PERFORMANCE ORDER
1. Remove a radiator.
2. Remove the pump of the amplifier of a steering.
3. Remove the forward stabilizer of cross-section stability.
4. Remove the oil pallet.
5. Remove an auxiliary driving belt.
6. Unscrew bolts and nuts and remove elements of the mechanism of a tension of an auxiliary driving belt (see fig. Elements of the mechanism of a tension of an auxiliary driving belt with the rack of the shock-absorber located under the mechanism of a tension, Elements of the mechanism of a tension of an auxiliary driving belt with the rack of the shock-absorber located over the mechanism of a tension, the Detail of the mechanism of a tension of an auxiliary driving belt without a shock-absorber rack).
7. On models with the rack of the shock-absorber established under the mechanism of a tension, unscrew a bolt, the fixing bottom end of a rack of the shock-absorber, and a bolt, a fixing arm of the mechanism of a tension, and in the last turn unscrew the central bolt of the mechanism of a tension. Remove details of the mechanism of a tension from the engine.
8. On models with the rack of the shock-absorber established over the mechanism of a tension of an auxiliary driving belt, unscrew a pulley of the pump of the amplifier of a steering, then a pulley of the mechanism of a tension. Unscrew a shock-absorber rack from an arm of the mechanism of a tension. Unscrew the second end of a rack амортизато ра from a generator arm. Fix from a provorachivaniye a bolt, the fixing knot of the mechanism of a tension to an arm of the pump of the amplifier of a steering and unscrew a nut from a bolt. Unscrew two bolts, fixing an arm of the mechanism of a tension to a cover of a driving chain. Unscrew the central bolt of the mechanism of a tension, then remove knot of the mechanism of a tension from the engine.
9. On models without a rack of the shock-absorber unscrew a bolt and remove the tension mechanism.
10. Remove a pulley of a cranked shaft from a nave.
11. Unscrew bolts and remove the water pump.
12. Remove a casing of the air filter.
13. Remove the ignition distributor.
14. At existence unscrew bolts of fastening of the pump of system of a being self-leveled back suspension bracket and, without disconnecting from the pump hydraulic hoses, move the pump aside.
15. Uncover heads of the block of cylinders.
16. Unscrew three bolts of fastening of the top part of a cover of a driving chain to a head of the block of cylinders (see fig. An arrangement of bolts of fastening of the top part of a cover of a driving chain to a head of the block of cylinders).
17. At existence unscrew three bolts and remove an arm of fastening of the compressor of central air of air and the pump of the amplifier of a steering (see fig. Arrangement of bolts of fastening of an arm of fastening of central air of air and pump of the amplifier of a steering).
18. On models with system кондициониро vaniye of air unscrew bolts of fastening of the compressor of the conditioner and, without disconnecting from it hoses, move the compressor aside.
19. Remove the generator together with an arm.
20. Remove the generator together with an arm.
21. Unscrew two bolts, fixing a maslopriyemny pipe of the oil pump to a cover of the radical bearing and a nut, a fixing pipe to an arm and take an arm.
22. Unscrew other bolts, fixing a cover of a driving chain to the block of cylinders of the engine. Note an arrangement of bolts as bolts have different length. Uncover a driving chain directing pins together with a tube of a maslopriyemnik (see fig. An arrangement of bolts of fastening of a cover of a driving chain to the block of cylinders of the engine).
23. Remove the rasporny plug from a forward part of a cranked shaft.
