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.

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.

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.
