Removal/Replacement Procedures Disassembly/Reassembly
Replacement of Pump Head Door Cover
1. Open the pump head door.
2. Remove five screws that secure the pump head door cover to the pump
head door (Figure 11-5 and Figure 11-10 , item 28). Do not remove the
screw affixing the metal plate in the recess at the bottom of the door
(Figure 11-5 and Figure 11-10 , item 27).
3. If clicking is heard during pump operation and is irritating, you may be
able to stop this by following the procedure below, otherwise proceed to
the next step:
3.1 Remove the seven screws (item 26 in Figure 11-5 or
Figure 11-10 ) from the outside of the door.
3.2 Remove one screw (item 27 in Figure 11-5 or Figure 11-10 )
from the inside of the door.
3.3 Note how the springs are currently installed to ensure they are
installed correctly later.
3.4 Remove the five springs (item 18 in Figure 11-5 or
Figure 11-10 ) and the back plate (item 17 in Figure 11-5 or
Figure 11-10 ).
3.5 Apply a very small quantity of silicon grease (part no. G-501)
to the four blue pads (item 20 in Figure 11-5 or Figure 11-10 )
located inside the back plate slot with a brush.
3.6 Ensure that the back plate is clean.
3.7 Ensure that the five springs are installed correctly.
3.8 Ensure that the safety clamp plate (item 15 in Figure 11-5 or
Figure 11-10 ) and any spacers are in place.
3.9 Align the notch in the back plate with the tongue in the door
and secure the back plate in place with the eight screws (items
26 and 27 in Figure 11-5 or Figure 11-10 ) removed previously.
Torque to 6 kg-cm (5.2 lbs.-in.)
3.10 Proceed to the next step.
Note: If this does not stop the clicking you need to check for the source in other
areas such as a loose motor coupling or a misaligned motor.
Perform this step carefully so as to avoid losing the springs held in place by the
screws you just removed.
