These are some notes I made when disassembling an FD 100mm 1:2.8 SSC (80XXX serial number range) some time ago: Unscrew name ring, unscrew the chrome retaining ring found underneath it, remove filter thread ring. Remove 3 screws, remove focusing ring and unscrew outer retaining ring. Then the entire lens assembly comes out. My notes also say that up to this point you don't have messed up infinity focus.
Back when disassembling this one I had to get access to the diaphragm unit and that is only possible from the front. Even if starting from the front would get you access to the rear lens, in your case it may be easier to start from the rear: I have got another copy here (44XXX serial number range) and I can see it has a slotted retaining ring around the rear element. Since removing the lens mount assembly usually is as easy as removing the three screws under the breech lock ring I would try this way first.
Either way you will have to pay attention to properly aligning the diaphragm levers when reassembling the lens. |
