Page. An old belt, a natyazhitel without labels
D. An old belt, a natyazhitel with labels

PERFORMANCE ORDER
1. Carefully clean asterisks of cranked and distributive shaft. Check combination of labels of asterisks of camshafts with labels on covers of bearings, combination of a label of an asterisk of a cranked shaft with a cut in a casing of the oil pump (see fig. Combination of sinkhronizatsionny labels).
2. Put on a belt asterisks.
3. Weaken a bolt of a natyazhitel and turn the lever of a natyazhitel counter-clockwise against the stop. Tighten a bolt of a natyazhitel.
4. Check, whether sinkhronizatsionny labels are combined.
5. Turn a cranked shaft on two complete revolutions.
6. Check labels and again weaken a bolt of a natyazhitel.
7. If you established a new gas-distributing belt, adjust a natyazhitel so that his index was directed on a cut or on "NEW" label (see fig. An arrangement of the index of a natyazhitel concerning a cut in a back plate) also tighten a bolt.
8. If you established an old belt, the index of a natyazhitel should be directed on 4 mm more to the left of a cut or should point to "USED" label (see fig. An arrangement of the index of a natyazhitel concerning a cut in a back plate).
9. Establish the remained details.
