NOTE:
- Do not tighten the crankshaft pulley lock bolt during this step.

4. Hold the crankshaft pulley using the SSTs.






5. Tighten the crankshaft pulley lock bolt in the following two steps using the SST (49 D032 316).

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

6. Remove the bolt (M6 X 1.0) installed to the crankshaft pulley.

7. Remove the SST from the camshaft.

8. Remove the SST installed to 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. Testing and Inspection

10. Rotate the crankshaft clockwise two turns and inspect the valve timing.

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

11. Install the cylinder block lower blind plug.






Tightening torque
- 18-22 Nm {1.9-2.2 kgf-m, 14-16 ft-lbf}
