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 ).
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 , item 1).
19. Check that the bearings (Figure 11-8 , item 10) are properly seated on the
finger box and install the finger box cover using the four screws, washers
and spring washers (Figure 11-8 , items 22, 14 and 25). Before
tightening these screws, rotate the motor coupling by hand to ensure
smooth rotation of the motor shaft and the encoder.
20. Tighten the screws to 6 kgf-cm (5.2 in-lb).
21. Install the motor holding plate onto the safety/slide clamp assembly.
Tighten the two screws (Figure 11-9 , item 30) to 6 kgf-cm (5.2 in-lb).
22. Apply a trace of Red Glpt Insulation Varnish to the set screws
(Figure 11-8 , item 27).
23. Place a 0.3 mm, flat-feeler gauge between the motor bottom surface and
the motor end plate.
Q If the flat-feeler gauge can be inserted and the gap is not wider than
0.3mm, proceed to the next step.
Q If the flat-feeler gauge cannot be inserted or the gap is wider than
0.3mm, loosen the set screws (Figure 11-8 , item 27) to move the
motor. Ensure that the edge of the flat-feeler gauge is touching the
side of the motor shaft. Press the motor against the plate and tighten
the set screws to 5 kgf-cm (4.3 in-lbs).
Note: When the set screws have been properly tightened, the screw heads are
recessed in the motor coupling and the screw ends are in contact with the flat
surfaces of the finger shaft.
24. Install the springs removed in step 6, and remove the flat-feeler gauge.
25. Install pump head assembly into case in accordance with “Replacement
of Pump Head Assembly” on page 8-12.
26. Perform the Operational Checkout procedures in Chapter 10,
“Operational Checkout”.
