How to replace the tailpiece ring on the backside of a Saffire LX lock

Question

How do I replace the tailpiece ring on the backside of a Saffire LX-D, LX-I.

Answer - Steps to install the replacement retaining rings.

Flip the lock over and upside down to allow thumbs to reach the hub easily.

Remove the existing ring that is loose.

Temporarily slide the gray wire retaining clip out of the way.

Lay the new ring on the hub with the split pointing toward the top of the lock (12 o’clock when normally mounted).

Press the ring down onto the hub using your thumbs.

• You will likely press one side down and then the other (pic 5)
• It will slide down and into the groove (pic 6)
• Make sure the entire ring is in the groove

Snap the new tailpiece in place

• Hold the tailpiece at 45 45-degree angle and slide one side in place, and then rock it straight to lock the other side in (pics 7 & 8)

Slide the gray wire retaining clip back into place with the wire below it (pic 9)

Additional Information
