necessary and keep personnel away

Use
Only Genuine Gorman-Rupp
re
placement parts. Failure to do so may cre
ate a hazard and damage the pump or di
minish optimal pump performance. Any
such hazard, damage or diminished per
formance is not covered by the warranty.
Back Cover And Wear Plate Removal
(Figure 4)
The wear plate (11) is easily accessible and may be
serviced by removing the back cover assembly
(13). Before attempting to service the pump, re
move the pump casing drain plug (10) and drain
the pump. Clean and reinstall the drain plug.
Remove the back cover nuts (19) 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 (19) and two diagonally opposing locking col
lars (17). Install two 1/2-13 UNC x 2 inch long
screws in the tapped holes in the back cover and
use them to press the back cover out of the pump
casing.
Inspect the wear plate and replace it if badly scored
or worn. To remove the wear plate, disengage the
hardware (15 and 30).
Inspect the back cover and wear plate O‐rings (6
and 12) and replace it if damaged or worn.
Suction Check Valve Removal
(Figure 4)
If the check valve assembly (24) is to be serviced,
remove the check valve pin (22), reach through the
back cover opening and pull the complete assem
bly from the suction flange (21).
NOTE
Further disassembly of the check valve is not re
quired since it must be replaced as a complete unit.
Individual parts are not sold separately.
Separating Intermediate And Drive Assembly
From Engine
(Figure 6)
Further disassembly requires separating the pump
end and drive assembly from the engine. Install a
standard 5/8‐11 UNC lifting eye in the tapped hole
in the top of the pump casing.
Be sure
to screw the
eye into the casing until fully engaged. Support the
pump using a suitable hoist and the lifting eye.
Do not attempt to lift the complete pump
unit using the lifting eye. It is designed
to facilitate removal or installation of in
dividual components only. Additional
weight may result in damage to the
pump or failure of the eye bolt.
Remove the hardware securing the pump casing
to the base.
Disengage the hardware (6 and 7) securing the
drive flange to the engine bellhousing, and remove
the guards (19, Figure 5). Separate the pump end
and drive assembly from the engine 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. Remove the shaft
key (23, Figure 5).
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.
