📋 Procedure

1. Remove timing chain from inlet camshaft .
2. Check "“TDC”" position of camshafts:
3. Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
4. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
5. Loosen bearing cap bolts in the sequence (12 ... 1). [Note: Make sure you do not damage the roller rocker fingers and hydraulic compensation elements when removing the camshafts.]

6. Carefully detach bearing caps and camshafts.
7. Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
8. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
9. Fit camshaft bearing pedestals "“I, II and III”" on cylinder head.
10. Fit camshaft bearing pedestal "“IV”" on cylinder head.
11. Check that bearing pedestals are positioned correctly:
12. Insert camshafts in bearing pedestals in "“TDC”" position.
13. Fit matching bearing caps on bearing pedestals.
14. Wrap one cable tie (arrows) on each side around bearing pedestal and bearing cap and secure. [Note: The cable ties help to keep the camshafts and camshaft bearings straight when they are tightened.]
