START BY:a. remove turbocharger The illustrations and procedure which follow were performed on the T04. 1. Put the turbocharger in position on tool (A).2. Put an alignment mark on compressor housing (1) and the backplate assembly for use at assembly. Remove the compressor housing from the backplate assembly. 3. Change the position of tool (A) so the compressor wheel is up as shown.4. Put an alignment mark on housing (2) and turbine housing (3) so that the housing can be put back in the same position in the turbine housing at assembly.5. Remove the bolts, lockplates and clamps that hold the housing in the turbine housing, and remove the housing. 6. Put the housing in position on tool (B).
Do not put a side force on the shaft when the nut is removed.
7. Use tool (C) and a socket of the correct size to remove nut (5) from the shaft.8. Remove compressor wheel (4) from the shaft.9. Remove the housing from the shaft. 10. Remove shroud (6) from the turbine wheel and shaft. 11. Remove seal ring (7) from the turbine wheel. 12. Put an alignment mark on the housing and backplate assembly for use at assembly. Remove the bolts and plates that hold the housing to the backplate assembly. Remove the housing.13. Remove bearing (8), collar (9) and the seal ring from backplate assembly (10).14. Remove the seal ring and bearing from the collar. 15. Remove seal ring (11) from the housing.16. Remove the snap ring, bearing (12) and the snap ring from each side of the housing.Assemble Turbocharger (AiResearch T04 or TW4)
The illustrations and procedure which follow were performed on the T04.1. Make sure the oil passages are clean and free of all dirt or foreign material. Put clean engine oil on all of the parts before assembly.
The snap rings must be installed with the rounded outside edge toward the bearing.
2. Install the inner snap ring, bearing (1) and snap ring (2) in each side of the housing. 3. Install the seal ring on collar (4).4. Put bearing (3) in position on the collar.
The oil grooves in the bearing must be clean and free of all dirt or foreign material. The bearing must be installed with the oil grooves toward the housing.
5. Put the bearing and collar in position on the housing so the oil grooves in the bearing are toward the housing and the holes in the bearing are in alignment with the pins in the housing.
Be extra careful during installation of the bearing and collar not to cause damage to the seal ring on the collar.
6. Install the seal ring on the housing.7. Put the backplate assembly in position on the housing respective to the alignment marks put on the housing and backplate at disassembly. Install the plates and bolts. Tighten the bolts to a torque of 8.5 to 10.2 N m (75 to 90 lb.in.). 8. Install shrould (5) on the housing. 9. Put 6V2055 High Vacuum Grease in the groove for seal ring (7). 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. Install seal ring (7) with tool (C). Carefully install turbine wheel and shaft (6) in the housing. 10. Put the housing, turbine wheel and shaft and the backplate assembly in position on tool (A). 11. Install compressor wheel (8) on the turbine shaft.
Do not put a side force on the shaft when the nut is loosened or tightened.
12. Put clean engine oil on the threads of the shaft. Install the nut that holds the compressor wheel in place. Tighten the nut to a torque of 2.3 N m (20 lb.in.). Put a mark on the nut and shaft. Tighten the nut 110° more with tool (D).13. Remove the nut, and clean the threads of the shaft and nut with 6V1541 Quick Cure Primer.14. Put 9S3265 Retaining Compound on the threads of the shaft and nut. Install the nut, and tighten it to a torque of 2.5 N m (20 lb.in.). Put a mark on the nut and shaft. Tighten the nut 110° more with tool (D).
Typical Example15. Check the shaft end play with tooling (E). See the Specifications section for the proper amount of shaft end play of new and used turbochargers. 16. If the turbine housing was removed from tool (B), put the turbine housing in position on tool (B).17. Put the housing and wheels in position in the turbine housing respective to the alignment marks put on the housings at disassembly. 18. Put 5P3931 Anti-Seize Compound on the threads of bolts (9). Install the clamps, lockplates and the bolts (9). Tighten the bolts to a torque of 13 1.7 N m (115 15 lb.in.). Bend the lockplates against the bolt heads. 19. Put compressor housing (10) in position on the backplate assembly respective to the alignment marks on the housing and backplate assembly at disassembly.20. Install the clamps, lockplates and bolts that hold the compressor housing in place. Tighten the bolts to a torque of 13 1.7 N m (115 15 lb.in.). Bend the lockplates against the bolt heads.21. Remove the turbocharger from tool (B).END BY:a. install turbocharger
