Standard Procedures at Removing Pump
Before working on the pump, thoroughly clean the outside. If the pump has an auxiliary pump attached,
remove both pumps as a single unit.
1. With the prime mover off, thoroughly clean all dirt and grime from the outside of the pump.
2. Tag, disconnect, and cap each hydraulic line connected to the pump.
3. As hydraulic lines are disconnected, plug each open port, to ensure that dirt and contamination do
not get into the pump.
Be careful, do not damage solenoids and electrical connections when using straps or chains to
support the pump.
4. Ensure the work surface and surrounding area are clean and free of contaminants such as dirt and
grime.
5. Inspect the system for contamination.
6. Look at the hydraulic fluid for signs of system contamination, oil discoloration, foam in the oil, sludge,
or metal particles.
7. Before replacing the pump, replace all filters and drain the hydraulic system.
8. Flush the system lines and fill the reservoir with the correct, filtered hydraulic fluid.
9. Fill the pump with clean, filtered hydraulic fluid.
10. Attach the pump to the prime mover and torque mounting screws according to the manufacturers
recommendation.
11. Replace all hydraulic lines.
12. Ensure the charge inlet line is filled with fluid.
