Measuring the chain size on a chainsaw is essential for guaranteeing optimum efficiency and security. An inaccurately sized chain can result in decreased chopping effectivity, elevated put on and tear, and potential hazards. Understanding the correct measuring approach is crucial for any chainsaw consumer to take care of their tools and function it successfully.
To start measuring the chain, find the drive sprocket and the bar tip. The drive sprocket is the gear situated on the base of the noticed, whereas the bar tip is the top of the information bar reverse the drive sprocket. Depend the variety of drive hyperlinks that match between these two factors. Drive hyperlinks are the hyperlinks that join the chopping tooth to the chain. The variety of drive hyperlinks you depend will correspond to the right chain size in your chainsaw.
After getting decided the variety of drive hyperlinks, check with your chainsaw’s proprietor’s handbook to search out the suitable chain pitch. Chain pitch is the gap between the facilities of two consecutive rivets on the chain. Frequent chain pitches for chainsaws embrace 0.325 inches, 3/8 inches, and 0.404 inches. Multiply the variety of drive hyperlinks by the chain pitch to calculate the whole chain size in inches. For instance, should you counted 50 drive hyperlinks and the chain pitch is 0.325 inches, the whole chain size could be 50 x 0.325 = 16.25 inches.
Figuring out Chain Size by Measuring the Noticed Bar
Measuring the Noticed Bar Size
When figuring out the chain size, begin by measuring the noticed bar, the metallic information that holds the chain. To do that, you may want a measuring tape or ruler.
* Place the noticed bar on a flat floor. Be certain the noticed bar is straight and stage, not twisted or bent.
* Measure the size of the noticed bar. Place the measuring tape or ruler on the base of the noticed bar, the place it meets the chainsaw’s physique. Prolong the measuring instrument to the tip of the noticed bar, excluding the nostril sprocket.
* Report the measurement. Be aware down the size in inches or centimeters.
Figuring out Chain Measurement
After getting the noticed bar size, you possibly can decide the matching chain measurement. Confer with the chainsaw producer’s suggestions or seek the advice of a sequence compatibility chart. The chart sometimes lists the suitable chain size for every noticed bar measurement.
Instance:
| Noticed Bar Size | Chain Size |
|—|—|
| 16 inches | 56 Drive Hyperlinks |
| 18 inches | 60 Drive Hyperlinks |
| 20 inches | 64 Drive Hyperlinks |
Figuring out Chain Pitch, Gauge, and Drive Hyperlink Depend
1. Figuring out Chain Pitch
The pitch of a chainsaw chain refers back to the distance between the facilities of adjoining drive hyperlinks. It’s sometimes measured in inches or millimeters, with widespread pitches together with 0.325″, 0.375″, and 0.404″. To measure the chain pitch:
- Maintain the chain taut.
- Depend the variety of drive hyperlinks inside a 12-inch part.
- Divide the variety of drive hyperlinks by 12 to find out the pitch.
2. Figuring out Chain Gauge
The gauge of a chainsaw chain signifies the thickness of the drive hyperlinks. It is usually measured in inches or millimeters, with widespread gauges being 0.050″, 0.058″, and 0.063″. To measure the chain gauge:
- Find the narrowest a part of a drive hyperlink.
- Measure the thickness of this slim part.
- The ensuing measurement represents the chain gauge.
| Gauge (inches) | Thickness (inches) |
|---|---|
| 0.050 | 0.030 |
| 0.058 | 0.042 |
| 0.063 | 0.050 |
3. Figuring out Drive Hyperlink Depend
The drive hyperlink depend refers back to the whole variety of drive hyperlinks in a chainsaw chain. To depend the drive hyperlinks:
- Find the start line of the chain (marked by a connecting hyperlink or a distinct shade).
- Depend every drive hyperlink as you progress alongside the chain till you attain the start line once more.
- The overall depend represents the drive hyperlink depend.
Utilizing a Chainsaw to Measure Chain Size
When your chainsaw chain turns into uninteresting or broken, it is essential to measure its size to make sure you buy the right substitute. Here is a step-by-step information on how one can measure chain size utilizing a chainsaw:

| 16 | 27 |
| 18 | 29 |
| 20 | 31 |
Wrap the Chain Across the Template
Place the template across the chainsaw bar, guaranteeing the chain is taut and the tooth are dealing with the right route. Align the top of the chain with the marked measurement on the template.
Measure the Chain with a Measuring Tape
If a template just isn’t out there, use a measuring tape to find out the size of the chain. Begin by aligning the zero mark of the measuring tape with the top of the chain. Measure alongside the chain, following the contour of the tooth, till you attain the top of the chain. Be aware the measurement displayed on the measuring tape.
Benefits of Utilizing a Template or Measuring Tape
Using a template or measuring tape affords a number of benefits:
- Accuracy: Each strategies present exact measurements, guaranteeing the chain is lower to the right size.
- Comfort: Templates and measuring tapes are available and straightforward to make use of, making the method handy and environment friendly.
- Consistency: Utilizing templates or measuring tapes ensures constant measurements, lowering the probability of inconsistencies that would result in incorrect chain size.
- Time-Saving: These instruments get rid of the necessity for guesswork and repetitive measurements, saving effort and time through the upkeep course of.
Chain Size Measuring Choices
| Technique | Benefits | Disadvantages |
|---|---|---|
| Template | Exact, handy, constant | Requires particular template for chainsaw mannequin |
| Measuring Tape | Versatile, available | Barely much less correct, extra time-consuming |
Measuring Chain Size
Chainsaw chains are available quite a lot of lengths to accommodate totally different sized chainsaws. Utilizing the flawed size chain can harm the noticed or pose a security hazard. You will need to measure the chain size accurately earlier than putting in it in your noticed. Listed here are some tips about how one can do it:

Ideas for Correct Chain Size Measurement
Measuring the size of your chainsaw chain is essential to make sure correct efficiency and security. Observe the following pointers for correct measurements:
Depend the Drive Hyperlinks
Drive hyperlinks are the parts that interact with the sprocket on the chainsaw bar. To depend them, place the chain on a flat floor and depend the variety of tooth that match between two consecutive rivets.
Measure the Bar Groove
The bar groove is the channel the place the chain runs. Measure the size of the groove from the tip of the bar to the top. Subtract 1 inch (2.5 cm) to account for the overlap between the chain and the bar.
Calculate the Chain Size
After getting the drive hyperlink depend and bar groove size, calculate the chain size utilizing the next components:
| Method | ||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Chain Size = (Drive Hyperlink Depend + 2) x (Drive Hyperlink Pitch) + (Bar Groove Size – 1 inch)
the place Drive Hyperlink Pitch is the gap between the facilities of two consecutive drive hyperlinks. Think about the Kind of BarSeveral types of bars, corresponding to full-skip and semi-skip, have totally different chain lengths. Test the producer’s specs for the really useful chain size in your bar. Error ToleranceEnable for a small error tolerance of ±1 hyperlink. That is acceptable so long as the chain just isn’t too brief or too lengthy to interact correctly with the bar and sprocket. Visible InspectionAfter getting measured the chain, visually examine it for put on or harm. Worn or broken chains can have an effect on the accuracy of your measurement and ought to be changed. Tips on how to Measure Chain Size on ChainsawObserve these steps to precisely measure the size of your chainsaw chain:
Troubleshooting Frequent Errors in Measuring Chain SizeListed here are some widespread errors that may happen when measuring chain size and how one can keep away from them: Error 1: Counting the flawed hyperlinksBe certain to depend the drive hyperlinks, which have square-shaped tooth.
