As "Dolce Vita" indicated, two important factors in maintaining "Swageless" mechanical terminals are:
Sealing against moisture
Not preventing air from passivating the stainless
No special tools are required to install Mechanical Swageless Terminals. Slip the body of the terminal over the diameter of the cable. Unlay the outer wires, and fit the cone over the centre core
. Re-lay the outer wires onto the head
of the fitting. Draw the body up to the head
, and screw together. Mechanical Terminals can be re-used, but a new cone must be installed each time.
SWAGELESS TERMINAL INSTALLATION
INSTRUCTIONS (Norseman, Sta-Lok, etc)
1. Measure and cut the wire rope
If using a hacksaw, tape the ends of the wire rope at the mark, and cut rope through tape.
2. Unscrew the end fitting from the body and remove the cone.
Slide the body over the wire rope.
3. Un-lay (unravel) the outer wires from the center strand.
A screwdriver is useful for this.
4. Fit the cone over the center strand with the long taper facing the body.
5. Position the cone on the center strand with 1-1/2 times the rope diameter protrusion. Reform the outer wires around the cone, one at a time.
Ensure that the cone remains in its correct position.
6. Push the blind hole in the fitting over the end of the cable.
Bring the body up the wire rope and hand screw the two pieces together.
If using a left hand lay rope then turn only the end fitting.
If the rope is a right hand lay then turn only the terminal body.
7. Once the two pieces have been screwed together 2 or 3 turns, the terminal can be completely wrench-tightened by turning the end fitting.
DO NOT OVER-TIGHTEN, this will not improve the performance of the fitting and may result in damage to the screw threads.
The fitting is sufficiently tight when the cone is fully seated in the taper inside the body. Until this occurs there will be minimal resistance to turning the end fitting.
As soon as the resistance increases the fitting is tight enough and should not be tightened further.
8. Unscrew the end fitting and inspect the internal assembly.
Check to make sure that none of the outer wires have gotten stuck in one of the slots in the cone.
The outer wires should be evenly spaced around the cone.
9. Apply a non-corrosive marine sealant
to the blind hole in the end fitting and to the inside of the body.
Screw up the assembly hand tight.
Repeat if necessary until sealant
oozes from the body and wipe away excess sealant.
10. Apply the threaded locking adhesive
to the screw threads and re-tighten the terminal, per step 7 above.
