Unscrew the compressor wheel’s shaft nut. Use a Tbar together with a universal joint and sleeve so that the turbine wheel shaft is not unevenly loaded.
Scribe in markings between the compressor housing (1), the cover (4), bearing housing (11), and turbine housing (14).
NOTE! The nut is secured with Loctite. If it is tight heat with hot-air gun to max. 130 °C (266 °F).
2 Remove the compressor housing: Tap if necessary with soft mallet so that the parts separate. NOTE! Observe care when removing the housings so that the compressor and turbine wheels are not damaged. These parts cannot be repaired and must be replaced if damaged.
3 Remove the turbine housing. Heat up the housing somewhat with a hot-air gun if is tight. 4 Place the turbine wheel hub on suitable cap wrench as per fig.
6 Mark up the position of the compressor wheel in relation to the shaft. Heat the compressor wheel in the same way to max. 130 °C (266 °F). Carefully press out the shaft with a press tool or pillar drill. NOTE! The heat shield (12) must be held centred to the bearing housing when the shaft is pressed out.
