16. INSTALL NO.2 TIMING BELT COVER
(a) Install the gasket to the timing belt cover.
(b) Install the timing belt cover with the eight bolts.
HINT: Use the bolts indicated by A, B and C.
17. INSTALL SPARK PLUGS (See page IG±11 )
Torque: 180 k9±cm (13 ft±Ib, 18 N±m)
14. CHECK VALVE TIMING
(a) Turn the crankshaft pulley two revolutions from TDC
to TDC.
HINT: Always turn the crankshaft clockwise.
(b) Check that each pulley aligns with the timing marks as
shown in the figure.
If the marks do not align, remove the timing belt and
reinstall it.
15. INSTALL ENGINE RH MOUNTING BRACKET

28. REMOVE NO. 3 TIMING BELT COVER
Remove the four bolts and belt cover.
HINT:
wSupport the belt so the meshing of the crankshaft timing
pulley and timing belt does not shift.
wBe careful not to drop anything inside the timing belt cover.
wDo not allow the belt to come into contact with oil, water or
dust. 24. REMOVE DELIVERY PIPE AND INJECTORS
(See steps 3 and 7 on page FI±89)
25. REMOVE SPARK PLUGS (See page IG±6)
26. REMOVE CAMSHAFT TIMING PULLEY
(See steps 2 to 14 on pages EM±23 and 25)
27. REMOVE NO. 1 IDLER PULLEY AND TENSION SPRING
(See step 18 on page FI±26)
30. REMOVE CAMSHAFTS
HINT: 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,
causing the camshaft to seize or break. To avoid this, the fol-
lowing steps should be carried out.
A. Remove exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10 ± 450
BTDC of camshaft angle.
HINT: The above angle helps to lift the exhaust camshaft level
and evenly by pushing No. 2 and No. 4 cylinder cam lobes of
the exhaust camshaft to their valve lifters.29. REMOVE CYLINDER HEAD COVER
Remove the four nuts, grommets, head cover and gasket.
HINT: Arrange the grommets in correct order, so that they
can be reinstalled into their original positions. This minimizes
any possibility of oil leakage due to reuse of grommets.
