Hi,
The front crankshaft pulleys are usually tight, a puller is used to remove them.
There is originally no bolt used to hold the pulley on, just the tight fit.
The pulley can be worn where the seal runs on it, that is the reason for the sleeve in the listing above.
TM Tractor has just the seal also, if you don't need the sleeve.

The front end of the Cub has to be removed to remove the pulley, maybe you knew already.
The Cub service manual has info about removing the front.
Below is the Cub service manual, if you don't have it.
There is a table of contents beginning on page 1 of most sections, it makes it easier to use online.
The info for removing the front is in section 1, the Engine section, on page 1-10, and the 1st paragraph on page 1-11.
In paragraph 2 on page 1-10 it says remove the headlights, that is for square front Cubs, evidently.
If you have a Cub before the square front Cubs, you don't remove the headlights, they are mounted to the hood.

I would wedge the front axle before removing the front, then the upper part won't tip over to the left side.
You will need to make 2 wooden wedges, and hammer them in tight at the axle pivot.
Be sure they don't hit at the small end, they have to be tight on the top and bottom of them.
Below is a pic of wedges.

It helps pullers work a little better to oil the long threads with motor oil. Work the oil through the part that the long rod threads into also.
Dry puller threads can have friction when pulling hard on pulleys and other parts. :)

A d when you get ready to put the new pully on, the manual says to NOT tighten down the front cover bolts until the pully is installed, to allow the seal to center on the pully shaft.

And here is a HOW TO for easy installation of that pully:
