Product Information

Full details

The Husqvarna Bar & Chain Kit X-Precision SP11G (529921060) is designed for arborists and professional tree care workers who demand high cutting precision and efficient performance from their pole saws or chainsaws. This kit provides a seamless upgrade or replacement solution by bundling a high-quality guide bar, two X-Precision SP11G saw chains, and a matching 1/4 inch mini spur sprocket (9T) for optimal power transfer; however, users should verify compatibility with their specific Husqvarna model to ensure the drive sprocket and bar mount match their powerhead.

FAQs

Can I use this kit on any Husqvarna chainsaw?

No, this kit is specifically designed for models compatible with a 1/4 inch pitch and 9T sprocket drive system.

Why does the kit include two chains?

The two-chain setup allows you to swap to a fresh, sharp chain instantly, keeping your equipment running while the dull one is sharpened.

How often should I flip the guide bar?

It is recommended to flip the bar every time you switch chains to ensure even wear on the top and bottom rails.

Is the 1/4 inch pitch suitable for felling large trees?

No, this kit is designed for precision work, pruning, and light-duty tasks, not for felling or bucking large-diameter timber.

How do I know if the sprocket needs replacing?

If you notice deep grooves worn into the sprocket teeth (greater than 0.5mm), it is time to replace it to prevent premature chain wear.

Troubleshooting

Chain comes off the guide bar frequently

Check chain tension; 1/4 inch chains have less mass and can derail if run too loose.

Cuts are drifting to one side

Inspect the bar rails for uneven wear or verify that the chain was sharpened evenly on both sides.

Sprocket noise or grinding

Ensure the 9T sprocket is fully seated and the clutch bearing is properly lubricated.

Pros and Cons

Pros

  • Comprehensive kit includes all necessary parts for a full drive system refresh
  • Two included chains allow for longer uptime while the other chain is being sharpened
  • Husqvarna original equipment ensures perfect fitment and safety standards
  • 1/4 inch pitch allows for ultra-narrow kerf and surgical cutting accuracy

Cons

  • Limited compatibility; strictly for specific Husqvarna models supporting 1/4 inch pitch
  • Requires professional installation for those unfamiliar with sprocket replacement
  • Higher maintenance requirement due to the fine nature of 1/4 inch chains

Setup, Compatibility & Care

Installation of the sprocket requires removing the side plate of the chainsaw or pole saw and utilizing the appropriate clutch tool to remove the existing sprocket. Ensure that the bar groove is thoroughly cleaned of debris before mounting the new bar. To maximize the life of the kit, rotate between the two included chains to ensure even wear on the drive links and sprocket. Always maintain proper lubrication by checking your oil reservoir frequently, as small-pitch chains generate heat faster and rely heavily on consistent bar oil flow. Regularly inspect the bar rails for burrs and file them flat to maintain a stable cut.
