Frequently Asked Questions

Match the pump assembly and cylinder callout in your parts manual by model/serial. If your manual lists 243347 (or the cylinder kit supersession), it’s the correct choice.

The cylinder kit targets the cylinder/seal section only, reusing healthy hardware. A complete pump includes the entire displacement pump (rod, seats, balls, housing), costing more but replacing all wear areas at once.

Contents vary by revision. If your manual calls for a packing kit separately, order it together so all wear components are refreshed in one service session.

Many variants share the same pump family, but confirm by serial-based parts list. If your pump’s cylinder callout references 243347, you’re covered regardless of trim package.

Flush properly after use, keep filters/tips sized correctly, and avoid running dry. Periodically check for leaks and re-torque per the service manual after initial hours of use.
