10.3. Check of a state and replacement of spherical support of a forward suspension bracket
Check of a condition of a spherical support
|
|
- Release a spherical support from a rotary fist and by means of a dynamometer of bezmenny type measure the assembly resistance to a deviation in the plane of an axis of a spherical finger (see the illustration Check of a Condition of a Spherical Support). If the result of check exceeds the limit of the admissible range (0.8 — 7.8 kgfs), replace a support.
- With a nut, navernuty on the place, measure the size of torque of axial rotation of a shaft of a spherical finger (see
the illustration Check of a Condition of a Spherical Support) — the nominal rate makes 0.5 — 5.0 Nanometers. In case of need make assembly replacement.
- The car also establish to Poddomkratta it on props (see
the illustration Scheme of an Institution of Props for fixing of the car in the lifted situation).
|
- Attentively examine protective covers of spherical support on existence of signs of development of leak of lubricant. Check a condition of covers — existence of cracks and cuts is not admissible.
|
|
- Fix the dial measuring instrument on the cross lever of a suspension bracket, having rested its plunger in lower edges of a support of the brake mechanism, then, working with mount as the lever, wring out the lever from a rotary fist down and consider instrument reading. In the presence of a little noticeable axial side play (see the illustration Check of a Condition of a Spherical Support) the spherical support is subject to replacement.

|
- The faulty spherical support is subject to replacement.

Replacement
|
|
- Car front also establish to Poddomkratta it on props (see the illustration Scheme of an Institution of Props for fixing of the car in the lifted situation).
- Release a power shaft from stupichny assembly.
- Release a finger of a spherical support from a rotary fist.
- Remove a spherical support from the cross lever of a suspension bracket.
- Installation of components is made as it should be, the return to an order of their dismantle. Track that all fixture was tightened with the required effort.
