How to Disassemble Motorcycle Coilover Shocks
Some manufacturers insist that shock absorbers should not be disassembled but replaced as whole parts. Other vendors understand that the springs can be taken off. Disassembling shocks beyond that may void your warranty and cause you injury. The procedures and techniques are similar for all motorcycle shocks for all bikes including dirt bikes, sport bikes, touring models and cruisers. In a nutshell, you compress the shock absorber in a mechanical or hydraulic press and free the spring. In the United States, Progressive Suspension makes a mechanical press specifically to accomplish this job.
Instructions
- 1
Clean the shock absorber to be disassembled with solvent and rags.
2Place the bottom of the shock absorber on a wooden block in the hydraulic or mechanical press. Ensure the shock is vertical and immobilize the shock.
3Lower the ram of the mechanical or hydraulic press until it touches the top, or long eye, of the shock absorber. Slowly compress the top of the shock absorber and the shock spring until the shock absorber retainer ring and keeper plate separate.
4Remove the retaining ring with a mechanics awl. Remove the pressure on the top of the shock and remove the shock from the press.
5Separate the spring plate from the damper tube.
6Line the jaws of a bench vise with rags. Clamp the long eye in the vise so the shock is upside down.
7Loosen the long eye nut with an open-end wrench. Remove the long eye nut and the spring plate.
