How to remove Vaughn handle?

For Diverter Handle on Escutcheon Plate:

1. The diverter handle is secured to the escutcheon plate with a C-clip. To remove it, you will need to remove the volume control handle, the handle trim ring and the escutcheon plate from the shower valve first.
2. Once removed, use two small, flat-bladed screwdrivers to aid in the removal of the C-clip.
3. On the back of the escutcheon, use one screwdriver blade at one end of the C-clip to keep it from turning and use the other screwdriver blade to push the C-clip end down and out of the groove.
4. With the C-clip removed, be careful to retain the rubber O-ring and metal washer which were under the C-clip.
5. Remove the diverter handle and retain the small black plastic washer which is found on the handle.

1. Remove the plug and loosen the set screw (part #5) by unscrewing it counter-clockwise with a hex wrench (2.5 mm or 1/8").
2. Gently pull the handle assembly (part #1) out to reveal the handle extension sleeve (part #2).
3. Unscrew the handle extension sleeve (part #2) counter-clockwise to remove it from the handle adapter assembly (part #3).
4. Use an adjustable wrench to grab onto the flat on each side of the handle adapter assembly (part #3) and unscrew it counter-clockwise to remove it.
5. Remove the escutcheon plate (part #4) to reach the rough-in valve.
