5.2.1 BELT TENSION AND
ALIGNMENT
Rotational power from the engine is transmitted
to the blower through the belt drive. To obtain
efficient transmission of power and good belt life,
the belts must be properly tensioned and the
pulleys aligned.
Belts that are too tight will stretch and wear quickly
or overload the bearings on the input shaft or
blower; Belts that are too loose will not transmit
the required, power and will slip, overheat and
wear quickly. Pulleys that are not aligned will
result In rapid belt wear.
