7/8 in. Break-Away Swivel

Disassembly Procedure

The following disassembly operation will deal with
small parts. Disassembly and re-assembly should be
done in an area where parts will not be lost if acci­dentally dropped.

1. Retrieve both halves of the broken swivel.

2. Loosen the #6-32 x 1/4 in. set screw located in the
swivel body with the 1/8 in. Allen wrench provided
and back it off 2-3 turns.

3. Unscrew and remove the remnant stud of the
broken tension bolt.

4. Unscrew the stationary body where it joins the
housing and remove the head of the broken tension
bolt and the five thrust washers.

5. Place the five thrust washers on a new tension bolt
of the desired tension value, making sure to follow
this sequence: steel, plastic, steel, plastic, steel. Now
check to see that every other washer is steel.

6. Replace the O-ring (if missing) where the swivel
body mates with the housing.

7. place the new tension bolt with washers through the
housing and screw the bolt into the swivel body.
IMPORTANT: Do not over tighten the tension bolt,
because premature fracture may occur. Tighten the
bolt lightly until it bottoms (don't use excessive
force) ... then, unscrew 1/2 turn to achieve proper
bearing clearance and swivel action.

Do not apply torque to the head of the

!

tension bolt as over-stressing the bolt may
cause a lower breaking point.

8. Re-tighten the set screw into the side of the swivel
body.

9. Screw the stationary body and housing together and
tighten.

IMPORTANT NOTICE
Users are cautioned to ensure appropriate safeguards
exist especially during aerial cable placing. Should the
swivel break there must be sufficient support to pre­vent the cable from reversing direction and creating
slack in an uncontrolled and potentially hazardous
manner. This is critically important when crossing
rights-of-way such as roadways, waterways or power
lines. Refer to your employer's work practices or con­sult the factory for detailed information pertaining to
this most important safety procedure.
All personnel should stand clear of the pulling line

when using any break -away swivel, in the event that
excessive pulling resistance causes the swivel to break
apart and possibly exit the duct at great speed.

Notes:

1. Breaking tolerance ±5%

2. Warning!! Do not over tighten the tension bolt, be-

cause premature fracture may occur. Tighten the
bolt lightly until it bottoms (not using excessive
force). Then unscrew ½ turn to achieve proper bear­ing clearance and swivel action.

3. See other side for disassembly procedure.
