. ADJUSTMENT OF TIMING BELT TENSION
(1) After turning the crankshaft turn counterclockwise,
turn it clockwise to move the No. 1 cylinder to top dead
center.
(2) Loosen the center bolt, and then, as shown in the
illustration, attach the special tool and a torque wrench
and apply a torque of 2.6-2.8 Nm If
the body interferes with the special tool and the torque
wrench, use a jack to slightly raise the engine assembly.
NOTE
Use a torque wrench that is capable of measurement
of 0- 3 Nm (0- 2.2
(3) Holding the tensioner pulley with the special tool
and
torque wrench, tighten the center bolt to specification.
(4) Screw the tool into the engine left support bracket until
its end makes contact with the tensioner arm. At that
point, screw the tool in some more and then remove the
set wire attached to the auto tensioner.
(5) Remove the tool.
(6) Rotate the crankshaft two complete turns clockwise
and leave it as is for about 15 minutes. Then, measure
the auto tensioner protrusion “A” (distance between
the tensioner arm and auto tensioner body) to ensure
that it is up to specification.
Standard value: 3.8-4.5 mm in.)
If it is out of specification, repeat steps (6) through (11)
until the specified value is obtained.
(7) If the clearance between the tensioner arm and the
auto tensioner body cannot be measured (when the
engine is being mounted, etc.), the following proce-
dures can be used to substitute for the ordinary method
of measurement.
the tensioner arm.
From that point of contact, further screw in the tool.
tensioner body is caused to move backward and the
tensioner arm contacts the auto tensioner body.
Check to be sure that the amount that the tool has
been screwed in (when the push rod moves back-
ward) is the standard value.
Standard value: 3 turns
