Removing the hydraulic rotary pump

Removes the hydraulic rotary pump from the dockable table.

Prerequisites

Procedure

  1. Raise the patient table to the full up position.
  2. Set the brake to keep the table stationary.
    Figure 1. Caster brake
  3. Lower the table lock safety bar to the locked position.
    Note: Lower the table so its weight is resting on the lock bar.

  4. To remove the table frame connector assembly , do the following:
    1. Remove the e-clip from the rod link on the right side of the table frame connector assembly, and slide the rod link off of the pin. Repeat this process on the left side of the assembly.

    2. Remove the bracket screws from the frame connector assembly and remove the bracket (see Figure 3).
    3. Detach the spring near the right rod link, and detach the matching spring near the left side rod link (see Figure 3).
    4. Detach the spring under the right cable track, and detach the matching spring under the left side cable track.

    5. Pull the entire assembly forward to reveal the rotary pump assembly below.

    Note: Before proceeding to the next step, first prepare the new hydraulic rotary pump for installation and place it within reach. Place absorbent towels underneath the work area.
  5. On the right side of the pump, disconnect the manifold nut from the connector fitting (see Figure 7).
    Note: Use a towel as plug to stop flow of fluid.
  6. Remove three brass screws from the lower front table base. After screw removal, the pump assembly hangs freely and should allow sufficient movement. Use care in holding the rotary pump, the brass plate, and the guide coupling in place because those components (as a unit) will fall straight down.

  7. Lower the pump assembly. Remove the plastic clamp from the transparent low-pressure hose and then remove the hose, quickly plugging the end of the hose with a thumb or a towel to minimize leaking.
