valve body to the suction piping. Disconnect the
shoulder-type coupling (36) and separate the valve
body and check valve from the suction head. Sepa-
rate the check valve from the valve body as de-
scribed above.
Replace the cleanout cover gasket (3) before rein-
stalling the cover.
Suction Head And Wear Plate Removal
(Figure 3)
To remove the suction head, support it with a suit-
able hoist and sling and remove the hardware (27,
28, 29 and 30) securing it to the pump casing. Re-
move the suction head gasket (25).
If the wear plate (31) does not slide easily from the
casing bore, install capscrews (1/2-13 UNC X 1
inch long, not supplied) in the tapped holes in the
suction head and use a suitable puller to remove
the wear plate from the pump casing.
NOTE
An alternate method of removing the wear plate is to
position a wood or soft metal wedge between the
impeller vanes and the wear plate, and tap the
wedge with a hammer. Turn the impeller every 45
_,
repeating the process until the wear plate is
walked" out of the pump casing.
If the pump is to be completely disassembled, the
wear plate can also be easily removed after remov-
ing the rotating assembly (2). Use a suitably sized
piece of wood to tap the wear plate out of the casing
through the rotating assembly opening.
Separating Pump And Drive Assembly From
Engine
(Figure 3)
Further disassembly requires separating the pump
end and drive assembly from the engine. Remove
the discharge elbow and gasket (10 and 13) and fill
cover and gasket (64 and 67) from the pump cas-
ing. Loop a suitable chain or cable through the dis-
charge port and back out the priming port and at-
tach it to a hoist.
Make certain the chain or cable is posi-
tioned so that the pump will not be dam-
aged, and so that the load will be balanced.
(Figure 5)
Disengage the hardware (6 and 7) securing the
drive flange (14, Figure 2) to the engine bellhous-
ing, and remove the guards (35, Figure 4). Sepa-
rate the pump end and drive assembly from the en-
gine by pulling the pump end straight away from
the engine.
As the assemblies separate, the flexible portion of
the coupling assembly (3) will remain on the shaft.
To remove the coupling from the shaft, unscrew the
two allen head setscrews from the bushing (2).
Screw one of the setscrews into the puller hole on
the circumference of the bushing. As the coupling
and bushing separate, remove the bushing, and
slide the coupling off the shaft.
It is not necessary to remove the outer ring of the
coupling from the engine flywheel unless the cou-
pling must be replaced. To remove the ring, disen-
gage the hardware (4 and 5) securing it to the fly-
wheel.
Remove any leveling shims used under the casing
mounting feet. Tie and tag the shims for ease of
reassembly.
Move the pump end to a clean, well equipped shop
area for further disassembly.
Loosening Impeller
(Figure 4)
Before attempting to loosen the impeller, remove
the seal cavity drain plug (30A) and drain the lubri-
cant. This will prevent the oil from escaping as the
impeller is removed. Clean and reinstall the drain
plug.
With the pump end separated from the engine and
the suction head (32, Figure 3) removed, wedge a
block of wood between the vanes of the impeller
and the pump casing to prevent rotation.
If removed, install the shaft key (17) in the shaft
keyway. Install a lathe dog on the drive end of the
