10.
SET NO.1 CYLINDER TO APPROX. 60
°
/ BTDC COM-
PRESSION
(a)
Turn the crankshaft pulley, and align its groove with timing
mark ”0” of the No.1 timing belt cover.
NOTICE:
Always turn the crankshaft clockwise.
(b)
Check that the timing marks (TDC mark) of the camshaft
timing pulleys are aligned with the timing marks of the
No.4 timing belt cover.
If not, turn the crankshaft 1 revolution (360
°
).
(c)
Turn the crankshaft pulley 60
°
counterclockwise to place
the sub timing mark (60
°
mark BTDC) on the crankshaft
pulley at the timing mark ”0” position of the No.1 timing
belt cover.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulleys (steps 11 to 17), thus
resulting damage. So, always set the crankshaft pulley at
the correct angle.
(d)
Check that the dot marks (60
°
mark BTDC) of the cam-
shaft timing pulleys are aligned with the timing marks of
the No.4 timing belt cover.
(e)
Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.
11.
