14 Turn left camshaft into <strong>basic</strong> <strong>position</strong> The <strong>basic</strong> <strong>position</strong> <strong>of</strong> <strong>the</strong> camshaft is only<br />
correct if <strong>the</strong> retaining device (5) can be<br />
installed free <strong>of</strong> stress at <strong>the</strong> left cylinder<br />
head. The marking (A) <strong>of</strong> <strong>the</strong> camshaft<br />
bearing cap (2) must be aligned with <strong>the</strong><br />
marking (B) <strong>of</strong> <strong>the</strong> camshaft (3).<br />
At 30° after ignition TDC at cylinder 1 it is<br />
possible to rotate <strong>the</strong> camshaft without <strong>the</strong><br />
valves touching <strong>the</strong> pistons.<br />
