Forward spring and amortization rack

Removal

Type of a forward suspension bracket on the one hand.

Apparently from an illustration is higher, the new forward suspension bracket developed by Nissan firm has an unusual appearance. Though amortization racks with screw springs and hydraulic shock-absorbers are used, the bottom party of an amortization rack is equipped with fastening which is usually used on the shock-absorber of the back shock-absorber. Removal and installation thanks to this constructive decision are carried out very simply.

It is necessary to remember that the amortization rack is not subject to dismantling i.e. if the shock-absorber lost the amortiziruyushchy properties, it is necessary to replace all rack.

 PERFORMANCE ORDER

  1. Lift a forward part of the car and establish on support.
  2. Remove a wheel.
  3. Establish under the cross-section lever the lift and slightly raise it.
  4. From the interior of an impellent compartment weaken three nuts which hold an amortization rack on a support from above. Not to delete a nut in the middle as it holds an amortization rack in a collected condition. In case of replacement of details of an amortization rack it can be unscrewed.
  5. Weaken a bolt and a nut on the bottom party of an amortization rack, beat out a bolt and release an amortization rack.
  6. Slowly lower the lift, deducing at the same time rotary fist from gearing with an amortization rack.

Dismantling of an amortization rack

If necessary to disassemble an amortization rack before the beginning of work it is necessary to consider the next moments:

Screw springs of various models described in this Management differ from each other. Various springs depending on the established engine are besides established. At the order of new details it is necessary to remember it. Springs have color designations. Also springs cannot be confused in places if both springs are removed.

For shock-absorber replacement the rack does not understand. If amortization properties are lost or the piston rod is worn-out, it is necessary to replace all amortization rack.

At replacement of a screw spring watch, that dirt did not get to an amortization rack.

Never to clamp an amortization rack in a vice, and to make a plate on which it is possible to screw a rack. The plate can be clamped in a vice.

On an illustration lower replaced details of an amortization rack are represented.

Separate elements of an amortization rack

1 — the top rubber plug
2 — a nut, 45-55 N • m
3 — laying
4 — the top support of a spring
5 — the top rubber pillow
6 — the top rubber plug
7 — a cup
8 — a dustproof cuff
9 — the buffer of a course of compression
10 — a screw spring
11 — an amortization rack

The szhimatel of springs is necessary for dismantling.

 PERFORMANCE ORDER

  1. Being guided by an illustration below, compress a spring while the top support of a rack cannot be turned a hand. For this purpose two hooks of a szhimatel can be used.

Weakening of a nut of a rod of the piston. The spring is compressed by a szhimatel and for keeping of a rod the wrench is used.

  1. Weaken a nut of a rod of the piston on inside of the top support, holding a piston rod a wrench, apparently from an illustration.
  2. On the basis of an illustration remove all details of the top support and then a screw spring from an amortization rack. Watch not to scratch and to damage a piston rod.
  3. Carefully clear details in flushing gasoline and to dry up the compressed air. Watch, that all details were free from a dust and dirt. Well check details. The shown on assembly diagram worn-out or damaged details can be replaced with the new.

Assembly of an amortization rack

Being guided by an illustration, collect an amortization rack, considering the following instructions:

 PERFORMANCE ORDER

  1. To force out air from the shock-absorber, having shifted several times the piston up-down, thus the piston should pass each time all the course. To extend a piston rod if the party of a rotary fist is below. Move the piston if the party of a rotary fist is above.
  2. Compress a spring a szhimatel and put on an amortization rack. Watch, that it correctly sat down in a cup.
  3. Put on one after another all details shown on an illustration, an amortization rack. Put on a piston rod the buffer of a course of compression, a dustproof cuff and a cup in the correct direction. Before putting on the top support of an amortization rack, it is necessary to find dredging on an external circle. Put on a support so that dredging at the established amortization rack was turned to an internal part of the car. In this regard watch shock-absorber fastening. In it the arrow who on the left side should be turned back, and on the right side forward is beaten out. Dredging and an arrow follows сориентировать from each other.
  4. Screw a new nut of a rod of the piston, holding a rod, as is shown in an illustration and tighten a nut with effort of 18-24 N • m.
  5. Slowly release a szhimatel of a spring and check, that the spring entered into a cup on an amortization rack.

Installation of an amortization rack

Installation of an amortization rack is carried out in return to sequence removal. Watch, that the brake hose at connection was not overwound.

 PERFORMANCE ORDER

  1. After installation turn a steering wheel from an emphasis against the stop and check, that the hose did not come across any details of the car. Values of the moments of an inhaling are given specified in Specifications at the beginning of Head.
  2. Tighten three nuts of the top support of an amortization rack on body fastening with effort of 45-53 N • m. Hammer a shock-absorber bolt on the bottom party to the cross-section lever.
  3. In summary pump over brake system if the brake hose was disconnected.
