It's okay for the crank to turn slightly when you are dealing with the crank pulley/bolt. Get it loose and then return the engine to TDC. You just need to know that it's at TDC of #1 when you begin the work behind the balancer.
Pull a few of the plugs, be sure that the #1 cylinder is on the compression stroke(TDC). With the engine coming to TDC(turning clockwise)(If you are at the mark on the balancer, back it up 30-45 dgrees, then...), place your finger over the #1 plug hole while reaching the TDC mark.
If you feel no air pressure pushing your finger off/out, then the engine is not at TDC, it needs to go around one revolution. It takes two revolutions to complete one firing cycle, only one of those times where the TDC mark is lined up, is really TDC. The other is on the exhaust stroke, the valves are open then.
Take your time with removal of the balancer, you have to partly install the crank bolt to have something to push on. You have to loosen the tool each time the crank comes out to meet the bolt, and loosen the bolt slightly more. Start with the bolt halfway in, in the next step you can bring the crank bolt out so that it is only a couple of threads on the crank.
You may need to remove the power steering pump pulley first, the bolts are there behind it. Take care with the power steering lines, if it is possible, do not remove or loosen the lines. The teflon seals are not available from Ford, or most places. Good luck,
