Drive Belt System Description
The drive belt system consists
of
the following components:
• The drive belt
•
The drive belt tensioner
• The drive belt idler pulley
•
The crankshaft balancer pulley
•
The accessory drive component mounting brackets
• The accessory drive components
• The power steering pump, if belt driven
• The generator
• The AlC compressor, if equipped
• The engine cooling fan,
if
belt driven
• The water pump, if belt driven
• The vacuum pump, if equipped
• The air compressor,
if
equipped
The drive
belt system may use one belt or two belts. The drive belt is thin so that it can bend backwards
and has
several ribs to match the grooves
in
the pulleys. There also
may
be a V-belt style belt used to
drive certain accessory drive components.The drive
belts are made
of
different types
of
rubbers
(chloroprene or EPDM) and have different
layers or plys containing either fiber cloth or cords for
reinforcement.
Both sides
of
the drive belt may
be
used to drive the different accessory drive components. When the
back side
of
the drive belt is used to drive a pulley, the pulley is smooth.
The drive
belt
is
pulled
by
the crankshaft balancer pulley across the accessory drive component pulleys.
The spring loaded drive belt tensioner keeps constant tension on the drive belt to prevent the drive belt
from slipping. The drive belt tensioner arm will move when loads are applied to the drive belt by the
accessory drive components and the crankshaft.
the
drive belt system
may
have an idler pulley, which
is
used to add wrap
to
the adjacent pulleys. Some
systems use an
idler pulley in place
of
an accessory drive component when the vehicle
is
not equipped
with the accessory.
