Husqvarna Bar Sprocket Nose for Light Bars

This Husqvarna bar sprocket nose replaces the worn or seized tip on compatible Husqvarna light bars with a replaceable nose. If the bar rails are still straight and square but the nose sprocket is loose, notchy, or locked up, swapping the nose is cheaper than buying a new bar.

When to replace the nose

The nose sprocket takes a beating, especially when you bore cut or work the tip in limbs. Signs it is finished include side-to-side play, a gritty or seized sprocket, chipped teeth, and chain that slows or jumps at the tip.

If the rails are worn, spread, or bent, a new nose will not fix the bar. Check the rails first and only rebuild a bar that is still straight.

Light bars save weight on a long bar, which matters when you are bucking or felling all day. Keeping a good bar body in service with a fresh nose makes that investment last longer.

Rebuilding the bar

Replaceable noses are held in with rivets that are drilled or ground out, then the new nose is riveted in place. Follow the manufacturer's instructions, and grease the nose sprocket through its grease hole if your bar has one. Match the nose to the bar's pitch and model code.

Dress the rails with a bar file after the swap so the chain sits square, and check that the chain still fits the nose sprocket cleanly before you go back to cutting.

Confirm the part number against your saw's model and serial plate or the manufacturer's parts lookup before ordering, since parts can change between production runs. More bar and saw parts live in chainsaw parts.
