Link rod on the top to
loosen the bottom Quick-
Link connector. Be careful not to
damage the Top-
Link rod. It may help to twist the connector
while pulling it out.
6. The Quick-
Link rod is as long as the bushing conductor. Pull
the rod out of the
bushing from the bottom. It must be pulled
out far enough to allow cleaning of the contact surfaces. You
may pull the rod all the way out, but it is not necessary at this
time.
Do not damage the contact surfaces.
The contact surfaces are on the
outside of the Quick-
Link connector
and the inside of the Quick
socket. These surfaces must remain
clean and smooth to be able to pass
rated current.

Removal Instructions
1. Remove the top terminal and o-ring.
2. Remove the nut on the Top-
Link brass rod under the
terminal.
3. Attach a wire or strong cord
that is longer than the
the rod, using the small hole on top. E
nsure this wire or cord
as fastened can pass through a Ø1.00 hole.
4. Remove the fasteners
holding the bushing to the
transformer.
5. Remove the pin holding the Top-Link to the
center conductor
6. Push the rod
down from the top to disengage the Quick
connector from the socket on the bottom. You may need to
use a rubber mallet
to apply enough force to disengage the
Quick-
Link connector. You may want to place a piece of wood
or plastic over the end of the ro
d to prevent damage.
Be sure to have a good hold on the
wire so the assembly does not
fall into the transformer.
7.
Lift the bushing out of the transformer while holding the wire
to keep the rod and connector assembly from falling into the
transformer.
Do not pull the assembly too hard,
you may damage the internal
transformer connections.
8.
When the bottom of the bushing clears the top of the
transformer tank, you will see the Bottom-
Link rod. Keep
lifting the bushing until you have enough room to
comfortably reach in and grab the rod.
The rod may be
slippery due to the oil of the transformer.
9. The Quick-
Link rod has a joint in the middle. On the standard
designs, this joint is located .75 inch above
the flange
mounting-
surface. The joint is threaded, allowing for
rotational adjustment to align the top pin.
