        • Loss of engine power 
          1. → Do not use force when fitting the staking tool.
          2. → Make sure that the gap is equal on both sides.
          3. → When inserting the staking tools, do not use force to turn the camshafts against any resistance.
          4. → The engine must be exactly at top dead centre.
          5. → The opposite cylinder must be at ignition TDC.
  11. Remove staking tools, perform two revolutions of the engine and check the timing again.

    1. 12.1  Fit T90001 - counter-hold tool-3-  and T90002 - counter-hold tool-4-  on the exhaust camshaft actuator -1-  .
    2. 12.2  Support T90002 - counter-hold tool-4-  on the intake camshaft actuator -2-  .

      Turn the crankshaft slightly to do this if necessary. (Only in direction of rotation of engine) 

    3. 12.3  Tighten exhaust camshaft actuator -1-  .

      Final tightening + 35° 

    4. 12.4  Fit T90001 - counter-hold tool-3-  and T90002 - counter-hold tool-4-  on the intake camshaft actuator -2-  .
