RMC Tokina 28-85mm focussing ring

[King Regula]

I have just bought an Minolta srt101 at a yard sell and it came with two lens a MC Rokkor 55mm and RMC Tokina 28-85mm for 10 bucks. What I like to know is has any one had any experince on disassembling and RMC Tokina 28-85mm as the focussing ring just ceeps trunning only time it will focus is if I hold the ring hard. Looking at the lens I am thinking it maybe some loosen set screws for the focussing ring. Tho I cant see any why to get at the set screws from the front unles there under the name ring. Do I just lift and pull out the name ring some how or do I get to the set screws from the back of the lens?
I would appreciate comments for instuction/repair information that any one can give

Thank you

This is a rangefinder forum, you know... Your story sounds like a fixing screw (one of those tiny ones maybe, under the rubber grips?) is loose or missing.

Don't know the Tokina lenses myself.

Had taken the name ring off at the front and one the set screws where loose. works good now.
