- separate a shtekerny block of the switch of lamps of a backing;
- disconnect a "mass" cable from a transmission. Disconnect the pipeline of system of coupling for what remove a spring collar and release coupling. To Zakuporta open ends of pipelines;
- disconnect the hoses of cooling liquid going to a broad tank and a heater;
- if by the car the conditioner is established, separate a shtekerny block of electromagnetic coupling;
- weaken poliklinovy a belt as it will be described further;
- weaken bolts of fastening of wheels. Establish a forward part of the car on support and remove forward wheels;
- remove a forward suspension bracket of the right wheel:
- disconnect draft 1 (fig. 365) of the stabilizer of cross-section stability;
- disconnect a brake hose and remove an ABS sensor cable (shows frequency of rotation of a wheel) from the holder on an amortizatorny rack;
- unscrew a nut of a bolt of cross-section steering draft on a soshka of a wheel and remove the hinge by means of a stripper from a wheel soshka;
- unscrew in the lower part of a suspension bracket of a wheel two bolts and wring out the spherical hinge of a suspension bracket from the case of the bearing of a wheel (a rotary fist);
- perform the described operations and on the left side of the car;
- adhere steering drafts a wire as it is shown on fig. 366 , to both amortizatorny racks. Now unscrew a steering from a cross-section beam, and drafts remain to hang on a wire;
- turn off a balansirny suspension bracket from a transmission;
- substitute a jack with a suitable support under a cross-section beam, lift a jack so that it raised a cross-section beam, and unscrew it in the places shown on fig. 367 ;
- merge transmission oil. Clear a stopper, and then at once again screw it;
- remove from a transmission a shaft of a drive of the right wheel. At first unscrew the persistent bearing 1 (fig. 368) and after that extend a shaft in a place 2 of shlitsevy connection with a transmission.
Take a shaft of a drive of the left wheel by means of the inserted mount (fig. 369) .
Disconnect gear shifting cables from a transmission. The ends of cables are fixed by means of clamps. After removal of clamps take both cables in the direction up from their holders.
Unscrew three bolts (fig. 370) and separate a reception pipe from a catalyst flange.
Disconnect an exhaust pipe from a turbokompressor (4 bolts).
Disconnect a hose from the heating pipeline (hose connection).
Disconnect hoses from a turbokompressor 1 (fig. 371) and a vacuum box 2 and release them from hose fastenings.
Turn on the holder of the pipeline of the pump of the hydraulic booster of a steering (it is located nearby from a pulley on cranked to a shaft). Unscrew a pulley of a drive of the pump of the hydraulic booster. To fix a pulley in motionless situation, insert a suitable face six-sided key into an internal part of a shaft of the pump.
Unscrew bolts of fastening of the pump of the hydraulic booster of a steering (one of bolts is located in its lower part), remove the pump, take him aside and adhere a wire.
If on the car the conditioner is established, remove the compressor. At first turn by means of a wrench 1 (fig. 372) a tension roller of a driving belt in the direction shown by an arrow so that the driving belt weakened. After that unscrew bolts 2 and 3 and remove the compressor so that not to damage thus any pipelines.
Substitute a jack under the power unit.
Unscrew four bolts of a back engine mount.
Unscrew fastenings of a forward support of the engine (fig. 373) .
Slowly lower the engine down. For this purpose you will need the assistant who will lower an automobile jack or the crane while you will continuously watch process of lowering of the engine through a motor compartment. If the engine for something is hooked, it should be liberated at once to avoid damage of details of a body or other knots and units. It concerns first of all the removed and tied-up details. Besides, if there is such possibility, it is possible to raise a forward part of the car to have more space for engine removal.
Installation of the engine is carried out in sequence, to removal process, however it is necessary to pay attention of return to the next moments:
- check on wear vyzhimny the coupling bearing in the working cylinder of coupling. In case of need replace the working cylinder together with the vyzhimny bearing of coupling. On cars considered in the book they always should be changed together;
- put on shlitsevy connection of a shaft of coupling a little lubricant. Volkswagen recommends to use in this place greasing with G 000 100 designation;
- establish the engine and a transmission in the correct situation in a motor compartment of the engine. When lifting the power unit pay attention, that it did not touch power shafts and be surely convinced that the engine together with a transmission is well fixed on a jack or the lift. As it was already told, it is thus most convenient to use the crane with a manual drive and an arrow;
- after the engine will be leveled concerning engine mount fastenings, tighten fastening bolts (approximately on 5–6 turns). Shake the engine here and there (it should not be finally drawn yet) a little and tighten bolts of forward and back fastenings of an engine mount. Tighten fastening of a forward beam of a suspension bracket, and also an arm of a back suspension bracket the moment of 55 N · m (in front in the hydraulic bearing).
Establish shaft of a drive of wheels and tighten bolts the corresponding moment.
Tighten bolts of fastening of the pump of the hydraulic booster of a steering the moment of 25 N · m. Do not forget about a bolt in the lower part of fastening of the pump. Establish a pump pulley, having fixed in motionless situation a shaft of the pump of the hydraulic booster of a steering by means of a six-sided key, and tighten three bolts the moment of 23 N · m. Tighten an arm fixing the pipeline of the pump of the hydraulic booster of a steering (20 N · м).
At installation of an exhaust pipe on a turbokompressor, and also in a junction of an exhaust pipe and the catalyst use new laying.
Insert a shaft of a drive of the right wheel into a transmission and tighten the persistent bearing (27 N · м).
Before installation of a shaft of a drive of the left wheel replace the persistent ring located on the end of a shaft.
Again establish a cross-section beam in the correct situation and tighten four bolts shown on fig. 367 the moment of 110 N · m.
Establish a balansirny suspension bracket on a transmission. Tighten a bolt on outer side the moment of 95 N · m.
Remove a steering from a wire and fasten from below to a cross-section beam. Bolts are tightened by the moment of 50 N · m.
Establish a wheel suspension bracket (see fig. 365 ). Tighten both bolts of the spherical hinge the moment of 55 N · m, a nut of the hinge of cross-section steering draft the moment of 30 N · m, a nut of fastening of connecting draft tighten the moment of 100 N · m. Perform the described operations from both parties of the car.
Lower the car on soil and tighten bolts of fastening of wheels (140 N · м).
Put on poliklinovy a belt, release a tension roller that he pulled a belt.
Connect the pipeline to the working cylinder of coupling and fix it a spring clip. Remove air from coupling system.
Establish details of the air filter in return sequence concerning removal process.
