82E-5 – 98E-5 SERIES 8-11
8. TURBOCHARGER
8.4.2 Inspection before disassembly
1) Inspect the turbine wheel and compressor impeller for any undesirable contact and the rotor for smooth
rotation.
2) Measure the rotor play as described in section 8.3(2.2).
• Rotor axial play Wear limit: mm
• Rotor radial play Wear limit: mm
8.4.3 Disassembly
The mounting angles of the turbine housing, bearing housing and compressor housing are determined accord-
ing to its mounting state on the engine. Put match marks before starting disassembly.
Note: The number after each part is the one described in the structural drawing in 8.1(2).
(1) Compressor housing removal
1) Remove flanged hexagon bolt (8) and compressor side keep plate (10).
2) Remove compressor housing (7).
Note:
1) Liquid gasket is applied on the surface of compressor housing (7). where bearing housing (15) is
mounted.
2) When disassembling compressor housing (7), carefully operate so as not to damage the compres-
sor impeller.
(2) Compressor impeller removal
1) Set a box spanner (10mm) on the turbine side end of the turbine shaft, and remove shaft end nut (19).
Note: Pay attention to the loosening direction since the shaft end nut has left-handed screw.
2) Remove compressor impeller (18).
(3) Turbine housing removal
1) Remove hexagon nut (12) and turbine side keep plate (13).
2) Remove turbine housing (11).
(4) Turbine shaft extraction
1) Hold heat insulating plate (20) lightly with a hand, and extract turbine shaft (1).
Note: If the turbine shaft is hard to be extracted, tap the compressor side end of the shaft lightly with a
wooden hammer.
2) Remove heat insulating plate (20).
(5) Seal plate removal
1) Use the Torx driver and loosen M3 Torx T-type machine screw (17) for seal plate mounting.
2) Remove seal plate (4).
Note: Liquid gasket has been applied to the seal plate and bearing housing mounting surface.
3) Remove oil thrower (2) from the seal plate.
(6) Slide bearing and thrust bushing removal
1) Use the Torx driver and loosen the M3 Torx T-type machine screw for thrust bearing installation.
2) Use the bar (copper) and remove thrust bearing (6) and thrust bushing.
(7) Floating bearing removal
1) Use the stop ring pliers and remove circlip (16) from bearing housing (15).
2) Remove floating bearing (5) from bearing housing (15).
(8) Seal ring removal
1) Remove turbine side seal ring (3) from turbine shaft (1).
2) Remove compressor side seal ring (small) and compressor side seal ring (large) from oil thrower (2).
