Case IH 8450 or Hesston 550 baler question

I just acquired a 8450 round baler which is the same as a Hesston 550. I got the belts relaced and in the process noticed something with the guides on the front lower belt roller (see photo). There's 2 guides on this roller. One of them is welded to the roller. The second spins free and there's no evidence of any welds. I'm wondering if this is the correct setup or was the welding an owner modification.
