. . .
(2) After aligning the timing mark on the oil pump sprocket,’
remove the cylinder block plug and insert a Phillips screw-
driver with a diameter of 8 mm in.), and check
be sure that the screwdriver goes mm (2.36 in.)
or more. If the screwdriver will only go in 20
25 mm
in,) before striking the counterbalance shaft,
turn the sprocket once, realign the timing mark and check
that the screwdriver goes in 60 mm (2.36 in.) or mo re.
Do not take out the screwdriver until the timing ‘b elt is
installed.
(3) Install the timing belt so as not to be
the sprockets, by the following procedure.

(5) Screw the tool into the engine left support until
its end makes contact with the tensioner
At that
point, screw the tool in
and then remove
the set wire attached to the
tensioner.
(6) Remove the tool.
(7) Tighten the center bolt to the specified torque .

BELT TENSION ADJUSTMENT
(1) After turning the crankshaft
of a revolution counter-
clockwise, turn it clockwise until the timing marks are
aligned.
(2) Loosen the tension pulley fixing bolt, and then use the
special tool and a torque wrench to
the fixing
bolt to the specified torque while applying tension to the
timing belt.,
Standard value:
3.5 Nm (2.6
belt tension torque> ,
Caution
When tightening the fixing bolt, do not let the ten sion
pulley turn with the bolt.
(3) Turn the crankshaft two revolutions ‘clockwise so that
the timing marks are aligned.
leaving it for 15 min-
utes, measure the amount of protrusion of the auto ten-
sioner.
Standard value (A): 3.8-4.5 mm in.)
(4) If the amount of protrusion is outside the standard value,,
repeat the operation in steps ‘(1) to, (3).
(5) Check again that the timing marks of each sproc ket are
aligned.

TIMING BELT INSTALLATION
Install timing belt
by the procedure.
(1) Ensure that crankshaft sprocket “B” timing mark and the
counterbalance shaft sprocket timing mark are align ed.
(2) Fit timing belt
over crankshaft sprocket “B” and the
silent shaft sprocket. Ensure that there is no slac k in
the belt.
BELT TENSION ADJUSTMENT
Adjust the tension of timing belt by the following procedure.
(1) Temporarily fix the timing belt tensioner such that
the center of the tensioner pulley is to the left a nd above
the center of the installation bolt, and temporarily attach
the tensioner pulley so that the flange is toward t he front
of the engine.,
(2) Holding the timing belt “B” up with your
in the direction of the
belt so that the tension side of the belt is taut.
Now tighten
the bolt to fix the tensioner.. ,
Caution
When tightening the ensure that the
pulley shaft does not rotate, with
