LUBRICATION
Force Feed Lubrication (FFL)
-- Timing gears and
bearings are lubricated by a pressure system which
features large diameter piping. A reversible oil pump
brings oil from an oversize sump which is large enough
to eliminate the need for an oil cooler at discharge
temperatures up to 325
_
F. (When not required, oil
coolers are available as optional equipment). An oil
strainer is located in the sump.
Splash--Lubrication
-- The gear end and drive end of
the blower are lubricated by the splash method. Oil is
picked up from the sump and thrown out by the gears
in the gear end and by an oil slinger on the drive end.
Both gears and bearings are lubricated in this manner.
Approximate oil sump capacities in U.S. gallons are
listed in FIGURE 6, page 7.
The factory recommended lubricant is AEON PD
Synthetic Lubricant.
AEON PD is formulated
especially for positive displacement blowers to provide
maximum protection at any temperature. One filling of
AEON PD will last a minimum of 4 times longer than a
premium mineral oil, depending on actual operating
conditions. AEON PD contains a special additive
package designed for greater rust and corrosion
protection.
Order AEON PD from your Sutorbilt Distributor or call
Gardner Denver Customer Service to find your nearest
distributor. A food--grade formula is also available. Part

Machines are shipped without oil in
the sumps. Do not operate before
adding lubricant.
LUBRICATION INSTRUCTIONS
Remove the vented fill (oil breather) caps (B) in
FIGURE 5. Do not remove any pipe plugs on top of the
headplates. Fill sumps through the breather cap stand-
pipes. When filling housing with oil, stop filling as soon
as the oil appears in the sight glass and allow a few
minutes for the level to stabilize. Once oil level has
stabilized, add or drain as necessary to adjust the oil
level to the midpoint of the sight glass. Be sure fill caps
are secured in place once proper oil level is obtained.
Force--Feed lubricated blowers have a common line
between oil sumps and oil can be added at either the
drive end or gear end. Splash--lubricated blowers have
separate oil sumps and oil must be added at both the
drive end and gear end.
Check the oil level after the initial operation.
Maintain
oil level at the midpoint of the sight glass when the
blower is not operating.
It may be necessary to add
oil to maintain this level as oil will migrate to fill the
lubrication passages.
