If bearing replacement is required, remove the out
board bearing retaining ring (20). Use a bearing
puller to remove the bearings from the shaft.
Pump Casing and Transition Chamber Removal
(Ultra Mate Second Stage Model Only)
(Figure 3)
The removal method for the Ultra Mate pump cas
ing (1) depends on the configuration of the casing
discharge port. If the discharge port is in a vertical
position, install two eye hooks in opposing holes in
the discharge flange. Use a suitable sling and hoist
to remove the casing.
If the discharge port is in a horizontal position, fab
ricate a lifting device as shown in Figure 7 and
screw it into the hole for the pipe plug (4).
Make
certain
that the threaded end of the tool fully en
gages the threads in the casing. Use a suitable
sling and hoist to remove the casing.

LIFTING EYE
Figure 7. Casing Removal Tool
Do not attempt to lift the complete pump
unit using the lifting device. It is de
signed to facilitate removal or installa
tion of individual components only. Ad
ditional weight may result in damage to
the pump or failure of the lifting device.
Remove the hardware (7 and 21) securing the
pump casing to the transition chamber. Separate
the pump casing and O‐ring (22) from the transi
tion chamber.
If the transition chamber requires removal from the
Ultra V first stage pump, support the chamber us
ing a suitable hoist and sling. See Figure 1 and re
move the mounting hardware (8 and 9). Use the
hoist and sling to remove the transition chamber.
Remove the gasket (7).
Pump Casing and Transition Chamber Installa
tion (Ultra Mate Second Stage Model Only)
(Figure 1)
Apply `Permatex Aviation No. 3 Form‐A‐Gasket' to
the mating surfaces and install a new gasket (7).
Using the hoist and sling, position the transition
chamber on top of the first stage pump casing. Se
cure the transition chamber with the hardware (8
and 9). Remove the sling from the transition cham
ber.
(Figure 3)
Lubricate a new O‐ring (22) with a generous
amount of grease and install it over the shoulder on
the transition chamber (5). Using the same lifting
method as used for disassembly, position the
pump casing (1) over the transition chamber
shoulder and secure it with the previously removed
hardware (7 and 21). Remove the sling and, if
used, the lifting device from the pump casing and
reinstall the pipe plug (4).
Shaft and Bearing Reassembly and Installation
(Figure 4)
Clean the bearing housing, shaft and all compo
nent parts (except the bearings) with a soft cloth
soaked in cleaning solvent. Inspect the parts for
wear or damage 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.
