FIGURE 2 – CRANKCASE OIL REQUIREMENTS
LUBRICATION
- All power end working parts are
lubricated by the oil in the crankcase. Check oil level
frequently. Selection of oil is to be taken from the
recommendations given in FIGURE 2 and on the pump
data plate. Local conditions and practice may also
influence the selection. Essential additives are foam
and oxidation inhibitors. Oil is to be added as required
to maintain oil level near the top of the oil level
indicator on the side of the frame.
• Oil viscosity must not exceed 7000 SSU at start-up
and must be between 1500 SSU and 200 SSU
while operating, regardless of the oil temperature or
grade used. A crankcase heater and/or an oil heat
exchanger may be needed to meet these
requirements.

FIGURE 3 – LUBRICATION SCHEDULE
•
Failure to follow these lubrication requirements will
void the warranty.
•
Some operating conditions and/or oil brands
produce excessive oil foaming, even when the
specified GL-5 oils containing antifoaming
additives are used. Oil foaming can cause pump
damage, as oil bubbles will not lubricate moving
parts properly. If significant oil foaming occurs,
contact Gardner Denver Marketing or Service,
(217) 222-5400, for the current factory
recommended defoamant to be added to the
lubricating oil.
•
Oil must have antiwear, antifoaming, noncorrosive
and rust inhibiting additives.
Oil is constantly circulated through a renewable
element filter and then through a heat exchanger,
when one is used, by means of a rotary pump driven
from the main gear. Oil is discharged into an elevated
oil feed trough, from which it is conducted to jackshaft
and main bearings. Oil also flows from the trough to
lubricate the connecting rod bearings.
Operating temperatures of the oil should be kept below
200
o
F (93.3
o
C) to reduce oxidation.
