19. Install the two hold-down screws, washers, and
springs (10, 11, 25). Bottom the screws and check
the vertical travel of the retainer (A) against the
spring. If the shaft nut (28) and coupling housing
(58) are properly installed, the retainer should lift
0.12 to 0.19 in. (3.2 to 3.8 mm) before the springs
are solidly compressed.
20.
If the pump is mounted in an assembly stand
,
loosen the shaft holding tool. See Fig. 4.
Turn the bearing adjusting nut (35) two and a half
notches to the right to raise the impellers off the
bowls. Now turn the pump coupler (58) to be sure
the shaft (33) rotates freely. Check to see that the
slinger (40) is located approximately in the center
of the slinger chamber. See Fig. 6.
If the
pump is not mounted in an assembly
stand
, turn the bearing adjusting nut (35) up until
the shaft (only) rotates freely. Then raise it another
two and a half notches to raise the impellers off the
bowls. See Fig. 6.
21. Install the lockscrew (19) through the pump base
and into the hole in the adjusting nut (35) without
forcing it. Install the plug (27). If necessary, turn
the adjusting nut a little, in the same direction as
pump rotation, until the plug goes in easily. Tighten
the plug securely and attach the lockwire (26) and
crimp. See Figs. 5 and 6.
22. Install the gasket, slinger chamber cover, and
screws (20, 21, 3) on the front of the pump base.
23. Install the rubber coupling insert (6) and remount
the motor. Refer to Fig. 2, page 6.
24. Remove the shaft holding tool, if installed. Install
the plug (49) and gasket (50) (see the parts
drawing). Start the pump. Use the filter isolation
valves (Q) to control the pump flow to 50 psi (3.5
bar) until the lines are full, and then completely
open the valves. Circulate the paint until all air is
removed from the fluid lines. Close the check valve
(J) or isolation valves (Q). Note the maximum
pump pressure. The pressure should be steady. If
variations or pulsations are noted, the inlet flow to
the pump is restricted, due to either a clogged
screen or restricted plumbing. Correct the clogged
condition.
CAUTION
When checking the pump pressure,
do not
leave
the check valve (J) or isolation valves (Q) closed
for more than 10 seconds while the pump is operat-
ing to avoid overheating the pump and damaging
the seals and bearings.
