I tried to take the bezel off my SOHC to reallilgn the insert. Someone had told me they are 'difficult' to remove, it turns out they're impossible!
I assumed that the retaining screws would be ready to drop out and get lost, so my plan was to whip them out, lift off the bezel, remove and clean the insert, move it round 1/2 a minute, superglue it back in place and then put the screws back in with Loctite.
I was foiled from the off! Those little screws were totally solid, absolutly no shifting them without risking damaging the heads or slipping and scratching the case. I believe they're real as all the slots are at slightly different angles, they've just been glued in securely. Some heat would probably shift them, however, it'd wreck everything else...
If anyone knows of another way to get the insert out, please let me know, I tried a razor blade around the edge but it fits too well!
