Changing the Clutch Springs on an Echo String Trimmer

Place the trimmer on a flat workbench. Hold down the throttle trigger with one hand; follow the throttle cable up to the carburetor. Hold the throttle linkage in place with the other hand and release the throttle trigger; this will loosen the cable. Slide the cable out of the linkage. Pull off the spark plug wire from the spark plug located at the front of the engine.

Remove the four bolts from the bottom of the engine with the hex wrench and slide off the drive shaft, flip the engine upside down and slide off the flywheel cover exposing the clutch assembly. Place the punch close to the inside of the clutch and hit the punch with a hammer while turning the clutch assembly counterclockwise until it frees. Spin the clutch off the threaded shaft the rest of the way by hand.

Gently bend the clutch shoes until both the spring comes off. Install the new springs. Turn the clutch assembly back onto the threaded shaft until it is hand-tight. Put the punch on the inside of the clutch assembly and hit the punch with the hammer clockwise until tightened. Reinstall the flywheel cover, place the drive shaft back onto the bottom of the engine and install the four bolts. Place the throttle cable back into the throttle linkage on the carburetor.
