Control functions 1. 2. Loosen the locknut. To increase the spring preload and thereby harden the suspension, turn the adjusting nut in direction (a). To decrease the spring preload and thereby soften the suspension, turn the adjusting nut in direction (b). Center shock absorber 1 2 (a) (b) 1. Spring preload adjusting nut 2. Distance A 3. Locknut 3 TIP The spring preload setting is determined by measuring distance A, shown in the illustration. The longer distance A is, the higher the spring preload; the shorter distance A is, the lower the spring preload. Spring preload setting*: Minimum (soft): 161 mm (6.34 in) Standard: 162 mm (6.38 in) Maximum (hard): 172 mm (6.77 in) * Distance A changes 1.5 mm (0.06 in) with each full turn of the adjusting nut. 3. Tighten the locknut to the specified torque. NOTICE: Always tighten the locknut against the adjusting nut, and then tighten the locknut to the specified torque. [ECS00860] Tightening torque: Locknut: 42 Nm (4.2 m·kgf, 30 ft·lbf) ESU13132 1. 2. Loosen the locknut.

[ECS00860] Adjusting the spring preload of the center shock absorber and the rear torsion springs The spring preload can be adjusted by turning the adjusting nut on the center shock absorber and the adjusters on the rear torsion springs. Adjust the spring preload as follows. 22
