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). Put 4L7464 Silicone Grease in the groove for seal ring (3). Make sure the grease fills the groove approximately one half or more of the groove depth for the complete circumference of the groove to help make a carbon dam under the seal ring. Install seal ring (3) and bearing (2) in the shaft as shown. 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 groove in the housing assembly with tool (B). 10. Put compressor wheel (14) in position on the shaft.
Do not put a side force on the shaft when the nut that holds the compressor wheel in position is tightened.
TYPICAL EXAMPLE11. Install the nut that holds the compressor wheel in position. Tighten the nut to a torque of 165 15 lb.in. (18.7 1.7 N m). 12. 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 9M3710 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. 13. 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 9M3710 Anti-Seize Compound on the threads of the bolts that hold the compressor housing to the cartridge assembly.
