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 illustrations (see Figures 1 through 7) and the
corresponding Parts Lists. Maintenance and repair
instructions for the engine is covered separately in
the specific literature supplied by the manufactur
er.
Many pump service functions may be performed
without separating the pump end assembly from
the engine. However, the priming chamber assem
bly and discharge piping must be removed to ser
vice most pump components. The following in
structions assume complete disassembly of the
pump is required.
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.
Before attempting to service the pump, shut down
the engine and take precautions to ensure that it
will remain inoperative. Close all valves in the suc
tion and discharge lines and drain the pump cas
ing by removing the lowermost pipe plug (10, Fig
ure 4) from the pump casing. Clean and reinstall
the drain plug.
This manual will alert personnel to
known procedures which require spe
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel.
How
ever, this manual cannot possibly antici
pate and provide detailed instructions
and precautions for every situation that
might occur during maintenance of the
unit. Therefore, it is the responsibility of
the owner/maintenance personnel to
ensure that only safe, established main
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Shut down the engine and discon
nect 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 and make
sure it is cool before opening any
covers, plates, gauges, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau
tiously.
7. Drain the pump.
This pump is designed to handle materi
