Page 12

G. TUMBLER BEARING AND PULLEY ARRANGEMENT

The tumbler bearing and the pulley arrangement is located (viewing from the rear of the dryer) approximately at the upper center of the dryer. The arrangement consists of a pulley, bearing platform, and bearing, which serve to adjust, drive, and support the tumbler.

H. 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 idlers 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.

I. 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. On non-reversing dryers, 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 tumbler through the lint screen and out the exhaust. On reversing dryers, there are two (2) motors, one (1) for the drive and one (1) for the blower.
