Engine/Compressor/Jackshaft Belt Tension
Adjustments
1.
Place the engine/compressor belt in the idler pulley.
Make sure the belt is also placed in the engine pulley
and the compressor pulley.
2.
Turn the sprocket with a 7/8 in. wrench to tension the
belt. Tighten the pulley bolt with a 3/4 in. wrench when
the belt is at the proper tension. Use one of following
methods to check (or set) the belt tension.
a.
The belt tension should be set at a reading of 70 to
80 on the Thermo King Belt Tension Gauge P/N
204-427.
Install New Idler Assembly
1.
Idler Bracket
2.
Slot
3.
Sprocket
b.
The belt should deflect 1/2 in. (13 mm) at the
center of the longest (lower) span.
c.
Use a 7/8 in. crow’s foot attached to a 3/8 in.
torque wrench to turn the sprocket and obtain a
reading of 40 in-lb (4.5 N•m) on the torque wrench
for used belts and 45 in-lb (5.0 N•m) for new belts.
Tighten the pulley bolt while holding the sprocket
in this position. When using this procedure, the
pulley bolt must at first be loose enough to allow
the sprocket to rotate freely. If not, the reading on
the torque wrench will not produce the proper belt
tension.
