        Valve Clearance (cold)
        0.14 mm (0.00551 in.)
      2. Using SST and a screwdriver, tighten the valve adjusting nut while keeping the valve adjusting screw in position.

        *1 Valve Adjusting Screw
        *2 Valve Adjusting Nut
        *a Length of SST 150 mm (5.91 in.)

        SST
        09248-56010
        Момент затяжки
        without SST [Torque (N*m(kgf*cm, ft.*lbf))]
        20 N*m  { 204 kgf*cm, 15 ft.*lbf }
        with SST [Reading of Torque wrench (N*m(kgf*cm, ft.*lbf))]
        13 N*m  { 133 kgf*cm, 10 ft.*lbf }
        Tip:
        • This torque value is effective when SST is parallel to the torque wrench.

        • The "with SST" torque value is effective when using SST with a fulcrum length of 150 mm (5.91 in.).

        • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 300 mm (11.81 in.).

        • If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values.
