I have the following problem. I’m trying to repair my Rolleiflex 2.8e, and adjusting the shutter speeds is very, very stiff, almost impossible. I’ve removed the front cover, and the adjustment dial on the Synchro Compur shutter itself moves smoothly. The adjustment with the gears at the back of the front cover is also relatively smooth. I disassembled all those gears (in the back of the front cover), applied grease between all the surfaces, and reassembled it so that it runs somewhat smoothly. However, when I reattach the front cover, adjusting the shutter speed becomes very stiff again. I can’t figure out why this is happening. Is it correct to grease between the gears, or should everything remain dry there? Do you perhaps have another idea for a solution?
