To measure a chainsaw’s effective cutting length (or simply, “length”): Place a tape measure at the very tip of the bar. Measure straight back to the point where the bar enters the chainsaw body. Round that measurement up to the nearest even number.
How is chain size measured?
Measuring the size of a chain requires a simple tool such as a set of calipers. Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
Can I put a 20 inch bar on a 18 inch chainsaw?
A chain saw engine turns a sprocket. Changing the bar and chain on your 18-inch chain saw to a 20-inch size will enable easier cutting of larger trees and branches. Larger chain saws cut through thicker trees and limbs. Put work gloves on to protect your hands and fingers.
What does 72 mean on a chainsaw chain?
72 = 3/8 pitch .050 gauge or 1.3mm. 73 = 3/8 pitch .058 gauge or 1.5mm.
How do you calculate chain pitch?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
What size chain do I need?
After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more. An 18 inch chain would feel too tight.
Can you swap chainsaw bars?
Yes, but you need a bar designed to fit on your saw. There are different designs for different saws, and the bar has to match the chain/sprocket configuration as well.
Will any bar fit a chainsaw?
Not every bar or chain is right for every saw. That’s why electric saws use bars 18″ and shorter. Similarly, chainsaw chains are measured to fit certain bars. Try to fit a chain onto a bar that’s too narrow or too long, and you’ll find that your saw simply won’t work.
What size bars does STIHL make?
STIHL guide bars range from 10″ (found on our tree-trimming pole pruners) to an incredible 59″ (used in extreme felling operations).
What’s the difference between 404 and 3/8 chain?
Secondly, the numbers 3/8″ and . 404″ refer to the pitch (distance) between the drive links – these are the bits on the chain that stick down and engage with the drive sprocket on the saw, and the sprocket on the roller-nose end of the bar.
What chainsaw chain cuts the fastest?
A full chisel chain is a chain with square cornered teeth, and they’re known for being the fastest cutting blade shape available. A full chisel chain also has a higher number of teeth than other chain options(full chisel is also known as a standard chisel chain).
What do Stihl chain numbers mean?
Find the gauge of the chain by locating the number stamped on the drive link. A 1 equals a 0.043-inch gauge, 3 equals a 0.050-inch gauge, 5 corresponds to a 0.058-inch gauge, 6 means the chain has a 0.063-inch gauge. A 0 means the chain has a 0.080-inch gauge, but this gauge size is found only on the Harvester chain.
What is chain pitch length?
Chain length is measured in discreet units called links. The length of each link is the same as the pitch length. A #25 chain has a pitch length of ¼”. It is sometimes necessary to fix the center-to-center distance of the sprockets to accommodate existing constraints or mechanical design considerations.
How do I know what size my sprocket is?
The sprocket size represents the first two digits in the chain designation. Example: 40A14 is size 40. The number of teeth represents the last two digits in the chain designation. Count the number of teeth.
How do you pick a sprocket size?
Determine the number of teeth of the small sprocket. The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is recommended. The number of teeth on the large sprocket should be less than 120.
How do I know what kind of sprocket I have?
Number of sprocket teeth or sprocket diameter. . . The easiest way to determine the number of teeth is simply to count them. Sometimes, however, the teeth are totally worn away. In this event, the caliper diameter may assist in identifying the sprocket.
Is a 22 inch chain too long?
For example, if a man’s neck is 17 inches, then a 19 inch necklace would be the smallest size expected to fit comfortably. This length necklace can be worn inside or outside a shirt. 22 Inch. Another very common length for a man’s necklace, it can work nicely a cross, dog tag, or other pendant is added to the chain.
How long is a 20 inch chain on a woman?
20″: A 20″ necklace falls a few inches below the collarbone, perfect for women who want some breathing room with their chain. This length chain works best with a higher neckline.
Are chainsaw bars universal fit?
AdvertisementsA: Chainsaw bars are not universal. Instead, bars are specific to a chain type and have different, incompatible mounts. More specifically, chainsaw bars vary both in mount geometry as well as in intended chain pitch and gauge, which must match those of your saw and chain.
How does bar length affect chainsaw?
Most chainsaws ship with a guide bar that is reasonably sized relative to the saw capacity, but could actually run a longer one. Swapping the original bar for a longer model is often useful, as it may give you just the bit of additional cutting capacity you need in felling or bucking.
