Disassembly
If it becomes necessary to disassemble this motor, care should be
taken not to damage the stator windings as the insulation may be
injured by improper or rough handling. Precautions to keep bearings
clean should be exercised.
Remove bearing cartridge screws before removing end shield screws.
Marking end shields relative to position on frame will make
reassembly easier.
Bearings should not be removed unless they are to be replaced. When
removal is necessary, it is recommended that an authorized Allen-
Bradley Repair Facility be utilized.
The thrust bearing systems used may be one of several types
depending on the application requirements. Your authorized repair
facility is best equipped to service these bearing systems.
Lubrication
This motor has been properly lubricated at the time of manufacture –
it is not necessary to lubricate it at the time of installation. If motor
has been in storage for a period of six months or more, lubricate
before starting.
Lubrication of anti-friction bearings should be done as a part of a
planned maintenance schedule. The recommended lubrication
interval should be used as a guide to establish this schedule.
Cleanliness is important in lubrication. Any grease used to lubricate
anti-friction bearings should be fresh and free from contamination.
Similarly, care should be taken to properly clean the grease inlet area
of the motor to prevent grease contamination.
Recommended Lubricant
For motors operating in ambient temperatures shown below, use the
following lubricants or their equivalent:
* Standard lubricant
Special Applications
Silicone grease may be required in special high temperature
applications. Consult your local Allen-Bradley Representative.
Operating Temperature:
–25 to 50 degrees C (–15 to 120 degrees F) Chevron Oil – SRI No. 2*
Shell Oil Co. – Dolium R
Minimum Starting Temperature
–75 degrees C (–100 degrees F) Shell Oil Co. – Aeroshell #7
!
ATTENTION: Mixing lubricants is not recommended due
to possible incompatibility. If changing lubricant without
motor disassembly is desired, follow lubrication
instructions and repeat lubrication after 100 hours of
service. Care must be taken to look for signs of lubricant
incompatibility, such as extreme “soupiness” visible from
the grease relief area. Failure to observe this precaution
could result in damage to or destruction of the equipment.
