Frequently Asked Questions

Verify the pump assembly used in your sprayer. If that pump’s parts list calls the connecting rod 164444, it will fit. Some sprayers use different pump families with different rods.

It’s commonly used in Graco displacement pumps such as the Bulldog 5:1 series and other assemblies that explicitly specify 164444 as the connecting rod.

Follow the Graco service manual: stop the pump at bottom of stroke, align components, and apply specified torque. Inspect coupling and packings; misalignment accelerates wear.
