WHAT NUMBER IS AN OREGON CHAIN?

 When it comes to maintaining your chainsaw, knowing the correct chain specifications is essential. A well-matched chain ensures optimal performance and safety. If you're looking for the right chain for your chainsaw, you can rely on Westcoast Saw, the go-to online store for all your chainsaw needs. Westcoast Saw specializes in Oregon chains, and this guide will help you identify the appropriate chain for your saw, even if your saw isn't listed in their catalog.



Chain Identification


Before you can order the correct chain, you need to identify the specifications for your saw's chain. There are three primary attributes to consider: the chain number, the number of links, and the chain gauge.


Chain Number


The chain number is a crucial identifier for your chainsaw chain. This number is typically stamped onto the drive tooth and provides you with essential information about your chain. If you're using an Oregon chain, finding the corresponding Oregon chain number is straightforward. However, if you're using a different brand, Westcoast Saw provides a handy conversion chart to help you find the equivalent Oregon number.


Pitch and Gauge


Chain pitch and gauge are also significant factors to consider when identifying your chain. The pitch is the distance between any three consecutive rivets divided by two. Chain pitch defines the size of the chain, and Oregon chains are available in various pitches, including 1/4", .325", 3/8", and .404".


The gauge is the thickness of the drive link where it fits into the guide-bar groove. The chain's gauge must match that of the guide bar for proper operation. Oregon offers various gauge options, such as.043",.050",.058","and.063", or in metric measurements, 1.1mm, 1.3mm, 1.5mm, and 1.6mm. To accurately measure the gauge, a vernier caliper can be quite handy.


Number of Links


The next crucial detail you'll need is the number of links in your chain. Count the drive teeth (circled in the provided picture) to determine this. Having the correct number of links is crucial for your chain to operate smoothly.


Gauge and Pitch to Chain Number


Once you've collected all the necessary information, it's time to identify your chain type and find the perfect match. Refer to the chart below to find the Oregon chain that matches your pitch and gauge specifications:


  • 1/4" Pitch, 0.050" (1.3mm) Gauge: Oregon Chain Number 25

  • .325" Pitch, 0.050" (1.3mm) Gauge: Oregon Chain Number 20

  • .325" Pitch, 0.050" (1.3mm) Gauge: Oregon Chain Number 95

  • .325" Pitch, 0.058" (1.5mm) Gauge: Oregon Chain Number 21

  • .325" Pitch, 0.063" (1.6mm) Gauge: Oregon Chain Number 22

  • 3/8" Pitch, 0.050" (1.3mm) Gauge: Oregon Chain Number 72

  • 3/8" Pitch, 0.058" (1.5mm) Gauge: Oregon Chain Number 73

  • 3/8" Pitch, 0.063" (1.6mm) Gauge: Oregon Chain Number 75

  • 3/8" Pitch, 0.043" (1.1mm) Gauge: Oregon Chain Number 90

  • 3/8" Pitch, 0.050" (1.3mm) Gauge: Oregon Chain Number 91

  • .404" Pitch, 0.063" (1.6mm) Gauge: Oregon Chain Number 59

The Ideal Clutch Cover for Your Chainsaw Machines

  Chainsaws are indispensable tools for various tasks, from landscaping to firewood preparation. However, ensuring their safety and efficiency requires attention to detail, particularly regarding part maintenance. Among these, the clutch cover is a crucial component for optimal performance and safety.

How does a chainsaw kill switch work?

Image
A chainsaw kill switch, also known as a safety switch or an emergency stop switch, is a safety feature that is designed to quickly and easily shut off the chainsaw in case of an emergency. The switch is typically located near the handle of the chainsaw and can be activated by the operator with their thumb or finger. When the kill switch is activated, it interrupts the electrical circuit that powers the chainsaw's motor , causing it to stop running. This is important for a number of reasons. For instance, if the operator loses control of the chainsaw or if the chain becomes stuck, the kill switch can be used to stop the chain from moving before an injury can occur. There are different types of kill switches. A common type is the "dead-man" switch, which is designed to be held down by the operator while the chainsaw is in use. If the operator loses grip on the switch, the circuit is interrupted and the chainsaw stops. Another common type is the "tension" switch, w...
