Fulcrum Length

30 mm

Fulcrum Length

300 mm

SST: 09224-00011

Torque:

without SST :

44 N·m {449 kgf·cm, 32 ft·lbf}

with SST :

40 N·m {408 kgf·cm, 30 ft·lbf}

NOTICE:

The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.).
The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 300 mm (11.81 in.) (See page ).

This torque value is effective when SST is parallel to the torque wrench.

HINT:

Perform "Inspection After Repair" after replacing the air fuel ratio sensor (See page ).

(b) Connect the air fuel ratio sensor connector.

2. INSPECT FOR EXHAUST GAS LEAK

3. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR
