Front Gas-Filled Struts, Emptying
Front gas-filled struts, emptying
A - Emptying by drilling
- Clamp gas-filled shock absorber vertically in vise, with piston rod pointing downward.
CAUTION! Always wear eye protection when performing this procedure.
- Drill a 3 mm diameter hole - arrow A - through outer tube of strut.
Note: Gas will escape during drilling.
- Continue drilling until inner tube is penetrated (approx. 25 mm deep).
- Drill a second 6 mm diameter hole - arrow B - through outer and inner tubes of strut.
- Hold strut over an appropriate container for catching oil and move the piston rod up and down several times through the entire stroke until no more oil comes out.
B - Opening strut with a pipe cutter
CAUTION! Always wear eye protection when performing this procedure.
- Drill a 3 mm diameter hole - arrow - through outer tube of strut, or saw through side of tube.
Note: Gas will escape while drilling or sawing.
- Apply pipe cutter (e.g. 150/3 Stahlwille Express) as shown in illustration and cut through outer tube.
- Pull piston rod upward, at the same time holding the inner tube securely with pliers and pressing it downward, so that it remains in the outer tube when the piston rod is pulled up slowly.
- Remove piston rod from inner tube.
- Drain strut tube.
