Internal Accessories

Preparation For Installation of Internal Accessories

3. Install the crankshaft assembly by positioning the crank pin any-

where between the unlocked and connected positions as shown

and lowering the crankshaft to the bottom of the slot. During crank-

shaft assembly installation, the lock bar must be held in the proper

position. This may be done by inserting a screwdriver into the

double-D hole (if present) and pushing until a solid stop is felt. If the

double-D hole is not present, use the rectangular cutout to gain

access to the lockbar as shown.

4. Rotate the bar caps downward.

5. Install the bar cap pins through the bar caps and left and right mech-

anism assemblies with the head of the pins toward the center of the

breaker.

Note: Bar cap pin should be reinstalled on the side it was originally

removed.

6. Install an E-ring on each bar cap pin.

Note: e-ring should be installed on the side of the plate that it

was orginally removed.

7. Complete steps 1 to 4 on Unlocked Position to Test Position on page

22 to verify the lock bar is in the proper position. You should have to

pull the interlock lever down before racking the drawout, and the le-

ver should return to the engaged position when the drawout reach-

es the unlocked, test, or connected positions. If the interlock lever

does not operate in this manner, the lock bar is not in the proper po-

sition and step 3 above must be repeated.

Perform steps 1-5 on test position to unlocked position on page 25,

returning crankshaft to correct position before breaker installation.

NOTE: Failure to ensure proper drawout operation can

cause the drawout to not lock in the correct position.

Injury to personnel and damage to equipment can result.
