• 0—1.0 mm {0—0.039 in}

Crankshaft Pulley Lock Bolt Installation Note

1. Install the SST on the camshaft as shown.

2. Verify that cylinder No.1 is at TDC of the compression stroke. (Crankshaft balance weight contacts SST.)

3. To position the crankshaft pulley, temporarily tighten it and, using a suitable bolt (M6 X 1.0 length 25 mm—35 mm {0.99 in—1.37 in}), fix the crankshaft pulley to the engine front cover.

4. Install the SSTs to the crankshaft pulley, lock the crankshaft against rotation.

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

a. Tighten to 96—104 N·m {9.8—10.6 kgf·m, 70.9—76.7 ft·lbf}

b. Tighten 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.

9. Remove the SST from the crankshaft pulley.

10. Rotate the crankshaft clockwise two 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.

Tightening torque:

• 18—22 N·m {1.9—2.2 kgf·m, 13.3—16.2 ft·lbf}
