When removing the camshaft, mark certain that the torsional
spring force of the sub±gear has been eliminated by the above
operation.
(3) Uniformly loosen and remove the 10 bearing cap
bolts, in several passes, in the sequence shown.
(4) Remove the 5 bearing caps and intake camshaft.
(b) Remove the exhaust camshaft.
(1) Uniformly loosen and remove the 10 bearing cap
bolts, in several passes, in the sequence shown.
(2) Remove the 5 bearing caps, oil seal and exhaust
camshaft.
32. REMOVE CAMSHAFTS OF LH CYLINDER HEAD
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be held level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the intake camshaft.
(1) Align the timing marks (1 dot mark) of the camshaft
drive and driven gears by turning the camshaft with
a wrench.

5. 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.
