30. Insert eight housing screws (Torx): six M6 35 -1- and two M6 40 -2- for camshaft bearing and guide rail. Tighten screws evenly and just
finger-tight.
Timing for side 1 - 3
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.
31. Final timing adjustment for cylinder bank 1 - 3 is analogous to that for cylinder bank - 6.
32. Fit chain tensioner for side 1 -3 (hexagon a/f 32) before turning crankshaft to the TDC mark. Fit chain tensioner with new sealing ring and tighten.
Tightening Torque: 59 ft. lb.
After adjusting the timing, this should be re-checked.
33. Turn the engine 360° at the crankshaft and fix at the TDC mark. Check camshaft position of cylinder bank -6 using the adjusting gauge 9686. Then
turn a further 360° and check the camshaft position of cylinder bank 1 - 3.
