bearing.
b.
If Locknut Facing Non-Expansion Bearing: Align
housing mounting holes with substructure mounting
holes and snug bolts. Position expansion bearing insert
in center of housing (Note: This is necessary due to the
fact that in the process of mounting, the bearing is being
drawn toward the locknut.).
NOTE: All weight must be removed from the bearing
when obtaining zero reference point.
3.
Follow steps 4 through 10 found under "Install the Non-

GREASE LUBRICATION
Dodge IP and ISAF bearings are pre-packed with NLGI #2
Lithium Complex grease. For relubrication, select a grease that
is compatible with a #2 Lithium Complex grease. Relubricate in
accordance with Table 3.
STORAGE OR SPECIAL SHUTDOWN
If exposed to wet or dusty conditions or to corrosive vapors, extra
protection is necessary. Add grease until it shows at the seals;
rotate the bearing to distribute grease; cover the bearing. After
storage or idle period, add a little fresh grease before running.
