Adjustment of Belt Tension
Warning
Be sure to stop the engine before adjusting
the belts.
Important
Before making sure of belt tension, rotate the
belt several times.
If the belt becomes slack due to frequent use, it
may jump or slip.
In addition, if it is overtightened, it may wear
prematurely.
If necessary, adjust it, and always check the
belt for appropriate tension.
Adjustment of Fan Belt
Warning
Be sure to stop the engine before inspecting
or adjusting the fan belt.
Warning
If a cover is removed due to inspection or
adjustment, be sure to reinstall it in its original
location.
Important
A slacking or damaged fan belt will cause
overheating or lack of battery charge.
Adjust or replace the belt.
For fan belt adjustment, follow either of the
methods below.
Adjustment on the basis of belt slack
deviation when applying a specified load to
a specified place
Press the middle of the belt with your
finger to check the belt tension.
The belt tension is appropriate when the
belt slacks by approximately 10.0 - 12.0
mm (0.39 - 0.47 in) when you apply a
force of 98 N (10 kgf) to the belt at the
middle point between the pulleys.
If the belt tension is inappropriate, loosen
bolts A and B for securing the alternator,
and then move the alternator to adjust
the tension.

Adjustment to suitable belt tension force by
using sonic type tension meters at a
specified point
Important
Perform correct measurement in accordance
with the operations manual of the equipment
being used for tension measurement.
Important
Perform measurement immediately after
mounting the belt, when the pulley is not
rotating.
Measure belt tension force by using a
sonic type tension meter.
For measurement position and distance
between pulleys, see diagram below.
Here is the suitable belt tension force.
Adjustment
237 - 403 N
Replacement
460 - 680 N
If the belt tension is inappropriate, loosen
bolts A and B for securing the alternator,
and then move the alternator to adjust
the tension.
