Check

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Take off auxiliary driving belts and the air filter.
3. Remove the top casing of a gear belt.
4. Examine a gear belt on existence of damages and pollution. If necessary replace a belt.

Removal, installation and adjustment of a tension

PERFORMANCE ORDER
1. If you watch the corresponding description in subsection 4.4.5, then but consider that you do not need to weaken bolts of the water pump and to rotate the pump as the tension of a belt is regulated automatically.
2. Unscrew a bolt of a natyazhitel of a belt and turn the lever of a natyazhitel to weaken a belt tension. Record a natyazhitel in such situation, having tightened a bolt. Take off a gear belt.
3. Check that the ledge on a flange of the water pump was combined with the corresponding ledge on the block of cylinders. If necessary adjust position of the water pump (see rice. Installation of a gear belt).
4. Pull a gear belt, having weakened a bolt of a natyazhitel and having turned the lever of a natyazhitel counterclockwise against the stop. Tighten a bolt of a natyazhitel.
5. Turn a bent shaft on two whole revolutions and check that adjusting tags are combined with indexes.
6. Again weaken a bolt of a natyazhitel and turn the lever of a natyazhitel so that to combine the index of a natyazhitel and a cut in an arm of a natyazhitel (see rice. Automatic natyazhitel of a gear belt). Tighten a bolt of a natyazhitel.
