Remove seal ring (8) and shroud (7) from shaft assembly (6). 6. Remove snap ring (9) with tool (B). 7. Use two screwdrivers to remove insert (10) from the cartridge housing. 8. Remove O-ring seal (12) from the insert.9. Remove sleeve (11) from the insert. Remove the seal ring from the sleeve. 10. Remove deflector (13) from the housing. 11. Remove ring (14) from the cartridge housing. 12. Remove sleeve (15) and bearing (16) from the cartridge housing. 13. Remove ring (17). 14. Use tool (C) to remove snap ring (19), bearing (18) and snap ring (20) from the cartridge housing. 15. Turn the cartridge housing over. Use tool (C) to remove snap ring (22), bearing (21) and snap ring (23) from the housing.Assemble Turbocharger (Schwitzer 4MF)
1. Make sure all oil passages are open and clean. Put clean engine oil on all parts before assembly. 2. Use tool (A) to install snap ring (23), bearing (21) and snap ring (22) in the housing. Install the snap rings with the round side toward the bearing. 3. Turn the housing over. Use tool (A) to install snap ring (20), bearing (18) and snap ring (19). Install the snap rings with the round side toward the bearing. 4. Put ring (17) in position in the housing. 5. Put bearing (16) in position. Make an alignment of the holes in the bearing with the dowels in the housing. Grooved side of the bearing must be up.6. Put sleeve (15) in position in the housing. 7. Put ring (14) in position on top of the bearing. 8. Install deflector (13) as shown. 9. Put seal ring (24) in position on sleeve (11). Install the sleeve in insert (10).10. Put O-ring seal (12) in position on the insert. 11. Put insert assembly (10) in position in the housing. 12. Use tool (B) to install snap ring (9) in the housing. 13. Put shaft assembly (6) in position on tooling (C).14. Put 6V2055 High Vacuum Grease in the seal ring groove on the shaft assembly.15. Install seal ring (8) on shaft assembly (6).16. Put shroud (7) in position on the shaft assembly. 17. Put cartridge assembly (4) and compressor wheel (5) in position on the shaft assembly.
Do not put a side force on the shaft when the nut is tightened.
18. Put a small amount of oil on the face of the compressor wheel that will be under the nut. Install the nut and tighten it to a torque of 60 3 N m (44 2 lb.ft.).19. Remove the nut and put 9S3265 Retaining Compound on the threads of the shaft. Install the nut and tighten to a torque of 60 3 N m (44 2 lb.ft.).20. Put the cartridge housing assembly in position in a vise with soft jaws. 21. Put tooling (D) in position and check the end play. The end play must be between 0.08 - 0.20 mm (.003 - .008 in.). 22. Put compressor housing (1) and turbine housing (2) in position and install clamps (3).23. Tighten the clamps to a torque of 13.6 1.1 N m (120 10 lb.in.).End By:a. install turbocharger
