Echo Metal Flywheel & Key A409001250 PB-250LN ES-250 ES-252 Blower OEM New

Echo Metal Flywheel & Key A409001250 PB-250LN ES-250 ES-252 Blower OEM New.

Restore Factory Ignition Timing & Smooth Rotational Balance: Genuine Echo Flywheel & Key

Eliminate starter pull-cord kickback, violent backfiring, sheared timing keys, cracked cooling fins, and no-start ignition timing issues on your Echo handheld blower or vac. This Genuine Echo Factory OEM Metal Flywheel & Key Kit (Part Number A409001250) is the authentic die-cast aluminum balanced flywheel and woodruff key package engineered explicitly for Echo PB-250LN handheld blowers and ES-250 / ES-252 Shred 'N' Vac units across designated serial number ranges . Running a 2-stroke handheld machine with a sheared key, wallowed-out shaft taper, or chipped cooling fins destroys ignition timing, shakes the machine violently in the operator’s hand, and can snap the crankshaft.

Precision die-cast and dynamically balanced to Echo's strict Japanese engineering standards, this metal flywheel features a high-tolerance tapered center bore designed for rigid, zero-slip interference seating onto the crankshaft snout. It integrates cast-in rare-earth permanent magnets that induce a clean, hot spark across the ignition coil air gap at governed operating speeds ( $7,000+\text{ RPM}$ ). Heavy-duty turbine fan blades provide high-volume cooling airflow across the cylinder head fins to prevent engine overheating during long commercial leaf cleanups. The included genuine factory woodruff key ensures indexing and locking of engine timing.

This authentic factory replacement component is cataloged under Echo OEM Part Number A409001250 (A-409-001250 / Flywheel & Key, Metal, 250 Ser / Rotor Assembly Metal) .

Why This Genuine Echo A409001250 OEM Flywheel Kit is the Pro Standard:

100% Genuine Factory OEM Component: Precision-cast and dynamically balanced to exact Echo factory blueprints for vibration-free high-RPM operation.

Complete Assembly with Factory Woodruff Key: Includes both the matched metal flywheel and authentic steel indexing key for guaranteed timing alignment.

Precision-Machined Crankshaft Taper: Clean, ground internal taper locks solidly onto the crankshaft snout with proper clamping interference to prevent future key shearing.

High-Flux Cast-In Magnets: Ensures immediate primary coil voltage induction for fast, easy pull-starts and consistent ignition timing under load.

Aerodynamic Air-Cooling Fins: Cast cooling blades direct cooling air across cylinder fins, preventing heat soak and vapor lock during heavy summer use.
