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.
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-
al which could cause illness through di-
rect exposure or emitted fumes. Wear
adequate protective clothing when
working on the pump or piping.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. The bail is intended
for use in lifting the pump assembly
only. Suction and discharge hoses and
piping must be removed from the pump
before lifting. If chains or cables are
used to lift pump components, make
certain that they are positioned so as
