To install the tool, remove the air vent (8, Figure 11, Page 23) from the bearing
housing, and screw the longest length of pipe into the vent whole until fully
engaged. Install the tee, and screw the handles into the tee. Use caution when
lifting the rotating assembly to avoid injury to personnel or damage to the
assembly.
Remove the bearing housing and seal plate O-rings (9 and 4).
Impeller Removal
(Figure 11, Page 23)
With the rotating assembly removed from the pump casing, unscrew the impeller from
the shaft. Use caution when unscrewing the impeller; tension on the shaft seal spring
will be released as the impeller is removed. Inspect the impeller and replace if cracked
or badly worn.
Remove the impeller adjusting shims tie and tag the shims, or measure and record
their thickness for ease of reassembly.
Seal Removal
(Figure 11, Page 23)
Slide the integral shaft sleeve and rotating portion of the seal off the shaft as unit.
Use a pair of stiff wires with hooked ends to remove the stationary element and seat.
An alternative 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 removed.
Remove the shaft sleeve O-ring.
If no further disassembly is required, refer to seal installation.
Shaft and Bearing Removal and Disassembly
(Figure 11, Page 23)
When the pump is properly operated and maintenance, the bearing housing should not
require disassembly. Disassemble the shaft and bearings only when there is evidence
of wear or damage.
