WARNING !
SECURE THE PEDESTAL AND PUMP HEAD ASSEMBLY TO AN
APPROPRIATE HOIST TO PREVENT POSSIBLE INJURY OR DAMAGE.
Note: On certain splined shaft assemblies you may need to remove a retaining ring
at the base of the pedestal, near the oil seal. (See Figure 6a-10: “Pedestal Mount
Pump Shaft Oil Seals (2), 40 / 5- FB-U and 80 FC-U Series” on page 106.)
3. Disassemble the pedestal from the pump head:
(See Figure 6a-10: “Pedestal Mount Pump Shaft Oil Seals (2), 40 / 5- FB-U
and 80 FC-U Series” on page 106.)
❑ For 40 FB-U - remove four (4) 9/16”-12 screws and sealing washers from
within the pump head.
❑ For 80 FC-U - remove four (4) 5/8”-11 screws from the pedestal flange.
4. Using an appropriate hoist for added support, slide the pump head and
