MAINTENANCE & REPAIR PAGE E - 6
Most cleaning solvents are toxic and
flammable. Use them only in a well ven­
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain­
ers.
If no further disassembly is required, see Seal
Reassembly and Installation.
Pump Disassembly
Remove the discharge piping. If disassembly is re­
quired, remove the hardware (15, 16 and 17) se­
curing the reducer (18) and flange gasket (20) to
the pump casing (1).
Remove the hardware (38, 54 and 55) securing the
bottle oiler bracket (39) to the pedestal (51). Use a
suitable hoist and sling to support the pump cas­
ing, and remove the remaining hardware (54 and
55). Separate the casing from the pedestal assem­
bly.
Remove the seal plate O‐ring (22).
Separate the seal plate (56) from the pedestal by
removing the hardware (24 and 25). Remove the
seal plate O‐ring (53).
Shaft and Bearing Removal and Disassembly
To separate the pedestal (51) from the power
source, install a lifting eye (not supplied) in the
3/8-18 NPT tapped hole in the pedestal. Be sure
the eye is fully engaged before attaching a hoist.
Remove the mounting hardware and separate the
pedestal from the power source. Tie and tag any
shims used under the mounting foot. Remove the
shaft key (43).
Do not attempt to lift the complete pump
unit using the lifting eye. It is designed
to facilitate removal or installation of in­
dividual components only. Additional
weight may result in damage to the
pump or failure of the eye bolt.
Before opening the pedestal, drain the lubricant
from the pedestal by removing the drain plug (50).
Clean and reinstall the plug.
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 (28 and 29) securing the
bearing cover (47) to the pedestal. Remove the
wave washer (46) and O‐ring (48). Inspect the oil
seal (42) and, if replacement is required, press it
from the bearing cover.
Place a block of wood against the impeller end of
the shaft (44) and tap the shaft and assembled
bearings (45 and 52) from the pedestal bore. Be
careful not to damage the shaft.
Inspect the oil seal (23) and, if replacement is re­
quired, press it from the pedestal.
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, shaft and all component parts
(except the bearings) with a soft cloth soaked in
cleaning solvent. Inspect the parts for wear or dam­
age and replace as necessary.
