Rear Gas-Filled Shock Absorbers, Venting And Draining
The procedure is the same for standard shock absorber and controlled shock absorbers.
Special tools and workshop equipment required
- Hand drill
- 3 mm diameter drill bit.
- 6 mm diameter drill bit
- Oil collecting container
- Protective Eyewear
- Safety Gloves
Procedure
-- Secure the gas-filled shock absorber vertically in a vise with the piston rod facing down.
Risk of injury due to flying metal shavings.
Irritation and injury to skin and eyes possible.
- Wear protective eyewear.
- Wear safety gloves.
-- Drill a 3 mm hole -item A- through the shock absorber outer tube.
TIP:
- Gas escapes when drilling.
-- Continue drilling until the tube inside is drilled through (approximately 25 mm deep).
-- Drill a second 6 mm hole -item B- through the outer and inner shock absorber tubes.
-- Hold the shock absorber over an appropriate container for catching oil and move the piston rod repeatedly through the entire stroke until no more oil flows out.
