MAINTENANCE & REPAIR
PAGE E - 25
replace this valve with a substitute which has not
been specified or provided by the Gorman‐Rupp
Company.
Periodically, the valve should be removed for in
spection and cleaning. When reinstalling the relief
valve, apply `Loctite Pipe Sealant With Teflon No.
592', or equivalent compound, on the relief valve
threads. Position the valve as shown in Figure 4
with the discharge port pointing down.
Final Pump Assembly
(Figure 1)
Be sure
the pump is secured to the base and en
gine. Be sure to install any guards used over the ro
tating members.
Do not operate the pump without
the
guards in place over the rotating parts.
Exposed rotating parts can catch cloth
ing, fingers, or tools, causing severe in
jury to personnel.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure
the pump and engine have been properly
lubricated, see
LUBRICATION
.
Remove the fill cover assembly (25, Figure 4) and
fill the pump casing with clean liquid. Reinstall the
fill cover and tighten it. Refer to
OPERATION
, Sec
tion C, before putting the pump back into service.
LUBRICATION
Seal Assembly
(Figure 5)
Before starting the pump, remove the vented plug
(10) and fill the seal cavity with SAE No. 30 non‐de
tergent oil to the middle of the sight gauge (14)
and
maintain it at the middle of the gauge. Clean and
reinstall the vented plug. Maintain the oil at this lev
el.
Bearings
(Figure 5)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu
larly through the sight gauge (14A)
and maintain it
at the middle of the gauge. When lubrication is re
quired, add SAE No. 30 non‐detergent
oil through
the hole for the air vent (11).
Do not
over‐lubricate.
Over‐lubrication can cause the bearings to over‐
heat, resulting in premature bearing failure.
Under normal conditions, drain the bearing hous
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operated con
tinuously or installed in an environment with rapid
temperature change.
Monitor the condition of the bearing lubri
cant regularly for evidence of rust or mois
ture condensation. This is especially im
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
Engine
Consult the literature supplied with the engine, or
contact your local engine representative.
