Step 8: This step offers cable routing and installation procedures.
Make sure that cables move freely in their cable housings before
installation.

Installation recommendations:

• 4 inch (102mm) minimum allowable cable housing bend radius
• Use plastic wire ties/clamps to attach cable housing to
structure after installation and adjustment
• Do not compress cable housing
• Recheck to ensure cables move freely
Step 9: This step describes how to first attach the drive (short) end of
a cable to its interlock assembly and cable bracket. See Figures 8 to
11 for details:
1. Remove small nut, compression spring, and spacer tube from end
of rod.
2. Slide rubber boot toward tip of rod.
3. Unthread outer bulkhead nut and slide nut and lock washer toward
tip.
4. Insert threaded end of rod into swivel fitting.
5. Slide smaller diameter portion of bulkhead fitting into cable bracket
slot (see Figure 10).
6. Raise cable assembly until threaded portion of bulkhead fitting
enters slotted hole in cable bracket (threads show above bracket).
7 . Bring bulkhead washer and nut down to threads and hand tighten.
8. Adjust two bulkhead nuts to approximately center the bulkhead
fitting on the cable mounting bracket.
9. Hand tighten the bulkhead nuts at this time.
10. Slide rubber boot back into place over end of bulkhead fitting.
11. Replace spacer tube, compression spring, and small nut on end of
rod.
12. Lower nuts should be shouldered against end of thread and upper
nut tightened against spacer tube.
