INSTALL CAMSHAFTS OF RH CYLINDER HEAD
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be held level while it is being installed. If the
camshaft is not level, the portion of the cylinder head re-
ceiving the shaft thrust may crack or be damaged, causing
the camshaft to seize or break. To avoid this, the following
steps should be carried out.
(a)
Install the exhaust camshaft.
(1)
Apply new engine oil to the thrust portion and jour-
nal of the camshaft.
(2)
Place the exhaust camshaft at 90
°
angle of timing
mark (2 dot marks) on the cylinder head.
(3)
Apply MP grease to a new oil seal lip.
(4)
Install the oil seal to the camshaft.
(5)
Remove any old packing (FIPG) material.
(6)
Apply seal packing to the No.1 bearing cap as
shown.
