Note: Do not interchange the thrust bearings of the inlet and exhaust camshafts during assembly; observe identification markings.
29. Insert three thrust bearings and one housing -arrows- for the bearing sleeve of the camshafts together with the guide rail for the timing chain.
30. Insert eight housing screws (Torx): six M6 x 35 -1- and two M6 x 40 -2- for camshaft bearing and guide rail. Tighten screws evenly and just
finger-tight.

Note: Position crankshaft above the pulley or vibration balancer before final adjustment of the timing to the TDC marking.
Note: Before final tightening (torque angle) of the central screw, the special tool adjusting gauge 9686 must be removed.
