7	Position engine to 40° after ignition TDC of cylinder 1	Engine must not be cranked back. Rotate engine at crankshaft in direction of rotation until 40° marking on belt pulley/ vibration damper is aligned with marking on timing case cover. Grooves (1) on the camshafts must point toward the inner V.
8	Check basic position of camshafts	Place locating plates (2) flush on the right and left cylinder heads, and fit into the grooves (1) of the camshafts.	Figure Figure
	If this is not possible: ↓
	Set the basic position of camshafts	AR05.20-P-6020AU
9	Inspect basic position of the balancing shaft	The hole (3) at the rear correctional weight (4) must align with the hole in the crankcase. Fix hole with a pin or suitable drift (Ø 8.40 to 8.55 mm). If the hole (3) at the rear of the correctional weight (4) is aligned with the hole in the crankcase, then, the pin at the crankcase (A) and the notch in the front correctional weight (B) must point toward each other. The pin (A) and the notch (B) can be seen through the left timing case recess at a depth of about 22 cm from the cylinder head cover separating surface. If the markings of the front and rear balance shaft do not match, the balance shaft must be replaced:↓ Remove balancing shaft	AR03.20-P-1000A
