Working with aperture blade Canon FD 50mm 1:1.4 (New version)

In this video I will show you have to disassemble the aperture system and get into the aperture blades, just if there was oil in the aperture system.
In my lens there was NO oil so this I just a tutorial, showing how it works, and what to cleaning with. And I cleaning with Isopropylalcohol 99% ONLY!
NOTE: DON'T even think about the use of Acetone, BECAUSE it will damage the plastic part's.
