      • SST: 09612-24014 
        • 09617-24011

      without SST 

      Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf) 

      with SST 

      Torque: 34 N*m (347 kgf*cm, 25 ft.*lbf) 

      HINT: 

      • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 300 mm (11.81 in.).
      • The torque shown above should be used for tightening without using SST. When the SST is used for tightening, the torque should be calculated based on the length of the SST. Refer to PRECAUTION .
  2. INSTALL V-BANK COVER SUB-ASSEMBLY  . Refer to INSTALLATION - Step 115
  3. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL  . Refer to INSTALLATION - Step 93
