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 fit 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 flinger
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.
