MECHANICAL(H4DO) > Cam Carrier

INSTALLATION

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.

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. Install the fuel pipe RH and the fuel injector RH.

(1) Install the fuel pipe RH and the fuel injector RH, and install the bolts which secure the fuel pipe RH.

NOTE:

Use new O-rings, rubbers, seal rings and fuel injector holder.

Refer to “Fuel Injector” for fuel injector holder removal and installation. Fuel Injector > REMOVAL">

Tightening torque:

6.4 N·m (0.7 kgf-m, 4.7 ft-lb)

(2) Connect the quick connector to the fuel pipe RH.

CAUTION:

Check that there is no damage or dust on the quick connector. If necessary, clean the seal surface of the pipe.

When connecting the quick connector, make sure to insert it all the way in before locking the slider.

When it is difficult to lock the slider, check that the connector is fully inserted.

After locking the slider, check that the quick connector is securely connected.

NOTE:

Connect the quick connector as shown in the figure.

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.
