Fan Motor Access and Removal
Always shut off electrical power to the tower fan motor prior to
performing any inspections that may involve physical contact with
the mechanical or electrical equipment in or on the tower. Lock out
and tag out any electrical switches to prevent others from turning
the power back on. Service personnel must wear proper personal
protective clothing and equipment.
The MD fan motors are located inside or outside the tower, depending
on the model. The MD5008 and MD5010 fan motor is located outside the
tower. The motor is fully accessed by removing the motor protection hood.
Remove motor protection hood and the drive belt by following the instruc-
tions in the Belt Tensioning
section.
The MD5008 and MD5010
motors are oriented with the
shaft up. The motor may
be hoisted by threading an
eye bolt into the motor shaft
and lifting with a hoist. To
remove the motor fastener
hardware, lift on the mo-
tor slightly with the hoist
to remove the weight from
the fasteners, loosen and
remove all hardware.
