7) Remove the key on the blower (squirrel cage fan) shaft.
(a) Slide the blower (squirrel cage fan) off of the shaft.
NOTE: Install this key on to the fan shaft before installing the new blower (squirrel cage fan).8) To install blower (new squirrel cage fan) , reverse above procedure.
d) V-Belt Replacement
1) Discontinue electrical power to the dryer.
2) Loosen the bolts securing the blower (squirrel cage fan) motor.
(a) Ease off on the tension bolt.
3) Slide the blower (squirrel cage fan) motor forward.
4) Remove and replace V-belts.
5) Tighten and secure the tension bolt.
IMPORTANT: DO NOT OVERTIGHTEN V-BELTS.6) Using a straight edge, make certain that the motor pulley and V-belts a aligned straight.
7) Tighten and secure bolts from motor to motor base.
8) Reestablish electrical service to the dryer.
e) Fan (impellor) Shaft Replacement
The procedure to replace the Fan Shaft is the same procedure used to replace the Shrouded Pillow Block
Bearing (refer to previous pages (page 67 and page 68).
3. Blower (squirrel cage fan) Electrical Components
a) Blower (squirrel cage fan) Controls and Overloads
1) Thermal Magnetic Starter (TMS)
The thermal magnetic starter is used as a safety device to protect the motor from starting in a locked
rotor condition. The overload has a dial setting on the face of the device. To set the overload, refer to
your specific electrical diagrams. The overload is specifically designed for motor applications. It has
a current curve built into it so the initial high current draw by the motor will not trip the overload. On
the face of the overload, there are two (2) push buttons - "START" (Black or Tan - 1) and "STOP"
(Red - 0) - the overload has to be in the "START" mode for the motor to run.
