Removal

PERFORMANCE ORDER
1. Disconnect a wire of the minus plug of the accumulator.
2. Disconnect an airintaking branch pipe and the air filter.
3. Remove external covers of a gas-distributing belt. Remove the pump of the hydraulic booster of steering if it is established.
4. Take off a wedge-shaped belt of the generator.
5. Turn a bent shaft so that the N1 piston was installed in the top dead point. If necessary, temporarily put on a pulley of a bent shaft to combine synchronizing tags.
6. Insert a suitable core into a tension indicator lever opening, tighten the lever against the stop clockwise and stop the lever, having inserted a core into the corresponding opening in a basic plate of the indicator of a tension
7. Weaken three fixing bolts of the pump of the cooling system. Turn the pump so that to weaken a tension of a gas-distributing belt.
8. Take off a gas-distributing belt. Take the correct adjusting provision of a belt into account.

Installation

PERFORMANCE ORDER
1. Make sure that the N1 piston still is in VMT
2. Put on a gas-distributing belt asterisks.
3. Adjust a belt tension.
4. Establish external covers.
5. If necessary install the pump a driving belt of the pump of the power steering.
6. Install the air filter and an airintaking branch pipe.
7. Connect a wire of the minus plug of the accumulator.

Adjustment

PERFORMANCE ORDER
1. Remove external covers of a gas-distributing belt.
2. Install the N1 piston in VMT.
3. That it was easier for you to scroll a bent shaft, unscrew spark plugs.
4. Weaken three fixing bolts of the pump of the cooling system.
5. Turn the cooling system pump clockwise. The tension of a belt will increase. Continue to turn the pump until the lever of the indicator of a tension does not turn clockwise against the stop.
6. Tighten fixing bolts of the pump of the cooling system.
7. Turn a bent shaft clockwise on two whole revolutions until the N1 piston is installed in VMT again.
8. Accurately turn the cooling system pump counterclockwise to weaken a belt and that the index of the indicator of a tension (1) was established in the middle of V-shaped dredging (2) in a basic plate of the indicator. Tighten fixing bolts of the pump till the necessary moment of an inhaling.
9. Turn a bent shaft clockwise on two turns and check that the index of the indicator of a tension was still located in the middle of V - figurative dredging in a basic plate of the indicator.
10. After end, twist spark plugs on places and establish external covers of a gas-distributing belt.
