NH 268 baler pick up sticking

The last couple hay seasons i have been having issues with the pick up sticking on my NH 268 i saw that the two bearings that support the main shaft need replaced. The cam bearing have some play but not much but i will replace them aswell while i am in there. My main question is about the four rods or shafts that the pickup tines are bolted to. There are four rods that go through two hubs , where the rods go through it seems to have alot of play in there . Id say an 1/8 inch on the plunger side and maybe even alittle more on the cam side. There are no bearings or bushing that go in there that incould replace . Any advice here? I am hoping the problem is just the bearings that i am going to replace so i dont have to buy a whole new pickup wheel basically. Any advice would be appreciated !
