LUBRICATION
FIGUR E 3 -1 - LUBRICATION
DRIVE END LUBRICATION
Drive end bearings are grease lubricated at the factory with Lithium Complex based grease. For relubrication,
use Gardner Denver AEON PD Grease, Part Num ber 28H283. AEON PD Grease is a high temperature, high
performance grease that is formulated with antiwear additives to provide superior service under the severe
operating conditions of positive displacement blowers. It contains rust inhibitors which provide excellent
protection against rust and corrosion.
If you choose not to use AEON PD Grease, select compatible base grease. The grease should be NLGI
Grade 2 EP, contain rust inhibitors, and be suitable for blower discharge temperatures up to 350 ° F (177 ° C).
Completely clean or purge the factory-- filled grease from the blower. Do not mix different types of grease as
they may not be compatible. Substitutions may cause early bearing failure.
Re - grease bearings every 500 hours of operation. Lubrica te each bearing through the grease fittings located at C
in FIGURE 3 -1 (2 places). When re - greasing, the old grease will be forced out of the vents (E in FIGURE 3 -1 ).
To prevent damage to seals, these vents must be open at all times.
Do not over-- gre ase bearings as this could cause premature bearing failure.
GEAR END LUBRICATION
At the gear end, the timing gear teeth are lubricated by being partially submerged in oil. The gear teeth serve as
oil slingers for gear end b earings.
Approximate oil sump capacities are listed in FIGURE 3-2 , page 18 .
