1. Use a belt tension gauge to check that the belt tension
is at the standard value at a point half-way between the
two pulleys (indicated by an arrow in the illustration).
In addition, press this section with a force of 98 N and
check that the amount of belt deflection is at the standard
value.
Standard value:
Items When
checked
When a
used belt is
installed
When a new
belt is
installed
Tension N 392-588 441-539 637-833
Deflection

2. If the tension or deflection is outside the standard value,
adjust by the following procedure.
(1) Loosen tensioner pulley fixing nut A.
(2) Adjust the amount of belt deflection using adjusting
bolt B.
(3) Tighten fixing nut A.
Tightening torque: 25 Nm
(4) Check the belt deflection amount and tension, and
readjust if necessary.
