MAINTENANCE & REPAIR
PAGE E - 12
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.
NOTE
When appropriate recycling facilities are available,
the user should recycle components and fluids
when doing any routine maintenance / repairs and
also at the end of the pump’s useful life. All other
components and fluids shall be disposed of ac
cording to all applicable codes and regulations.
Back Cover and Wear Plate Removal
(Figure 3)
The wear plate (4) is easily accessible and may be
serviced by removing the back cover assembly (5).
Before attempting to service the pump, open the
ball valve (87, Figure 2) and drain the pump. Close
the valve after draining is complete.
Remove the back cover nuts (21) 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 (21) and two diagonally opposing locking col
lars (17). Install two 1/2-16 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 (11 and 12).
Inspect the back cover and wear plate O‐rings (10
and 13) and replace them if damaged or worn.
Suction Check Valve Removal
(Figure 3)
If the check valve assembly (32) is to be serviced,
remove the check valve pin (24), reach through the
back cover opening and pull the complete assem
bly from the suction flange (23).
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 Coupling
Assembly From Engine
(Figure 5)
Further disassembly requires separating the pump
end and drive assembly from the engine. Remove
the hardware securing the check valve/air release
valve assembly (33, Figure 3) to the pump casing.
Disengage and remove any additional compo
nents necessary for the removal of the pump end.
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 (7 and 8, Figure 3) secur
ing the drive flange to the engine bellhousing, and
remove the guards (26, Figure 4). Separate the
pump end and drive assembly from the engine by
pulling the pump end straight away from the en
gine.
As the assemblies separate, the flexible portion of
the coupling assembly (2) will remain on the shaft.
