Another variation is to remove the top cover as well as the bottom 
cover, and push the old RFC out from below.

With the two covers removed and the rig upside-down on the bench, first 
use solder wick to remove any surplus solder, then heat each pad and 
push the lead of the RFC through the hole using a sharp probe. The RFC 
drops out onto the bench. This method works equally well with the KRX3 
in place, because the RFC falls clear of the KRX3 housing.

The new RFC can then be soldered underneath the board without needing to 
cut any tracks.
