e.
Check
the belt
and
pulley
alignment
of the
compressor
and/or
alternator
by
the
following
method:
1.
A
datum
line
must
be established
for
checking
belt
and pulley
alignment.
A
nominal
dimension
must be
established
between
the forward
edge
of each
belt
and the
forward
machined
surface
of the ring
gear. This
dimension
should
be taken
at the
ring gear
assembly
where
the belts
are
in
their
sheaves.
The
amount
of misalignment
can
then
be
determined
at
the other
pulley
sheaves
by using
a
stiff straightedge
of
sufficient
length
to
extend
from
the
front
of
the ring
gear
to the
component
sheaves.
NOTE
Insure
adequate
ring
gear
surface
contact
to
provide
a solid
base
for the
straightedge.
