MP1 standard procedures and pump removal
Before working on the pump, thoroughly clean the outside. If the pump has an auxiliary pump attached,
remove both pumps as a single unit. Tag and cap all hydraulic lines as they are disconnected, and plug all
open ports to ensure that dirt and contamination do not get into the system.
Contamination can damage internal components and void the manufacturer's warranty.
Take precautions to ensure system cleanliness when removing and installing system lines.
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. As hydraulic lines are
disconnected, plug each open port, to ensure that dirt and contamination do not get into the pump.
3. Remove the pump and its auxiliary pump (if applicable) as a single unit.
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. Flush the system lines
and fill the reservoir with the correct, filtered hydraulic fluid.
8. Fill the pump with clean, filtered hydraulic fluid.
9. Attach the pump to the prime mover. Torque mounting screws according to the manufacturers
recommendation.
10. Replace all hydraulic lines. Ensure the charge inlet line is filled with fluid.
EDC Control
MP1 EDC control removal
Follow the instructions for safe removal of the EDC control.
1. Using a 5 mm internal hex wrench, remove the six cap screws (D250).
2. Remove the control module and gasket (D150). Discard the gasket.
3. If necessary, remove orifices (F00A and F00B) using a 3 mm internal hex wrench. Tag and number
them for re-installation.
