2. A cut in a back plate
A. A new belt, a natyazhitel without tags
B. A new belt, a natyazhitel with tags
C. An old belt, a natyazhitel without tags
D. An old belt, a natyazhitel with tags

PERFORMANCE ORDER
1. Carefully clean asterisks of cranked and distributive shaft. Check combination of tags of asterisks of camshafts with tags on covers of bearings, combination of a tag of an asterisk of a bent shaft with a cut in a casing of the oil pump (see rice. Combination of synchronizing tags).
2. Put on a belt asterisks.
3. Weaken a bolt of a natyazhitel and turn the lever of a natyazhitel counterclockwise against the stop. Tighten a bolt of a natyazhitel.
4. Check whether synchronizing tags are combined.
5. Turn a bent shaft on two whole revolutions.
6. Check tags 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 to a cut or to a tag of "NEW" (see rice. 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 has to be directed to 4 mm more to the left of a cut or has to indicate a tag of "USED" (see rice. An arrangement of the index of a natyazhitel concerning a cut in a back plate).
