    CAUTION:
    • Install coil spring as shown in the figure with large diameter side [100 mm (3.94 in)] up and small diameter side [90 mm (3.54 in)] down. (Distinction marks are 4.75 and 5.75 turn from the lower side end).
    • Be sure a spring compressor is securely attached to coil spring. Compress coil spring.
  3. Apply soapy water to bound bumper. Insert bound bumper into shock absorber mounting bracket, and then install it to shock absorber together with rubber seat.
    CAUTION: Do not use machine oil.

    • Install shock absorber mounting bracket as shown in the figure.
      CAUTION:
      • Coil spring is securely seated in spring mounting groove of rubber seat.
      • The bottom part of spring should be at the position of A point of spring seat.
  4. Secure piston rod tip so that piston rod does not turn, then tighten piston rod lock nut with specified torque.
  5. Gradually release a spring compressor, and remove coil spring.
    CAUTION: Loosen while making sure coil spring attachment position does not move.
  6. Remove the shock absorber attachment from shock absorber.
