The forward portion has four slots and what sort look like teeth and that's where you engaged your hand crank, assuming that is what you used to turn the crankshaft. The center of it is hex shaped (1 3/8" across the flats) which is where one tightens or loosens the screw.
Assuming that you're able to loosen that screw then the pulley is pulled forward to remove it or in you case enough to create some clearance to remove the front motor mount bracket. The problem is that the pulley, if original, is made of cast iron and it is very easy to chip the lips of the pulley if you simply try to pry at the pulley to move it forward. The only safe way to pull the pulley forward is with an appropriately-configured puller, preferably one with at least three fingers to capture the back lip of the pulley in three places. Depending on the size and configuration of the puller there may not be enough room between the front spring u-bolts/hand crank guide/raised portion of the front cross member to permit the puller to be square with the crankshaft pulley.
There's about 3/4" of clearance between the front of the pulley and the back of the raised portion of the front cross member which is more than enough room for your purpose of moving the pulley forward an 1/8th or so.
May be you will be very lucky and can slide the pulley forward once you have removed the retaining bolt. In addition to the pulley being a relatively tight fit on the end of the crankshaft, the oil seals in the bottom of the timing gear cover and the top of the front of the oil pan will fight you as they understandably are a tight fit up against the shank of the pulley. You've loosened the front timing gear cover so that will take the pressure off that side of the oil seal. You would need to drop the front end of the oil pan to relieve the pressure on the oil pan side of the oil seal. It still very likely will not be enough for you to be able pull the pulley forward without the use of a puller of some sort.
The front end of '33-'34 four-cylinder engine is the epitome of dumb design.

I remember reading that the model B engine was longer than the v8 so they had to make modifications. I never know that that meant disposable engines!
Funny, I have another model B engine that I bought from the guy that sold me this car. He said it was rebuilt. From it;s serial number it was built in 1935... And it has no ledges on the timing cover.. I guess they learned their lesson.
May I should cut off the ledges on my 1933 engine then I could slid the bracket right of. The bracket has 2 bolts that go into the Timing cover They probably do not need those 2 PIA ledges..
What would be the best way to cut or grind off those ledges???
I would make sure to drain all the fuel out and let the car duel lines dry out before cutting or grinding the ledges.
