FRONT SUSPENSION - FRONT SHOCK ABSORBER 31-13

(c). Tighten the lower mounting bolts of the
front shock absorber.
Torque: 110~130 N•m

(d). Tighten the retaining bolts of thelower
swing arm ball joint bracket.
Torque: 120~150 N•m

5. Install the front wheel (Refer to "Chapter 33 Tire & Wheel - Front Tire & Wheel,
Replacement")
6. Check after the installation
(a). After the shock absorber is installed, drive 10KM on a rugged road and touch the
surface of the shock absorber by hand. If there is significant difference between 31
two shock absorbers, it means that the resistance gap is large. The cooler shock
absorber met lower resistance. If the surface temperature is no higher than the
ambient temperature, it means the shock absorber met no resistance and didn't
work at all, which requires replacement.
(b). When the vehicle engages in an emergency brake in slow motion, if it shakes
vibrantly, it means the shock absorber is defective. Remove the shock absorber and
hold it upright on the jawed vice, with the lower end fixed. Press the shock absorbing
rod by force for several times, and you should feel stable resistance, which is
greater when pulling up (restoring) than when pressing down. If the resistance is
unable or there is no resistance at all, it means the oil is insufficient inside the shock
absorber or the valve parts are defective. Replace it accordingly.
(c). In case of noise in the shock absorber in use, it is because the shock absorber
knocks the spring or frame, the rubber pad is damaged or lost, the dust cylinder is
distorted or the oil/liquid is sufficient. Troubleshoot the situation and fix it accordingly.
