25. REMOVE CAMSHAFTS
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, the portion of the cylinder head
P21196 receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, these
steps should be carried out.

(a) Remove the exhaust camshaft of the RH cylinder head.
(1) Align the timing marks (2 dot marks) of the camshaft
drive and driven gears by turning the camshaft with
a wrench.
