Replacement Pruner Chainsaw Chain for Stihl GTA 26 – 4-Inch Mini Saw Chain Set

Replacement chain fitment for the Stihl GTA 26

This replacement pruner chainsaw chain is intended for the Stihl GTA 26 mini saw using the matching 4-inch setup. It is a direct replacement style chain for the original GTA 26 pruning saw chain identified by the OEM reference numbers listed below.

If you are replacing a worn, dull, or damaged chain on a GTA 26, the most important step is matching the chain details exactly to your current bar-and-chain combination.

Will this chain fit your saw?

This chain is made for the Stihl GTA 26 and replaces the following OEM chain references:

• Stihl 71PM328
• Stihl 71PM3 28
• Stihl 71 PM3 28
• Stihl 3670 000 0028
• Stihl 36700000028
• Stihl 3670-000-0028

It is also described as replacing:

• 3670 005 0028
• 36700000028

When confirming fit, check these four points on your current saw setup:

• Saw model: This listing is specifically for the Stihl GTA 26
• Bar length: This product is for the 4-inch mini saw chain set
• Pitch: Match the pitch stamped on the bar or listed in your saw documentation
• Gauge: Match the chain gauge to the bar groove size
• Drive-link count: Your existing chain must have the same number of drive links as the original replacement chain reference

Because mini saw chains are very size-specific, even a small mismatch in pitch, gauge, or drive-link count can prevent proper fit. If your current chain or packaging shows any of the OEM numbers above, that is the strongest confirmation that this is the correct replacement chain for your GTA 26.

If your saw is not a GTA 26, or if the chain on your tool uses different markings than the part numbers listed here, do not assume compatibility. Verify against the bar markings or the original chain before ordering.

Replacing the chain

Replacing a GTA 26 chain is straightforward, but safety matters. Follow these basic steps:

1. Power the tool off completely and remove the battery before doing any chain service.
2. Loosen and remove the sprocket cover so the old chain can be taken off the bar and drive sprocket.
3. Inspect the bar and sprocket area for packed sawdust, oil residue, or damage, and clean as needed.
4. Install the new chain in the correct cutting direction, making sure the drive links sit properly in the bar groove and around the drive sprocket.
5. Reinstall the bar cover and set chain tension so the chain is snug on the bar but still moves freely by hand.
6. Rotate the chain by hand carefully to confirm smooth travel, then reinstall the battery and test at low load before regular use.

A chain that is too loose can derail. A chain that is too tight can wear the bar, chain, and drive components faster.

Keeping it sharp

A small pruning chain works best when it is kept clean and sharp. A few habits help a lot:

• Avoid cutting dirty wood or letting the chain contact soil, rocks, or metal, since this dulls cutters very quickly.
• Check chain tension often, especially after installing a new chain, because a fresh chain may settle in during early use.
• Clean debris from the bar groove and cover area so the chain can run smoothly and seat properly.

If cutting speed drops and you find yourself forcing the saw through branches, it is usually time to sharpen or replace the chain.

FAQ

Does this chain fit every Stihl mini chainsaw?

No. This listing is specifically for the Stihl GTA 26 and the OEM chain references listed on this page. Match the exact saw model and chain markings before ordering.

How do I confirm I have the right replacement?

Check your current chain or original packaging for one of these references: 71PM328, 71PM3 28, 71 PM3 28, 3670 000 0028, 36700000028, or 3670-000-0028. Also confirm that your saw uses the 4-inch bar setup.

Can I keep using the chain if it is dull but not broken?

You can, but performance and safety usually suffer when a chain becomes dull. A dull chain cuts slower, generates more heat, and can put extra strain on the saw. Replacing it promptly helps maintain smooth pruning performance.
