Removal Procedure
2. |
Set the crankshaft balancer in
the direction of the engine rotation to "1st cylinder TDC" (mark
1). |
|
Note: The right half
of the EN-6340 locking tool can be recognised by
the lettering "right", arrow, on the tool.
|
4. |

marking (4) on the intake camshaft position actuator adjuster does
not correspond to the groove of the EN-6340 locking
tool - left (1) during this process, but must be somewhat
above. |
• |

marking (3) on the exhaust camshaft position actuator adjuster must
correspond to the groove on EN-6340 locking tool -
right (2). |
|
5. |

pulley (2). |
15. |
Remove the tensioner bolt
(1). |
16. |
Remove the timing belt
tensioner (2). |
17. |
Remove the timing belt
(1). |
18. |
Stop the timing belt tensioner
(2). |
19. |
Remove the EN-652
flywheel holder to unlock the crankshaft. |
20. |
Turn the crankshaft 60°
(A) against the direction of engine rotation. |
21. |
Remove the 2 camshaft position
actuator adjuster closure bolts (1). |
|
Note: A second
technician is required.
|
22. |
Loosen the camshaft position
actuator adjuster bolts (2). |
|
Hold at the appropriate camshaft hexagon. |
23. |
Remove and DISCARD the
camshaft position actuator adjuster bolts (2) and the camshaft
position actuator adjuster (3). |
24. |
Align the camshafts
horizontally by the hexagon arrows, until the EN-6628-A
locking tool can be inserted in both camshafts. |
25. |
Insert the EN-6628-A
locking tool (1) into the camshafts. |
Installation Procedure
|
Note: Do not tighten
the camshaft adjuster bolts.
|
1. |
Install the camshaft position
actuator adjuster (3). |
2. |
Install NEW camshaft position
actuator adjuster bolts (2). |
|
Note: A second
technician is required.
|
3. |
Tighten the camshaft position
actuator adjuster bolts (2) in three passes: |
|
Hold at the appropriate camshaft hexagon. |
|
3.1 |
First pass tighten to
65 N·m (48 lb ft) . |
|
3.2 |
Second pass to
120° . |
4. |
Replace the camshaft position
actuator adjuster seal rings. |
5. |
Install the 2 camshaft
position actuator adjuster closure plugs (1) and tighten to
30 N·m (22 lb ft) . |
6. |
Remove the EN-6628-A
locking tool . |
7. |
Clean the timing belt
tensioner thread. |
8. |
Install the timing belt
tensioner (2) and tighten the NEW timing belt tensioner bolt (1) to
20 N·m (15 lb ft) . |
9. |
Clean the timing belt idler
pulley thread. |
10. |
Install the timing belt idler
pulley (2) and tighten the NEW bolt (1) to 25 N·m
(18 lb ft) . |
|
Note: The timing belt
drive gear and oil pump housing must align.
|
11. |
Turn the crankshaft in the
direction of engine rotation, by the crankshaft balancer bolt, to
cylinder 1 TDC of combustion stroke. |
12. |
