Assemble

The balance marks must be aligned to make sure the wheel and shaft assembly is balanced.

1. Install the piston ring and lubricate the groove with engine oil.

Turbine Shaft/heat Shield To Bearing Housing:

2. Install the heat shield.
3. Clamp a socket in a soft jawed vice and position the shaft in the socket.

Beveled Face Of Inner Retainer Ring:

4. Install the inner retainer rings. The beveled face must be towards the bearing.
5. Lubricate the turbocharger bearing with engine oil and install the bearings in the housing.

Beveled Face Of Outer Retainer Ring:

6. Install the outer retainer ring. The beveled face must be towards the bearings.
7. Assemble the turbine shaft and heat shield to the bearing housing. Rotating the housing as you press downward will assist in properly seating the piston ring.
8. Install the thrust collar. Align the balance mark with the balance mark on the shaft. Mark the top surface with a marker pen so alignment can be verified after installing the thrust bearing.
9. Lubricate the thrust bearing with engine oil and install it on the housing. Tighten the torx bolts to 4.5 Nm (40 in lb) torque.
10. Install the oil baffle. Check the balance mark alignment.

Piston Ring Type Seal:

11. Install the piston ring type seal on the oil slinger.
12. Mark the top surface of the oil slinger line with the balance mark.
13. Lubricate the oil slinger with engine oil and install it into the diffuser.
14. Install the 0-ring into the diffuser.

Align Balance Marks - Shaft And Oil Slinger:

15. Install the diffuser. Align the balance marks on the shaft and the oil slinger.

Align Balance Marks - Impeller:

16. Align the balance mark and install the impeller. Be careful not to move the bearing housing.
17. Do not allow the impeller to turn when installing the nut. The impeller nut and the shaft have LEFT hand threads. Tighten the nut to 14 Nm (129 in lb) torque.

Bearing Housing Assembly/Turbine Housing:

18. Install the bearing housing assembly into the turbine housing.

Bearing Housing Assembly/Turbine Housing:

19. Align the scribe marks.
20. Apply anti-seize compound to the bolt threads.

Install Clamp Plates/Lock Plates:

21. Install the clamp plates, lock plates and bolts. Tighten the bolts to 11.3 Nm (100 in lb) torque.

Diffuser And Lockplate:

22. Install the lock plates and bolts into the diffuser.
23. After tightening the bolts to 5.7 Nm (50 in lb) torque, bend the lockplate tabs to lock the bolts. Be sure the scribe marks are aligned.

Endplay/Radial Clearance Of Shaft:

24. Measure the end play. For turbo charger with a serial number before 840638 the end play should be 0.102-0.152 mm (0.004-0.006 inch). For turbocharger with a serial number of 840638 and after the end play should be 0.026-0.076 mm (0.001- 0.003 inch).
25. Measure radial clearance of the shaft. The clearance should be 0.300-0.460 mm (0.012- 0.018 inch).
26. Install the square cut 0-ring.
27. Be sure the scribe marks are aligned. Install the compressor housing and V-band clamp. Apply anti-seize compound to the V-band bolt threads. Tighten the clamp to 8 Nm (72 in lb) torque. Tap against the clamp on 4 places around its circumference. Again tighten the clamp to 8 Nm (72 in lb) torque.
