Place the compressor/evaporator fan/alternator belt in
the compressor pulley and check to see that it is cen-
tered in the slot on the left side of the idler bracket. If
not, adjust the position of the left evaporator fan pulley
on the fan shaft so the belt is centered in the slot. Adjust
the compressor/evaporator fan/alternator belt to the
proper tension after it is centered in the slot.
4.
Adjust the compressor/jackshaft (electric motor) belt to
the proper tension. The belt tension should be set at a
reading of 64 to 70 on the Thermo King Belt Tension
Gauge P/N 204-427. If the Thermo King Belt Tension
Gauge is not used, the belt should deflect 1/2 in.
(13 mm) at the center of the longest span.
The engine/compressor belt tension should be set at a
reading of 70 to 80 on the Thermo King Belt Tension Gauge
P/N 204-427.
