2 2 . RE MO V E CAMS HAFTS
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
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 exhaust camshaft
(1)
Bring the service bolt hole of the driven sub--gear
upward by turning the hexagon wrench head por-
tion of the exhaust camshaft with a wrench.
(2)
Secure the exhaust camshaft sub--gear to the main
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 sure 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 camshaft.
HINT:
If the camshaft is not being lifted out straight and level, reinstall
the No.3 bearing cap with the 2 bolts. Then alternately loosen
and remove the bearing cap bolts with the camshaft gear pulled
up.
NOTICE:
Do not pry on or attempt to force the camshaft with a tool
or other object.
