WARNING: All products over 25 kg (55 lbs) are noted on the
shipping package. Proper lifting practices are required for
these products.
WARNING: To ensure that drive is not unexpectedly started,
turn off and lock out or tag power source before proceeding.
Failure to observe these precautions could result in bodily
injury.
CAUTION: Do not scrape, rebabbitt or otherwise alter this
product. Such action adversely affects bearing performance
and may result in damage to or destruction of equipment.
INSTALLATION
1. Check
mounting structure
making sure it is rigid, level
and well supported. Inspect shaft to insure it is smooth (32
micro-inch finish or better), within commercial tolerances
and free of burrs or rough spots.
2. Disassemble and thoroughly clean all parts of the pillow
block. Housing caps and liner caps are matched to their
bases and should not be interchanged. Housing and liners
should be interchanged as assemblies only.
WARNING: Rust preventatives and solvents can be toxic
and/or flammable. Follow directions and safety procedures
recommended by their manufacturers.
CAUTION: Liner assembly has critical machines surfaces
which are easily damaged. Use care in handling to protect
these surfaces. Liner parts should be placed on a soft,
CLEAN surface.
3. Position
housing base
on pedestal so that oil gauge is
in the position specified on the construction drawing.
Do
not tighten housing base to pedestal
. Apply oil to the
spherical seats in the housing base.
4. Set liner base in housing base and apply oil to liner bearing
surface.
CAUTION: Care should be taken when reinstalling coolant
pipes. Use pipe sealant and tighten securely. Over tightening
may result in liner damage.
5. Apply oil to
shaft
in the bearing area and set shaft in place.
6. Check alignment
of pillow block by noting clearance
between housing and shaft at each end of the housing—
clearance should be uniform within 1/32”. Shim bearing
pedestal where possible, otherwise use full length shims
under base as required. Alignment of pillow block should
be as accurate as possible. The self-alignment feature of
the unit is to compensate for normal shaft deflection and
possible setting of the supports.
WARNING: Because of the possible danger to persons(s) or property
from accidents which may result from the improper use of products,
it is important that correct procedures be followed. Products
must be used in accordance with the engineering information
specified in the catalog. Proper installation, maintenance and
operation procedures must be observed. The instructions in the
instruction manuals must be followed. Inspections should be made
as necessary to assure safe operation under prevailing conditions.
Proper guards and other suitable safety devices or procedures as
may be desirable or as may be specified in safety codes should
be provided, and are neither provided by Dodge nor are the
responsibility of Dodge. This unit and its associated equipment must
be installed, adjusted and maintained by qualified personnel who are
familiar with the construction and operation of all equipment in the
system and the potential hazards involved. When risk to persons or
property may be involved, a holding device must be an integral part
of the driven equipment beyond the speed reducer output shaft.

*Short Series
7. Place
oil rings
around outside of lower liner and over shaft.
Secure and tighten screws. Oil ring halves are machined
together and match marked. Upper and lower halves should
not be changed with components from other oil rings. Make
sure rings rotate freely on shaft.
8. Apply oil to bearing surface of
liner cap
. Locate cap in place
on lower liner making sure oil ring is free to rotate.
The Sleevoil liners 2-15/16” thru 3-7/16” have upper halves
that are normally reversible on the lower half. By design, they
are not doweled together and therefore not match-marked.
The only modification which requires match-marking of
these ‘PL-WC’ liners, 2-15/16 and 3-7/16 is:
When Liners Have a Cylindrical Bore
. (Since the location
of the bore centerline to the liner dowels is then rigidly fixed,
an upper liner reversed on a lower or interchanged halves
from two different liners can severely change the clearances
between shaft and liner bore.)
9. Tighten
housing base
to pedestal. Torque bolts to 2100 in-
lb. Shaft should rotate freely.
10. Size 2-15/16”
- Thread
dust seal
and
seal spring
into
groove at end of housing base and around shaft. Hook
ends of spring together; taking care not to overstress spring
when stretching. Permanent set can cause loss of working
load and looseness on shaft; resulting in oil leakage during
operation.
Size 3-7/16”
- Thread dust seal and seal retainer into
groove at end of housing base and around shaft. Slide free
end of seal retainer thru clasp and pull tightly. Hold clasp
with screwdriver and pull free end of retainer as tightly as
possible with pliers. If tightened properly, it will be difficult
to move seal sideways. Cut off excess material, and discard
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. If unit is furnished
with auxiliary seals, install a second seal on each end.
If using End Closure
, neoprene discs should be installed at
this time.
Consult construction drawing for type of seal
recommended.
11. Apply Gasket Eliminator to Sleevoil housing base along
outer contour of joint. Loosen plunger screw and locate
housing cap on base taking care not to damage dust seals.
To reduce chances for leakage, a non-hardening sealant
must be used under cap bolts. Torque housing bolts to value
given in Table 2.
The plunger screw must be loose until
the housing bolts have been tightened.
These Sleevoil ‘PL-WC’ housings have match marks
permanently stamped on the water grommet pad starting
in June 1988. These match marks permanently insure that
parts stay paired and critical orientation of assemblies is
maintained.
12. Cap Loaded Bearings:
Shaft must be held down to install
cap, tighten plunger screw to recommended torque given
in Table 2 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.
