Most Common Reason to Replace: The most common reason for replacing the flywheel is if the engine won’t turn. Additional symptoms include hard starting, no spark, misfiring, or visible damage to the flywheel fins, keyway, or magnets. A sheared flywheel key (caused by hitting a hard object) can also throw off ignition timing and require flywheel inspection or replacement.

Tools Required for Installation: A T25 Torx bit, spark plug wrench, clutch tool, rope, T20 Torx bit, and two flat-head screwdrivers are needed to replace this flywheel. A flywheel puller is also strongly recommended to safely remove the press-fit flywheel from the crankshaft taper.

Why Genuine OEM? Aftermarket flywheels can have imprecise magnet placement or incorrect keyway dimensions, throwing off ignition timing and causing hard starts, misfires, or engine damage. This authentic Husqvarna flywheel is manufactured to the exact magnetic pole geometry and crankshaft taper fit of the original, ensuring the ignition system fires at the correct timing every time.
