DISASSEMBLY
1. Set the shock absorber in a vise, then loosen (without removing)
the piston rod lock nut as shown.
CAUTION:
Do not remove piston rod lock nut at this time.
2. Compress the coil spring using commercial service tool until the
shock absorber mounting insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two spring compressors are
firmly hooked on the coil spring. The spring compressors
must be tightened alternately and evenly so as not to tilt the
coil spring.
3. Remove the piston rod lock nut.
• Discard the piston rod lock nut, use a new nut for assembly.
4. Remove the components from the shock absorber.
• Keep the coil spring compressed in the commercial service
tool if reusing it for assembly.
INSPECTION AFTER DISASSEMBLY
Shock Absorber Assembly
• Check for smooth operation through a full stroke, both compression and extension.
• Check for oil leakage on welded or gland packing portions.
• Check piston rod for cracks, deformation or other damage and replace if necessary.
Mounting Insulator and Rubber Parts
Check cemented rubber-to-metal portion for separation or cracks. Check rubber parts for deterioration and
replace if necessary.
Coil Spring
• Check for cracks, deformation or other damage and replace if necessary.
• Check the coil spring free height.
