Preventive Maintenance; Bearing Replacement - DERRICK HYPERPOOL SHAKER Maintenance & Operation Manual

PREVENTIVE MAINTENANCE

Routine preventive maintenance will ensure maximum life for the vibrator motor. While the
maintenance schedule in this section is flexible, modifications should be based on operating
experience at your facilities.
A maintenance log will help establish and monitor a service schedule that is correct for your
equipment. The maintenance log should contain the following information:
•
Motor model and serial number from motor data plate
•
Power requirements
•
Voltage reading across L1 to L2, L1 to L3, and L2 to L3
•
Amperage reading across L1 to L2, L1 to L3, and L2 to L3
WARNING! TO AVOID SERIOUS PERSONAL INJURY BE SURE EQUIPMENT
IS LOCKED OUT, TAGGED OUT, AND DE-ENERGIZED PRIOR TO
PERFORMING MAINTENANCE AND/OR ADJUSTMENTS.
Using a water hose, clean process material from exterior of
motor case*.
Inspect motor cable for signs of deterioration or damage.
Using a torque wrench; verify that motor mounting bolt torque
is in accordance with torque listed in Motor Removal and
Installation.
* The vibrator motor is designed to dissipate heat through the motor case. Buildup of process
material on the motor case exterior prevents proper heat dissipation and may cause the motor
to overheat.

BEARING REPLACEMENT

The following bearing replacement procedure applies only to SGX motors that are no longer
under warranty. During the warranty period the motor is not to be opened for any reason, as this
will void the warranty. Contact the Derrick Service department for assistance if a motor fails while
under warranty.
NOTE! All warranties, whether stated or implied, will be void if the Derrick
motor is opened during the warranty period.
Materials Required
The bearing replacement kits shown below contain the bearings and associated components
required for both ends of the motor. Derrick recommends replacement of bearings as a set.
Failure to replace both bearings may result in premature failure of the newly installed bearing.
