b. Put a small amount of 9S3265 Retaining Compound on the nut and shaft threads.
| NOTICE |
|---|
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. |
c. Put a small amount of lubricant such as Lubriplate on the nut seat area on the compressor. Do not put lubricant on the threads.
| NOTICE |
|---|
Do not bend or add stress to the shaft when the nut is tightened. |
d. Tighten the compressor wheel retainer nut to a torque of 30 ± 3 N·m (22 ± 2 lb ft).
18. Put the cartridge housing in a vise as shown. Check the shaft end play with Tool (E). The end play must be 0.114 ± 0.038 mm (.0045 ± .0015 in). If the shaft end play is not the correct dimension, the inside parts of the cartridge housing must be check for too much wear. See Turbocharger (F452, F552 and F555) in Specifications section.
19. Install the turbine housing on Tool (F). Put the cartridge assembly in position in the turbine housing. Make sure the marks on the housings are in alignment with each other. Put 5P3931 Anti-Seize Compound on the threads of the "V" clamp that holds the cartridge assembly to the turbine housing. Install the "V" clamp, and tighten the bolt to a torque of 14 ± 3 N·m (10 ± 2 lb ft).
20. Install the compressor housing to the cartridge assembly. Install the "V" clamp that holds the compressor housing to the cartridge housing and tighten the bolt to a torque of 14 ± 3 N·m (10 ± 2 lb ft).
