5/8 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 1/8 in. (3.18 mm) set screw
located in the swivel body with the 1/16 in. (1.59
mm) Allen wrench provided and back it off 2-3
turns.

3. Unscrew and remove the remnant stud of the bro-
ken tension bolt.

4. Unscrew the stationary body where it joins the
housing and remove the head of the broken ten­sion bolt and the four bearings.

5. Place the four bearings on a new tension bolt of
the desired tension value.

6. Place the new tension bolt with bearings 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).

Do not apply torque to the head of the ten-

!

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

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

8. 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,
because 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.
