11.6. Removal and installation of details of a hydraulic drive of a steering from the amplifier
Fig. 255. Details of fastening of elements of system of the amplifier of a steering: 1 — a collar of fastening of a highway; 2 — the prorate; 3, 4 — collars of fastening of a tube; 5 — a hydraulic booster tank; 6 — a spring collar of fastening of a tube; 7 — a tube of a returnable highway; 8 — a bringing tube; 9 — a bolt, 4 Н·м; 10 — a sealing ring; 11 — a pressure head tube; 12 — a hollow bolt-union, 30 Н·м; 13 — the prorate; 14 — the holder
Details of fastening of elements of a steering with the amplifier, a broad tank and connections of tubes and highways of hydraulic system are shown on fig. 255
. The pump is not subject to repair, therefore in case of failure it is necessary to replace it.
At installation it is necessary to observe the recommended moments of an inhaling, and also to consider the following:
- Collars 1 (fig. 255
) fastenings of highways fasten on a transmission;
- The stopper of a tank of the hydraulic booster has шлиц above and should open by means of horizontal the lever (for example, screw-drivers). Liquid level see подразд. 11.3;
- At removal of a tank 5 to cut collars and to replace them with collars of worm type;
The tube 7 returnable highways is marked by colour lines and an arrow on a broad tank;
- The entrance tube has colour marks which should coincide or with a case side, or with a mark in the pump console (depending on execution);
- Bolts 9 to tighten the moment no more than 5 Н·м;
- Always it is necessary to replace sealing rings of 10 highways of a high pressure. The hollow bolt-union should be tightened the moment 30 Н·м. As to establish a face head with динамометрическим a wrench happens difficultly to define the inhaling moment it is necessary approximately.
