Frequently Asked Questions

Match your unit’s pump assembly number to the confirmed list (204-287 or 215-873). If your pump number differs, check the parts list in your Graco manual or contact support with your model and serial number.

Excessive play in the pump linkage, irregular stroke, knocking noises, or failure to build pressure can indicate a worn or damaged connecting rod. Inspect for wear at the crank and piston interfaces.

It’s good practice to inspect related wear items (piston rod, pins, bushings/bearings, and fasteners). Replace any out-of-tolerance components and torque to spec per the Graco service manual.
