Rotary Ignition Coil Module

A faulty ignition coil often manifests as a chainsaw that runs for a few minutes and then dies once the engine heats up, or one that has no spark at the plug despite fresh fuel and a clean carburetor. If you have ruled out fuel delivery and compression issues, the ignition system is the next logical component to test.

Yes, this Rotary module is engineered as a direct aftermarket replacement. It is designed to match the mounting points and electrical specifications of the original Husqvarna components, allowing for a straightforward installation without modifications.

This module is compatible with several popular Husqvarna models, including the 61, 268, 45, 51, 55, 240, 245, 257, and 250-PS. We recommend cross-referencing your specific machine's OEM part number against the list provided to ensure a perfect match.

This unit replaces several OEM numbers, including 503-9014-01, 544-0184-01, 503-6202-03, 506-0272-07, 544018401, 587329601, 587329602, and 587329603. Always check your manual or the existing part for these specific numbers before purchasing.

You generally only need standard shop tools, such as a socket set or screwdriver, to access the coil and remove the old unit. However, you will need a feeler gauge to set the correct air gap between the new coil and the flywheel magnet during installation to ensure a strong spark.
