MAINTENANCE
12.1
Record Keeping
It is suggested that a record is kept of operational data and that all servicing
maintenance is recorded. Maintenance data to be recorded should include details
of inspections and any parts replaced.
12.2
Fan and Motor Replacement
Fan and/or motor replacement requires removal of the fan from the top
plate. Lock out electrical power to the motor. Remove the mounting bolts and lift
the fan assembly away. By removing the appropriate bolts, the fan wheel can be
removed and replaced. The fan wheel must be removed for motor replacement. A
wheel puller may be required for replacement of the fan wheel.
To replace the Shaker Motor, follow the following steps: (Figure 9)
1. Remove motor terminal cover and disconnect wires. Remove cable
connector and wires from the motor.
2. Loosen bearing locking collar as follows:
a. Loosen set screw.
b. Rotate bearing so that the hole without the set screw faces you.
Place a punch in hole and sharply tap punch in a CCW direction. If
collar doesn’t loosen, sharply tap in a CW direction to loosen. (Repeat
if necessary.)
3. Loosen and remove motor mounting bolts.
4. Lift and remove motor. Eccentric (on motor shaft) should disengage from
bore of bearing. Bearing will remain in flanges.
5. Remove eccentric from shaft by loosening two (2) set screws.
To reinstall, reverse above procedure.
NOTE: Install motor with electrical terminals accessible.
After reinstalling all parts, rotate bearings several turns by hand to ensure
equally free movement throughout rotation.
