2UR-GSE ENGINE MECHANICAL: CAMSHAFT: INSTALLATION

1. INSTALL NO. 3 CAMSHAFT

(a) Apply a light coat of engine oil to the camshaft journals.

(b) Install the No. 3 camshaft to the cylinder head sub-assembly.

2. INSTALL NO. 4 CAMSHAFT

(a) Apply a light coat of engine oil to the camshaft journals.

(b) Install the No. 4 camshaft to the cylinder head sub-assembly.

3. INSTALL CAMSHAFT BEARING CAP (for Bank 1)

NOTICE:
When rotating the camshafts without the timing chains installed, be careful to ensure that the valves do not contact the pistons. If contact occurs between the valves and pistons, damage may result.

(a) Make sure that each knock pin of the camshafts is positioned as shown in the illustration.





(b) Apply a light coat of engine oil to the camshaft housing and bearing caps.

(c) Confirm the marks and numbers on the camshaft bearing caps and place them in their proper positions and directions.





(d) Temporarily install the 20 bolts in the sequence shown in the illustration.

Bank 1:

Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)

(e) Tighten the 20 bolts in the sequence shown in the illustration.

Torque : 19 Nm (190 kgf-cm, 14 ft-lbf)

4. INSTALL CAMSHAFT

(a) Apply a light coat of engine oil to the camshaft journals.

(b) Install the camshaft to the cylinder head sub-assembly.

5. INSTALL NO. 2 CAMSHAFT

(a) Apply a light coat of engine oil to the camshaft journals.

(b) Install the No. 2 camshaft to the cylinder head sub-assembly.

6. INSTALL CAMSHAFT BEARING CAP (for Bank 2)

NOTICE:
When rotating the camshafts without the timing chains installed, be careful to ensure that the valves do not contact the pistons. If contact occurs between the valves and pistons, damage may result.

(a) Make sure that each knock pin of the camshafts is positioned as shown in the illustration.





(b) Apply a light coat of engine oil to the camshaft housing and bearing caps.

(c) Confirm the marks and numbers on the camshaft bearing caps and place them in their proper positions and directions.





(d) Temporarily install the 20 bolts in the sequence shown in the illustration.

Bank 2:

Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)

(e) Tighten the 20 bolts in the sequence shown in the illustration.

Torque : 19 Nm (190 kgf-cm, 14 ft-lbf)
