I've re-capped 8-10 of the mechanisms (Matsushita JU-570) and while they've all showed sign of leakage, none were as bad as needing to repair the tracks. Disassembly and reassembly looks more daunting than it is, but it's really not so bad. There's no alignment issues, just take the screws out carefully, and in the right order, and handle it gently. IIRC, the cable is soldered direct to the motor PC, so it make it much easier to remove this to work on the board. A couple of years ago I did record a video of me doing it, but never got round to editing and uploading it. If there's the interest, I'll finish it off and upload it to youtube.
