Replacing the Center Conductor Contact
Not all parts on the adapters are replaceable, but all of the
adapters have a replaceable center conductor contact.
When you replace the center conductor contact, observe the
following precautions:
• Before installing the new center conductor contact, apply
Loctite sealant #222 to the threads of the center
conductor.
• Do not use excessive force when tightening center
conductor parts.
Model K281C (All Options)
To replace the center conductor, you will need a 5/64 inch
hexagonal nut driver.
In some units, the center conductor mounting hole was
made oversized to allow for a slight adjustment. When the
center conductor is replaced in these units, it may be
necessary to readjust and retest if the unit does not meet
specifications.
If the mounting hole appears to be oversized, mount the
center conductor toward one end of the adapter as far as it
will go. If the adapter fails the performance test, move the
center conductor toward the opposite end and then retest.
