The GRACO 164231 is a connecting rod, typically made from durable metal, designed to link components within GRACO pumps such as the 50:1 Fire-Ball 425 series. Its primary function is to transmit motion between the air motor and the pump assembly, ensuring reliable operation of the equipment.

Key Features:

• Connecting Rod
• 19-13/32” (493 mm) long (model 205395 in some manuals, but commonly referenced as 164231 in parts lists)
• Compatible with GRACO 50:1 Fire-Ball 425 pumps and similar models
• Precision-machined for reliable motion transfer
• Designed for durability and long service life
• Critical for maintaining pump performance and safety

Applications:
Used in GRACO air-operated reciprocating pumps for transferring fluids in industrial lubrication, maintenance, and fluid handling applications.

Installation Notes:

• Using genuine GRACO connecting rods ensures proper fit, function, and safety of the pump assembly. Non-genuine parts may compromise performance and equipment longevity.
• Ensure all components are clean and free of debris before installation
• Follow torque specifications and assembly procedures as outlined in the GRACO manual
• Inspect the rod for wear or damage before installation and replace if necessary
• Use appropriate tools to avoid damaging the rod or surrounding components
• Regularly inspect the connecting rod for signs of wear, corrosion, or fatigue
• Lubricate as recommended by GRACO
• Replace the rod if it shows any deformation or excessive wear
