of housing base and around shaft. Slide free end of seal
retainer through clasp and pull tightly. Hold clasp and
tighten as shown in Figure 1. Cut off excess material and
break off clasp lip, discarding it so it won't drop in housing
bottom. Seal retainer may be disengaged before installation
by inserting a straightened paper clip between the bands
at the clasp and pulling the free end of the retainer out of
the clasp.
Figure 1 - Seal Retainer Installation
To properly tighten seal retainer, hold clasp stationery with a
screwdriver, grasp free end of retainer with pliers and rotate
pliers toward screwdriver.
Aluminum seals, when specified for the application,
are packaged separately. When using aluminum seals,
discard standard seals and seal retainers packaged with the
housing. To install aluminum seals, first take O-ring (rubber
cord), wrap it around the shaft in the seal area and cut it to fit
the shaft. Disassemble one seal and place one half on shaft.
Locate O-ring in seal groove and rotate seal half around
shaft into housing base groove. Install other half of seal
and tighten clamp screws. For most effective sealing, the
ends of the O-ring must meet. Cementing ends together is
recommended. Install other half of seal and tighten screws.
Install second seal in same manner. If using End Closure,
neoprene discs should be installed at this time. Consult
construction drawing for type of seal recommended.
12. We have replaced SLEEVOIL housing gaskets with 515
Gasket Eliminator. Apply Gasket Eliminator to SLEEVOIL
housing base along outer contour of joint. Special care
should be taken at grommet area.
Back off plunger screw completely and locate housing
cap on base taking care not to damage dust seals. Tighten
housing bolts to 8330 in.-lbs. To reduce chances for leakage,
a non-hardening sealant must be used under cap bolts. The
plunger screw must be loose until the housing bolts
have been tightened. Tighten plunger screw to 4800 in.-
lbs.
These SLEEVOIL Housing have match-marks permanently
stamped on the water pipe grommet pad. These match
marks permanently insure that parts stay paired and critical
orientation of assemblies is maintained.
Cap Loaded Bearings: If shaft must be held down to install
cap, tighten plunger screw to recommended torque of
4800 in.-lbs. with shaft held down. Mark position of plunger
screw. Loosen plunger screw one complete turn and
loosen shaft hold down. Then tighten plunger screw while
tightening shaft hold-down until plunger screw is tightened
to the mark. Do not over-tighten shaft hold-down as this can
misalign the bearing. Remove shaft hold-down and tighten
plunger screw locknut.
NOTE: Do not tighten plunger screw on accompanying
base loaded bearing until cap loaded bearing has been
installed and hold down removed.
Base Loaded Bearings: Tighten plunger screw to
recommended torque of 4800 in.-lbs. and tighten locknut.
tighten housing cap bolts to 8880 in.-lbs.
IMPORTANT: Check and re-torque plunger screw to the
specified torque after 24 hours of initial start-up and then
check and retorque periodically as required.
13. The oil level gauge may be located any distance from the
pillow block by the use of a coupling and pipe of the desired
length. The extended pipe must be supported so that it
remains straight and perfectly level. Use a spirit level - do
not guess. Use pipe sealer on all connections.
14. Remove all pipe plugs and flush liner bore and housing
thoroughly with solvent or cleaner. Reinstall pipe plugs using
pipe sealer. Tighten securely.
15. Each housing base has predrilled holes for doweling bearing
to base plate.
Lubrication and Operation
Since the satisfactory operation of the pillow block depends
almost entirely on the oil film being maintained between the shaft
and liner bearing surface, it is recommended that a high grade
straight mineral oil with rust and oxidation (R & O) inhibitors and
anti-foam agents be used. Check equipment specifications
for specific recommendation of oil viscosity by equipment
manufacturer. Oil viscosity is determined by the equipment
manufacturer and normally specified on the construction drawing

Use high grade, high quality, well refined petroleum oils of the

foam agent only.

NOTE: The recommended oil temperature at start-up is 70ºF
MINIMUM.
Low ambient and operating temperatures can be as harmful to
the bearing as high temperatures. A heater and thermoswitch
would be required for such applications.
Fill the pillow block with oil to the top of the center circle in the
oil gauge. After placing into operation, remove inspection covers
and check to make sure oil rings are bringing up oil. Operation
should be checked frequently during the first few days. After some
running of base loaded bearings only, loosen plunger screw 1/4
turn, then retighten. This will allow the liner to align with the shaft.
For cap loaded bearings, follow installation procedure. If noise
develops, check alignment of housing, collar runout, plunger
screw and all operating parts. Check all points and make sure
all screws and nuts are tightened after several days operation.
