INSTALLATION

Camshaft installation: Apply engine oil to the cylinder head at camshaft bearing location before installing the camshaft. Install the camshaft so that each valves is close to or in contact with “base circle” of cam lobe.


Note
• When the camshafts are positioned as shown in the figure, camshafts need to be rotated at a minimum to align with the timing belt during installation.

• Camshaft (RH) need not be rotated when set at the position shown in the figure. Intake camshaft (LH): Rotate 80° clockwise. Exhaust camshaft (LH): Rotate 45° counterclockwise.

Camshaft cap installation:

Apply liquid gasket sparingly to the cap mating surface.

Note

Do not apply liquid gasket excessively. Failure to do so may cause excess packing to come out and flow toward oil seal, resulting in oil leaks.


Liquid gasket:

Part No. 32005013

THREE BOND 1215 or equivalent


Apply engine oil to cap bearing surface and install the cap on camshaft as shown by identification mark (A).

Gradually tighten the camshaft cap in at least two stages in alphabetical sequence shown in the figure, and then tighten to specified torque.

Tightening torque:

T1: 10 Nm (1.0 kgf-m, 7.4 ft-lb)

T2: 20 Nm (2.0 kgf-m, 14.5 ft-lb)


Similarly, tighten the cap on exhaust side. After tightening the cap, ensure the camshaft rotates only slightly while holding it at “base” circle.

Tightening torque:

T1: 10 Nm (1.0 kgf-m, 7.4 ft-lb)

T2: 20 Nm (2.0 kgf-m, 14.5 ft-lb)


Camshaft oil seal installation: Apply grease to the new oil seal lips and press onto the front end of camshaft by using ST1 and ST2.

Note

Use a new oil seal.
