9. Ensure the timing marks (1) are aligned vertically.
10. Install the J 39411 to lock the crankshaft in this position. If the engine is on a stand, an alternate method should be devised.
11. Route the secondary drive chain for the LH cylinder head over the inner row of intermediate shaft teeth.
IMPORTANT: The RE camshaft sprocket must contain the camshaft position sensor pick-up.
12. Route the secondary drive chain over the chain guide and install the exhaust camshaft sprocket to the chain such that the camshaft drive pin
engages the sprocket notch marked LE (left head exhaust). There should be no slack in the lower section of the chain and the camshaft drive pin
must be perpendicular to the cylinder head face.
13. Install the intake camshaft sprocket into the chain so that the sprocket notch marked LI (left head intake) engages the camshaft drive pin while the
pin remains perpendicular to the cylinder head face. A hex is cast into the camshafts behind the lobes for cylinder -1 (or -2, LH) so that an open
end wrench may be used to provide minor repositioning of the camshafts.
14. Loosely install the exhaust camshaft sprocket retainer bolt.
