Timing Belt Cover
Install the left and right timing belt covers.
Tightening torque:
7—10 Nm (70—100 cm-kg, 61—87 in-lb)
Crankshaft Pulley
Install the crankshaft pulley.
Tightening torque:
23—32 Nm (2.3—3.3 m-kg, 17—24 ft-lb)
Valve Clearance
1. Set the No.1 cylinder to compression TDC.
2. Measure the valve clearance at No.1, No.2 (intake),
and No.1, No.3 (exhaust).
Clearance (cold engine)
IN : 0.20—0.30 mm (0.008—0.012 in)
EX: 0.30—0.40 mm (0.012—0.016 in)
3. If the valve clearance is not within the specifica-
tion, adjust the valve clearance.
(1) Face the intake cam lobe straight upward.
(2) Move the tappet so that its notch is at the man-
ifold side.
(3) Press the tappet down until the adjusting disc
is accessible with the SST.
(4) Take out the adjusting disc.

76G01C-201
(5) Select an appropriate disc depending on the
valve clearance measured. And install it.
Example (intake valve):
Thickness of original adjusting disc + (measured
clearance — standard clearance) = thickness of
new adjusting disc.
4.00 + (0.30 - 0.25) = 4.05 mm
0.157 + (0.012 - 0.010) = 0.159 in
Note
a) The disc thickness is indicated by the num-
ber marked on the disc. For example, 3825
means 3.825 mm (0.1056 in).
b) Adjusting discs are available in 25 different
thicknesses within the 3.40—4.60 mm
(0.134—0.181 in) range, at intervals of 0.05
mm (0.002 in).
(6) Inspect the clearance again.
4. Set the No.4 cylinder to compression TDC.
5. Measure and adjust the valve clearance at No.3,
No.4 (intake), and No.2, No.4 (exhaust) in the same
way.
