Remove bearing (22) from the cartridge housing. 17. Remove snap ring (23) from the cartridge housing with Tool (B).Assemble Turbocharger
Make sure all the oil passages in the turbocharger cartridge housing are clean and free of dirt and foreign material. Put clean engine oil on all parts of the cartridge assembly.1. Install snap ring (1) in the cartridge housing with Tool (A). Make sure the oil hole in plate (5) is open and clean to prevent a bearing failure.2. Install bearing (2), collars (3), plate (5) and screws (4). Tighten the screws to a torque of 2.5 N m (22 lb in).
Install the rings with the round edge of the outside diameter of the rings toward the bearings.
3. Turn the cartridge housing over. Install snap ring (6) in the cartridge housing with Tool (A). Install bearing (7), ring (8) and ring (9) in the housing. Install snap ring (10) with Tool (A). Put 6V-2055 High Vacuum Grease in the grooves for seal rings (11) at assembly to one half or more of the depth of the groove all the way around the grooves.4. Install seal rings (11) on spacer (12). 5. Install spacer (12) in the backplate. 6. Put backplate (13) in position on the cartridge housing, and install the bolts that hold it. Tighten the bolts to a torque of9.5 1.m (84 lb in). 7. Put shroud (14) in position on the cartridge housing. Put 6V-2055 High Vacuum Grease in the groove for the oil seal ring on shaft and wheel assembly (15).8. Install shaft and wheel assembly (15) in the cartridge housing. 9. Put the cartridge assembly in position in Tooling (B).10. Put a small amount of clean engine oil on the wheel face that will be under the nut.11. Put compressor wheel (17) in position on the shaft.
Do not put a side force on the shaft when the nut is tightened.
12. Install nut (16), and tighten it to a torque of 4 N m (35 lb in). Tighten the nut 120 degrees(1/3 turn) more. 13. Put the cartridge assembly in a vise. Use Tool (C) to check end play. The end play must be 0.051 to 0.081 mm (.0020 to .0032 in). 14. Put a small amount of clean engine oil on O-ring seal (18); then install it on the cartridge housing. 15. Put the cartridge housing on compressor housing (20), and install plates (21) and bolts (19). 16. Put turbine housing (22) in position on the cartridge housing, and install clamp (23) that holds it. Tighten the clamp to a torque of 14 1 N m (10 1 lb ft).End By:a. install turbocharger
