Which Bar Mount Does My Chainsaw Have? An Aussie Bar Fitment Guide
The bar mount is the bit that decides whether a new bar bolts straight onto your saw or sits in the shed useless. Get it right and the bar, chain and sprocket all line up; get it wrong and nothing fits, no matter how good the gear is. This guide walks you through finding your mount in a few minutes, then matches it to your saw so you can order with confidence.
How to identify your bar mount in 3 steps
You don't need to pull the saw apart. Most people sort this out at the kitchen table with the saw on a towel and a phone torch.
Step 1 — Find your saw's model number. This is the single most useful thing to know. On a Stihl it's usually moulded into the plastic near the rear handle or on the starter cover (for example "MS 261"). On a Husqvarna it's on a sticker or moulded panel on the side of the housing (for example "455 Rancher" or "372XP"). Echo, Makita, Dolmar and the rest stamp or sticker theirs in a similar spot. If the saw's faded, the model is often printed on the bar itself or on the chain box it came in.
Step 2 — Look at the bar mounting slot and plate. Take the existing bar off (two nuts on the clutch cover). Flip it over and look at the tail end that sits against the saw. You'll see the long adjuster slot, the oil hole, and the bolt slots. The width of that slot, where the oil hole sits, and the gap between the bolt holes are what define the mount family. You don't need to measure it to the millimetre — matching by model in Step 3 is far easier — but a clear photo of the bar tail is gold if you ever need us to check it.
Step 3 — Match it to a mount family below. Find your saw's brand and model in the mount sections that follow. The mount code (like D025 or A074) is what bar makers use to tell families apart. Once you know your family, every bar listed for that family will physically bolt on — you then just match the bar length, pitch and gauge to your chain.
That's the whole job. The model number does most of the heavy lifting, so if you've got that, you're 90% there.
D025 / SN mount — Stihl 12mm pattern (3003)
This is the workhorse Stihl mount, covering most mid-size and large Stihl saws from the old 024 right through to the current MS 661. It's the "3003" pattern with a 12mm slot, and it's by far the most common Stihl mount on Aussie properties.

K095 / UHL mount — Husqvarna 8.2mm small pattern
This is the small-to-mid Husqvarna mount (also written UHLX), with a narrower 8.2mm slot than the big D009 above. It covers the popular farm and homeowner Huskies like the 455 Rancher and the 346XP, plus a long list of Dolmar, Makita, Alpina and Oleo Mac saws built on the same footprint.

E099 / SLD mount — large Stihl 3002 pattern (14mm)
This is the heavy-duty Stihl mount with a wider 14mm slot — the "3002" pattern. It's for the big-bore felling and milling saws, both the modern MS 880 / MS 881 and the older 050 through 090 range. If you're running long bars and milling hardwood, this is where you'll be.
Stihl: 050, 051, 070, 075, 076, 084, 088, 090, MS880, MS881

Match by use case
Sometimes you know what you do with the saw better than you know the model number. Here's the quick way to land in the right ballpark — then confirm the exact mount from the sections above before you order.
| What you cut | Typical saws | Likely mount family | Sensible bar length |
|---|---|---|---|
| Homeowner / firewood — light pruning, branches, small rounds | Stihl MS170, MS180, MS250; small Husqvarna (135, 140) | A074/SW (Stihl) or K095/UHL (Husqvarna) | 12–16 inch |
| Hobby farmer / property — fence lines, fallen trees, regular firewood | Stihl MS261; Husqvarna 455 Rancher | D025/SN (Stihl) or K095/UHL (Husqvarna) | 16–20 inch |
| Professional / felling — big timber, all-day cutting, milling | Stihl MS400, MS461; Husqvarna 372XP, 395XP | D025/SN (Stihl) or D009/HV (Husqvarna) | 20–32 inch |
A couple of practical notes. Don't over-bar a small saw — a 20-inch bar on a homeowner saw bogs down and pulls the chain through too slow, which dulls it faster. And the heavier you work the saw, the more the chain choice matters: for hardwood and high hours, tungsten carbide tipped chains hold their edge far longer than standard steel, which is the difference between sharpening every tank and sharpening every few weeks.
Bar, chain and sprocket must match
This is the one that trips people up, so it's worth being clear. The bar, the chain and the drive sprocket all have to run the same pitch. Pitch is the spacing of the chain's drive links — if those three parts don't agree, the chain won't seat in the bar groove or wrap the sprocket properly.
Run a mismatch and you get chain jumping, premature wear, chewed-up sprockets and bar rails, and in most cases it voids your warranty. Two parts matching out of three isn't good enough — it has to be all three. The bar groove also has to match your chain gauge (the thickness of the drive link), and the bar tip and length suit the chain's drive-link count.
The simplest way to stay out of trouble: when one part wears out, replace it with the same pitch and gauge spec it already was, or change all three together as a matched set. If you're not sure what you're running, send us a photo and we'll work it out.
FAQ
How do I tell which mount my Stihl has?
Start with the model number — it's usually moulded near the rear handle or on the starter cover. Small Stihls like the MS170, MS180 and MS250 run the A074/SW mount. Most mid-size and large Stihls (MS260 up to MS661) run the D025/SN mount. The big milling and felling saws like the MS880/MS881 run the E099/SLD mount. Find your model in the sections above and you've got your family.
Will a Husqvarna bar fit a Stihl?
No. Husqvarna and Stihl use different bar mount patterns, so a Husqvarna bar won't bolt onto a Stihl (and vice versa). They're not interchangeable. Match the bar to your saw's own mount family — D025/SN, D009/HV, K095/UHL, A074/SW, E099/SLD or D176/EX — not to another brand.
What's the difference between the D025 and A074 mounts?
Both are Stihl, but they're different size classes. The A074/SW is the small Stihl mount (the 3005 pattern) for homeowner and top-handle saws like the MS170 and MS250. The D025/SN is the larger Stihl mount (the 3003 pattern, 12mm slot) for mid-size and pro saws like the MS261, MS400 and MS661. A bar from one will not fit the other, so always confirm by your model.
Where is the model number on my saw?
On a Stihl, look near the rear handle or on the starter/recoil cover — it's usually moulded into the plastic. On a Husqvarna, check the moulded panel or sticker on the side of the housing. Echo, Makita and Dolmar are similar. If it's worn off, the model is often printed on the bar or on the box the chain came in.
I can't find my saw model in your lists — what now?
No worries. Take a clear photo of the tail end of your existing bar (the part that bolts to the saw, showing the slot and oil hole) and the saw's model number if you can read it, and send it through. We'll match the mount for you. You can also run it through our Chain Finder tool to narrow it down.

If gauge ever comes up while you're matching a chain to that bar, here's the inch-to-mm pairing you'll see stamped on chains and printed on bars: .043 (1.1mm), .050 (1.3mm), .058 (1.5mm), .063 (1.6mm), .080 (2.0mm). Always match the bar groove to your chain gauge.
Still not sure? We'll sort it for you
The fastest way to get this right: send us a photo of your bar tail (the end that bolts to the saw) and your saw's model number, and we'll match the mount, bar and chain for you. Give us a call on 0431 183 421 or run it through the Chain Finder tool to narrow it down yourself.
For more on getting the spec right, have a look at our chainsaw guide blog for bar-length and chain-size articles, or jump straight to the chainsaw chains and bars collection. When you do upgrade, our tungsten carbide tipped chainsaw chains and bars hold their edge up to 10x longer than standard steel in hardwood — less sharpening, more cutting.
