20. Remove covers of a gas-distributing belt.
21. Unscrew a bolt of an asterisk of a cranked shaft.
22. Remove a persistent flange of a belt.
23. Turn a cranked shaft so that to combine sinkhronizatsionny labels of asterisks of cranked and distributive shaft (SOHC).
24. Turn a cranked shaft so that to combine sinkhronizatsionny labels of asterisks of cranked and distributive shaft (1,8 l of DOHC).
25. Note the direction of rotation of a belt.
26. Weaken a natyazhitel of a belt and remove a belt.
27. If it is necessary for you to remove asterisks of camshafts for replacement of epiploons, uncover valves, unscrew bolts of asterisks and remove asterisks.

Check

PERFORMANCE ORDER
1. Remove intermediate pulleys and examine their bearings.
2. If the belt was strongly damaged, clean asterisks from the remains which have got stuck in them of a belt.
3. Examine a belt on existence of the burst or absent teeth. If a teeth of a belt is torn off or has cracks, that, possibly, jams camshafts or shaft of oil or water pumps.
4. If the belt is strongly worn-out or in it there are cracks, it is necessary to check asterisks of shaft.
5. If the lateral surface of a belt is damaged, it is necessary to check a persistent flange and installation of asterisks.
6. If necessary replace a belt and correct malfunctions.

Installation

PERFORMANCE ORDER
1. Clean area of an arrangement of a belt.
2. Establish intermediate pulleys and a pulley of a natyazhitel.
3. Establish asterisks of shaft and tighten bolts.
4. Combine sinkhronizatsionny labels of asterisks of cranked and distributive shaft (SOHC).
5. Combine sinkhronizatsionny labels of asterisks of cranked and distributive shaft (1,8 l of DOHC).
6. Put on a belt asterisks.
Models in volume of 1,6 l
7. Establish a persistent flange of a belt and a bolt of an asterisk of a cranked shaft.
8. Turn a cranked shaft on two complete revolutions and combine sinkhronizatsionny labels.
9. Check, that labels of an asterisk of a camshaft were correctly combined with labels on a head of cylinders.
10. Weaken a bolt of a pulley of a natyazhitel that the belt stretched.
11. Tighten a bolt of a pulley of a natyazhitel.
