REMOVE NO.3 CAMSHAFT SUB-ASSY

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

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

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

Torque: 5.4 N.m (55 kgf.cm, 48 in..lbf)

Recommended service bolt

SERVICE BOLT DIAMETER

Thread diameter	6 mm
Thread pitch	1.0 mm
Bolt length	16 to 20 mm

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.

Using several steps, loosen and remove the 10 bearing cap bolts uniformly in the sequence shown in the illustration. Remove the 5 bearing caps and No. 3 camshaft.

NOTE:

Do not pry out the camshaft.
Be careful not to damage the contact surface of the cylinder head that receives the shaft thrust.

NOTE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while being installed. If the camshaft is not kept level, the cylinder head or camshaft may be damaged. 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 multi-purpose grease to a new oil seal lip.

4. Install the oil seal to the camshaft.
  NOTE:
  - Do not turn over the oil seal lip.
  - Insert the oil seal until it stops.
5. Remove any old packing material from the contact surface.
