Removal and installation of a beam of a forward suspension bracket

After installation the beam of a forward suspension bracket should pass geometrical check.


 REMOVAL

1 Remove the bottom cover of an impellent compartment, address to the Section Removal and installation of the bottom cover of an impellent compartment.
2 Raise the engine and unscrew fastenings of support of the engine from a beam at the left and on the right, address to the Section Removal and installation of the pallet of a case.
3 Mark paint the provision of the corresponding forward wheel concerning a nave. It will allow to establish at assembly an otbalansirovanny wheel in its former situation. Weaken bolts of fastening of a wheel at the car standing on the earth. Lift a forward part of the car, put it on supports and remove a forward wheel.

4 Unscrew bolts of fastening of the bottom amplifier-1-(an arrow on an illustration).

5 If there is a road clearance sensor, disconnect it from a beam (the shooter on an illustration).

6 Disconnect the cross-section lever-1-from an engine beam at the left and on the right (shooters on an illustration).

7 Unscrew nuts (the shooter on an illustration) at the left and on the right. Disconnect the sharovy hinge of the cross-section lever-1-by means of a plastic fist.

8 Unscrew bolts of fastening and remove the steering mechanism - 1-from a beam of a suspension bracket-2-(shooters on an illustration).

9 Establish in the center under a beam the garage lift with wooden laying. Prop up a beam.

On an illustration the engine lift with BMW-312220 pro-rate is shown.

10 Unscrew bolts of fastening of a beam of a suspension bracket to an engine beam.
11 Carefully lower a beam by means of the garage lift.


 INSTALLATION

12 Establish a beam of a suspension bracket and fix an engine beam new bolts with the efforts specified in Specifications.

At first fix both back bolts, in relation to the direction "forward".

13 Fix the steering mechanism on a suspension bracket beam new being self-stopped nuts the moment of 42 N • m.
14 Clear of greasing a pin on the spherical hinge of the cross-section lever, and also an opening in a suspension bracket beam. Insert the hinge into an opening of a beam and press the lift up. Thus, the nut is easier for tightening. The moment of an inhaling makes 80 N • m.
15 Fix the holder of the cross-section lever on an engine beam at the left and on the right the moment of 60 N • m.
16 If the road clearance sensor acted in film, fix it on a suspension bracket beam.
17 Fix bolts the bottom amplifier the moment of 60 N • m.
18 Fix bolts of a support of the engine to an engine beam the moment of 47 N • m.
19 Establish the bottom cover of an impellent compartment, address to the Section Removal and installation of the bottom cover of an impellent compartment.
20 Remove the elevating device of the engine.
21 Establish into place a forward wheel so that the markings put at removal coincided. Previously grease with a thin layer of bearing greasing aligning belt of a disk of a wheel on a nave. Bolts of fastening of a wheel do not grease. Rusty bolts replace. Wrap bolts. Lower the car on wheels and tighten bolts cross-wise the moment of 100 N • m.
22 Measure geometrical parameters of a running gear on HUNDRED.
