Put clean engine oil on all parts of the cartridge at assembly. Make sure the round edge of the outside diameter of the retainer rings are toward the bearings when the retainer rings are installed. 3. Using tool (C), install retainer ring (22) in the turbine end of the cartridge housing.4. Install washer (21) and bearing (20). Using tool (C), install retainer ring (19). 5. Using tool (C), install retainer ring (18). 6. Install washer (23) and bearing (17) in the cartridge housing until washer (23) makes contact with retainer ring (18). 7. Install thrust bearing (16) over the dowels in the cartridge housing. Make sure the grooves in bearing (16) are toward the outside as shown. 8. Install seal ring (15) in the groove of the cartridge housing. 9. Install thrust collar (14) on the thrust bearing with the counterbore for the spacer up. 10. Install seal rings (13) on spacer (12) so that the gaps in the rings are 180° apart. 11. Install spacer (12) in backplate assembly (11). 12. Align oil passage (24) in the cartridge housing with oil passage (25) in the backplate assembly. Install backplate assembly (11) on the cartridge housing.
