7 Steps on How to Measure a Chain for a Chainsaw

7 Steps on How to Measure a Chain for a Chainsaw

Determining the correct chain size for your chainsaw is crucial for optimal performance and safety. An improperly sized chain can lead to premature wear, reduced cutting efficiency, and potential hazards. Fortunately, measuring a chain for a chainsaw is a relatively straightforward process that can be accomplished with a few simple steps. In this guide, we will provide detailed instructions on how to accurately measure your chainsaw chain, ensuring that you have the right fit for your specific model.

The first step in measuring a chainsaw chain is to count the number of drive links. Drive links are the individual links that engage with the sprocket on the chainsaw’s powerhead. To count the drive links, place the chain on a flat surface and carefully separate the links. Start counting from one end of the chain and continue until you reach the other end. The total number of drive links you count will determine the correct replacement chain size for your chainsaw.

Once you have counted the number of drive links, you can use the following formula to calculate the chain’s pitch: Pitch = Number of Drive Links / 2. The pitch is a measurement that represents the distance between any three consecutive rivets on the chain. Chainsaws typically have a pitch of either 3/8″, .325″, or 1/4″. By determining the pitch, you can ensure that the replacement chain you purchase has the correct spacing to fit properly on your chainsaw’s sprocket. Additionally, you should also check the gauge of the chain, which refers to the thickness of the drive links. The gauge is typically measured in inches and should match the gauge of the original chain to ensure proper fit.

Identifying the Proper Chain Length

Determining the correct chain length for your chainsaw is crucial for ensuring optimal performance and safety. Several factors influence the chain’s length, including the chainsaw’s bar length, the number of drive links, and the pitch. To accurately measure the chain, follow these steps:

1. **Measure the Bar Length:** Use a measuring tape or ruler to determine the length of the chainsaw bar from the tip of the nose to the end of the groove where the chain fits. Record this measurement in inches or centimeters.

2. **Count the Drive Links:** Remove the chain from the chainsaw and lay it out on a flat surface. The drive links are the protruding, tooth-shaped links that engage with the sprocket on the bar’s nose. Count the number of drive links on the chain.

3. **Calculate the Chain Length:** Use the following formula to determine the proper chain length:

Bar Length (inches) Drive Link Count
12 50-52
14 54-56
16 58-60
18 62-64
20 66-68
22 68-70
24 70-72
26 72-74

Locating the Guide Bar’s Drive Link Count

To accurately measure the chain for your chainsaw, you need to determine the number of drive links on your guide bar. Follow these steps:

  1. Inspect the guide bar: Look for a series of numbers stamped or etched onto the narrow side of the guide bar, near the nose.
    Example Guide Bar Markings
    16″ 325-72

    In this example, “325” represents the pitch, “72” is the number of drive links, and “16” is the length of the bar.

  2. Visual count: If the guide bar does not have markings, you can count the number of drive links manually. Hold the bar horizontally with the teeth facing up and count the number of connecting links between the two rivet heads. Drive links typically have an oblong hole for securing the chain to the bar.
  3. Use a worksheet: Some chainsaw manufacturers provide a worksheet or chart that indicates the number of drive links based on the model number or length of the guide bar. Refer to your chainsaw’s user manual or consult the manufacturer’s website for this information.

Determining the Pitch and Gauge

Before measuring the length of a chainsaw chain, you need to determine its pitch and gauge. These measurements are required to ensure you purchase the correct replacement chain.

Pitch

The pitch of a chainsaw chain refers to the distance between adjacent drive links. It is measured in inches, and common pitches include 0.325", 0.375", and 0.404".

To measure the pitch, count the number of drive links within a 6" segment of the chain. Divide the number of drive links by 2 to get the pitch in inches.

For example, if you count 16 drive links within a 6" segment, the pitch would be 16 ÷ 2 = 0.325".

Gauge

The gauge of a chainsaw chain refers to the thickness of the drive links. It is typically measured in millimeters, with common gauges being 0.043", 0.050", and 0.058".

To measure the gauge, use a caliper or a gauge tool to measure the width of a drive link at its thickest point.

Gauge (mm) Approximate Inch Measurement
0.043 0.017"
0.050 0.020"
0.058 0.023"

Measuring the Length Using a Tape Measure

Finding the Exact Chain Length

To determine the precise chain length required for your chainsaw, you must:

  1. Remove the Chain: Detach the chain from the chainsaw by following the manufacturer’s instructions.

  2. Straighten the Chain: Uncoil and straighten the chain on a flat surface to ensure accuracy.

  3. Measure Total Drive Links: Using a tape measure, count and measure the length of all the drive links, which are the longer rectangular links. Record this measurement (A).

  4. Calculate Chain Length: To determine the chain length, follow these steps:

    • Determine the pitch value of your chainsaw (e.g., 0.325 inches).
    • Multiply the pitch value by the number of drive links counted in step 3 (e.g., 0.325 inches x 70 links = 22.75 inches).
    • Add 1-2 inches for the connecting link(s) (e.g., 22.75 inches + 1.5 inches = 24.25 inches).

  5. Round to Nearest Inch: The calculated length may not be an exact inch measurement. Round it up or down to the nearest whole inch for accuracy.

Pitch Value Example Calculation Example Length
0.325 inches 0.325 inches x 70 links + 1.5 inches 24.25 inches
0.375 inches 0.375 inches x 68 links + 1.5 inches 26.25 inches

Adding Extra Length for Overlap

To ensure a secure and reliable fit, it is essential to add extra length to the chain for overlap. This overlap allows the chain to properly engage with the bar and drive sprocket, reducing the risk of jumping or derailment.

The amount of overlap required varies depending on the type of chain and bar combination. However, as a general rule of thumb, it is recommended to add approximately 1 to 1.5 inches (2.5 to 3.8 cm) of extra length to the chain.

To calculate the total length of chain needed, including the overlap, follow these steps:

  1. Measure the length of the bar from the tip to the base.
  2. Add 1 to 1.5 inches (2.5 to 3.8 cm) to the bar length.
  3. Divide the total length by the pitch of the chain to determine the number of drive links required.

Remember that it is always better to err on the side of caution by adding slightly more overlap than necessary. Excess overlap can easily be adjusted and removed after installation.

Bar Length Recommended Overlap Total Chain Length
16 inches 1.25 inches 17.25 inches
18 inches 1.5 inches 19.5 inches
20 inches 1.75 inches 21.75 inches

Calculating the Specific Link Count

To determine the precise link count for your chainsaw chain, follow these steps:

1. Gather Materials: You will need a ruler or measuring tape, a hook tool, and safety gloves.

2. Prepare the Chain: Remove the chain from the chainsaw and ensure it is clean and free of debris.

3. Find the Starting Link: Locate the link that has a “drive link” and an “idler link” connected. The drive link will have two teeth, while the idler link has one.

4. Mark the Starting Point: Use a felt-tip marker or other visible indicator to mark the starting link.

5. Measure the Pitch: Measure the distance between the centers of three consecutive rivets. Divide this value by 2 to obtain the pitch of the chain (in inches).

6. Count the Links: Starting from the marked starting link, count every third rivet. Each set of three rivets represents one link (inclusive of the starting link).

7. Multiply by the Pitch: Multiply the link count by the pitch to calculate the overall length of the chain in inches:

Length (in) = (Link Count) x (Pitch)

Considering the Nose Sprocket

The nose sprocket is a small, gear-like component located at the tip of the chainsaw’s bar. Its primary function is to guide the chain around the tip of the bar and ensure that it remains in place during operation. The nose sprocket is typically made of hardened steel for durability, and its size and shape vary depending on the chainsaw model and intended use.

When measuring a chain for a chainsaw, it’s crucial to consider the nose sprocket. The correct chain length ensures proper fit and performance, preventing damage to the sprocket or the chain itself.

The nose sprocket has a specific number of teeth, which corresponds to the number of drive links in the chain. Drive links are the links that engage with the sprocket and pull the chain around the bar. The number of drive links in a chain is typically indicated in the chain’s description or on the packaging. To determine the appropriate chain length, you need to match the number of drive links in the chain to the number of teeth on the nose sprocket.

For example, if the nose sprocket has 7 teeth, you would need a chain with 7 drive links. To ensure accuracy, it’s recommended to consult your chainsaw’s operator’s manual or refer to the manufacturer’s specifications for the specific chain length required for your particular chainsaw model and nose sprocket configuration.

Chain Length and Number of Teeth

Teeth on Nose Sprocket Chain Length (Drive Links)

Record the measurement in inches or centimeters. It’s important to ensure that the measuring tape or ruler is held straight and parallel to the bar for an accurate reading. Additionally, clean the bar of any sawdust or debris before taking the measurement to prevent any discrepancies.

Identifying the Guide Bar Length

Determining the appropriate guide bar length for your chainsaw requires a thorough understanding of the vital role it plays in the overall performance. The length of the guide bar directly influences the depth of cut capacity and the overall balance of the chainsaw. Identifying the correct bar length ensures optimal cutting efficiency and safety.

Typically measured in inches, the guide bar length is a crucial specification that should be carefully considered before purchasing or using a chainsaw. It is not uncommon for manufacturers to offer a variety of bar lengths for each chainsaw model, accommodating different cutting requirements and user preferences.

For general-purpose cutting tasks, such as firewood preparation, a guide bar length of 16 to 18 inches is often recommended. However, for heavy-duty applications, a longer bar, ranging from 20 to 24 inches, may be necessary to handle larger logs and thicker branches. It’s important to choose a bar length that is appropriate for the intended use, considering factors such as tree size, cutting frequency, and operator experience.

The following table provides a general guide to bar length selection based on common cutting applications:

Cutting Application Recommended Bar Length (inches)
Domestic use (firewood, small trees) 14-18
General-purpose (medium-sized trees) 16-20
Heavy-duty (large trees, thick branches) 20-24

Measuring Bar On Chainsaw

The Importance of Using a Rail

For the first method, we use the chainsaw’s bar to make a quick and convenient measurement. However, the accuracy of this method depends on the length of the bar.

Using a rail involves choosing a straight and flat object as a reference. This could be a piece of wood, a metal bar, or a level. Place the rail alongside the chainsaw’s bar and extend it beyond the tip. Then, measure the distance from the center of the chainsaw’s sprocket to the end of the rail.

The rail method provides a more precise measurement because it eliminates the possibility of error introduced by the curvature of the chainsaw’s bar.

Measuring a Standard Guide Bar

To measure a standard guide bar, follow these steps:

  1. Determine the pitch: Locate the pitch stamped on the bar’s side. Common pitches include 3/8-inch, .325-inch, and .404-inch.
  2. Measure the length: Place the bar on a flat surface. Measure the distance from the tip to the tail of the bar, excluding the sprocket hole.
  3. Measure the gauge:
    • For 3/8-inch pitch bars: Use a thickness gauge or ruler to measure the thickness of the drive links. The gauge measurement is the width of the groove on the bar where the drive links ride. Common gauges for 3/8-inch pitch bars include .050-inch, .058-inch, and .063-inch.
    • For .325-inch and .404-inch pitch bars: Measure the distance from the top of a drive link to the bottom of a tie strap on the same link. The gauge measurement is half of this distance. Common gauges for these bars include .050-inch and .063-inch.

Measuring a Carving Bar

Measuring a carving bar is a simple process that can be done in a few minutes. By following these steps, you can ensure that you have the correct size bar for your chainsaw.

1. Gather your materials.

You will need a measuring tape, a pencil, and the chainsaw bar that you want to measure.

2. Clean the bar.

Use a wire brush or a rag to clean any dirt or debris from the bar. This will make it easier to see the measurements.

3. Find the tip of the bar.

The tip of the bar is the pointed end that is used for cutting. Position the measuring tape at the tip of the bar.

4. Measure the length of the bar.

Hold the measuring tape taut and measure the distance from the tip of the bar to the other end. This is the length of the bar.

Here are the different types of carving bars and their typical lengths:

Carving Bar Type Length (inches)
Regular carving bar 10-16
Mini carving bar 6-9
Specialty carving bar 17+

Using a Tape Measure

If you don’t have a ruler or measuring tape, you can still measure the bar on your chainsaw using a tape measure. First, identify the tip of the bar and the base of the bar. The tip is the pointed end of the bar, while the base is the flat end that attaches to the saw.

Once you have identified the tip and base of the bar, hold the tape measure against the bar so that the zero mark on the tape measure is aligned with the tip of the bar. Then, pull the tape measure out until it reaches the base of the bar. The measurement on the tape measure at the base of the bar is the length of the bar.

Here are some tips for measuring the bar on your chainsaw using a tape measure:

  1. Make sure that the tape measure is straight and not twisted.
  2. Hold the tape measure against the bar so that it is parallel to the bar.
  3. Pull the tape measure out until it reaches the base of the bar.
  4. Read the measurement on the tape measure at the base of the bar.
  5. Round the measurement up to the nearest inch or centimeter.

Example: If the measurement on the tape measure at the base of the bar is 18.5 inches, then the length of the bar is 19 inches.

Tape Measure Measurement Bar Length
18.5 inches 19 inches
20.25 inches 21 inches
22.0 inches 22 inches

Utilizing a Measuring Stick

Measuring with a Measuring Stick is a simple and precise method to determine your chainsaw’s bar length. Here are the steps to follow with further details:

  1. Choose a suitable measuring stick: Select a rigid measuring tool like a ruler, tape measure, or even a straight wooden stick.
  2. Locate the bar tip: Hold the measuring stick perpendicular to the ground and align its zero-point with the tip of the bar.
  3. Measure to the base of the saw body: Extend the measuring stick along the bar, ensuring it remains parallel to the ground. Stop when you reach the base of the saw body, where the bar attaches.
  4. Record the measurement: Note down the distance between the bar tip and the base of the saw body. This number represents the length of the chainsaw bar.
  5. Consider wear and tear: If the chainsaw has seen extensive use, the bar may have worn down slightly. To account for this, subtract a small amount from the measured length. Typically, 1/16th to 1/8th of an inch is a reasonable deduction.
  6. Rounding the measurement: Since chainsaw bar lengths are typically available in whole or half-inch increments, round your measurement to the nearest appropriate value. For example, if you measure 18.6 inches, round it to 19 inches.

Verifying Measurements with a Saw Chain

Once you have a rough estimate of your bar length, you can verify it using a saw chain. Here are the steps:

  1. Wrap the chain around the bar. Make sure the chain is snug but not too tight.
  2. Mark the point where the chain meets itself. This will be the length of your bar.
  3. Measure the distance between the mark and the end of the bar. This will be the length of your bar in inches.
  4. Compare your measurement to the manufacturer’s specifications. The length of your bar should be within 1/4 inch of the specified length.
  5. If your measurement is off by more than 1/4 inch, you may need to adjust the tension of your saw chain.
  6. If you are still having trouble getting an accurate measurement, you can take your chainsaw to a professional for help.

Here is a table that summarizes the steps for verifying measurements with a saw chain:

Step Description
1 Wrap the chain around the bar.
2 Mark the point where the chain meets itself.
3 Measure the distance between the mark and the end of the bar.
4 Compare your measurement to the manufacturer’s specifications.
5 If your measurement is off by more than 1/4 inch, you may need to adjust the tension of your saw chain.
6 If you are still having trouble getting an accurate measurement, you can take your chainsaw to a professional for help.

Laser Measurement High Laser distance meter

Each method provides varying degrees of accuracy and practicality, so select the one that best suits the specific requirements of the measurement task.

Bar Length Measurement

When measuring the bar length, it’s crucial to include the length of the cutting teeth. The cutting teeth extend past the bar’s body, so disregarding them will result in an inaccurate measurement. Measure from the tip of the cutting teeth to the nearest mounting hole on the chainsaw body.

Common Measurement Mistakes to Avoid

1. Measuring from the Wrong End

Don’t measure from the tip of the bar that connects to the chainsaw body. Instead, start measuring from the opposite end, where the chain exits the bar.

2. Failing to Include Cutting Teeth

As mentioned earlier, neglecting the cutting teeth will lead to a shorter measurement than the actual bar length.

3. Not Using a Precise Measuring Tool

Avoid using a worn-out or inaccurate measuring tape or ruler. Ensure you have a reliable tool that will provide accurate measurements.

4. Measuring Along the Side of the Bar

The bar length should be measured from the top or bottom of the bar, not along the side. Measuring along the side will result in a shorter measurement.

5. Mistaking Nose Radius for Bar Length

Some chainsaws have a rounded nose section at the tip. This nose radius should not be included when measuring the bar length. Measure from the tip of the cutting teeth.

6. Measuring Without the Chain Installed

Install the chain on the bar before measuring. The chain’s presence can slightly alter the bar length.

7. Not Cleaning the Bar

Before measuring, clean the bar to remove any dirt or debris that could affect the accuracy of the measurement.

8. Using the Wrong Mounting Holes

If your chainsaw has multiple mounting holes, use the ones closest to the tip of the bar. Measuring from the wrong holes will result in an inaccurate length.

9. Not Considering Bar Angle

Some chainsaws have bars with angled tips. When measuring these bars, be sure to follow the manufacturer’s recommendations for measuring the correct length. Typically, the bar length is measured from the point where the bar meets the body to the tip of the longest cutting tooth, along the top or bottom surface of the bar.

Safety Precautions During Measurement

When measuring the bar on your chainsaw, it is important to take the following safety precautions:

1. Wear appropriate safety gear

This includes gloves, safety glasses, and ear protection.

2. Make sure the chainsaw is off and the chain is not moving

This will prevent you from accidentally cutting yourself.

3. Position the chainsaw on a stable surface

This will help prevent the chainsaw from moving while you are measuring it.

4. Use a tape measure or ruler

Do not use your fingers to measure the bar, as this could result in injury.

5. Measure the bar from the tip to the base

This will give you the total length of the bar.

6. Be aware of the bar’s width

The width of the bar will determine what size chain you need to purchase.

7. Inspect the bar for damage

Look for any cracks, bends, or other damage that could affect the performance of the chainsaw.

8. Replace the bar if it is damaged

A damaged bar can be dangerous and should be replaced immediately.

9. Clean the bar before storing it

This will help prevent rust and corrosion.

10. Store the chainsaw in a dry, safe place

This will help protect the chainsaw from damage and keep it in good working condition.

How To Measure Bar On Chainsaw

To measure the bar on a chainsaw, you will need a measuring tape. Start by measuring the length of the bar from the tip of the nose to the base of the bar. This will give you the length of the bar in inches. You can also measure the width of the bar at the widest point. This will give you the width of the bar in inches.

Once you have measured the length and width of the bar, you can use this information to purchase a new bar for your chainsaw. When purchasing a new bar, it is important to choose a bar that is the same length and width as the bar that you are replacing. This will ensure that the new bar fits properly on your chainsaw.
