Note.
- Necessary special devices, control and measuring instruments, as well as auxiliary means:
- Adapter (adapter) for the "T10170" clock type indicator.
- Camshaft position lock "T10171" or "T10171A".
- Clamping device "T10172".
- Counter support -T30004 (3415)-.
- Fixing pin "T40011".
- Hourly deviation indicator.
1. Remove the cylinder head cover and air filter.
2. Remove the camshaft covers.
3. Remove the timing chain cover.
4. To turn the crankshaft, install the bearing sleeve, crankshaft pulley (2) and fastening screw (3) as shown in the figure below. Tighten the crankshaft screw (use the counter support "T30004" for this).
5. Remove the ignition coil of the 1st cylinder.
6. Screw the adapter for the dial indicator "T10170" into place of the spark plug until it stops.
7. Install the dial indicator (A) with the extension -T10170/1- until it stops, clamp it with the clamping nut (arrow), as shown in the figure below.
8. Turn the crankshaft in the direction of engine shaft rotation until the piston of the 1st cylinder is at TDC. Mark the position on the deviation indicator using a small arrow.
9. Turn the crankshaft 45° against the direction of rotation of the engine shaft.
10. Move the tensioner bar (1) towards the loosening side (in the direction of the arrow), as shown in the figure below, fix the tensioner plunger using the locking mandrel "T40011".
11. Using a suitable felt-tip pen, mark the direction of movement of the camshaft drive chain (3).
12. Unscrew the mounting bolts (2) and remove the intake camshaft drive sprocket (1) with the camshaft drive chain (3), as shown in the figure below. Use the counter support "T10172" for this.
13. Reinstall the intake camshaft drive sprocket (1).
14. Replace the mounting bolts (2). Tighten the mounting bolts (2) to a tightening torque of 50 Nm; use (counter support "T10172").

15. Turn the camshafts that operate the intake and exhaust valves until the camshaft locking tool "T10171" or "T10171A" can be inserted into the holes in the camshafts as far as it will go. The locking mandrels (arrows 1) must fit into the holes (arrows 2). The inscription "TOP" (arrow 3) must be legible from above.
Note: The camshafts must not be displaced axially during screwing.
16. To fix the locking tool for camshafts "T10171" or "T10171A" screw the M6 screw (arrow) shown in the figure below by hand; without tightening it further.
17. Loosen the bolts securing the sprockets on the camshafts. It is necessary to use the counter support "T10172".
Caution: The camshaft locking tool "T10171" or "T10171A" must not be used as a holding tool.
18. Remove the camshaft chain sprocket.
19. Place the camshaft drive chain onto the sprockets on the camshafts (while maintaining the direction of movement of the chain) and reinstall the removed sprocket.
20. Tighten the camshaft mounting bolts to such an extent that it is possible to move the sprockets relative to the camshafts.
21. Tighten the camshaft drive chain by pulling out the locking mandrel "T40011".
22. Turn the crankshaft to the TDC position of the piston of the 1st cylinder. Permissible deviation from the TDC of the piston of the 1st cylinder:±0.01 mm
Note: If the crankshaft rotates more than 0.01 mm past TDC, then turn the crankshaft back approximately 45°. Then turn it off in the direction of engine shaft rotation to the TDC position of cylinder 1.
23. Using the counter support "T10172", support the chain drive sprockets on the camshafts (1) and (4) in this position and tighten the mounting bolts (2) with a tightening torque of 50 Nm, as shown in the figure below.
Note: When tightening the camshaft bolts, the crankshaft must not be allowed to turn and the camshaft drive chain (3) must remain taut.
24. Remove the camshaft locking tool "T10171" or "T10171A".
25. Turn the crankshaft 2 revolutions in the direction of engine shaft rotation to the TDC position of the 1st cylinder. The permissible deviation from the TDC of the piston of the 1st cylinder is ±0.01 mm.
26. Insert the camshaft locking tool "T10171" or "T10171A" into the holes in the camshafts until it stops. If the camshaft locking tool "T10171" or "T10171A" cannot be inserted, the adjustment must be repeated.
27. Remove the locking tool for camshafts "T10171" or "T10171A", hold the chain sprockets on the camshafts using the counter support "T10172" and use a wrench to tighten the bolts (2) an additional ¼ turn (90°).
28. Turn the crankshaft in the direction of rotation of the engine shaft another 2 turns to the TDC position of the piston of the 1st cylinder. Permissible deviation from the TDC of the piston of the 1st cylinder: ±0.01 mm.
29. Insert the camshaft locking tool "T10171" or "T10171A" into the holes in the camshafts until it stops.
30. Further installation is carried out in the reverse order of removal.
Install the timing chain housing.
Replace the camshaft cover sealing rings and lubricate them with oil before installation
