Frank,

I truly wish that the answer to that question was yes, the pulley comes off easily, but that is not the case. The bolt that retains the pulley on the end of the crankshaft is in front, in center of the pulley. 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.
