11.1.5. Removal and installation of the steering mechanism

Removal

If you found out that the steering mechanism is faulty, it is not recommended to make its repair independently. As for repair special tools are required, it is better to provide it to dealer office of service (or completely to replace knot). The order of removal and installation of the steering mechanism is given below.


 PERFORMANCE ORDER

  1. On the E28 models ("retro") discharge hydraulic system, having squeezed out a pedal of a brake about 20 times.
  2. By means of a big syringe or the manual pump drain the tank of hydraulic system of hydrostrengthening of a wheel (see. Head Routine maintenance of the car).
  3. To Poddomkratta a front of the car and reliably establish it on axial support.
  4. Prop up a forward part of the engine a jack on wheels. Place wooden whetstone between a head of a jack and the case pallet not to damage the pallet.
  5. Give sharnirny bolts on the internal ends of levers of a suspension bracket (see. Head Forward suspension bracket).
  6. Give nuts on the left and right support of the engine (see. Head Engine).
  1. Give fixing bolts (on early models on two from each party, on later - on three from each party) on a cross-section beam of a stretcher and remove a stretcher.
  1. Give nuts and bolts of fastening of a steering shaft to a worm shaft of the steering mechanism. Raise a steering shaft up and remove it from a worm shaft. Examine a steering shaft on existence of signs of wear. If it is worn-out or jam kardanny hinges, replace it.
  1. Give hollow bolts and disconnect inlet (the right arrow) and returnable lines (the left arrow) hydraulic system from the steering mechanism. Pay attention that a hollow bolt of the union of the returnable line more than a bolt of the union of the inlet line (it is shown for models with left foreign management). Stop up the ends of lines not to allow pollution and liquid loss. Will throw out sealing washers - at assembly it is necessary to establish the new.
  1. Give bolts of fastening of the steering mechanism and remove the steering mechanism. The bolt specified by an arrow, holds the steering mechanism on a cross-section beam of a stretcher. Access to a nut which is not visible on a photo above, is provided through an opening in a cross-section beam (on a photo the engine is removed that it was visible better; the model with left foreign management) is shown:
  1. This bolt (it is specified by an arrow) holds the steering mechanism on a body (the nut which is not visible on a photo, is on the forward party of the mechanism):
  1. If it is necessary to disconnect a steering soshka from a sector shaft of the mechanism (for repair of the mechanism or soshka replacement), put labels on both details that then it is correct to bring together them. Give a fixing nut and a washer of a steering soshka. If necessary for removal of a soshka use a stripper.

Installation

 PERFORMANCE ORDER

  1. Establish a steering soshka, having combined put before a label. Then tighten a nut with demanded effort.
  2. After installation the steering soshka should not have any appreciable axial люфта within 100 about from neutral situation. If люфт after all is, check the following details:
    • Sector shaft and bearings (on wear)
    • Persistent washer and head of an adjusting bolt (on wear)
    • Ball nut and worm shaft (on wear)
  3. Establish the steering mechanism. Combine labels on a shaft of the steering mechanism and on a steering shaft and tighten bolts of fastening of the steering mechanism with demanded effort.
  4. Other part of procedure of installation repeats removal upside-down. Do not forget to establish new lock-nuts on a steering shaft, average steering draft, the steering mechanism and a cross-section beam. Use new sealing washers on shtutserny connections of hydraulic lines.
  5. Address to Head Routine maintenance of the car and fill the tank of hydraulic system of strengthening of a wheel with the recommended liquid, then pump over system as it is described in the Section Pumping of hydraulic system of the mechanism of hydrostrengthening of a wheel. Check, whether there are no leakages of liquid in lines and connections.
