Disposing of the shock absorber
Special tools and workshop equipment required
t  Drill Ø 3 mm (commercially available)
t  Drill Ø 6 mm (commercially available)
t  Safety goggles (commercially available)
t  Oil catch container (commercially available)
t  Pipe cutter, e. g. Stahlwille Express -150/3- (commercially available)
  Note
There are two ways of disposing of shock absorbers.
Degassing the front and rear pressurized shock absorbers
Version A: Degassing by drilling open
I - Front pressurized shock absorber
II - Rear pressurized shock absorber
–  Firmly clamp the gas pressure shock absorber vertically in the vice so that the piston points downwards.
  Caution
Use safety goggles when drilling.
   
–  Drill a hole Ø 3 mm -arrow A- through the outer pipe of the shock absorber.
  Note
Gas will escape during drilling.
–  Drill further until the inner pipe has also been drilled through (approx. 25 mm deep).
–  Drill a second hole Ø 6 mm -arrow B- through the outer and inner shock absorber pipe.
–  Hold the shock absorber over an oil catching pan, move the piston rod several times up and down over its entire stroke until no more oil escapes.
Degassing the front and rear pressurized shock absorbers
Variant B: Open with pipe cutter
I - Front pressurized shock absorber
II - Rear pressurized shock absorber
–  Firmly clamp the gas pressure shock absorber vertically in the vice so that the piston points upwards.
  Caution
Use safety goggles when drilling.

–  Drill a hole Ø 3 mm -arrow- through the outer pipe of the shock absorber.
  Note
Gas will escape during drilling.
–  Position a pipe cutter, e.g. Stahlwille Express -150/3-, as shown in the figure, and cut through the outer pipe of the shock absorber.
–  Pull the piston rod upwards and while doing so grip the inner pipe with pipe pliers and press it down in such a way that it remains in the outer pipe when the piston rod is slowly pulled out.
–  Pull the piston rod out of the piston pipe.
–  Empty the shock absorber pipe.
