Husqvarna T540XP Mark II Ignition Coil

A failing ignition coil often manifests as a chainsaw that refuses to start when hot, runs erratically, or loses power under load. If you have already ruled out fuel delivery issues and verified the spark plug is functional, the coil is the most likely culprit for these intermittent performance failures.

This ignition coil is specifically designed as a direct replacement for the T540XP Mark II. Because Husqvarna updates components across different production years, always verify your chainsaw's specific model number against the part number 587306804 to ensure a perfect fit.

You will need standard shop tools, typically including a screwdriver and a socket set to remove the chainsaw housing. It is also highly recommended to use a feeler gauge to set the correct air gap between the coil and the flywheel during installation, as this is critical for proper spark timing.

Performing routine maintenance or replacing wear-and-tear parts like an ignition coil generally does not void a manufacturer's warranty. However, if your machine is still under the original factory warranty period, it is always best to consult your local authorized service center first.

This ignition coil is engineered to match the precise timing and electrical output requirements of the Husqvarna T540XP Mark II engine. Using a part designed for your specific model ensures consistent combustion and prevents the timing issues that can sometimes occur with generic, one-size-fits-all replacements.
