How does the construction improve performance and longevity?

OCPTY uses a steel billet pulley and attention to dynamic balance to reduce vibration and belt wear, which helps maintain consistent blade speeds under load. The design also allows serviceability of bearings through retaining rings, reducing future replacement cost and downtime.

• Steel billet pulley reduces abrasive wear on belts compared with stamped alternatives.
• Rotor balancing lowers energy loss and improves initial torque for quicker blade engagement.
• Retaining-ring pulley assembly enables bearing replacement without replacing the whole unit.

How do I confirm this is the right replacement for my machine?

Match the clutch’s physical and electrical specs to your original part number, shaft diameter and pulley OD. If you have the OEM number or a cross-reference from your mower’s parts manual, compare it to the listed replacement codes to confirm compatibility.

• Check your mower parts manual for OEM 117-7468 or any listed cross-reference numbers (e.g., 105-3462, 104-3334, AM119683).
• Measure your shaft diameter (1") and pulley outer diameter (5.375") to verify fitment.
• Confirm rotation direction is CCW and that the rated torque fits your application.
