Frequently Asked Questions

It includes the core wear parts for the fluid section (packings, checks/valves, seats/rings, related hardware). Contents can vary by revision—refer to your model’s parts schematic for an exact contents list.

Verify your exact model and series (e.g., LineLazer IV 3900, V 3900, ES2000, V ES2000, FieldLazer R300) and cross-check the fluid section assembly in your parts manual. If unsure, share your model & serial for confirmation.

Expect low/unstable pressure, surging, hard or failed priming, inconsistent fan pattern, and possible packing leakage. Rebuilding restores seal integrity and check-valve performance.

Lubricate packings as specified, prime slowly with compatible fluid, check for leaks, and re-torque fasteners after initial run. Always follow the official service manual for torque specs and pressure testing.

If you’re comfortable with pump service and have the proper tools, it’s straightforward. Otherwise, use a qualified technician. Always relieve pressure, lockout power, and follow safety procedures.
