Camshaft Bearing

CAMSHAFT (RH)

INSTALL NO.2 CAMSHAFT

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 should be carried out.

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





b. Place the No 2 camshaft at a 90° angle of the timing mark (2 dot marks) on the cylinder head.
c. Apply MP grease to a new oil seal lip





d. Install the oil seal to the camshaft.

NOTICE:
^ Do not turn over the oil seal lip.
^ Insert the oil seal until it stops.

e. Remove any old packing material from the contact surface





f. 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 within 2 hours after installing.





g. Install the 5 bearing caps in their proper locations.
h. Apply a light coat of engine oil on the threads of the bearing cap bolts





i. Using several steps, tighten the 10 bearing cap bolts uniformly in the sequence shown in the illustration.
Torque: 16 Nm (163 kgf-cm, 12 ft. lbs.)
