Hello,
My IBM 35-7 stopped running because it had no power to the escape wheel. Since the movement has been recently lubed, I suspected the cable drum.
I locked the drum, removed the weights, removed the electrical peripherals from the movement and then removed the movement. After unlocking the drum, I tugged on the weight cables and noted a "tight" spot. The tight spot disappeared and then the cables pulled down easily.
I had previously (last week) put some oil in the hole at the screw at 2 o'clock on the front iron bracket. It looks like an oil hole. Today, I dropped some oil on some of the gears in front of the actual cable drum. Everything has been re-assembled and is now running fine.
I see three screws in the iron bracket on the front of the drum assembly. If I want to service the cable drum, what happens when I remove those three screws? No doubt, there are bearings in there. Does anyone know what to do to dis-assemble the drum?
Jim
