Apply No. 2 lithium base grease to the upper lubri
cation fitting (26) until grease escapes from the end
cap (27).

the upper diaphragm plate inside the spring.
Gearbox
(Figure 4)
The speed reducer was fully lubricated when
shipped from the factory. Change the oil in a new
gearbox at operating temperature after 100 hours
of operation or four weeks which ever comes first.
To drain the oil, remove the oil drain plug at the bot
tom of the gear housing cover and the vented plug
at the top of the gear housing cover. Flush the case
thoroughly with a light oil. Clean and reinstall the oil
drain plug.
To fill the speed reducer, remove the oil level plug in
the side of the gear housing cover, and add new oil
of the proper grade (see the following reference)
through the vented plug hole until it flows out the oil
level hole. Clean and reinstall the vented plug and
the oil level plug.
Under normal conditions, drain the gearbox every
500 hours of operation or every six months and re
fill with approximately 20 ounces (0,6 L) of SAE
20-30 non‐detergent oil. Change the oil more fre
quently if the pump if operated under severe condi
tions, 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.
