Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with your equipment.
• Follow the equipment manual for detailed installation instructions.
• Apply medium-strength (blue) thread locker to threads and torque to 15–25 ft-lb (20–34 N•m).
• Ensure diaphragm lips face toward the center.
• Apply anti-seize lubricant liberally on drive shaft assembly surfaces.
• Install drive shaft assembly with groove facing up.
