Repairing a Mamiya TLR 55mm C lens. At least in the U.S., these lenses mounted in a Seiko SLV shutter are not common. This shutter had several issues: sticking slow speeds escapement, stuck diaphragm and shutter blades due to heavy oil contamination and a damaged shutter blade. The oil on the blades makes a complete disassembly necessary to clean the oil from the blades and surrounding mechanism. It’s time consuming and you have to go slowly. If you rush, it is guaranteed that something will not go back together properly. I have to be in a calm mood when I take these apart.
