5.
Apply 4.3 to 8.7 N (1 to 1.9 lb) of pressure at point
(X).
The total deflection should not exceed 2.75 mm
(0.10 inch).
Replace the belt if the total deflection exceeds
1.5 mm (0.06 inch). Refer to“Adjustment” for more
information.
6.
Install lower cover (8) and install top cover (2).
Tighten bolt (7) and bolt (9) to a torque of 12 N·m
(106 lb in). Tighten bolt (4) and bolt (1) to a torque
of 12 N·m (106 lb in).
Adjustment
The alternator belt is a toothed belt. The belt tension
is not adjustable. The belt does not require a preload.
Light tension will ensure that the belt is a snug fit on
the pulleys.
Replace the Belt
Isolate the electrical supply to the engine.
1.
Refer to “Inspection” for removing the belt guard
covers.
2.
Loosen bolt (6) and loosen bolt (11). Push
alternator (5) towards engine. If necessary,
remove bolt (11) from link (10) to allow more
moment.
3.
Remove belt (13) and discard. Install new belt and
ensure that the belt is located over pulley (12) and
pulley (14). Ensure that new toothed belt is located
into the pulley (12) and pulley (14).
4.
If necessary, install bolt (11) and tension the new
belt. Refer to “Inspection” for more information.
5.
When required tension is correct, tighten bolt (11)
to a torque of 47 N·m (34 lb ft). Tighten bolt (6) to
a torque of 70 N·m (51 lb ft). Then, install the
cover guards, refer to “Inspection” for more
information.
When all checking of the belt or tensioning of the belt
are completed and the all guards cover are installed,
restore the electrical power.
