start by: a) remove turbocharger 1. Put the turbocharger in position on tool (A).2. Put a mark on the compressor cover and housings for installation purpose.3. Remove "V" clamp (2) and remove compressor cover (1). 4. Remove "V" clamp (3) and remove shaft housing from turbine housing (4). 5. Put shaft housing in tool (B). Remove nut and compressor wheel (5) from the shaft.
When loosening the nut, do not put a side force on the shaft.
6. Remove shaft housing from tool (B) and remove turbine wheel (7) and shaft from housing.7. Remove seal ring (6) from the turbine wheel. 8. Remove snap ring and insert (8) from the housing. 9. Push the sleeve (9) out of the insert. Remove the two seal rings from the sleeve. 10. Remove deflector (10), ring (15), sleeve (11), bearing (12), ring (16), snap ring (13), bearing (17) and snap ring (14) from the housing. Remove snap rings (13) and (14) with tool (C). Check the oil hole in bearing (12). If the oil hole is not open this will cause a bearing failure. 11. Turn the housing around and remove snap ring (18) and shroud (22).12. Remove snap ring (19), sleeve (20), bearing (21), and snap ring (23). Remove the two snap rings with tool (C).13. Inspect all parts and install new parts as needed.Assemble Turbocharger
1. Make sure all oil passages are open and clean. 2. Install snap ring (4), bearing (3), sleeve (2) and snap ring (1). Install the two snap rings with tool (A). Install the snap rings with the round side toward the bearing. 3. Install shroud (5) on the housing. Turn the shroud to make sure it is down on the housing even. The purpose of the high part (web) (6) on shroud is so the shroud will not turn on the housing after assembly.4. Install snap ring that holds the shroud in place.5. Install the bearing and turn snap rings in the compressor end of the housing. Install the snap rings with tool (A). Install the snap rings with the round side toward the bearing. 6. Install seal ring (7) on the shaft. Install turbine wheel (8) and shaft in the housing.7. Put housing in position on tool (B). 8. Install ring (13), bearing (11), sleeve (12), ring (10) and deflector (9) in the housing.
The oil hole in bearing (11) must be open and clean.
9. Install the seal rings on sleeve (15). Install sleeve insert (14). 10. Install insert in the housing and install snap ring (17).11. Install compressor wheel (16) on shaft. 12. Put clean engine oil on the threads of the shaft. Install the nut (18) and tighten it to a torque of 15 1 lb.ft. (20.3 1.4 N m).
When nut is tightened do not put a side force on the shaft.
13. Install shaft housing into the turbine housing. Install "V" clamp (21) and tighten clamp to a torque of 120 in. lb. (13.6 N m).14. Install cover (19) and "V" clamp (20). Tighten "V" clamp to a torque of 120 in. (13.6 N m).end by: a) install turbocharger
