16. LUBRICATION
Seal Assembly
(Figure 11, Page 23)
Before starting the pump, remove the vented plug (8) and fill the seal cavity with
approximately 0,6 litres 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 11, Page 23)
The bearing housing was fully lubricated when shipped from the factory. Check the oil
level regularly through the sight gauge. When lubrication is required, 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 overheat, resulting in premature bearing failure.
NOTE:
The white reflector in the sight gauge must be positioned horizontally to
provide proper drainage
.
Under normal conditions, drain the bearing housing once each year and refill with
approximately 0,8 litre clean oil. Change the oil more frequently if the pump is operated
continuously or installed in an environment with rapid temperature change.
Monitor the condition of the bearing lubricant regularly for evidence of rust
or moisture condensation. This is especially important in areas where
variable and cold temperatures are common.
CAUTION!
For cold weather operation, consult the factory or a lubricant supplier for the
recommended grade of oil.
