Verify before ordering

• Measure the engine shaft diameter; it must be 3/4 in.
• Confirm the shaft length, keyway and retaining-bolt arrangement.
• Confirm #40/#41/#420 chain pitch and chain alignment.
• Check sprocket clearance and rotation before starting the engine.

Installation note: Disconnect the spark-plug lead before service. Align both sprockets, secure the clutch with the correct key and retaining hardware, set proper chain tension, and rotate the drivetrain by hand before operation. Do not use the vehicle if the chain binds or the clutch contacts nearby components.
