(2) Secure the exhaust camshaft sub±gear to drive
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 ± 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) Remove the 2 bolts and rear bearing cap.
(4) Uniformly loosen and remove the 6 bolts on the
No.1, No.2 and No.4 bearing caps in several
passes, in the sequence shown.
NOTICE:
Do not remove the No.3 bearing cap bolts at this stage.
(5) Remove the No.1, No.2 and No.4 bearing caps.
(6) Alternately loosen and remove the 2 bolts on the
No.3 bearing cap.
HINT:

As the 2 No.3 bearing cap bolts are loosened, make sure
that the camshaft is lifted out straight and level.

If the camshaft is not being lifted out straight and level, re-
tighten the 2 No.3 bearing cap bolts. Then reverse the or-
der of above steps from (6) to (1) and reset the knock pin
of the intake camshaft at 10 ± 45° BTDC, and repeat
steps from (2) to (6) once again.
NOTICE:
Do not pry on or attempt to force the camshaft with a tool
or other object.
(7) Remove the No.3 bearing cap and exhaust cam-
shaft.

29. REMOVE OIL DIPSTICK AND GUIDE
(a) Remove the bolt holding the dipstick guide to the LH cylin-
der head.
(b) Pull out the dipstick guide together with the dipstick from
the No.1 oil pan.
(c) Remove the O±ring from the dipstick guide.
30. REMOVE CYLINDER HEAD COVERS
Remove the 8 bolts, cylinder head cover and gasket. Remove
the 2 cylinder head covers.
31. REMOVE 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 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 (2 dot marks) of the camshaft
drive and driven gears by turning the camshaft with
a wrench.
(2) Secure the exhaust camshaft sub±gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 ± 20 mm (0.63 ± 0.79 in.)

several passes, in the sequence shown.
(c) Remove the 5 bearing caps and intake camshaft.
(d) 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.
HINT:

Arrange the camshafts in the correct order.

Arrange the bearing caps in the correct order.
33. DISASSEMBLE EXHAUST CAMSHAFTS
(a) Mount the hexagonal wrench head portion of the cam-
shaft in a vise.
NOTICE:
Be careful not to damage the camshaft.
