install retaining 3. If the housing (15) has been com- ring pletely disassembled, place the housing, mounting flange end down, on a clean work surface. Install retaining ring (18) into the housing retaining ring groove.  Be sure the rounded edge of retaining ring is facing in toward the larger housing cavity.  Use appropriate retaining ring pliers.  SEE FIGURE 31, press in bearing 4. Thoroughly grease the rolls of a NEW bearing (19) with clean wheel bearing.  grease.  Press the bearing into housing (15) from the mounting flange end of the housing bore, using bearing mandrel (special tool FIGURE 1, Page 7A) against the lettered end of the bearing shell.  SEE FIGURES 32 and 33.  Take care during this procedure that the housing is square with the press base and that the bearing is not cocked.  The bearing mandrel will control the bearing (19) press depth to the required .135/.125 inches (3.43/3.18 mm) from the flange end of the housing. NOTE: NOTE:  If the bearing mandrel shown is not available, alternate methods may be used to press in the bearing but the bearing depth location must be maintained. CAUTION CAUTION:  The controlled press depth of bearing (12) and (19) into the housing is required to ensure adequate bearing support, and correct bearing relationship to adjacent components when assembled. CAUTION CAUTION:  Because bearings (12) and (19) have a press fit into the housing, they must be discarded if removed from the housing.  They must not be reused. 16
