1) Installation of belt tensioner adjuster
(1) Insert stopper pin 1.5 mm (0.059 in) dia. into place
while pushing tension adjuster rod into body using a
press.
CAUTION:
Do not allow press pressure to exceed 9,807 N (1,000
kg, 2,205 lb).
Do not release press pressure until stopper pin is
completely inserted.
Push tension adjuster rod vertically.
Press-in the push rod gradually, taking three min-
utes or more.

(2) Align single line mark on right-hand exhaust cam-
shaft sprocket with notch on belt cover.

(Make sure double lines on intake camshaft and
exhaust camshaft sprockets are aligned.)

CAUTION:
Intake and exhaust camshafts for this DOHC engine
can be independently rotated with timing belts
removed. As can be seen from the figure, if intake and
exhaust valves are lifted simultaneously, their heads
will interfere with each other, resulting in bent valves.

B2M0698A
When timing belts are not installed, four camshafts
are held at the“zero-lift”position, where all cams on
camshafts do not push intake and exhaust valves
down. (Under this condition, all valves remain
unlifted.)
When camshafts are rotated to install timing belts,
#2 intake and #4 exhaust cam of left-hand camshafts
are held to push their corresponding valves down.
(Under this condition, these valves are held lifted.)
Right-side camshafts are held so that their cams do
not push valves down.
Left-hand camshafts must be rotated from the“zero-
lift”position to the position where timing belt is to be
installed at as small an angle as possible, in order to
prevent mutual interference of intake and exhaust
valve heads.
Do not allow camshafts to rotate in the direction
shown in the upper of figure as this causes both intake
and exhaust valves to lift simultaneously, resulting in
interference with their heads.

2) Installation of timing belt
Align alignment mark on timing belt with marks on sprock-
ets in the numerical order shown in figure. While aligning
marks, position timing belt properly.
CAUTION:
Ensure belt’s rotating direction is correct.
