11. Thread dust seal and seal retainer into groove at end

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

Table 1 - Recommended Oil Viscosity

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

straight mineral type, with rust and oxidation inhibitor and anti-

foam agent only.

ISO32 -

ISO68 -

335 SUS at 100°F; 55 SUS at 210° F

ISO100 -

495 SUS at 100°F; 66 SUS at 210° F

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.
