Shock-absorber recycling

Places of drilling of apertures in the shock-absorber case

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


Shock-absorber fastening in a vice at cutting of 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 25 bar. Therefore at shock-absorber opening fence off a workplace and necessarily put on goggles.


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

Shock-absorber drilling

1 Clamp the shock-absorber removed from the car vertically in a vice a rod downwards.
2 Drill aperture 3 mm in a point And an external cover of the shock-absorber.

At газонаполненных 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 aperture 6 mm in a point In so that to receive an aperture in an internal pipe.
4 Hold the shock-absorber over capacity and squeeze out oil rod moving every which way on full size of a course.
5 Allow to oil to flow out completely.
6 Utilize the shock-absorber as usual metal.

Shock-absorber cutting

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

At газонаполненном the shock-absorber there is a gas.


3 Lift a rod. Thus hold an internal pipe an alligator wrench and press downwards 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.
