Konica AR Hexanon 135mm 3.2

[FD101]

Are any of you guys familiar with disassembly of Konica telephoto lenses?? I have done some repair work on the 50mm 1.7, they are pretty good lenses. Here is the problem.

The focusing collar won't go to the infinity mark, it stops about 1mm short. Looking thru the viewfinder at an object at infinity isn't in focus.

The lens appears to be in original condition but it wouldn't have left the factory (back in 1973!!) in that state so I guess a previous "repairer" has incorrectly adjusted the focus.

So how to get at the helicoid and make the adjustment?? Any ideas.

PS If anyone has questions about the Autoreflex T, T2, and T3, I may be able to help.

Unfortunately no much knowledge here about this lens, sorry.
