6-10 LUBRICATION
All parts that require lubrication have been lubricated
during the assembly with molybdenum disulphide grease
(Cutler-Hammer Material No. 5370 1QB). Over a period of
time, this lubricant may be pushed out of the way or
degrade. Proper lubrication at regular intervals is essential
for maintaining the reliable performance of the
mechanism. Every 12 to 18 months or every 2000
operations, whichever comes first, the circuit breaker
should be relubricated. The locations shown in Figure
6-1
should be lubricated with a drop of light machine oil.
After lubrication, operate the circuit breaker several
times manually and electrically.
Roller bearings are used on the pole shaft, the cam shaft,
the main link and the motor eccentric. These bearings are
packed at the factory with a top grade slow oxidizing
grease which normally should be effective for many years.
They should not be disturbed unless there is definite
evidence of sluggishness, dirt or parts are dismantled for
some reason.

If it becomes necessary to disassemble the mechanism,
the bearings and related parts should be thoroughly
cleaned. Remove old grease in a good grease solvent.
Do not use carbon tetrachloride. They should then be
washed in light machine oil until the cleaner is removed.
After the oil has been drawn off, the bearings should be
packed with Cutler-Hammer Grease 53701QB or
equivalent.
