03 Big Bear 400 crankshaft

I?m trying to get the crankshaft out to have it rebuilt. I have everything off the crankshaft except for the oil pump drive gear and the balancer shaft gear. How do these come off? They are right against each other with the smaller gear to the outside. The gear I would have to put a puller on is the balancer drive gear. I don?t want to mess it up. The service manual doesn?t really show how to do it. I can?t find any videos on it either. Didn?t know if I could just press the crank out and the gears come off as I press it out or what. Thanks for any help.
