CAMSHAFT INSTALLATION

TEMPORARILY INSTALL CAMSHAFT TIMING SPROCKET ASSEMBLY

*a	Straight Pin
*b	Key Groove

Fit the camshaft timing sprocket assembly and camshaft together with the straight pin and key groove misaligned as shown in the illustration.

Turn the camshaft timing sprocket assembly clockwise while pushing it gently toward the camshaft. Push further at the position where the straight pin fits into the key groove.

Note:
Do not forcibly push in the camshaft timing sprocket assembly. This may cause the straight pin tip to damage the installation surface of the camshaft timing sprocket assembly.
Temporarily install the camshaft timing sprocket assembly with the bolt.
Make sure that the camshaft timing sprocket assembly gear is locked.

INSTALL CAMSHAFT

*a	Apply engine oil

Apply engine oil to the cams of each camshaft, the journals of the cylinder head sub-assembly and the top of each valve lifter.

*a	Paint Mark
*b	Timing Mark

Align the paint mark of the timing chain plate with the timing mark of the camshaft timing sprocket assembly and install the chain sub-assembly.

INSTALL NO. 2 CAMSHAFT

Set the No. 2 camshaft onto the cylinder head sub-assembly.

*1	No. 1 Camshaft Bearing Cap
*2	No. 2 Camshaft Bearing Cap

Place the No. 1 camshaft bearing cap and No. 2 camshaft bearing caps and tighten the bolts to the specified torque in the order shown in the illustration.

Note:

Install No. 1 camshaft bearing cap and No. 2 camshaft bearing caps with the front marks facing the front of the engine.

INSTALL CAMSHAFT TIMING GEAR

*a	Paint Mark
*b	Timing Mark

Align the paint mark of the chain plate with the timing mark of the camshaft timing gear and install the chain sub-assembly.

Install the camshaft timing gear to the No. 2 camshaft with the knock pin aligned with the pin hole.

*a	Hold
*b	Turn
*c	12 x 14 mm short offset wrench
*d	12 mm hexagon socket wrench
*e	Torque wrench with a fulcrum length of 260 mm (10.24 in.)
*f	12 x 14 mm short offset wrench with a fulcrum length of 100 mm (3.94 in.)

Using a wrench, hold the hexagonal portion of the No. 2 camshaft.

Using a 12 x 14 mm short offset wrench and 12 mm hexagon socket wrench, fully tighten the bolt.

Tip:
- This torque value is effective when 12 x 14 mm short offset wrench is parallel to the torque wrench.
- Be sure to align the 12 x 14 mm short offset wrench and torque wrench.
- The "with 12 x 14 mm short offset wrench (09031-1C530) and 12 mm hexagon socket wrench" torque value is effective when using a 12 x 14 mm short offset wrench with a fulcrum length of 125 mm (4.92 in.).
- The "with 12 x 14 mm short offset wrench (09031-1C530) and 12 mm hexagon socket wrench" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.24 in.).
- If using a torque wrench with a different length, or connecting the torque wrench and 12 x 14 mm short offset wrench at an angle, refer to the alternate torque values.

TIGHTEN CAMSHAFT TIMING SPROCKET ASSEMBLY

*a	Hold
*b	Turn
*c	Torque wrench with a fulcrum length of 260 mm (10.24 in.)
*d	SST with a fulcrum length of 100 mm (3.94 in.)

Using a wrench to hold the hexagonal portion of the camshaft, install the bolt using SST.
