When to Choose This Kit
- Sprayer struggles to reach/hold working pressure despite good packings and check balls

- Pulsation at the gun with otherwise healthy filters, tips, and hose
Install Tips (Service-Friendly)
- Depressurize, flush, and lock out power/fuel per manual
- Follow the specific pump assembly diagram for your model/serial
- Lubricate seals per instructions; observe stack orientation
- Torque fasteners to specification and verify alignment
- Prime, test at low pressure, then verify performance at working pressure
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.
