Pump Disassembly
Remove the discharge piping. Remove the hard­
ware (104, 105 and 106) securing the discharge
spool flange (4) and flange gasket (7) to the pump
casing (1).
Remove the hardware (29, 55 and 56) securing the
bottle oiler bracket to the intermediate (15). Inspect
the bottle oiler (32) for cracks or leaks.
Use a suitable hoist and sling to support the pump
casing, and remove the remaining hardware (55
and 56). Separate the casing from the intermediate
assembly.
Remove the seal plate O‐ring (10) and inspect it for
damage.
To separate the rotating assembly from the power
source, use the eye bolt previously installed to sup­
port the intermediate (15). Remove the mounting
hardware and separate the rotating assembly from
the power source. Tie and tag any shims used un­
der the mounting foot. Remove the shaft key (34).
Separate the seal plate (57) from the intermediate
by removing the capscrews (11). Press the oil seal
(6) from the seal plate and inspect it for wear or
damage.
Separate the intermediate from the pedestal body
(47) by removing the hardware (49 and 50). Before
opening the pedestal cavity, remove the bottle oiler
and nipple (36 and 37) and drain the lubricant from
the pedestal by removing the pedestal drain plug
(43). Clean and reinstall the plug.
Shaft and Bearing Removal and Disassembly
When the pump is properly operated and main­
tained, the pedestal should not require disassem­
bly. 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‐
equipped shop by qualified personnel.
Remove the hardware (21 and 22) securing the
bearing housing (20) to the pedestal (47). Remove
the bearing shim set (41); tie and tag the shims or
measure and record their thickness for ease of
reassembly.
Remove the slinger ring (16) from the impeller shaft
(35).
Place a block of wood against the impeller end of
the shaft and tap the shaft, assembled bearings
and bearing housing (17, 19 and 20) from the ped­
estal bore. Be careful not to damage the shaft.
Remove the bearing housing O‐ring (42) from the
bearing housing.
Press the oil seal (8) from the pedestal body. In­
spect it for wear or damage.
Remove the hardware (23 and 24) securing the
bearing housing cap (25) to the bearing housing.
Pull the bearing cap and the bearing cap gasket
set (40) from the bearing housing.
Press the oil seal (30) from the bearing cap.
Apply heat to the outside of the bearing housing
(20) and press the heated bearing housing off the
outboard bearings (19 and 19A) and remove it
from the shaft.
After removing the shaft and bearings, clean and
inspect the bearings in place as follows.
To prevent damage during removal from
the shaft, it is recommended that bearings
be cleaned and inspected in place. It is
strongly recommended that the bearings
be replaced any time the shaft and bear­
ings are removed.
Clean the pedestal, bearing housing, shaft and all
component parts (except the bearings) with a soft
cloth soaked in cleaning solvent. Inspect the parts
for wear or damage and replace as necessary.
