(a) Slowly turn the crankshaft 2 revolutions, and align the tim-
ing marks of the crankshaft timing pulley and oil pump
body.
NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks of the RH and LH timing pul-
leys with the timing marks of the No.3 timing belt cover as
shown in the illustration.
If the marks do not align, remove the timing belt and reinstall it.
(c) Remove the crankshaft pulley bolt.
11. INSTALL RH ENGINE MOUNTING BRACKET
Torque: 28 N´m (290 kgf´cm, 21 ft´lbf)
12. INSTALL NO.2 TIMING BELT COVER
(a) Check that the timing belt cover gasket has no cracks or
peeling, etc.
If the gasket has cracks or peeling, etc., replace it using these
steps:
Using a screwdriver and gasket scraper, remove all
the old gasket material.
Thoroughly clean all components to remove all the
loose material.
Remove the backing paper from a new gasket and
install the gasket evenly to the part of the timing belt
cover shaded black in the illustration.
After installing the gasket, press down on it so that
the adhesive firmly sticks to the timing belt cover.

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.)

HINT:
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.
