4. Take off a gas-distributing belt and note its direction of rotation.
5. Carefully examine a belt on existence of wear and damages, if necessary replace it.

Installation

Combination of synchronizing tags

1. Tags of asterisks of camshafts

2. Tags on covers of bearings

3. Combination of a tag of an asterisk of a bent shaft with a cut in a casing of the oil pump

1. Index of a natyazhitel
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).
9. Establish the remained details.
