2. Remove the intake chamber.
3. Remove the spark plugs.
4. Remove timing belt cover No.2.
5. Check the timing marks of the camshaft toothed pulley.
- a) Turn the crankshaft pulley and align its mark (notch) with the installation mark "0" on the timing belt cover No.1.
- b) If necessary, rotate the camshafts and align the timing marks as shown in the figure.
- If there is more than one tooth of the toothed pulley between the marks, re-install the marks according to point 7.
- If there is less than one tooth of the timing pulley between the marks, re-set the marks according to point 8.

6. Remove the cylinder head cover.
7. Adjust the timing marks of the camshaft toothed pulley.
- a) Remove the tensioner by unscrewing the two bolts.
- b) Remove the timing belt from the camshaft toothed pulleys.
- c) Align the timing marks on the camshafts and timing belt cover No.3 by turning the camshafts with a wrench.
- d) Reinstall the timing belt and check the tension between the crankshaft sprocket and the intake camshaft sprocket.
Note: Install the timing belt on a cold engine.
- d) Install the tensioner by tightening the two bolts (For the tensioner installation procedure, see page 41, item 12).
- Tightening torque - 21 Nm
- e) Slowly turn the crankshaft pulley two revolutions from TDC to TDC.
Note: Always turn the crankshaft pulley clockwise.
- g) Check that each pulley is aligned with the timing marks as shown in the figure.
- c) Using a feeler gauge, check the gap between the tensioner housing and the tension roller retainer.
- Nominal clearance - 1.80-2.20 mm
8. Check the valve timing.
- a) Using a wrench, turn and align the notches on the camshafts with the notches on the camshaft bearing caps.
- b) Turn the crankshaft pulley and align its mark (notch) with the installation mark "0" on the timing belt cover No.1.
- Alignment of marks ±2.4 mm
9. Adjusting the valve timing.
- a) Secure the camshafts with a wrench at the hexagonal section and loosen the toothed pulley mounting bolts.
Note: Do not tighten the timing belt when loosening the bolts.
- b) Check the alignment of the camshaft recesses with the recesses on the camshaft bearing caps.
- c) Using a magnetic rod, remove the dowel pins from the toothed pulleys as shown in the figure.
- d) Turn the crankshaft pulley and align its mark (notch) with the installation mark "0" on the timing belt cover No.1
- d) Select a hole for the pin and install the pin.
Note:
- If the holes are not aligned, turn the crankshaft slightly and insert the pin into the nearest hole.
- By selecting the next pin hole, the crankshaft can be rotated by 2°.
- By selecting a hole for the pin every other one, you can turn the crankshaft by 5°.
- e) Secure the camshafts with a wrench at the hexagonal section and tighten the toothed pulley mounting bolts.
- Tightening torque - 59 Nm
Note: Do not tension the timing belt when tightening the bolts.
- g) Slowly turn the crankshaft pulley two turns from TDC to TDC.
- c) Check the valve timing.
10. Install timing belt cover No.2.
11. Install the spark plugs.
12. Install the cylinder head cover
13 Install the intake chamber.
14. Install the generator.
