sprocket bar designs.
Overall, the Stihl bar number system provides an easy way of determining the size and type of guide bar you need for your chainsaw.
What does 91 mean on chainsaw chain?
The number 91 stamped on a chainsaw chain refers to the space, or pitch, between the drive links of the chain. Pitch is measured in an eight of an inch, so 91 on a chainsaw chain means that the drive link pitch is.
375″ (3/8″). This number is used to indicate compatibility between the bar, the drive sprocket, and the chain. If the drive link pitch does not match, the chain will not fit and could potentially cause serious damage to the chainsaw.
Therefore, when replacing or upgrading a chainsaw chain it is important that the 91 stamp on the chain is the same as the original. The 91 stamp is typically accompanied by a manufacturer’s number, which should also match the existing chain.
What size file do you use on a 3/8 chain?
A 3/8″ size chain typically requires a 3/8″ pitch sized chain file. This is a standard size file that is available at most hardware stores. Because it is smaller, the 3/8″ pitch file is a good choice for lighter-duty saws and smaller-scale cutting.
It is also useful for keeping the teeth in a chain from becoming too sharp and potentially causing issues with the chain. To use the file, you will need to measure the chain’s gauge and then select the appropriate size.
For example, a. 050 chain requires a. 050 size file. It is important to select the appropriate size for the chain because a file that is too small can do excessive damage, while one that is too big won’t be able to remove the material needed to keep the chain sharp.
What is the difference between .325 and 3/8 chain?
The difference between. 325 and 3/8 chain is the size of the drive link. The drive link is the thick part of the chain that fits into the sprocket. A 3/8” chain has a larger drive link than a. 325” chain, making the 3/8” chain stronger and better able to handle heavier loads.
The trade-off is that the larger size of the 3/8” drive link creates more drag, resulting in reduced engine efficiency and increased fuel consumption. Additionally, the 3/8” chain is slightly more expensive than.325”chain.
Therefore, it is important to determine which chain is better for the specific task at hand. If the task is light duty, such as light sawing, the. 325” chain will be the better choice. However, for more demanding applications such as heavy sawing, the 3/8” chain will be the preferred option.
What does the G stand for Oregon chain?
The “G” in Oregon chain stands for “Gauge. ” This is the measure of the width between inner links in the chain and is also referred to as the “pitch” of the chain. The narrower the chain, the higher the gauge, and the larger the chain, the lower the gauge.
Oregon chain gauge sizes range from 3/8” to 3/4”. A 3/8” chain is typically used in consumer applications and a 3/4” chain is usually used in commercial applications.

How are Oregon chainsaw bars measured?
Oregon chainsaw bars are typically measured by their length, ranging from 10” to 20” in length. The length of a chain saw bar is measured from the tip of the bar to the end of the bar where it meets the engine in the center.
The length of the bar has a direct relationship to the engine size and chain type, which both influence the size of the work area. It is important to match the correct length of the bar with the right engine size to ensure a smoother cutting experience.
When choosing a bar size, it is important to take into account the type of wood being cut, the pitch of the chain, the speed of the engine, and the type of cuts being made. Choosing the wrong size bar can lead to breakage or wear on the engine over time.
Where do you measure chainsaw bar from?
The length of a chainsaw bar is measured from the tip of the guide bar to the housing of the powerhead. This is generally measured in inches and is sometimes referred to as the “nose-to-tail” measurement.
The length of the bar directly affects how deep the saw can cut into the wood, so it’s important to choose a chainsaw bar of the right size in order to best suit the tasks you plan to use it for. When selecting the right chainsaw bar length, you’ll want to consider the log size you plan to cut, the cutting depth that is needed, and the weight of the chainsaw.
Too light of a bar will struggle with large logs and too heavy of a bar may be too cumbersome and difficult to handle.
Is it worth sharpening a chainsaw chain?
Yes, it is worth sharpening a chainsaw chain. Not only can it help to extend the lifespan of the chain, but it can also help to make the chainsaw more efficient. Sharpening a chainsaw chain can make the chainsaw cut better and quicker by making sure that all of the teeth are sharp and free from any rust, build up, and even dullness.
By sharpening the chain on a regular basis, you can ensure that it works efficiently and also that it is safe to use. Additionally, by properly maintaining the chain, you’ll reduce the risk of any kickback from the chain as well as any snagging of branches or materials that can be cut with the chainsaw.
