Bought the Wrong Chain for Your Husqvarna 240? Here Is How to Get It Right
A Reddit user bought a chain that would not fit his Husqvarna 240 — and discovered the bar had been swapped without his knowledge. Here is how to avoid the same mistake and match chain to bar, not to saw body.

One of the most upvoted posts in r/Chainsaw tells a story that happens far more often than people realize: a beginner bought a chain for his Husqvarna 240 based on the specs printed on the saw body, and it did not fit. The chain was too short, the pitch was wrong, and nothing lined up.
The root cause? The bar had been replaced by a previous owner with a different size, but the saw body still listed the original bar specs. This is incredibly common with used saws, gifted saws, and saws bought at garage sales.
What happened
Reddit user u/jamoss14 explained:
“I was gifted a slightly used Husqvarna 240 from my arborist BIL but it didn’t have a chain on it. There is no information on the bar itself about what size it is, and on the main body of the chainsaw are 3 sizes listed as different bar options. I measured the effective cutting length of the bar and it was around 15, so I assumed it was a 16 inch bar. I got an appropriately sized chain for the 16 inch bar based on specs and I tried to fit it on today. It seems way too tight.”
After 43 comments of troubleshooting, he discovered the real problem:
“The bar was replaced with one that did not match with the body. The body called for a 16 inch bar, 3/8 low profile pitch and 56DL. The bar that was on it was different.”
The mismatch: the body said 3/8 LP pitch, but the replacement bar was .325 pitch with a different drive link count. Even though both bars were roughly the same physical length, the chain specs were completely incompatible.
The lesson: match chain to BAR, not to SAW
This is the single most important rule for buying replacement chains, and the one beginners get wrong most often:
The bar determines the chain specs. Not the powerhead. Not the saw body. Not the owner’s manual (if the bar has been swapped).
The three numbers you need are stamped on the bar itself:
| Spec | What it means | Where to find it |
|---|---|---|
| Pitch | Distance between rivets ÷ 2 | Stamped on bar (e.g., 3/8”, .325”) |
| Gauge | Thickness of drive links | Stamped on bar (e.g., .050”, .043”) |
| Drive links | Total number of drive tangs | Count them, or read from bar stamp |
All three must match. If even one is off, the chain either will not fit on the bar at all, or it will fit loosely and come off under load — which is dangerous.
u/OGIVE provided the exact specs in the thread:
“The online manual shows either a 14 or 15 inch bar was available. That one is likely stamped 3/8, 1.3mm (.050”), 52DL if it is 14”. If it is 15”, it is likely .325, 1.3mm, 64DL.”
u/MasterTardWrangler gave the definitive advice:
“There are 3 factors of importance: pitch (distance between alternating pins), gauge (thickness of the drive link), drive link count (determines length). An 18 inch bar on a Stihl is a different chain than an 18 inch bar on a Husqvarna — the bar determines the chain, period.”
How to read the stamps on your bar
Every guide bar has specs stamped or printed on it — but they wear off over time, especially on older or heavily used bars. If your stamps are illegible:
-
Measure pitch manually. Pick any three consecutive rivets. Measure the distance from the first to the third. Divide by 2. Common results: 3/8” (9.525mm), .325” (8.25mm), 3/8” LP (also 9.525mm but with smaller cutters).
-
Measure gauge with a caliper. Remove the chain and measure the width of the bar groove. Common gauges: .043” (1.1mm), .050” (1.3mm), .058” (1.5mm).
-
Count drive links. Remove the chain, lay it flat, and count every drive link (the small tangs that sit in the bar groove). This number determines chain length.

Husqvarna 240 specific chain specs
The Husqvarna 240 shipped with either a 14” or 16” bar depending on the model variant:
| Bar length | Pitch | Gauge | Drive links | Oregon equivalent |
|---|---|---|---|---|
| 14” | 3/8” LP | .050” (1.3mm) | 52 | 91PX052G |
| 16” | 3/8” LP | .050” (1.3mm) | 56 | 91PX056G |
If your bar is .325 pitch (which the original poster’s replacement bar was), you need a completely different chain — typically a 95VPX series with different drive link counts.
Do not trust the saw body sticker if the bar has ever been replaced. Always verify by reading the bar stamps directly.
What to do if you bought the wrong chain
- Return it. Amazon and most retailers accept chain returns within 30 days.
- Read your bar stamps (or measure manually if worn off).
- Use Oregon’s Chain Finder at ufoundit.oregonproducts.com — enter your measurements and it will show compatible chains. u/CountryMonkeyAZ recommended this tool in the same thread.
- When in doubt, take the bar to a chainsaw shop. They can cut a chain to exact length and verify fitment. u/deleted advised: “Go to a chainsaw shop and have them cut a chain for you. Will probably be cheaper than trying to figure out the right chain.”
