1. Fix a rack, having clamped it in a vice; in order to avoid damage of a surface of a rack put on aluminum laying or wooden whetstones sponges of a vice. Avoid twisting of an adjusting bracket.
|
2. By means of the tool for compression of springs squeeze spring rounds so that pressure was taken off of the top cup. |
|
3. For ensuring access to a fixing nut remove a dustproof cap from the top part of a rack. Holding a shock-absorber rod from rotation by means of the method described in the subsection "Removal"
weaken a nut to such an extent that it could be removed by a hand. 4. Take the top basic knot, the top saddle of a spring, the twisted spring which is (still compressed) the lower saddle of a spring, the restrictive buffer of compression and a rubber casing. Carefully weaken and remove the tool for compression of springs. 5. Examine a twisted spring regarding detection of signs of the general wear, destruction or damages. Pay special attention to search of cracks and serious corrosion; at detection of the above-stated signs replace a spring. Check a spring tortsovka, having established it vertically on a flat surface and having put to its rounds parallel to a spring axis a template of a right angle. Admissions Specifications
do not make a reservation, however in case of detection of obvious deformation, replace a spring. 6. Remove a dustproof cap and examine shock-absorber section regarding detection of signs of leak of liquid, paying special attention to a piston rod epiploon. Check correctness of functioning of the shock-absorber, two or three times firm pressing having pressed a piston rod until the end of its course, then quickly make several short compression. Smooth resistant resistance has to be felt; if resistance unevenly, is too weak or at the movement of the piston unusual noise is heard, the shock-absorber has to be replaced. Examine a piston rod regarding detection of signs of corrosion or deformation, in case of an unsatisfactory state replace the shock-absorber. 7. Examine the compression course buffer, a rubber casing and saddles of a spring; in case of detection of signs of damage, wear or corrosion replace them. Remember that violation of integrity of the protection cover can lead to hit in the shock-absorber of dirt and, as a result, to its failure. |
8. Establish the lower saddle of a spring through a shock-absorber rod on a cup on the rack case.
|
|
9. Put on the rubber protection cover through a rod of the piston and establish it into place; the bottom edge of a casing has to be in 12 mm over a surface of the lower cup of a spring. Rotate a casing for combination of the tag made at its bottom edge with the lower adjusting bracket of a rack. |
|
10. Put on a dustproof cap the top part of the shock-absorber. |
|
11. Squeeze spring rounds by means of the tool for compression of springs. Establish a spring on the lower plate, having rotated it for combination of the end of a round with a ledge in the lower saddle. Make sure that compression of a spring is enough to establish the top clamps. |
|
12. Bend the top sponges of the protection cover at the top of a spring. |
|
13. Install the compression course buffer on a shock-absorber rod. |
|
14. Establish into place the top saddle of a spring, having combined a notch at its edge with a tag at bottom edge of the protection cover and the lower adjusting bracket of a rack. |
|
15. Establish the top basic knot and a new nut of a rod of the shock-absorber. Having used the method described in the subsection "Removal"
partially tighten a fixing nut. |
