Barings in a variable speed pully

I just got a white outdoor lt 1500.I dropped the deck to check the blades. When I put the deck back on and tried to drive it it died and I lost all tension in drive peddle. The smaller belt was sucked up under the larger belt on the variable speed pulley. when I got it out I noticed the pulley has a lot of play in it. I pulled the pulley and there is no ball barings in it is this normal? Part number 956-0048
