4. DISASSEMBLY/ASSEMBLY MOTOR
Once the wet end has been disassembled from the motor, the motor disassembly can begin.
The preparations and caution for Wet Disassembly also apply to motor disassembly.
4.1 FAN END DISASSEMBLY
The following instructions are applicable to the motor being removed from its foundation and
placed securely in a horizontal position.
4.1.1. FAN SHROUD REMOVAL
4.1.1.1. Install a ½” eyebolt in the threaded hole by the grease fitting or wrap a lifting
strap around the fan shroud (301). Using an overhead crane, place the eye bolt
or lifting strap in light tension.
4.1.1.2. Remove the three socket head cap screws (318) from around the fan shroud
(301).
4.1.1.3. Pull the fan shroud (301) off of the motor. There may be a slight interference
between the fan shroud (301) and the motor. If so, use a rubber mallet to gently
tap the fan shroud to remove it.
4.1.2. FAN REMOVAL
4.1.2.1. Using the 65mm torque wrench adapter (P/N 0665931), or adjustable head
(hook style) spanner wrench or a bar and mallet, remove the bearing locknut
(308). The bearing locknut will have to be replaced.
4.1.2.2. Hold the fan (400) by the center metal hub and pull it and the hardened washer
(309) off of the drive shaft (5).
4.1.3. SENSOR AND SENSOR COVER REMOVAL
4.1.3.1. Before removing the sensor cover (31) from the bearing cap (14), review the
match marks on the two parts so they can be re-assembled with the correct
relative alignment. The mark scribed on the bearing cap should line up with the
scribed arrow on the sensor cover.
4.1.3.2. Remove the three socket head cap screws (319) from the bearing cap (14) and
the set screw (315) from the shutter (406). The sensor cover is now loose and
can be removed from the bearing cap (14). The wire from the sensor may have
to be loosened in order to pull the sensor cover (310) over the end of the drive
shaft (5).
