10.2.2. Changes in hydraulic system

THE GENERAL DATA

Hydraulic system

1. The return pipeline Going from the steering valve The inhaling moment: 40 Н.м. 2. 20 Н.м. 3. A high pressure tube 4. 35 Н.м. Use only a bolt "банджо" without a filter 5. The hydraulic pump Is not subject to repair 6. A soaking up hose 7. 50 Н.м. 8. A hose of the return pipeline 9. The rubber plug 10. 10 Н.м. 11. An arm For fastening of the accumulator of pressure 12. The pressure accumulator Before removal reduce pressure, having pressed a pedal of a brake about 20 times at the switched off engine Before removal of the old accumulator drill an aperture in diameter about 3 mm on the party with air (the party on which there are no connections)

13. 35 Н.м. Use a bolt "банджо" with a filter 14. A steering drive Has a clip for fastening of a tube of a high pressure 15. A return hose 16. A tank With the alarm indicator of level of oil Fill with oil for greasing of hydraulic systems Check of level of oil: turn forward wheels directly, allow to the engine to work in a single mode about 2 minutes then muffle the engine and check up oil level 17. A high pressure tube Before removal reduce pressure, having pressed a pedal of a brake about 20 times at the switched off engine 18. Сервоцилиндр brake system Is not subject to repair 19. The panel of devices 20. The return pipeline 21. A tee

Always replace sealing rings in places of connections.

The prevention

Put on goggles at aperture drilling in the pressure accumulator.

Since 1990 following elements have been modified on cars with a hydraulic drive of brakes:

      – High pressure tubes;
      – Bolts "банджо" for connections of tubes of a high pressure in connection places to the hydraulic pump and the pressure accumulator;
      – Sealing rings for connections of tubes of a high pressure;
      – The hydraulic pump;
      – The pressure accumulator;
      – An arm of the accumulator of pressure;
      – The plug of fastening of the accumulator of pressure.

These changes were entered gradually since model: the Compartment 8B LA 006 861.

Changes in hydraulic system

1. A high pressure tube With flutes for installation of sealing rings 2. A bolt банджо With the filter M10x1 (Was M12x1.5), 30 Н.м. 3. Sealing rings Always replace Earlier were metal 4. The hydraulic pump Carving for connection of a tube of a high pressure = M10x1 (was M12x1.5) Use new metal epiploons at connection VW 1354 5. Plugs, grease with anticorrosive greasing at installation

6. Fastening Establish plugs and put on the accumulator 7. A bolt "банджо" With the filter M10x1 (Was M12x1.5) 8. The pressure accumulator Carving for connection of a tube of a high pressure = M10x1 (was M12x1.5) Pressure of the new accumulator = 78-82 Bar 9. An arm For fastening of the accumulator of pressure Establish on the car before installation of hydraulic tubes
