Turn the inner threaded adjustment rod hex nuts (415A) until in place against the inner surfaces of
the outboard bearing end cover (109) and adjustment plate (234F) ears.
6.4.3 Assembly of other power end configurations
The assembly of other available power end configurations is very similar to that of the XHD oil lubricated
power end. All of the major pieces of the power end (bearing cartridge, end covers, bearings, etc.) are
designed for use with all options so only a few components will change regardless of the type of lubrica-
tion or isolators used.
The following subsections highlight the main differences in the assembly of power end configurations
other than the XHD oil lubricated power end.
Assemble the power end - XHD, grease lubrication, isolators
•
Regardless of the type of lubrication, the XHD power end uses labyrinth seals as bearing isolators.
Assembling the end covers and isolators will follow the same procedure as that of the XHD oil lubri-
cated version.
•
The only major difference between oil and grease lubricated power ends for the XHD is the use of
grease shields (346A), as shown on the figures below.

•
There are also grease fitting plugs (319H) and grease relief plugs (319Y) installed into the bearing
cartridge housing (228) used for purging and regreasing the grease lubricated XHD XL power end.
•
There will be no sight glass (319) or opposite sight glass (408N) on the grease lubricated power
end
6.4.4 Wet end assembly instructions
WARNING:
Before assembling the pump wet end to pedestal and power end, check to ensure that the ped-
estal is securely fastened to the foundation, baseplate or work surface (such as a workbench).
Also ensure that the bearing frame is securely assembled to the pedestal. Failure to do so
could result in injury or part(s) damage.
NOTICE:
When there is an expeller assembly supplied, the Wet End Assembly is not applicable.
In large part, steps taken to disassemble the wet end are used in reverse to reassemble the wet end to
the pedestal and bearing frame, and are outlined here. In addition, an entire assembled wet end can be
replaced on the XHD model as outlined in the section
6.4.5 Complete wet end connection - XHD on page
NOTICE: If you are reassembling an XHD Value Option model, skip the next section describing the com-
plete wet end connection and move onto
6.4.6 Wet end assembly instructions on page 119
. You can also
skip the wet end connection section if you have an XHD, have disassembled the wet end piece-by-piece,
and do not have a complete wet end to assemble to the pedestal and bearing frame.
