The poly-link belt is placed so that the tab
ends of the links are facing inward, toward
the pulleys.
Wrap new belt as shown in
Figure 5-3
, and
pull it tight around the pulleys, ensuring that
the arrow indications on the belt face the
same direction as the compressor pulley
arrow(s).

the last two holes of one end of
the belt with two tabs of the other
end, matching links as shown in
[

6. Use a marker to place an
identifying mark where the
excess link begins.
7. Once the belt is sized correctly,
the excess overlapping link(s) will
need to be removed before
assembling the sized belt into a
completed loop. Follow the
procedure given in
