Check And Adjustment Of Tension (Deflection Amount) Of V-Belt For Alternator - PERODUA 2005 Myvi M300 Service Manual

1-2-7 CHECK AND ADJUSTMENT OF TENSION (DEFLECTION AMOUNT) OF V-BELT FOR
ALTERNATOR
(1) Check
1. Check the V-ribbed belt for cracks, deterioration and significant wear.
2. Check the tension of the V-ribbed belt, using a belt tension gauge.
NOTE
• The check can be performed by measuring the deflection amount of the V-belt.
Specified value
Tension value (N{kgf})
Deflection amount (mm) (Pushing force 100N{10.2kgf})
NOTE
When checking the deflection amount of the belt, push a point between the water pump pulley and
•
alternator pulley or crankshaft pulley and A/C pulley with a force of 100 N (10.2 kgf). Under this
condition, neasure the deflection amount.
In cases where the tension is measured after the belt has been assembled, the measurement
•
should be performed after cranking two turns.
When the belt is replaced with a new one, the belt tension should be adjusted to the mid-value of
•
the specified value for "When a new part is installed."
As regards the belt that has been used for more than five minutes, ensure that the belt tension
•
conforms to the specified value for "During inspection."
• When the belt that has been used for more than five minutes is assembled, the belt tension should
be adjusted to the mid-value of the specified value for "During inspection."
