(b) Secure the exhaust camshaft sub±gear to the driven
gear with a service bolt.
Recommended service bolt:
Thread diameter 6 mm
Thread pitch 1.0 mm
Bolt length 16 ± 20 mm (0.63 ± 0.79 in.)
HINT: When removing the camshaft, make certain that
the torsional spring force of the sub±gear has been
eliminated by the above operation. 32. REMOVE CYLINDER HEAD COVERS

34. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the. camshaft is
small, the camshaft must be held level while it is being re-
moved. If the camshaft is not kept level, the portion of the
cylinder head receiving 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. Remove exhaust camshaft of RH cylinder head

drive and driven gears by turning the camshaft with a
wrench.
