Crankshaft Pulley Lock Bolt Removal Note

1.  Rotate the crankshaft in the direction of the engine rotation and remove the cylinder block lower blind plug when the No. 1 cylinder is at the point prior to top dead center (TDC) of compression, then install the SST.

5.  Tighten the crankshaft pulley lock bolt in the order shown in the following two steps.

Tightening torque
Step 1: 96—104 N·m {9.8—10 kgf·m, 71—76 ft·lbf}
Step 2: 87—93°

6.  Remove the M6 x 1.0 bolt.

7.  Remove the SST from the camshaft.

8.  Remove the SST from the cylinder block lower blind plug hole.

9.  Verify that the teeth of the crankshaft pulley pulse wheel and the detection area of the crankshaft position sensor are installed to the correct positions. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

10.  Rotate the crankshaft clockwise 2 turns until the TDC position.

•  If not aligned, loosen the crankshaft pulley lock bolt and repeat from Step 1.

11.  Install the cylinder block lower blind plug.
