NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, damage to the cylinder head or to the camshaft may result. To avoid this, the following steps must be carried out.

a. Align the camshaft drive and driven gears timing marks (1 dot mark each) by turning the camshaft with a wrench.

b. Secure the exhaust camshaft sub gear to the main gear

b. Secure the exhaust camshaft sub gear to the main gear with a service bolt.

Recommended service bolt:

Torque: 5.4 Nm (55 kgfcm, 48 in.lbf)

Torque: 5.4 Nm (55 kgfcm, 48 in.lbf)

HINT: When removing the camshaft, make certain that the torsional spring force of the sub gear has been eliminated by installation of the service bolt.

c. Uniformly loosen and remove the 10 bearing cap bolts in

c. Uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration. Remove the 5 bearing caps and the No. 3 camshaft.

NOTICE:

  • Do not pry out the camshaft.

  • Be careful not to damage the portion of the cylinder head receiving the shaft thrust.

23. REMOVE No.4 CAMSHAFT SUB−ASSY

23. REMOVE No.4 CAMSHAFT SUB−ASSY

a. Uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration. Remove the 5 bearing caps and the No. 4 camshaft.

NOTICE:

  • Do not pry out the camshaft.

  • Be careful not to damage the portion of the cylinder head receiving the shaft thrust.

b. Remove the oil seal from the No. 4 camshaft.

  2. REMOVE CAMSHAFT SUB GEAR No.3

  3. INSTALL CAMSHAFT SUB GEAR No.3

  4. INSTALL CAMSHAFT TIMING GEAR ASSY

  5. INSTALL No.4 CAMSHAFT SUB−ASSY

NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being installed. If the camshaft is not kept level, damage to the cylinder head or to the camshaft may result. To avoid this, the following steps must be carried out.

  1.  Apply new engine oil to the thrust portion and journal of the camshaft.

  2.  Place the No. 4 camshaft at a 90 angle of the timing mark (1 dot marks) on the cylinder head.

  3. Apply MP grease to a new oil seal lip.

d. Install the oil seal to the camshaft.

d. Install the oil seal to the camshaft.

NOTICE:

  • Do not turn over the oil seal lip.

  • Insert the oil seal until it stops.

  1. Remove any old packing material from the contact surface.

  2. Apply seal packing to the No. 1 bearing cap as shown in the illustration.

    Seal packing: Part No. 08826−00080 or equivalent

NOTICE:

  • Install the No. 1 bearing cap within 5 minutes after applying seal packing.

  • Do not expose the seal to engine oil for at least 2 hours after installing.

  1.  Install the 5 bearing caps in their proper locations.

  2. Apply a light coat of engine oil on the threads of the bearing cap bolts.
