Figure 4. Rotating Assembly Removal
Impeller Removal
(Figure 2)
Unscrew the impeller (1) in a counterclockwise di-
rection when facing the impeller. Use caution when
unscrewing the impeller; tension on the shaft seal
spring will be released as the impeller is removed.
Remove the impeller adjusting shims (10). Tie and
tag the shims or measure and record their thick-
ness for ease of reassembly.
Seal Removal
(Figure 2)
Slide the integral shaft sleeve and rotating portion
of the seal off the shaft as a unit.
Use a pair of stiff wires with hooked ends to remove
the stationary element and seat.
An alternate method of removing the stationary
seal components is to remove the hardware (25
and 26) and separate the seal plate (3) and gasket
(5) from the bearing housing (6). Position the seal
plate on a flat surface with the impeller side down.
Use a wooden dowel or other suitable tool to press
on the back side of the stationary seat until the
seat, O-rings and stationary element can be re-
moved.
Remove the shaft sleeve O-ring (24).
If no further disassembly is required, refer to
Seal

Shaft and Bearing Removal and Disassembly
(Figure 2)
When the pump is properly operated and main-
tained, the bearing housing should not require dis-
assembly. Disassemble the shaft and bearings
only
when there is evidence of wear or damage.
Shaft and bearing disassembly in the field
is not recommended. These operations
should be performed only in a properly-e-
quipped shop by qualified personnel.
Remove the bearing housing O-ring (30).
Remove the bearing housing drain plug (21A) and
drain the lubricant. Clean and reinstall the drain
plug.
Disengage the hardware (13 and 14) and slide the
bearing cap (15), O-ring (22) and oil seal (9) off the
shaft. Remove the O-ring, and press the oil seal
from the bearing cap.
Place a block of wood against the impeller end of
the shaft and tap the shaft and assembled bear-
ings (7 and 23) from the bearing housing.
After removing the shaft and bearings, clean and
inspect the bearings
in place
as follows.
