II. Application
Lubricate all gears, pinions, bearings, shafts, gas-
kets, seals (o-rings) and contact surfaces as they
are being assembled.
Contact surfaces •
Apply grease liberally to all mating surfaces.
O-Rings •
Fill grooves with grease before installing o-rings.
Gaskets •
Gasket and gasket surfaces should be greased
on both sides prior to installation.
Bearings •
Sleeve type bearings should be coated with
grease before they are pressed into the hous-
ing. Thrust washers should be coated with
grease on both sides prior to installation.
Shafts •
Lubricate shafts before installing them into
the housing.
Pinions and other spur gears •
Grease should be applied to the gear teeth in
such a way that it is carried through the meshing
of the gears. After applying the grease, rotate
the gears enough times so that the slowest gear
in the set makes at least two (2) revolutions.
Worm and worm gear set •
Lubricate both hubs and shoulders of the
worm gear prior to installing it in the hous-
ing. Apply grease to the worm and worm gear
teeth in such a way that it is carried through
the meshing of the gears. After applying the
grease, rotate the worm enough times so that
the worm gear makes at least two (2) complete
cycles (one cycle being from closed to open
to closed or open-closed-open). After cycling,
inspect and re-apply grease if necessary.
Note: Gear operators intended for marine ser-
vice or buried service, and so specified on the
Purchase Order or Sales Order, must have the
housing(s) filled with grease.
