SHOCK ABSORBER DISPOSAL 

Disposal Procedures 

1. Make an indentation 10 mm (0.4 in) from the bottom (4) of the tube (3) using a centerpunch. See Fig. 6 .  

2. Clamp the shock absorber in a vise horizontally with the shock absorber rod (1) completely extended. See 

Fig. 6 .  

3. 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.  

4. Make an indentation in the middle (2) of the tube (3) with a centerpunch. See Fig. 6 .  

CAUTION: Gas charged shock absorbers contain high pressure gas. Do not remove 

the snap ring from inside the top of the tube. If the snap ring is removed, 
the contents of the shock absorber will come out with extreme force which 
may result in personal injury. 

CAUTION: To prevent personal injury, wear safety glasses when center punching and 

drilling the shock absorber. Use care not to puncture the shock absorber 
tube with the centerpunch.

5. 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.  

6. 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.
