2.  Tighten the crankshaft sprocket installation bolt.

Tightening torque
167—176 N·m {17.1—17.9 kgf·m, 124—129 ft·lbf}


Timing Chain Installation Note

Caution
•  If the engagement of the internal and external links for the timing chain is reversed, new contact marks will be produced on the vacuum pump sprocket, damaging the sprocket and decreasing the NVH performance. Therefore, when installing the timing chain to the vacuum pump sprocket, position it to the original contact marks on the timing chain.

Note
•  The reference and the 25th external link are the timing chain alignment marks.

Timing Chain Tensioner Installation Note

1.  Install the timing chain tensioner.

2.  Remove the wire or paper clip which has been installed to secure the plunger.


Front Oil Seal Installation Note

1.  Apply clean engine oil to the oil seal lip.

2.  Push the oil seal slightly in by hand.

3.  Tap the oil seal in evenly using the SST and a hammer. The oil seal must be tapped in until it is flush with the edge of the engine front cover.

Tightening torque
1: 38—52 N·m {3.9—5.3 kgf·m, 29—38 ft·lbf}
2: 19—25 N·m {2.0—2.5 kgf·m, 15—18 ft·lbf}
3: 19—25 N·m {2.0—2.5 kgf·m, 15—18 ft·lbf}


Crankshaft Position (CKP) Sensor Installation Note

Caution
•  When foreign material, such as iron chips, gets on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect engine control. Be sure there is no foreign material on the CKP sensor when replacing.

1.  Verify that the O-ring is not damaged.

•  If there is a damage, replace the CKP sensor.

2.  Verify that there is no foreign material on the CKP sensor flange surface and the installation surface.

3.  Apply a small amount of clean oil to the O-ring and the CKP sensor installation hole.

4.  Press in the CKP sensor until the CKP sensor flange surface firmly adheres to the installation surface.

5.  Verify that the O-ring is installed correctly to the sensor installation hole.

6.  Tighten the bolt.

Tightening torque
8—10 N·m {82—101 kgf·cm, 71—88 in·lbf}


Camshaft Position (CMP) Sensor Installation Note

Caution
•  When foreign material, such as iron chips, gets on the CMP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect engine control. Be sure there is no foreign material on the CMP sensor when replacing.

1.  Verify that the O-ring is not damaged.

•  If there is a damage, replace the CMP sensor.

2.  Verify that there is no foreign material on the CMP sensor flange surface and the installation surface.

3.  Apply a small amount of clean oil to the O-ring and the CMP sensor installation hole.

4.  Press in the CMP sensor until the CMP sensor flange surface firmly adheres to the installation surface.

5.  Verify that the O-ring is installed correctly to the sensor installation hole.

6.  Tighten the bolt.

Tightening torque
8—10 N·m {82—101 kgf·cm, 71—88 in·lbf}


Cylinder Head Cover Installation Note

1.  Apply sealant as shown in the figure.

Caution
•  Install the cylinder head cover before the applied sealant starts to harden.
