Shock-absorber utilization

Places of drilling of openings in the shock-absorber case

And — an opening in diameter of 3 mm
In — an opening in diameter of 6 mm


Shock-absorber fastening in a vice when cutting the case of the shock-absorber

 


That the shock-absorber could be used again, it is necessary to merge from it oil.

At all it is not necessary to pour out oil of the shock-absorber together with a household waste since it can harm to environment. Local authorities should inform on places of reception of the fulfilled oil.

Pressure of gas in the shock-absorber makes to the 25th bar. Therefore when opening the shock-absorber fence off a workplace and surely put on goggles.


Be opened the shock-absorber can in two ways: by its zasverlivaniye and a cutting.

Shock-absorber drilling

1 Clamp the shock-absorber removed from the car vertically in a vice a rod down.
2 Drill an opening of Ø3 of mm in a point And an external cover of the shock-absorber.

At gas-filled shock-absorbers gas leaves after the first wall of a pipe is drilled. Observe safety distance. Continue to drill further to an internal pipe (about 25 mm).


3 Drill other opening of Ø6 of mm in a point In so that to receive an opening in an internal pipe.
4 Hold the shock-absorber over capacity and squeeze out oil rod moving in different directions on full size of a course.
5 Let's to oil flow out completely.
6 Utilize the shock-absorber as usual metal.

Shock-absorber cutting

1 Clamp an amortization rack in a vice.
2 Establish труборез, for example Stahwille Express 150/3, and cut an external pipe.

At the gas-filled shock-absorber there is a gas.


3 Lift a rod. Thus hold an internal pipe an alligator wrench and press down so that it at slow promotion of a rod remained in an external pipe.
4 Remove a rod from an internal pipe.
5 Put the shock-absorber over capacity and merge completely oil.
6 Utilize the fulfilled oil according to the established rules.
