7.2.4. Replacement of a spring of a back suspension bracket
Replace a spring at mechanical damage or considerable draft. Draft signs:
– deterioration in smoothness of the course, frequent "breakdowns" of a suspension bracket;
– the visible distortion of a back part of the car or a considerable difference on height of forward and back parts which arose in use;
– strongly expressed traces of impact of rounds of a spring.
Note
Replace springs in a set (left and right at the same time).
|
You will need the device for compression of springs.
Good advice
It is more convenient to perform work on the elevator.
|
1. Establish an antiretractable emphasis ("boots") under forward wheels and you will hang out a beam of a back suspension bracket.
2. Establish a jack and slightly to a poddomkratta a back beam to unload a bolt of the lower fastening of the shock-absorber.
|
3. Holding a bolt from a provorachivaniye, the second key turn off a nut …
|
4. … take out a bolt and take a shock-absorber eye from an arm of the lower fastening.
Preventions
You do not take the shock-absorber aside on distance bigger, than it is necessary for work, in order to avoid a rod bend.
Do not disconnect at the same time both lower fastenings of shock-absorbers from a beam of a back suspension bracket.
|
5. Accurately lower a jack to unload a spring …
6. … also take out a spring.
Note
As a rule, there is enough length of a brake hose that it did not stretch at removal of a spring, but if you see that the hose stretches, disconnect it for the period of replacement of a spring not to damage (see. "Replacement of brake hoses"), or use the special device for a coupler of springs.
|
7. Take the top laying of a spring …
|
8. … also remove the lower laying from the platform on a beam of a back suspension bracket.
|
Prevention
Replace the damaged laying of a spring new.
|
9. Install a spring with laying on the car as it should be, the return to removal. Similarly replace the second spring.
