1. Loosen two hose clamps (4).2. Slide hose assembly (1) off the turbocharger.3. Remove bolt (2).4. Remove four nuts (3) and washers.5. Remove tube assembly (6). Check gasket and O-ring for wear or damage. replace if necessary.6. Remove clamp bolt (5).7. Remove two bolts (9).8. Disconnect oil supply tube connector (16).9. Remove oil supply line (13). Check gasket for wear or damage. Replace if necessary.10. Remove two bolts (11).11. Remove oil return line (15). Check gasket and O-ring for wear or damage. Replace if necessary.12. Remove four bolts (14).13. Remove support (12) and elbow (10) as a unit.14. Remove four bolts (8) (not shown).15. Remove turbocharger (7) and gasket. When assembling use a new gasket. Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold the turbocharger to the exhaust manifold. Tighten the bolts to a torque of 75 10 N m (55 7 lb ft). For installation of the turbocharger, reverse the removal steps.End By:a. install hood assemblyDisassemble Turbocharger
Start By:a. remove turbocharger 1. Install the turbocharger on Tool (A).2. Put marks on the housings for correct installation at assembly.3. Loosen clamp (1) Remove compressor housing (2). Remove the clamp. 4. Remove bolts (3), locks (6) and plates (5).5. Remove the center section from turbine housing (4). 6. Install Tool (C) in Tool (B). Install the center section in Tool (C) as shown.7. Remove nut (7) that holds the impeller to the shaft and wheel assembly. 8. Install Tool (E) on Tool (D). Heat Tool (D) to 177°C (350°F). Install the impeller on Tool (E).
Make sure only the impeller is in the hot oil.
9. Install Tool (E) with the center section on Tool (F). Remove impeller (9) with an arbor press and Tool (G). Step 9 must be done before the impeller gets cold. 10. Remove shaft and wheel assembly (10), shroud (11) and spacer (13) from center housing (12). 11. Remove bolts (14), locks (15) and plate (16) from the center housing. 12. Remove collar (17). 13. Remove two bearings (18) and three snap rings (19) from the center housing.Assemble Turbocharger
1. Clean all parts thoroughly before assembly.2. Install snap ring (15), bearing (12) and snap ring (11) in center housing (10). Install snap ring (9) and bearing (8).3. Install shroud (13). Put 4L7464 Silicone Grease in the turbine end seal ring groove. Make sure it fills approximately one half or more of the groove depth for the complete circumference of the groove. Install shaft and wheel assembly (16) in the center housing.
Use caution not to cause damage to ring seal (14) when the shaft and wheel assembly is installed.
4. Install spacer (7) and collar (6).5. Put plate (5) in position on the center housing. Install bolts (4). Tighten the bolts to a torque of 4.0 0.6 N m (35 5 lb in).6. Install spacer (3). Make sure the small inside diameter of the spacer is toward the impeller end of the shaft and wheel assembly.
Install spacer (3) with the small inside diameter away from center housing (10) or it will cause a restriction of oil flow to the chamber and rings. This will cause a failure of the turbocharger.
7. Heat impeller (1) in oil to a maximum temperature of 177°C (350°F). Install the impeller on the shaft and wheel assembly.8. Install Tool (C) in Tool (B). Install the center section in Tool (C). Install nut (2). Tighten the nut to a torque of 13.6 N m (120 in lb). Let the temperature of the impeller get below 65°C (150°F). Loosen the nut. Put a small amount of oil on the threads of the shaft and wheel assembly. Tighten the nut again to a torque of 3.4 N m (30 lb in). Put a mark on the nut and impeller. Tighten the nut 120° past the mark.
Do not put a bending force on the shaft and wheel assembly when nut (2) is tightened.
9. Install turbine housing (17) on Tool (A). Install the center section in the turbine housing. Put the marks that were made at disassembly in alignment to make sure the housings are in their original position. 10. Put 5P3931 Anti-Seize Compound on the threads of bolts (21). Install plates (20), locks (19) and the bolts. Tighten the bolts to a torque of 19.8 1.7 N m (175 5 lb in).11. Install a new O-ring seal (18) on the center housing. 12. Put clamp (23) over the center section. Put compressor housing (22) in alignment with the marks made at disassembly. Put the clamp in position over the housing. Tighten the clamp to a torque of 13.6 1.1 N m (120 10 lb in).13. Put oil in the center section and turn the shaft and wheel assembly.End By:a. install turbocharger
