2. Lock the crankshaft with tool 116480 in the position of the piston of the first cylinder at TDC at the end of the compression stroke.
Attention:
- Do not allow the engine crankshaft to turn in the opposite direction.
- Before starting the engine, tool 116480 must be removed.
3. Remove the protective cap on the timing belt cover.
4. Lock the crankshaft using tool 115320 in the position of the piston of the 1st cylinder at TDC at the end of the compression stroke.
Note: The registration numbers must be visible on the top of the exhaust and intake camshafts (Ei A).
Note:
- The camshaft cams (E) of the intake valves of the 1st cylinder should be facing upward at an angle.
- The camshaft lobes (A) of the exhaust valves must be angled outward to the left.
Note: The marking on the exhaust camshaft sprocket (A) must match the marking on the exhaust camshaft sprocket (A).
Note: If the markings do not match, the exhaust camshaft must be removed.
