There is an original tool for flyside seal that you screw onto the taper; Not being reproduced and rare.
Most people will not have this tool. What I recommend is to take a small screwdriver and push the seal a little to get over the berm of the seal surface of the crankshaft.

Same goes for the clutchside. Begin to pull the crankshaft into the case. Back the puller off and make sure the seal is over the berm; use a small screwdriver to push the lip of the seal.

I use transparency film as a guide over the crank's lip. Cheap and easy...
