Step 13 - Evaluate the CloSure
comparing the test tape with the illustrations in Figure 6-
18. If the marking is similar to 6-18A, measure the over
travel
"x": If "x" is greater than or equal to 0.6 inches, the circuit
breaker performance is satisfactory. If "x" is less than
0.6 inches or if the marking is similar to 6-18B or 6-18C,
immediately contact the Product Integrity Center for
Technical Support at (412) 787-6518.
Step 14 - Remove the CloSure
front cover onto the circuit breaker. Return the circuit
breaker to its original configuration and setup.

6-10 LUBRICATION

All parts that require lubrication have been lubricated
during the assembly with molybdenum disulphide grease
(Eaton Material No. 53701 QB). 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.
Once a year or every 500 operations whichever comes
first, the circuit breaker should be

relubricated. The locations shown in Figure 6-1 should be
lubricated with a drop of mineral 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 Eaton
Grease 53701QB or equivalent.
