4.3.2. Loading of a support of a wheel in own weight of the car
All bolts of details with sajlent-blocks should be definitively tightened at suspension bracket installation in the position corresponding to the equipped weight of the car (the car незагружен).
Rezinometallichesky hinges (sajlent-blocks) have the limited working range of twisting.
Therefore the suspension bracket should occupy the position corresponding to the equipped weight of the car (the car незагружен).
Otherwise in the sajlent-block there will be internal pressure which will lead to reduction of service life of this detail.
At the expense of lifting of a suspension bracket of a corresponding wheel by means of a rack for the engine and a transmission and the pallet it is possible to simulate the given position on the lift.
|Fig. 4.46. Measurement of loading in weight of the car
Before the beginning of works measure, for example, by means of a roulette, the size a from the middle of a nave of a wheel to a wing bottom edge (fig. 4.46
Measurement should is spent on the car having the equipped weight (the car незагружен).
Write down the received value. It will be necessary for a definitive inhaling of bolts and nuts.
Before to raise a suspension bracket of a corresponding wheel, the car is necessary for attaching to arms of the lift by means of tension belts.
Otherwise, it can slide off the lift.
Turn a nave so that one of apertures under a wheel bolt was above.
Attach a support by means of a wheel bolt to a wheel nave.
|Fig. 4.47. A raising of the case of the bearing of a wheel
Lift the case of the bearing of a wheel by means of a rack for the engine and a transmission until the size Ťať (fig. 4.47
) will be reached
Definitive inhaling of corresponding bolts / of nuts make only on reaching measured before the beginning of works of the size a between the middle of a nave of a wheel and a wing bottom edge
It is forbidden to lift or lower the car when the jack for engines and transmission units is under the car.
The rack for the engine and a transmission should remain under the car not longer, than it is required for performance of works.
Definitively tighten corresponding bolts / of a nut.
Lower the case Hubs the bearing.
Clean a jack for engines and units of transmission from under the car.
Remove basic fastening.
