Note.
- Necessary special devices, control and measuring devices, as well as auxiliary means:
- Adapter (adapter) for dial gauge -T10170-.
- Camshaft positioner -T10171- or -T10171A-.
- Clamping tool -T10172-.
- Counterholder -T30004 (3415) -.
- Locking pin -T40011-.
- Dial indicator.
1. Remove the cylinder head cover and air filter.
2. Remove the camshaft covers.
3. Remove the timing chain cover.
4. To rotate the crankshaft, put on the bearing sleeve, crankshaft pulley (2) and fixing screw (3), as shown in the figure below. The crankshaft screw should be tightened (use counterholder -T30004- for this).
5. Remove the ignition coil of the 1st cylinder.
6. Screw in adapter for dial gauge -T10170- until stop.
7. Install dial indicator (A) with extension -T10170/1- up to the stop, tighten it with a clamping nut (arrow), as shown in the figure below.
8. Turn the crankshaft in the direction of rotation of the engine shaft until the piston of the 1st cylinder is at TDC. Mark the position on the deviation indicator with a small arrow.
9. Rotate the crankshaft 45°against the direction of engine rotation.
10. Move the tensioner bar in the direction of weakening (1) (in the direction of the arrow), as shown in the figure below, secure the tensioner plunger with the locking mandrel -T40011-.
11. With a suitable felt-tip pen, mark the direction of movement of the camshaft drive chain (3).
12. Unscrew the fastening bolts (2) and remove the intake camshaft drive sprocket (1), with camshaft drive chain (3), as shown in the figure below. Use counterhold -T10172- for this.
13. Reinstall the intake camshaft drive sprocket (1).
14. Replace mounting bolts (2). Tighten the mounting bolts (2) with tightening torque 50 Nm; apply in this (counterholder -T10172-).
15. Turn the camshafts that actuate 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 they will go. Stop mandrels (arrows 1) should go into the holes (arrows 2). Need an inscription "TOR" (arrow 3) could be read from above.
Note. The camshafts must not be displaced during screwing in in the axial direction.
16. To fix the locking tool for camshafts -T10171- or -T10171A-, screw in the M6 screw by hand (arrow), shown in the figure below; without tightening it further.
17. Loosen the sprocket mounting bolts on the camshafts. Counterholder -T10172- must be used.
Attention. The camshaft locking tool -T10171- or -T10171A- must not be used as a support tool.
18. Remove the camshaft chain sprocket.
19. Put the camshaft drive chain on the sprockets on the camshafts (respecting the direction of chain movement) and install the removed asterisk again.
20. Screw in the camshaft mounting bolts to such an extent that the sprockets can move relative to the camshafts.
21. Tension camshaft timing chain by pulling out locking pin -T40011-.
22. Turn the crankshaft to the TDC position of the piston of the 1st cylinder. Permissible deviation from TDC of the piston of the 1st cylinder:±0.01 mm
Note. If the crankshaft rotates more than 0.01 mm beyond VDC, then rotate the crankshaft back approximately 45°. Then turn it off in the direction of rotation of the engine shaft to the TDC position of the 1st cylinder.
23. Use the counterhold -T10172- to support the chain 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 screws, the crankshaft must not turn and the camshaft drive chain (3) should remain taut.
24. Remove camshaft locking tool -T10171- or -T10171A-.
25. Turn the crankshaft 2 turns in the direction of rotation of the engine shaft to the TDC position of the 1st cylinder. 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 on the camshafts as far as it will go. If the camshaft locking tool T10171- or -T10171A- cannot be inserted, the adjustment must be repeated.
27. Remove the camshaft locking tool -T10171- or -T10171A-, hold the chain sprocket on the camshafts with a counterhold T10172- and tighten the bolts with a wrench (2) ¼ turn (90°).
28. Turn the crankshaft another 2 turns in the direction of rotation of the engine shaft to the TDC position of the piston of the 1st cylinder. Permissible deviation from 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 as far as they will go.
30. Further installation is carried out in the reverse order of removal.
Install the timing chain housing.
Replace the sealing rings of the camshaft covers and lubricate them with oil before proceeding with the installation
