ing, and remove the remaining hardware (29 and
65). Separate the casing from the pedestal (2).

Remove the seal plate O‐ring (22).

Separate the seal plate (8) from the pedestal by re­
moving the hardware (48 and 49). Remove the seal
plate O‐ring (9).

To separate the pedestal from the engine, remove
the hardware (15, 16, 29, 30 and 35, Figure E-1)
securing the coupling guard assembly (8, Figure
E-1) and remove the guard. Remove the separate
the halves of the coupling (33, Figure E-1) and re­
move the half from the impeller shaft (3). Remove
the drive key (62).

Install a lifting eye (not supplied) in the 3/8-18 NPT
tapped hole in the top of the pedestal. Be sure the
eye is fully engaged before attaching a hoist. Re­
move the mounting hardware (36, 37 and 38, Fig­
ure E-1) and separate the pedestal from the base.
Tie and tag any shims used under the mounting
foot.

Shaft and Bearing Removal and Disassembly

(Figure E‐3)

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.

Before opening the pedestal, drain the lubricant
from the pedestal by removing the drain plug (49).
Clean and reinstall the plug.

Remove the hardware (51 and 52) securing the
bearing cover (6) to the pedestal. Remove the
wave washer (38) and O‐ring (63). Inspect the oil
seal (7) and, if replacement is required, press it
from the bearing cover.

Place a block of wood against the impeller end of
the shaft (3) and tap the shaft and assembled bear­
ings (4 and 5) from the pedestal bore. Be careful
not to damage the shaft.

Inspect the oil seal (7A) 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.

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.

Clean the bearings thoroughly in fresh cleaning
solvent. Dry the bearings with filtered compressed
air and coat with light oil.

Bearings must be kept free of all dirt and
foreign material. Failure to do so will great­
ly shorten bearing life. Do not spin dry
bearings. This may scratch the balls or
races and cause premature bearing fail­
ure.

Rotate the bearings by hand to check for rough­
ness or binding and inspect the bearing balls. If ro­
