See Compressor Wheel Clearance for the correct shim thickness to use.b. Put compressor wheel on the shaft.c. Put a small amount of clean engine oil on the threads.d. Tighten the nut to 14 to 17 N m (125 to 150 lb in).
Do not bend or add stress to the shaft when nut is loosened or tightened.
e. Remove nut from shaft and apply 6V1541 Quick Cure Primer on the threads of the shaft and nut followed by application of 9S3265 Retaining Compound.f. Tighten nut to 4 N m (30 lb in).g. Tighten nut more as follows: For 99.0 mm (3.90 in) diameter compressor wheels, tighten the nut an additional 90°.For 86.4 mm (3.40 in) diameter compressor wheels, tighten the nut an additional 60°.(7) Shims.

a. Remove the compressor wheel from the cartridge group and place the wheel in the compressor housing. Center the wheel in the housing.b. Measure the distance from the compressor housing mounting face to the compressor wheel seating face. Measure four places at approximately 90° increments. This is dimension "A" (Fig. 1).c. Assemble the cartridge group complete except for the compressor wheel and shims. Hold the turbine wheel-shaft assembly toward the compressor end against the thrust bearing. Measure the distance from the bearing housing end face to the flinger sleeve. This is dimension "B" (Fig. 2).d. Measure the distance from the bearing housing end face to the compressor housing mounting face of the bearing housing. This is dimension "C" (Fig. 2).e. Shim thickness is C-B-A +0.23 to 0.28 mm (C-B-A +.009 to .011 in). This is the thickness of the shims to be installed between the flinger sleeve and compressor wheel.f. Shims to be of uniform thickness and free of burrs or other imperfections. Shim thickness should total 0.13 to 0.41 mm (.005 to .016 in) and consist of one or two shims selected from those specified in Step g. All measurements to be taken with dry (no lubrication) turbocharger.g. Thickness of shims: 4W7362 Shim ... 0.076 mm (.003 in)4W7357 Shim ... 0.127 mm (.005 in)4W7358 Shim ... 0.152 mm (.006 in)4W7359 Shim ... 0.178 mm (.007 in)4W7360 Shim ... 0.203 mm (.008 in)4W7361 Shim ... 0.229 mm (.009 in)4W7363 Shim ... 0.254 mm (.010 in)
