Chainsaw Chain McCulloch 66 DL .325" pitch .050" (1.3 mm) gauge

Replacement saw chain McCulloch 66 DL with .325" pitch and .050" (1.3 mm) gauge is designed for use on compatible chainsaws for cutting wood, pruning, limbing and light felling. The chain features a standard drive link configuration that provides a secure fit on matching guide bars and is intended for routine maintenance and chain replacement to restore cutting performance.

Advantages

The chain offers accurate tooth spacing and consistent cutting geometry for smooth, predictable cuts while maintaining a compact .325" pitch that balances cutting speed and control. With a .050" (1.3 mm) gauge, it fits narrower guide bars commonly used on lighter chainsaws and pruning models, enabling efficient cutting with reduced vibration. The standard drive link design ensures easy installation and compatibility with a range of chainsaw bars built for this pitch and gauge.

Suitable for

• Pruning and trimming of small to medium branches
• Limbing and removing branches from felled trees
• Light felling of small trees
• General-purpose cutting on compatible light chainsaws and pole saws

How to use

Before installation, ensure the chainsaw is switched off, cooled down and disconnected from any power source or spark plug. Inspect the guide bar and sprocket for wear; replace worn components to maintain safe operation. Fit the chain onto the guide bar and drive sprocket following the chainsaw manufacturer's alignment marks and direction of cut. Adjust chain tension according to the manufacturer's specification so the chain moves freely by hand but remains seated on the bar rails. After installing, apply appropriate chain oil and perform a short test cut to check cutting direction and tension, then re-check and adjust as necessary.

Usage recommendations

Maintain sharp cutters for efficient, safe cutting; use a file guide or professional sharpening service when cutters show dulling. Keep the chain properly lubricated and regularly check tension during use. Replace the chain if links are damaged, rivets loosen, or if sharpening no longer restores cutting performance. Follow the chainsaw manufacturer's safety instructions and wear appropriate personal protective equipment while operating.
