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 E‐1 through E‐3) and
the accompanying parts lists.
Before attempting to service the pump, shut down
the engine and remove the key to ensure that the
pump will remain inoperative. Close all valves in the
suction and discharge lines.
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. Shut down the engine and remove
the key 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.
Suction Check Valve Disassembly
(Figure E‐1)
Before attempting to service the pump, remove the
lowermost pipe plug (66, Figure E‐3) and drain the
pump. Clean and reinstall the drain plug.
(Figure E‐3)
To service the suction check valve assembly (22),
loosen the cover clamp screw (42) and remove the
cover plate clamp (41) securing the cover plate as­
sembly (40) to the suction elbow (19). Remove the
cover plate gasket (23) and replace as required.
Reach through the access opening and remove
the hardware and pivot caps securing the check
valve to the check valve body. Remove the check
valve through the access opening.
Inspect the check valve for wear or damage. If re­
placement is required, remove the flat washers
from the pivot arm. Tie and tag the washers for fu­
ture reference.
If the check valve body needs replaced, remove
the suction piping. See Figure 1 and remove the
hardware (4, 5 and 45) securing the adaptor flange
(46) to the suction elbow (19, Figure 3). Remove
the adaptor flange and gasket (3).
Remove the “Victaulic” coupling (39) and separate
the valve body from the suction elbow. Inspect the
rubber “Victaulic” gasket for damage and replace
as required.
If no further disassembly is required, see Suction
Check Valve Assembly.
Suction Elbow and Wear Plate Removal
(Figure E‐3)
Service to the wear plate (16), impeller (11) or seal
assembly (10), can be accomplished from either
side of the pump casing (1). The following instruc­
tions are based on service from the suction side of
the pump.
Install a 3/4-10 UNC-2B lifting eye (not supplied)
in the tapped hole located in the suction elbow. Be
sure the eye bolt is fully engaged before attaching
a hoist. Support the suction elbow using a suitable
hoist and sling. The hoist is used to support the
