Product Description

The ECHO a556000481 is a clutch drum designed as a direct replacement component for ECHO outdoor power equipment. The clutch drum is a core part of the centrifugal clutch assembly, transferring rotational power from the engine to the cutting attachment or tool head when the engine reaches the engagement RPM. Licensed technicians and experienced small-engine mechanics typically service this component during routine drivetrain maintenance or when clutch slippage, noise, or wear is detected.

This clutch drum is suited for use in ECHO handheld outdoor power equipment that utilizes a centrifugal clutch system. Typical applications include trimmers, brushcutters, and similar ECHO power tools where the clutch assembly connects the engine output shaft to the working attachment. Install this part when the drum shows visible wear grooves, scoring, or heat discoloration that indicates it has reached the end of its service life.
