How you can Measure Chainsaw Bar Size
Measuring the size of a chainsaw bar is essential for guaranteeing optimum efficiency and security. The bar size determines the slicing capability of the chainsaw and influences its maneuverability. This is a complete information that will help you precisely measure the size of your chainsaw bar, guaranteeing you’ve gotten the proper measurement for the job.
Measuring the Bar Size
To measure the bar size, find the information bar, which is the lengthy metallic half that holds the chain. Maintain the chainsaw upright, with the information bar pointing vertically. Measure the gap from the tip of the bar to the bottom the place it connects to the chainsaw physique. Use a measuring tape or a ruler positioned towards the bar to acquire the precise size. It is necessary to notice that the bar size doesn’t embrace the size of the chain.
Figuring out the Variety of Drive Hyperlinks
The variety of drive hyperlinks straight influences the slicing size of the chainsaw. To find out the variety of drive hyperlinks, discuss with the next steps:
- Determine the pitch: Measure the gap between three consecutive rivets alongside the chain, in inches or millimeters. The pitch is the center-to-center distance between rivets.
- Depend the variety of slicing hyperlinks: Depend the variety of enamel or cutters on the chain. The slicing hyperlinks are those with the sharp, slicing edges.
- Calculate the whole variety of drive hyperlinks: Subtract the variety of slicing hyperlinks from the whole variety of hyperlinks within the chain. The result’s the variety of drive hyperlinks.
For instance, if the chain has 20 whole hyperlinks, 12 slicing hyperlinks, and a pitch of three/8 inches, the variety of drive hyperlinks is calculated as follows:
Complete hyperlinks – slicing hyperlinks = drive hyperlinks
20 – 12 = 8 drive hyperlinks
Subsequently, the chain has 8 drive hyperlinks. It is important to match the right size of the bar with the variety of drive hyperlinks to make sure optimum efficiency and security.

| Chain Measurement | Pitch | Variety of Complete Hyperlinks | Variety of Slicing Hyperlinks | Variety of Drive Hyperlinks |
|—|—|—|—|—|
| 3/8″ | 0.375″ | 20 | 12 | 8 |
| .325″ | 0.325″ | 30 | 18 | 12 |
| 1/4″ | 0.25″ | 18 | 10 | 8 |
Inspecting the Bar for Harm
Earlier than measuring the chainsaw bar, it is essential to examine it for any harm which will have an effect on its efficiency or security. Study the bar completely for the next points:
1. Bent or Twisted Bar
A bent or twisted bar could cause the chain to derail or skip, resulting in harmful conditions. Verify for any noticeable bends or twists alongside the bar’s size.
2. Worn or Broken Sprocket Nostril
The sprocket nostril is the a part of the bar that engages with the noticed’s drive sprocket. Examine the nostril for extreme put on or harm, as it may have an effect on the chain’s drive and effectivity.
3. Free Bar Nuts
The bar nuts maintain the bar securely to the chainsaw. Free nuts can permit the bar to maneuver or come off throughout operation, posing a big hazard. Verify and tighten the nuts as wanted.
4. Cracked or Damaged Bar Rails
Cracks or breaks within the bar rails can weaken the bar and compromise its integrity. Examine the rails fastidiously for any indicators of injury or deformation.
5. Worn Out Groove
The groove within the bar the place the chain runs needs to be easy and free of damage. Extreme put on could cause the chain to derail or prematurely put on out. Verify the groove for any indicators of unevenness or extreme put on.
6. Bent or Broken Oil Holes
Oil holes permit lubrication to achieve the chain and bar. Bent or broken oil holes can prohibit the movement of oil, resulting in elevated friction and put on. Examine the oil holes for any obstructions or harm.
7. Deformation or Warping
Extended use or improper storage could cause the bar to deform or warp. This will have an effect on the chain’s monitoring and might result in untimely put on or different issues. Examine the bar fastidiously for any indicators of deformation or warping by inserting it on a flat floor and checking for any unevenness or curvature.
How you can Measure a Chainsaw Bar
Measuring a chainsaw bar is necessary for guaranteeing that you’ve got the proper measurement bar to your noticed. The incorrect measurement bar could make it tough to make use of the noticed successfully and might even harm the noticed.
To measure a chainsaw bar, you should measure the size of the bar from the tip of the nostril to the top of the tail. The size of the bar is often measured in inches or centimeters.
Along with the size, you must also measure the width of the bar. The width of the bar is often measured in millimeters. The width of the bar will decide the kind of chain that you should use with the noticed.
After you have measured the size and width of the bar, you should use this info to buy the proper measurement bar to your noticed.
