Fig. 156 Testing Alternator Belts Using SE-2312 Gauge
To establish tension of a loose belt, apply SE-2312
gauge to the belt and make the adjustment. Tighten belt until
proper area for the belt is indicated at the index mark on the
gauge. Lock the adjustment and recheck belt tension.
Readjust as necessary.
When using the SE-2312 belt tension guage,
remember to set new belts (belt with less than two minutes
running time) to the NEW area on the gauge face and used
belts (more than two minutes running time) to the USED area
on the gauge.
NOTE: Where the SE-2312 belt tension gauge is
not available or cannot be used because of
interference with fan shroud, accessories or
close clearances, a deflection check can be
made. Depress the belt at a point midway
between the water pump and alternator pulleys.
One-half inch (2") deflection is considered
acceptable as a final setting after the belt has
been operated for a short period of time.
The air or freon compressor and power steering or
air pump belts are adjusted in a similar manner.
