Frequently Asked Questions
The tie rod clamps and aligns the pump assembly—linking the displacement pump to the air motor/upper housing—so the pump runs true and maintains sealing force under pressure and vibration.
It’s best practice to replace in sets when rods are corroded, stretched, or damaged to maintain even clamping force and alignment. Always torque to the specification in your model’s service manual.
Match the part number 164722 in your unit’s parts list. Check the rod length (~111 mm shoulder-to-shoulder), shoulders, and threads against your serial-range manual before ordering.
