Note:
Check for vertical alignment of
the motor pulley. To do this, simply
turn the motor several times and
check to you see if the belt is aligned
with the big pulley ( one way bearing
pulley ). If the belt is riding too high,
simply loosen up the motor pulley
and drop it just a little bit, if it is
riding too low, loosen up the motor
pulley and raise it a bit.
