Appendix B: Transmitter Wire Repair or
Replacement
The cable lead and other end cap components in the cable transmitter must be replaced
when the wire shows wear, twists, or abrasions. This involves removing the transmitter end
cap to access the cable lead connection to the transmitter base. The Replaceable Wire Kit
(DCKIT) includes enough parts to replace the cable lead two times. You will also need a
standard screw driver.
The DCKIT contains:
Two cable leads
Four Torx screws
Four lock washers
Four 2-021 O-rings
Two screw insulators
Two 2-106 O-rings
Two brass set screws
Three white nylon set screws
One T15 Torx wrench
One each

installed, remove the two Torx or buttonhead cap screws and lock washers.
3. Pull the end cap from the transmitter base.
4. Identify the deepest set screw depression in the base. Using the

that holds the cable lead to the base.
7. Remove the old wire, the 2-106 O-ring, and the screw insulator. Removing the old
wire from the base may require some force.
8. Install a new insulator and 2-106 O-ring onto a new cable lead, and insert the wire in
the base. Ensure only
5
