Gorman-Rupp Pumps T6A3-B /F,/FM - Manual (Page 38)

OM-01046 T SERIES
MAINTENANCE & REPAIR PAGE E - 15
Be sure the pump and power source have been
properly lubricated, see LUBRICATION.
Remove the fill cover assembly (36) and fill the
pump casing with clean liquid. Reinstall the fill
cover and tighten it. Refer to OPERATION, Section
C, before putting the pump back into service.
LUBRICATION
Seal Assembly
(Figure 2)
Before starting the pump, remove the vented plug
(8) and fill the seal cavity with approximately 40
ounces (1,4 liters) of SAE No. 30 non‐detergent oil,
or to a level just below the tapped vented plug hole.
Clean and reinstall the vented plug. Maintain the oil
at this level.
Bearings
(Figure 2)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu­
larly through the sight gauge (24)
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 (9). Do not over‐lubricate.
Over‐lubrication can cause the bearings to over‐
heat, resulting in premature bearing failure.
NOTE
The white reflector in the sight gauge must be posi­
tioned horizontally to provide proper drainage.
Under normal conditions, drain the bearing hous­
ing once each year and refill with approximately 32
ounces (1 liter) clean oil. Change the oil more fre­
quently if the pump is operated continuously or in­
stalled 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.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
