Stens 266-298 OEM Replacement Belt Compatible with/Replacement for Husqvarna K770 Cut-Off saws 2011-2017 544908406 Multi-Ribbed Belt Type, Drive Belt Application,Black

What It Is

This is a multi-ribbed drive belt designed for Husqvarna K770 cut-off saws (2011–2017 models). It transfers power from the engine to the cutting blade, making it a critical wear item for concrete, asphalt, and metal cutting applications.

Fitment & Compatibility

• Direct fit for: Husqvarna K770 cut-off saws built between 2011 and 2017 (OEM part number 544908406).
• Not compatible: K770 saws manufactured before 2011 or after 2017, or other Husqvarna models.
• Check before buying: Measure your old belt’s length (rib count and overall circumference) if possible. Stens 266-298 is a multi-ribbed belt—verify your saw uses the same rib type. Confirm your saw’s serial number range matches the 2011–2017 production window.
• Aftermarket note: Stens is an aftermarket brand; it’s not OEM but meets OEM specs. It’s a direct replacement—no modification needed.

Key Things to Know

• Quality: Stens belts are known for consistent tension and durability, but they may not last as long as an OEM Husqvarna belt in heavy daily use.
• Installation difficulty: Moderate. You’ll need to remove the blade, blade guard, and belt cover. A belt tension tool is recommended; overtightening can damage pulleys.
• Common gotcha: Some K770 saws have a belt tension spring that must be compressed correctly during installation—refer to your saw’s manual.
• Price vs. OEM: At ~$24, it’s about 30–40% cheaper than the Husqvarna OEM belt, making it a solid budget option for occasional users.

Should You Buy It

Buy this if you own a 2011–2017 Husqvarna K770 and need a reliable, affordable replacement for light-to-medium use. For daily professional cutting, consider the OEM belt for longer life. If your saw is older or newer than the 2011–2017 range, skip this and verify your exact model first.
