made during pump removal to properly orientate tee fit-
ting. Install suction dampener (with new O--ring) and ho-
sebarb (with new seal) to tee fitting.
IMPORTANT: If pump drive coupler components
were disassembled, make sure that pump hub
flanges and drive coupler are installed at right
1
angles (90 degrees) to each other (Fig. 10).

1. Drive coupler 2. Pump hub
ing bracket. Leave fasteners loose.
7. Place coupling spacers into rubber coupling. Install
cap screws, flat washers and lock nuts to secure rubber
couplings to pump hub. Make sure that cap screw
threads extend fully through lock nut.
IMPORTANT: Before securing spray pump to
mounting bracket, make sure that the pump shaft,
coupler assembly and electric clutch are properly
aligned. There should not be distortion of the rubber
couplings. Failure to properly align the pump may
result in coupler failure. The spray pump alignment
fixture (see Special Tools in this chapter) can be
used to properly locate pump mounting bracket to
machine frame and ensure coupler alignment.
8. Position pump on mounting bracket so that rubber
couplings are not distorted. Secure pump to mounting
bracket by tightening flange head screws and flange
nuts.
9. Apply Loctite #242 (or equivalent) to threads of pump
hub set screws. Install set screws into pump hub to se-
cure hub to pump shaft.
