1 | Turn engine with a socket at center bolt (13) in direction of engine rotation, until the bore (15) on belt pulley/vibration damper (12) is aligned with the housing bore (11). |
2 | Check position of the camshaft through the openings of the position sensors of the camshafts based on the alignment edges (5a, 6a). |
3 | Mark of bore (15) on the belt pulley (12) with drift (2). |
Do not turn engine against direction of engine rotation. |
If the alignment edges (5a, 6a) stand as represented, then engine stands at 40° after ignition TDC of cylinder 1. |
If the alignment edges (5a, 6a) stand as represented, then engine stands at 40° after overlap TDC of cylinder 1. |
A complete crankshaft revolution (360°) lies between 40° after 1st cylinder TDC and 40° after 1st cylinder TDC at valve overlap. |
