I have repaired this problem several times on Minolta X-7A (X-370) and X-700. Over time lubrication dries up, friction goes up, it gets harder to crank the advance lever. Finally the friction is so great that one of the gears in the advance gear train reacts to the overload, caused by excessive friction, by shifting out of place and leaning hard on the other gears, not allowing them to freewheel back to their reset positions. The bad news is you must disassemble the camera and thoroughly clean and lubricate it, as well as putting the shifted gear back into position. This takes me about 8 hours to do and I have done it about 6 times before. Very labor intensive and you must be a very good technician. |
