The clutches on Weed Eaters come attached to the front of the power head, just in front of the flywheel and starter assembly. These clutches act through centrifugal force to engage the drive shaft in the drive tub, which turns the cutting head. You need to remove the clutch whenever you want to work on the flywheel, starter assembly or clutch parts. Clutch parts tend to wear out after four to five seasons or sooner if not cared for properly.
Things You'll Need
- Fuel container
- Needle-nosed pliers
- T-25 Torx screwdriver
- Socket wrench
- 5/8-inch socket
- Dish soap
Open the gas tank on your Weed Eater and drain all contents into the fuel container. Pump the primer bulb twice to purge all fuel from the system. Move the ignition switch into the “STOP” position. Lift the rubber boot on top of the spark plug off the tip of the plug.
Disconnect the throttle cable’s Z-fitting from the carburetor’s throttle arm, which on the Weed Eater is located beneath the air filter, in the space before the engine. Use the needle-nosed pliers to squeeze the tabs while gently pulling away from the arm.
Unscrew the rear hand guard with the throttle control lever and ignition switch attached to it. Unplug the two lead wires from the ignition switch, using your fingers so you don’t damage the wires. Unscrew the four mounting screws holding the boom shaft to the front of the housing. Slide the shaft out and back to separate it from the engine.
Unhook the spark plug from the cylinder with the socket wrench and the 5/8-inch socket; remove the plug. Pull out about 10 inches of starter rope from the pulley. Feed slowly about 3 to 4 inches of rope into the cylinder hole. Feed it gently while feeling the position of the piston so you can block it.
Unscrew the clutch drum’s center bolt with the socket wrench and 5/8-inch socket. Turn the screw counterclockwise and slide the clutch drum off the stub. Unscrew the two clutch plates using the wrench. Slide the clutch plates off the stub.
Wash the clutch parts with a rag and inspect them for damage. Replace parts as necessary and install all components in the reverse order.
