See Special Instruction Form No. SMHS6854 for Turbocharger Reconditioning. Also, see Guidelines for Reuseable Parts, Form No. SEBF8018.Assemble Turbocharger
1. Make sure that all of the oil passages in the turbocharger cartridge housing are clean and free of dirt and foreign material. Do not put oil on any parts of the turbocharger until after the compressor wheel has been installed. After the turbocharger has been assembled, put clean engine oil into the oil inlet of the turbocharger.
Make sure that the snap rings that hold bearings (2) and (5) in position in housing assembly (3) are installed with the round edge of the outside diameter toward the bearing.
2. Install the snap ring behind bearing (2) with tool (A).3. Install bearing (2) in housing (3).4. Use tool (A) and install snap ring (1) in the housing assembly. 5. Install the snap ring behind bearing (5) with tool (A).6. Install bearing (5) in the housing assembly.7. Use tool (A) and install snap ring (4) in the housing assembly. 8. Put wheel assembly (8) in position on tool (B) as shown.9. Put backplate (7) in position on the wheel assembly. Put 6V2055 High Vacuum Grease in the groove for seal ring (6) at assembly to one half or more of the depth of the groove all the way around.10. Install ring (6) in the groove in wheel assembly (8). 11. Put housing assembly (3) in position on wheel assembly (8). 12. Install ring (9) and sleeve (10) on the wheel assembly. 13. Make sure screen is in place in bearing assembly (11). 14. Install bearing assembly (11) over the sleeve. Make sure the screen in the bearing assembly is facing down when it is installed.15. Put ring (12) in position on bearing assembly (11). 16. Put deflector (14) in position in the housing assembly and install two screws (13). Put 6V2055 High Vacuum Grease in the groove of sleeve (15) to one half or more of the depth of the grooves all the way around.17. Install ring (16) in the groove in sleeve (15). 18. Put sleeve (15) in position in insert (17). Install the insert and sleeve (15) as an assembly. 19. Use tool (C) and install snap ring (18) to hold insert (17) in place. 20. Put wheel (21) in position in compressor housing (20). Center the wheel in the compressor housing.21. Use a straight edge and a depth micrometer (19) and measure the distance between the wheel seating face and the compressor housing mounting face (dimension X) in four places. Find the average of the measurements. 22. Use a depth micrometer (19) to measure the distance between the face of housing assembly (3) and the surface of sleeve (15) (dimension Y).23. Use a depth micrometer (19) and measure the distance between the surface of housing assembly (3) and the compressor housing mounting face (dimension Z).24. Calculate the necessary shim thickness as follows: The shims must be of uniform thickness and free of burrs and other imperfections. The total shim thickness should be 0.13 mm to 0.41 mm (.005 to .016 in.) and consist of one or two shims.25. Install wheel (21) at room temperature as follows:a. Put the correct amount of shims and wheel (21) in position on the wheel assembly.b. Put a small amount of clean engine oil on the threads of the wheel assembly.
Do not put a side force on the shaft when the nut that holds the compressor wheel in position is tightened.
c. Install the nut that holds wheel (21) in place. Tighten the nut to a torque of 14 to 17 mm (125 to 150 lb. in.).d. Remove the nut and put 6V1541 Quick Cure Primer on the threads of the wheel assembly.e. Put 9S3265 Retaining Compound on the threads of the wheel assembly and install the nut. Tighten the nut to a torque of 4 mm (35 lb. in.).f. Tighten the nut an additional 90°. 26. Install housing (23) on tool (D) as shown.27. Put housing assembly (3)
