LUBRICATION
Plunger Rod Assembly
(Figure 2)
The rod end should be lubricated thor-
oughly after each 8 hours of operation.
Failure to do so may cause the rod end
bearing to overheat and fail.
Before attempting to lubricate the plunger rod as-
sembly, rotate the eccentric cam until the upper
grease fitting (5) can be accessed through the
slotted hole in the eccentric guard (13, Figure 1).
Use a grease gun to apply No. 2 lithium base
grease to the upper lubrication fitting until grease
escapes from the eccentric cap. Lubricate the low-
er fitting (10) until grease escapes from the top of
the upper diaphragm plate inside the spring.
Gear Reducer
(Figure 1)
The gear reducer used on this unit is lubricated for
life from the manufacturer. No additional lubrica-
tion is required. If the gear reducer has been disas-
sembled for maintenance, follow the lubrication in-
structions provided by the gear reducer manufac-
turer for the recommended type and quantity of lu-
bricant.
