Pic. 5.20. Camshafts:
1. Exhaust camshaft,
2. Intake camshaft,
3. Locking pin,
4. Cylinder head cover,
5. Intake camshaft pulley,
6. Pulley for exhaust camshaft,
7. Guide pins,
8. Camshaft bearing cap,
9, 12. Bolt,
10. Chain tensioner,
11. Seal,
A. Hole in the bearing cap,
B. Pulley hole.
2. Remove the cylinder head cover 4.
3. Set the piston of the first cylinder to the TDC position.
4. Block the flywheel with a lock.
5. Lock the intake camshaft 2. Insert pin 3 through the hole in the first camshaft bearing cap into hole A in the intake camshaft pulley 5.
6. Remove the timing chain tensioner 10.
7. Remove the front cylinder head cover, upper sliding arm.
8. Mark the location of the intake camshaft pulley 5 relative to the timing chain.
9. Unscrew the pulley of the final camshaft 6.
10. Turn off bolts of fastening of covers of 8 bearings of camshafts. First, unscrew the bolts securing covers 1, 3, 5, 6, 8 and 10 (arrows) (see fig.5.21). Then loosen the cap screws 2, 4, 7 and 9 (arrows) (see fig.5.22). Remove the camshaft bearing caps (arrows).
Pic. 5.21. Unscrew the bolts of the covers 1, 3, 5, 6, 8 and 10 (arrows).
Pic. 5.22. Unscrew the bolts of the covers 2, 4, 7 and 9 (arrows).
11. Remove camshafts 2 and 1.
Installation
12. Install camshafts 2 and 1 so that the two holes B on the pulleys 5 and 6 are located one opposite the other, and the marks on the camshafts 2 and 1 (arrows) and on the bearing caps 8 were aligned.
13. Remove the camshaft retainer.
14. Set the piston of the first cylinder to the position 30°before TDC. Marks on bearing cap 8 (arrows) should match.
15. Install bearing caps 8 in the reverse order of removal. Each lid has its own label (see fig.5.23). Marking of bearings of the left camshaft, starting from the front: E1-E5. Marking of bearings of the right camshaft, starting from the front: A1-A5.

11. Seal,
A. Hole in the bearing cap,
B. Pulley hole.
16. Set the piston of the first cylinder to the TDC position.
17. Block the inlet camshaft 2. The piston of the first cylinder must be in the TDC position.
18. Install the exhaust camshaft pulley 6 with the timing chain on it. Replace bolts 9 fastening the pulley. Pay attention to the correct installation of the guide pins 7.
19. Install the chain tensioner 10. Replace the seal 11.
20. Check the basic position of camshafts 1 and 2. If necessary, after checking, install the basic position of the camshafts.
21. Install the cylinder head cover 4.
22. Install nozzles.
23. Start the engine and check for leaks in the fuel system. Read the fault memory and clear it.
