Minolta 70-210 f/4 "Beercan" front cell disassembly

The front cell of this lens needs to be disassembled for cleaning of the elements of the front group.
The front element can be replaced with the identical element from the Minolta MD f/4 70-210.

So the tiny spring shot across the room as I pulled it out and it's gone forever. I reassembled it without the spring, and as far as I can tell it's fine. It looks like it's maybe a ground? Do you know what it's for?

Can you tell how to make fron cell dissasembly of MD version ?

Pete,

Can you make any recommendations for the type of lubricant to use on the helicoid element or should this remain dry? I recently picked up a beercan for a modest price and the focus is a bit squeaky and not very smooth. I'd like to clean it and add some lubrication before putting it through its paces.

Thanks,

Nick

Yes, I do have some spare parts for many AF Minolta lenses.
Sent you an e-mail Nikola

Pete, would you happen to have any spare front element retaining rings for the 70-210 "Beer Can" that I can get? If not, is there anywhere that I can get one for a reasonable price?

Regards,
Nikola Konsulov
