The FT-1 can be partially disassembled fairly easily, but I caution there are many delicate parts inside and it's not something I'd recommend.
With that said, you need to remove both the shutter speed dial and the rewind knob/ASA dial. The shutter speed dial is removed by unscrewing the little pin faced screw in the middle. There are special tools for this, or something can be made to do the job. Once that's off, the rest of the assembly lifts off. Observe the parts and their positions as you take them off, to be able to reassemble it all properly and most easily later.
Next, look at the rewind knob. With the camera back open, use something to prevent the fork that fits into the top of the film cassette from turning, and gently turn the knob counter-clockwise. It will unscrew. Under it you will find three or four more screws that hold the ASA dial in place. One is longer than the rest, again note all the parts and their positions.
I seem to recall there might be one wire to unsolder before you can fully remove the top cover, be very careful around the folded printed circuit boards inside the top cover! It's quite complex under there and I personally always leave this type of work to a professional camera technician, although I am pretty handy at many other things!
