NOTE
If the gearbox is rotated out of the standard posi-
tion, the oil fill and drain plugs must be relocated.
The magnetic drain plug (53) must be relocated to
the lowest port, and the oil vent and elbow (12 and
13) must be relocated to the highest port. Consult
the factory for correct positioning of the fill plug to
provide for proper lubrication of the gearbox.
Under normal conditions, drain the gearbox once
each year. Add 2 ounces (59 ml) of Dow Corning
‘Molykote
r M Gear Guard’, then fill with approxi-
mately 23 ounces (680 ml) of SAE No. 90 non-det-
ergent gear 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 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.
