8. Remove two screws, washers and spring washers (Figure 11-8 or
Figure 11-13 , items 22, 14 and 25) securing the encoder cover
(Figure 11-8 or Figure 11-13 , item 16) and finger box cover to the
finger box. Do not lose the short nut bar (Figure 11-8 or Figure 11-13 ,
item 30).
9. Remove two screws, washers and spring washers (Figure 11-8 or
Figure 11-13 , items 22, 14 and 25) securing the finger box cover to the
finger box (item 15) above the motor coupling. Do not lose the long nut
bar (Figure 11-8 , item 31).
10. Remove the finger box cover.
Note: Slide the encoder cover toward the encoder to prevent it from sticking to the
encoder screw head.
11. Carefully lift the motor and remove motor and its associated assembly
from the pump head base plate. Take care not to deform the encoder or
damage the fingers. Keep the finger box and the fingers away from dirt
or dust.
12. Remove the motor holding plate (Figure 11-9 or Figure 11-14 , item 8)
from the motor shaft bottom and carefully place on the work surface.
13. Remove two set screws (Figure 11-8 or Figure 11-13 , item 27) closest
to the motor.
14. To install the motor, push motor shaft into motor coupling (Figure 11-8
or Figure 11-13 , item 8).
15. Install set screws (Figure 11-8 or Figure 11-13 , item 27). Do not tighten
them at this time.
16. Attach the spring retainer (Figure 11-8 or Figure 11-13 , item 2) to the
replacement motor, as necessary.
17. Place the motor holding plate (Figure 11-9 or Figure 11-14 , item 8)
onto the motor shaft bottom such that the plate sticks out of the motor
housing on the side with the motor wires (Figure 11-8 or Figure 11-13 ).
18. Install the motor and its associated assembly into the pump head base
plate with the following cautions:
18.1 The motor must be positioned such that the wires go out the
rear of the base plate (Figure 11-8 or Figure 11-13 ).
18.2 Be sure that the fingers are in the finger box and the motor
holding plate is properly installed in the groove of the safety/
slide clamp assembly (Figure 11-8 or Figure 11-13 , item 1).
