HINT:
If re-using the belt and the installation mark is disappeared
from it, place a new installation mark on the timing belt to the
match the dot mark on the crankshaft timing pulley.
28. REMOVE NO.1 IDLER PULLEY AND NO.2 IDLER
PULLEY
(a) Using a 10 mm hexagon wrench, remove the bolt, the
No.1 idler pulley and the plate washer.
(b) Remove the bolt and the No.2 idler pulley.
29. REMOVE CRANKSHAFT TIMING PULLEY

7. REMOVE RH CYLINDER HEAD COVER
Remove the 9 bolts, the 9 seal washers and the cylinder head
cover.
8. REMOVE LH CYLINDER HEAD COVER
(a) Remove the oil dipstick for the transmission.
(b) Disconnect the PCV hose.
(c) Disconnect the engine wire clamp from the wire bracket
on the cylinder head cover.
(d) Remove the 9 bolts, the 9 seal washers and the cylinder
head cover.
9. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the timing marks of the camshaft timing pul-
leys and that of the timing belt rear plates are aligned.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.

10. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a feeler gauge, measure the clearance be-
tween the valve lifter and the camshaft.
Record the out-of-specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake
0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust
0.25 - 0.35 mm (0.010 - 0.014 in.)
(b) Turn the crankshaft 1 revolution (360°) and align the mark
as above (See procedure in step 9).
(c) Check only the valves indicated as shown. Measure the
valve clearance. (See procedure in step (a))
11. ADJUST VALVE CLEARANCE
(a) Remove the timing belt (See page EM-15).
(b) Remove the camshafts (See page EM-35).
(c) Remove the valve lifter and adjusting shim.
(d) Determine the replacement adjusting shim size according
to the following Formula and Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate the thickness of a new shim so that the
valve clearance comes within the specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim

Intake:
N = T + (A - 0.20 mm (0.008 in.))
Exhaust:
N = T + (A - 0.30 mm (0.012 in.))
Select a new shim with the closest thickness as
close as possible to the calculated value.
HINT:
Shims are available in 41 increments of 0.020 mm (0.0008 in.),
from 2.00 mm (0.0787 in.) to 2.80 mm (0.1102 in.).
(e) Place a new adjusting shim on the valve.
(f) Place the valve lifter.
(g) Reinstall the camshafts (See page EM-57).
(h) Reinstall the timing belt (See page EM-22).
(i) Recheck the valve clearance.
