J. Idler Bearing
(Viewing from the rear of the dryer.) The idler assembly
is located approximately on the lower left hand side of
the dryer. The idler assembly consists of one (1)
compound pulley. The idler’s main purpose is to reduce
the speed and increase the torque provided to the tumbler
bearing. Also, the idler assembly belt tension can be
adjusted. AD-15 thru AD-30 requires a 9” x 2-1/2”
pulley. AD-50 thru AD-75 requires a 14” x 3” pulley.
K. Drive Motor and Blower Motor
The drive motor is located on the back, approximately
lower center of the dryer. It sits on an adjustable base so
that the motor can be easily adjusted to the left or right,
up or down. The blower end of the motor is connected
to the impellor, a backward curved paddlewheel. The
impellor provides airflow in the dryer. It creates a
vacuum which pulls the hot air from the burner into the
basket through the lint screen and out the exhaust.
L. Temperature Sensors (Computer
Controls)
The temperature sensor used in a transducer that
converts heat into microamps that the computer board
then uses to calculate the temperature.
