1. CAM CARRIER RH

1. Insert the steel rods into ST, and set the engine so that the camshaft RH is facing up.

CAUTION:

• If the engine is standing on one side without inserting the steel rod into ST, engine may lose balance and fall down. Be sure to insert the steel rod into ST to extend the length.

• Use the steel rod with enough strength.

• Be careful not to pinch the engine harness with ST.

2. Apply engine oil to the valve shim and the roller rocker arm pivot, and install the valve shim and the roller rocker arm pivot to the cylinder head RH.

3. Apply engine oil to the O-ring and the roller rocker arm, and install the O-ring and the roller rocker arm to the cylinder head RH.

NOTE:

Use new O-rings.

4. Apply liquid gasket to the mating surface of cam carrier RH as shown in the figure.

NOTE:

• Before applying liquid gasket, degrease the old liquid gasket seal surface of the cylinder head RH and cam carrier RH.

• Install within 5 min. after applying liquid gasket.

Liquid gasket:

THREE BOND 1217G (Part No. K0877Y0100), THREE BOND 1217H or equivalent

Liquid gasket applying diameter:

3.0±0.5 mm (0.1181±0.0197 in)

(A)	Range A	(D)	Liquid gasket applying position of mating surfaces of range A	(G)	0±0.5 mm (0±0.0197 in)
(B)	φ18 mm (0.7087 in)	(E)	φ3.0±0.5 mm (0.1181±0.0197 in)	(H)	Chamfer edge
(C)	Liquid gasket applying position of mating surfaces other than range A	(F)	1 mm (0.0394 in) or less

5. Install the cam carrier RH to the cylinder head RH.

(1) Mount the cam carrier RH, then tighten all bolts with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.

NOTE:

Set the intake camshaft RH and the exhaust camshaft RH to the zero-lift position.

(2) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.

(3) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.

(4) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.

(5) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.

(6) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.

(7) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.

NOTE:

After tightening, if the liquid gasket is squeezed out onto the seal surface of the chain cover, completely remove any squeezed-out liquid gasket.

6. Set the part so that the intake manifold is on the upper side.

7. Install the cam sprocket RH. Cam Sprocket > INSTALLATION

NOTE:

This procedure is required only when the cam carrier RH is removed for disassembly.

8. Check the cam clearance. Cam Clearance > INSPECTION

9. Install the timing chain RH. Timing Chain Assembly > INSTALLATION

10. Secure the engine harness to the cam carrier RH with a clip.

11. Install the rocker cover RH. Rocker Cover > INSTALLATION

12. Install the water pipe assembly RH. Water Pipe Assembly > INSTALLATION

13. Install the fuel injector RH. Fuel Injector > INSTALLATION

14. Install the chain cover. Chain Cover > INSTALLATION

15. Install the engine to the vehicle. Engine Assembly > INSTALLATION

2. CAM CARRIER LH

1. Insert the steel rods into ST, and set the engine so that the camshaft LH is facing up.

CAUTION:

• If the engine is standing on one side without inserting the steel rod into ST, engine may lose balance and fall down. Be sure to insert the steel rod into ST to extend the length.

• Use the steel rod with enough strength.

• Be careful not to pinch the engine harness with ST.
