How to Remove a Craftsman Sim-Pull Trimmer Clutch

The clutch on a Craftsman Sim-Pull trimmer connects the crankshaft to the driveshaft, allowing the head to spin and the trimmer to cut through weeds. Rotating constantly inside the engine, the clutch will undergo wear and gradually thin. When the clutch thins too much, it will no longer press onto the driveshaft and turn the head. The operator will need to remove the clutch to make any repairs to the clutch assembly or the internal engine.
