Help me disassembly Yashica 35CC lens for cleaning

[dunghn28]

Just getting this body wth haze glass from the front lens group.
Opening my front glass piece is no problem after I removed the first retain ring. But I can't do anything more when I want to disassembly the next piece of glass which in front of diaphragm because no more retain ring . I also don't found any thread at this piiece of glass.So I am stuck here.

Viewing from the back through back door opened ,I saw the retain ring of the rear lens group. Is it to access the remain glass at the front i have to open the rear len group first ? i haven't tried because my spanner too shallow to reach it.
I am looking forward to getting your advice for next steps. Many thanks for your kind of attention.

You might have more luck posting this on the Classic Camera Repair Forum, where you have a better chance of running into someone who has actually done this repair. http://www.kyphoto.com/cgi-bin/forum/discus.cgi
