Disassemble Turbocharger

START BY:

a) remove turbocharger

1. Install turbocharger on tool group (A). Put marks on the three housings of the turbocharger for correct installation and alignment at assembly.

2. Remove eight bolts (1) and lockwashers. Remove four plates and compressor housing (2).

3 Remove two locks, two plates and four bolts (3) that hold the cartridge housing to the turbine housing. Remove cartridge housing (4).


NOTICE

Do not put a side force on the shaft when the nut is loosened.


4. Put the cartridge assembly on tool (B) as shown. Use tool (C) and the correct size socket to remove the nut that holds compressor wheel (5) on the shaft.

5. Hold the cartridge assembly down in tool (B) nd lift and turn the compressor wheel (5) at the same time to remove it from the shaft.

6. Remove cartridge assembly (6) from the shaft.

7. Remove bearing (7) and ring (8) from the shaft.

8. Remove ring (9) from the housing assembly with tool (D).

9. Remove the insert, sleeve and deflector from the housing assembly as a unit. Use two screwdrivers to remove the unit.

10. Remove O-ring seal (14) from insert (13). Remove sleeve (10) from the insert and deflector (11). Remove ring (12) from the sleeve.

11. Remove bearing (15) from the housing assembly.

12. Turn the housing assembly over. Remove shroud (16) and the gasket from the housing assembly.

Assemble Turbocharger

1. Make sure that all of the oil passages in the cartridge housing assembly are clean and free of dirt and foreign material. Put clean oil on all the parts of the cartridge assembly.

2. Put shaft (1) in position in tool (A). Install ring (3) and bearing (2) in the shaft as shown.

NOTE: Put 6V2055 High Vacuum Grease in the groove for seal ring (3) at assembly to one half or more of the depth of the groove all the way around the shaft.

3. Put shroud (4) in position on the shaft as shown.

4. Put gasket (6) in position on the shroud. Install housing assembly (5) over the shaft.

5. Install bearing (7) in the housing assembly. Make sure the bronze side of the bearing is up.

6. Put deflector (9) in position over sleeve (8).

7. Install ring (10) in the groove on the sleeve. Push the sleeve into insert (11). Install O-ring seal (12) on the insert.

8. Install the insert, deflector and sleeve as a unit in the housing assembly as shown.

9. Install ring (13) in the grove in the housing assembly with tool (B).

10. Put compressor wheel (14) in position on the shaft.

11. Put 6V1541 Quick Cure Primer on the nut and the shaft threads to clean them. Put a small amount of 3S3265 Retaining Compound on the nut and shaft threads.


NOTICE

Do not let the retaining compound get into the compressor wheel bore on the shaft, it will make removal of the compressor wheel difficult during future turbocharger disassembly.


12. Put a small amount of lubricant, such as Lubriplate, on the area of the nut that makes contact with the compressor. Do not put lubricant on threads.


NOTICE

Do not put a side force on the shaft when the nut is tightened.


13. Install the nut on shaft. Use a torque wrench and flexible socket and tighten the nut to a torque of 44 ± 2 lb.ft. (60 ± 3 N·m.).

14. Put the cartridge in a vise as shown. Check the shaft end play with tool (D). The end play must be .002 to .005 in. (0.05 to 0.13 mm) for a new shaft.

15. Put turbine housing (15) in position on tool (C). Put cartridge assembly (16) in position in the housing. Make sure the mark on the cartridge assembly is in alignment with the mark on the housing. Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold cartridge assembly to the turbine housing. Install the two locks, two plates and four bolts that hold the cartridge assembly to the turbine housing. Tighten the bolts to a torque of 11 to 12 lb.ft. (15 to 17 N·m). Bend the locks over the bolts.

16. Put compressor housing (17) in position on the cartridge assembly. Make sure the mark on the housing is in alignment with mark on the cartridge assembly. Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold the compressor housing to the cartridge assembly. Install the four plates and eight bolts and lockwashers that hold the compressor housing in position. Tighten the eight bolts to a torque of 60 lb.in. (6.8 N·m).
