Do put side force on the shaft when tightening or removing the nut that holds the compressor wheel in position. Use a universal drive socket when tightening.
a. With the compressor wheel on the shaft, put a small amount of clean engine oil on the turbine shaft threads and the compressor wheel face that contact with the nut.b. Install the nut, and tighten it to a torque of 14 to 17 N m (125 to 150 lb in) to push the compressor wheel on to the shaft.c. Remove the nut from the shaft. Apply 6V1541 Quick Cure Primer on the threads of the shaft and the nut.d. Put 9S3265 Retaining Compound on the threads of the shaft and the nut.
Do not let the retaining compound get into the compressor wheel bore or on the shaft, because it can make removal of the compressor wheel difficult during future turbocharger disassembly.
e. Install the nut, and tighten it to a torque of 4 N m (30 lb in). Then tighten the nut an additional 75° of rotation.(8) Thickness of each thrust ring ... 2.553 0.013 mm (.1005 .0005 in)(9) Torque for four nuts (put 5P3931 Anti-Seize Compound on threads) ... 55 5 N m (40 4 lb ft)
