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 spring. The spring compressors must

be tightened alternately and evenly so as not to tilt the

spring.

3. Remove the piston rod lock nut.

CAUTION:

Do not reuse piston rod lock nut.

• Keep the 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
