3.) Install the crankshaft assembly by positioning the crank-
pin anywhere between the unlocked and connected
positions as shown and lowering the crankshaft to the
bottom of the slot. During crankshaft assembly installa-
tion 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
4.) Rotate the bar caps downward
5.) Install the bar cap pins through the bar caps and left and
right mechanism assemblies with the head of the pins
toward the center of the breaker.
6.) Install an E-ring on each bar cap pin.
7.) Complete steps 1 to 4 on pages 23-26 to verify the lock
bar is in the proper position . It should be necessary to
pull the interlock lever down before racking the drawout
and the lever should return to the engaged position when
the drawout reaches the unlocked test, or connected
position If the interlock lever does not operate in this
manner the lock bar is not in the proper position and step
3 above must be repeated. Failure to ensure proper
drawout operation may result in the drawout not locking
in the proper position with possible injury to personnel
and damage to equipment.
