Cleaning Shutter blades in MAMIYA-SEKOR 50mm 1:4.5 RB67 motion lapse film

Cleaning Shutter blades in MAMIYA-SEKOR 50mm 1:4.5 for the RB67. There was A LOT oil in this shutter, but with some gently use of Lighter Fluid and a lot's Q-tip, it turn out to be very good and with the snappy sound from the shutter. I only have problems when i would show how you come further in to the shutter, because one screw was gluet. The front lens group has a focus adjustement, so take care when disassemble, there is a LITTLE BALL in the edge, and also remember to do some mark's before disassemble.
