(a) Secure the hexagonal portion of the camshaft in a soft jaw vise.

(b) Align and fit the knock pin of the camshaft to the knock pin hole of the camshaft timing gear assembly.

*a	Knock Pin
*b	Knock Pin Hole

*1	Camshaft Timing Gear Assembly
*a	Camshaft Flange
*b	No Gap

(d) Tighten the bolt with the camshaft timing gear assembly secured in place.

Torque:

54 N·m {551 kgf·cm, 40 ft·lbf}

NOTICE:

When tightening the bolt, do not allow the camshaft timing gear assembly to rotate.

(e) Check that the camshaft timing gear assembly can move in the retard direction (clockwise) and locks in the most retarded position.

5. INSTALL CAMSHAFT

HINT:

Perform "Inspection After Repair" after replacing the camshaft.

Click here

(a) Clean the camshaft journals.

(b) Apply a light coat of engine oil to the camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.

*a	Paint Mark
*b	Timing Mark

6. INSTALL NO. 2 CAMSHAFT

HINT:

Perform "Inspection After Repair" after replacing the No. 2 camshaft.

Click here

(a) Clean the No. 2 camshaft journals.

(b) Apply a light coat of engine oil to the No. 2 camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.

7. INSTALL CAMSHAFT BEARING CAP

(a) Check the marks and numbers on the camshaft bearing caps, and then remove the service bolts and spacers in the order shown in the illustration. Immediately after removing the service bolts and spacers for 1 camshaft bearing cap, install the camshaft bearing cap with the bolts in the order shown in the illustration.

*a	Service bolt and spacer (Used to temporarily secure the camshaft housing sub-assembly)	*b	Knock Pin
*c	Paint Mark	*d	Timing Mark
*e	The removal order of the service bolts and spacers for temporarily tightening the camshaft housing sub-assembly	*f	The installation order of the parts

Torque:

27 N·m {275 kgf·cm, 20 ft·lbf}

NOTICE:

If the bolts are loosened all at once, seal packing on the camshaft housing sub-assembly and cylinder head sub-assembly may separate, resulting in oil leaks. Therefore, be sure to remove the service bolts and spacers from one camshaft bearing cap at a time.

HINT:

Make sure that the orientation of the straight pin, timing mark and paint mark of the camshaft are as shown in the illustration.

(b) Tighten the 10 bolts in the order shown in the illustration.

Torque:

16 N·m {163 kgf·cm, 12 ft·lbf}

8. INSTALL CAMSHAFT TIMING SPROCKET

(a) Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft slightly counterclockwise to release the chain sub-assembly.

NOTICE:

Do not turn the camshaft more than necessary.

*a	Paint Mark
*b	Timing Mark

(b) Align the paint mark with the timing mark to install the chain sub-assembly.

(c) Using SST, a 14 mm union nut wrench and a wrench, hold the hexagonal portion of the No. 2 camshaft and install the camshaft timing sprocket to the No. 2 camshaft.

SST: 09961-00950

Torque:

Specified tightening torque

54 N*m (551 kgf*cm, 40 ft.*lbf)

HINT:

Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
