Removal of the Water Cascade
If your system is equipped with a water cascade system, remove
it before proceeding:
1. Loosen the socket head screws holding the water cascade
block on the stationary seat retainer and remove the plastic
hose.
2. Pull off the impeller/backplate assembly and place it on a
clean, flat surface with the impeller shaft facing up.
NOTE: If the assembly cannot be removed from the motor shaft
by hand, contact Waukesha Cherry-Burrell Customer Service.
3. Locate the shims on the motor shaft and remove them.
NOTE: Motor shaft shims may fall off the motor shaft or hang up
inside the deflector. Be sure to place all shims back on the
motor shaft.
CAUTION: Handle the impeller/backplate assembly with
care to prevent damage to the seal components.
4. Place the impeller assembly face down (on impeller vanes)
and remove the hex head screws (Figure 37, item V) from the
back of the seal assembly.
