Fitting
Installation is carried out in the reverse order. But note the following:
  Note
t  Always replace gaskets, O-rings and self-locking nuts.
t  Charge the turbocharger with engine oil using the connection sleeve of the oil supply pipe.
t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue.
–  Fit the gear mechanism to the gearbox and adjust it → Rep. Gr.34.
–  Install the front exhaust section with the particle filter → Chapter.
–  Align exhaust system without tension → Chapter
–  Mount the right half-shaft → Rep. Gr.40.
–  Fit the battery → Rep. Gr.27.
–  Check oil level . → Chapter.
  Note
After fitting the turbocharger, allow the engine to run at idle for about 1 minute, without accelerating; this will lubricate the turbocharger.
