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 N•m (20 ± 2 kgf•cm)
(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 N•m (28 ± 1 kgf•cm)
(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 to 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 position 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 N•m (4.7 ± 0.5 kgf•cm)
(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 direction
RHF5 0.03 to 0.06 mm
RHB51 0.03 to 0.06 mm
RHB31 0.022 to 0.053 mm
Service standard of rotor play in radial direction
RHF5 0.08 to 0.13 mm
RHB51 0.08 to 0.13mm
RHB31 0.061 to 0.093mm
