These instructions must be read thoroughly before installation or operation. This instruction manual was accurate at the time of
printing. Please see dodgeindustrial.com for updated instruction manuals.
This manual is best suited for RTL Pillow Blocks. If your SLEEVOIL housing nameplate species “RTL SPHERICAL HOUSING,” use
manual MN3085. Dodge started manufacturing RTL SPHERICAL PILLOW BLOCKS in 2014.
PRE-ASSEMBLY INSTRUCTIONS
Refer to applicable contract/assembly drawings to verify that
all parts are available prior to assembly. Disassemble and
thoroughly clean all parts of the pillow block. The installer is the
last person to inspect all parts for t, damage and cleanliness.
Care MUST be taken to avoid contaminating the internal surfaces
of the bearing.
WARNING: Rust Preventatives and solvents can be toxic
and/or flammable. Follow directions and safety procedures
recommended by their manufacturers.
WARNING: Liner assembly has critical machined surfaces
which are easily damaged. Use care in handling to protect
these surfaces. Liner parts should be placed on a soft,
CLEAN surface.
For ease of installation, the housings and liners are split and
match-marked. The split halves are machined together and must
not be interchanged. The match-mark on the housing is found
near the joint in the grommet area. The match-mark on the liner
is found on the outer diameter of the pilot on one end of the liner.

INSTALL ATION OF BASES
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.
Check mounting structure to insure it is rigid, level and well
supported. Position housing base on pedestal so oil gauge is
in position specied on construction drawing. Do NOT tighten
housing base to pedestal.
Apply oil to the spherical seats of the housing base.
Set liner base in housing base.
Because of the closely controlled liner to housing t, it may be
necessary to bolt the housing base down to allow the liner to slip
into the housing seat. Do a preliminary alignment check at this
time.
Make sure the two thermocouple/RTD holes in the liner
are aligned with the two thermocouple/RTD holes in the
housing. Apply oil to the liner bearing surface.
NOTE: Liner has been machined to close tolerances.
Scraping of bore is not necessary.
INSTALLATION OF SHAFT AND
THRUST COLLAR
Inspect shaft to ensure it is smooth (32 micro-inch RMS or better)
and free of burrs and rough spots. Standard shaft diametrical
tolerance should be nominal +.000/-.002” unless otherwise
specied on shaft detail drawing.
If bearing is non-expansion (xed) type, check thrust collar for
burrs and scratches. Use crocus cloth (NOT emery) to smooth
any scratches on the thrust collar faces.
If clamp-on type thrust collar is used, make sure joints of collar
are clean. Place both halves of thrust collar into shaft groove
and tighten clamp screws alternately and evenly to torque value
specied in Table 1.
NOTE: Set and jam screws are shipped separately.
The collar faces must be smooth with no offset at the split.

3
Tighten set screws to value specied in Table 1. Install and
tighten jam screws 1/10 of torque specified for set screws.
Oil shaft in the bearing area and CAREFULLY set shaft in place.

The thrust collar must be centered in the cavity of the liner base.
INSTALLATION OF OIL RINGS
NOTE: Do NOT use oil rings if liner cap has baffles installed
in the oil ring grooves.
Oil rings are shipped disassembled with two extra screws. Place
oil rings around outside of liner base and over shaft.
NOTE: Oil ring halves are match-marked and MUST NOT be
interchanged.
Place oil ring around outside of liner base and over shaft.
Install oil ring screws to insure they are secure. Repeat for
second ring.
Make sure oil rings rotate freely on shaft.
INSTALLATION OF THRUST PL ATES
For non-expansion bearings:
Clean one set of babbitt faced thrust plates.
NOTE: Thrust plates are shipped in protective wax with the
babbitted faces on the outside. Be careful not to damage
the babbitted faces when peeling off the wax.
NOTE: Plates are matched halves and MUST NOT be
interchanged.
Carefully smooth any scratches on babbitted face with crocus
cloth (NOT emery cloth or sandpaper). Oil plate halves generously.

4
First, install the plate half without milled slots in the steel back.
Press the babbitted face against the thrust collar and rotate plate
around shaft into liner cavity.
Install retainer washer in groove in liner base. Rotate plate until
stopped by retainer washer.
Place the other thrust plate half (half with two milled slots in steel
back) against thrust collar, making sure babbitt faces thrust
collar.
Clean and oil the second thrust plate set and install in same
manner. It may be necessary to move the shaft slightly to obtain
enough clearance in the liner cavity to install the lower plate half.
CAUTION: The bearing is not yet fastened in place and can
be moved.
Total axial clearance between thrust plates and thrust collar is
.015 - .030 inches.
INSTALLATION OF LINER CAP
Apply oil to the bearing area of liner cap.
WARNING: If it ever becomes necessary to remove liner cap,
make certain that both upper thrust plate halves remain in
place next to the thrust collar. If a plate half should remain
in the liner cap it can drop from the liner and cause injury.
CAREFULLY locate liner cap on liner base. These SLEEVOIL
liners have match-marks permanently stamped at the joint near
one end. These match marks permanently insure that parts
stay paired and critical orientation of assemblies is maintained.
Makes sure oil rings rotate freely. End faces of liner should have
no appreciable offset.
Install cap screws and tighten alternately to torque given in Table
2.
NOTE: If liner cap on non-expansion bearing will not drop into
place, remove cap and reposition thrust plates tightly against
thrust collar. Reinstall liner cap.

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 accurate to prevent the seals
from rubbing.
Tighten the four pedestal bolts to torque value given in Table 3.
Shaft should rotate freely.
INSTALLATION OF OIL SEALS
Cut the O-ring (rubber cord) and wrap it around the shaft inside
the seal groove. If the O-ring is too large, cut it to t the shaft.
For most effective sealing, ends of O-ring must meet. Cement or
glue the ends together. Lubricate O-ring with oil or grease.
Apply a thin coat of heavy oil or light grease in the housing seal
grooves to extend seal life.
Disassemble one seal and place one half on shaft with inger
facing liner. Locate O-ring in seal groove and rotate seal half
around shaft into housing base groove.
Install other half of seal and tighten screws to torque given in
Table 3. Check to make sure the seal will slide along the shaft
with minimum effort to allow for shaft expansion. Align the seal in
the middle of the seal groove.
Install second seal in same manner. If end closure is to be used,
the neoprene disc is to be installed on one end at this time
instead of the bearing seal. Consult construction drawing.

INSTALLATION OF HOUSING CAP
Back off the plunger screw as far as possible.
Along the outer contour of the housing base, apply the supplied
LOCTITE® 515 or an equivalent sealant to the joint. CAREFULLY
place the housing cap on the base, and take special precautions
to prevent seal damage.
The plunger screw must remain loose until the housing bolts
have been tightened.
