This is the Tension / Frequency limits for both the belts. The Frequency is a function of the length of span so span of the belt they measure
is very important. For The clutch belt, they have to measure between the motor pulley and the clutch tensioner pulley And again for the
fan belt they have to measure between the motor pulley and the fan drive tensioner.
SLX units have two automatic tensioning polygroove belt systems, in order to drive the compressor and the evaporator fanshaft. The
lower polygroove belt runs from the engine/compressor to the intermediate jackshaft (or electric motor, depending on the unit model).
The upper polygroove belt links the intermediate jackshaft to the evaporator fanshaft, incorporating other belt driven components such as
the condenser blowers and the alternator
