Position engine to a 30° crank angle after ignition TDC of cylinder 1 |
Rotate engine at crankshaft in direction of engine rotation until marking for a 30° crank angle on the belt pulley/vibration damper (12) coincides with marking on the timing case cover (arrow).
The engine must not be turned back, otherwise the timing chain can skip and this can result in engine damage. |
