Caution: Gas charged shock absorbers contain high pressure gas. Do not attempt
to cut the shock open before all gas pressure is released. Failure to do so
may result in personal injury.
Caution: To prevent personal injury, wear safety glasses when centerpunching
and drilling the shock absorber. Use care not to puncture the shock absorber
tube with the centerpunch.
- Make an indentation (2) 50 mm (2 in) from the top (2) of the tube using a centerpunch.
- Make an indentation (4) 25 mm (1 in) from the bottom (A) of the tube using a centerpunch.
- Clamp the shock absorber in a vise horizontally with the shock absorber rod (1) completely extended.
- Drill a hole in the shock absorber at the centerpunch (4) using a 5 mm (3/16 in) drill bit. Gas or a gas/oil mixture will exhaust when the drill bit penetrates the shock absorber. Use shop towels in order to contain the escaping
oil.
- Drill a second hole in the shock absorber at the centerpunch (2) using a 5 mm (3/16 in) drill bit. Oil will exhaust when the drill bit penetrates the shock absorber. Use shop towels in order to contain the escaping oil.
- Remove the shock absorber from the vise. Hold the shock absorber over a drain pan horizontally with the holes down. Move the rod (1) in and out of the tube (3) to completely drain the oil from the shock absorber.
