8. TURBOCHARGER (5) Compressor impeller installation 1) Fit compressor impeller (18) onto turbine shaft (1). 2) Set a box spanner (10 mm) on the turbine side end of turbine shaft (1), and tighten shaft end nut (19). Note: Since the shaft end nut has left- handed screw, pay attention to the tightening direction. Tightening torque: 2.0 ± 0.2 Nm {20 ± 2 kgcm} (6) Turbine housing installation 1) Install bearing housing (15) on turbine housing (11) by aligning the match marks put before disassembly. Note: In case of part replacement, check the oil inlet and outlet positions and the exhaust gas inlet position before reassembly.
2) Install the turbine side keep plate and tighten M8 hexagon bolt (12). Tightening torque:285 ± 10 Nm {28 ± 1 kgm} (7) Compressor housing installation 1) Apply liquid gasket (Three Bond No.1207) on the compressor side flange of bearing housing (15). Note: See section (4)3) for the portion to be applied. Applying thickness: 0.1 – 0.2 mm 2) Check the mark and install the compressor housing (7)on the bearing housing (15). Note: When a part is replaced, confirm a position of an oil entrance and a posi- tion of an air exit, and assemble it. 3) Install the keep plate (10) on compressor side, and tighten M8 hexagon bolt (8).
Tightening torque:48 ± 5 Nm {4.7 ± 0.5 kgm} (8) Rotor play measurement See the inspection procedure in section 8.3.2 for the measurement method. If the rotor play does not satisfy the standard, reassembly is necessary since assembly error or use of a wrong part is conceivable. Service standard of rotor play in axial direc- tion RHB51 ........... 0.03 – 0.06 mm RHB31 ........... 0.022 – 0.053 mm Service standard of rotor play in radial direc- tion RHB51 ........... 0.08 – 0.13 mm RHB31 ........... 0.061 – 0.093 mm 8-18 82E-5 – 98E-5 SERIES
