start by: a) remove turbocharger (130G & 120G) 1. Put the turbocharger in position on tool (A).2. Put a 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 on tool (A) so the compressor wheel is up as shown. 4. Put a 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).7. Remove nut (5) from the shaft.
Do not put a side force on the shaft during removal of the nut.
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 a 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 (130G & 120G)
1. Make sure all oil passages are clean and free of all dirt or foreign material. Put clean engine oil on all of the parts before assembly.2. Install the inner snap ring, bearing (1) and snap ring (2) in each side of the housing. The snap rings must be installed with the round side toward the bearing. 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 the collar in position on the housing so that 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 marks put on the housing and backplate at disassembly. Install the plates and bolts. Tighten the bolts to a torque of 50 10 lb.in. (5.7 1.1 N m). 8. Install shroud (5) on the housing. 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. 9. Install seal ring (7). 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.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 20 lb. in. (2.3 N m). Put a mark on the nut and the shaft. Tighten the nut 100° more.
When tightening the nut, do not put a side force on the shaft.
13. If the turbine housing was removed from tool (B), put the turbine housing in position on tool (B). 14. Put the housing and wheels in position in the turbine housing respective to the marks put on the housings at disassembly. 15. Put 5P3931 Anti-Seize Compound on the threads of bolts (9). Install the clamps, lockplates and the bolts. Tighten the bolts to a torque of 115
