PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and de­
cals attached to the pump.
This pump requires little service due to its rugged,
minimum‐maintenance design. However, if it be­
comes necessary to inspect or replace the wearing
parts, follow these instructions which are keyed to
the sectional views (see Figures 1 through 7) and
the accompanying parts lists.
This manual will alert personnel to known proce­
dures which require special attention, to those
which could damage equipment, and to those
which could be dangerous to personnel. However,
this manual cannot possibly anticipate and provide
detailed precautions for every situation that might
occur during maintenance of the unit. Therefore, it
is the responsibility of the owner/maintenance per­
sonnel to ensure that only safe, established main­
tenance procedures are used, and that any proce­
dures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such prac­
tices.
Many service functions may be performed by
draining the pump and removing the back cover
assembly. If major repair is required, the piping
and/or engine must be disconnected. The follow­
ing instructions assume complete disassembly is
required.
Before attempting to service the pump, disconnect
or lock out the power source and take precautions
to ensure that it will remain inoperative. Close all
valves in the suction and discharge lines.
No instructions for removal and/or disassembly of
the enclosure or its components are provided in
this manual. If removal of the enclosure is required
for pump service, be sure to use safe shop practic­
es so as not to endanger personnel, and use cau­
tion to prevent damage to the enclosure.
For engine disassembly and repair, consult the lit­
erature supplied with the engine, or contact your
local engine representative.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man­
ual.
2. Switch off the engine ignition and
disconnect the positive battery
cable to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau­
tiously.
7. Drain the pump.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam­
age to equipment.
Back Cover And Wear Plate Removal
(Figure 4)
The wear plate (13) is easily accessible and may be
serviced by removing the back cover assembly
(16). Before attempting to service the pump, open
the ball valve (77, Figure 3) and drain the pump.
Close the valve after draining is complete.
Remove the back cover nuts (21) and pry the back
cover and assembled wear plate from the pump
casing (1).
NOTE
An alternate method of removing the back cover
from the pump casing is to remove the back cover
nuts (21) and two diagonally opposing locking col­
lars (17). Install two 1/2-16 UNC x 2 inch long
screws in the tapped holes in the back cover and
