Folksvagen Sharan/Sharan repair>> The steering hydraulic booster>> Hydraulic system>> Removal and installation of the pump of the hydraulic booster of a steering
The pump of the hydraulic booster of a steering should be removed during carrying out of various works to get access to other details in the engine. The arrangement of the pump of the hydraulic booster of a steering differs on the four-cylinder engine and on engine VR6, therefore works are described separately. The car should be raised and established on support that it was easier to reach separate details. At removal of the pump of the hydraulic booster of a steering the small amount of a hydraulic liquid will flow out.
Removal and installation of the pump of the hydraulic booster of a steering on the car with the four-cylinder engine
In drawing 272 the arrangement of the pump of the hydraulic booster of a steering is shown. At its dismantle remember, where bolts of various length have been established.
At installation of the pump follow the instructions resulted further:
- Regularly replace sealing rings;
- Never again fill in in hydraulic system the hydraulic liquid which has flowed out at removal of the pump of the hydraulic booster of a steering;
- The basic surface of the pump of the hydraulic booster of a steering and carving should be pure;
- Fill the pump of the hydraulic booster of a steering with the recommended liquid. Turn the pump some times that oil was in regular intervals distributed in it;

Fig. 273. Installation of the pump of the hydraulic booster of a steering (the four-cylinder engine): 1 — the pump; 2 — rotary скоба; 3 — a bolt, 25 Нм; 4 — a bolt, 25 Нм; 5 — a bolt with internal шестигранником, 25 Нм; 6 — a pulley





- Put on the pump of the hydraulic booster of a steering 1 (fig. 273), with the established bolts 3 on rotary скобу 2 fastenings. Tighten bolts 4. Establish on the pump of the hydraulic booster a pulley and tighten its bolts the specified moments of an inhaling;

Fig. 274. Installation rotary скобы with the pump of the hydraulic booster of a steering: 1 — rotary скоба; 2 — the pump; 3 — эксцентриковый a bolt; 4 — the holder; 5 — a bolt





- Establish скобу 1 (fig. 274) and the pump 2 with the help эксцентриковых bolts 3 on the holder 4. Twist эксцентриковый a bolt 3 in rotary скобу 1 so that the carving plug concerned the holder 4. A bolt do not tighten. Turn, but do not tighten a bolt 5;

Fig. 271. An arm of the pump of the hydraulic booster of a steering: 1 — a bolt, 25 Нм; 2 — a bolt, 25 Нм; 3 — a bolt, 25 Нм; 4 — скоба pump suspension brackets; 5 — a suspension bracket arm; 6 — a bolt, 25 Нм; 7 — adjusting скоба; 8 — an adjusting bolt; 9 — a pin (only on the petrol engine)





- Attach the holder with the pump and rotary скобой to an arm 5 (fig. 271 see) and to the block of cylinders. Wrap on some turns bolts 1, 2 and 3, and then tighten the moment 25 Нм;
- Attach adjusting скобу 7 bolts 6 to the block of cylinders. Establish an adjusting bolt 8 in rotary скобу. Tighten bolts 6 moment 25 Нм;
- Establish клиновой a belt and pull it;
- After installation of the pump of the hydraulic booster of a steering check up level of a hydraulic liquid in a receiver (item 12.3.1 see). After start of the engine liquid level should not go down.
Removal and installation of the pump of the hydraulic booster of a steering on engine VR6
The pump of the hydraulic booster of a steering established on engine VR6 and way of its fastening are shown in drawing 275. For its dismantle remove поликлиновой a belt (see подразд. 5.7). An order of performance of operations:
- Disconnect АБ;
- Establish a forward part of the car on support;
- Remove поликлиновой a belt;
- Turn away a hollow bolt 12 delivery pipelines and remove both sealing rings 11;
- ослабьте a collar of a hose of the vacuum pipeline also disconnect a hose from the pump of the hydraulic booster of a steering;
- Fix a pulley of the pump of the hydraulic booster of a steering in motionless position and remove a pulley;

Fig. 276. The pump is fixed by a bolt on the right (1) and at the left (2)





- Turn away bolts of fastening of the pump (fig. 276) and remove the pump;
- Fill the pump of the hydraulic booster of a steering with the recommended liquid. Turn the pump some times that oil was in regular intervals distributed in it;
- Wrap three bolts on the right side and two on the left side (fig. 276 see). The moment of an inhaling of bolts 25 Нм;
- Put on a pulley, fix it in motionless position and wrap 3 bolts with internal шестигранной a head the moment 25 Нм;

Fig. 277. Wrap bolt М8 in aperture A to weaken a tension приводного a belt





- ослабьте pressure of the device of a tension of a belt (fig. 277), lay a belt on pulleys and remove a bolt;

Fig. 275. Fastening of the pump of the hydraulic booster of a steering on engine VR6: 1 — bolts with internal шестигранником, 25 Нм; 2 — a bolt with internal шестигранником, length 30 mm, 25 Нм; 3 — a bolt with internal шестигранником, length 20 mm, 25 Нм; 4 — a washer; 5 — a bolt with internal шестигранником, length 38 mm, 25 Нм; 6 — bolts with internal шестигранником, length 30 mm, 25 Нм; 7 — an arm; 8 — a pulley; 9 — a hose collar; 10 — the pump of the hydraulic booster of a steering; 11 — a sealing ring; 12 — a hollow bolt; 13 — a hose





- Attach hoses to the pump (fig. 275 see). Wrap a hollow bolt 12 with new sealing rings (the moment of an inhaling 30 Нм). Put on a hose 13 the union and put on it a collar 9;
- Other works are spent to sequences, return to removal process. Fill in in the steering hydraulic booster a hydraulic liquid and remove from system air (item 12.3.1). Make a trial trip on small speed and check up hydraulic booster work.
