Yes, you need to remove, maybe loosen the torque bracket to get the belt off. With the belt off check your fan bearings for any problems. I had to replace those bearings on my 882 because they were worn out and also check the idler pulley bearings too.
The bracket is in the 4 o'clock position looking at the front of the tractor as seen here. It keeps the pto from spinning around beacuse they are not bolted to the engine like the other tractors are.

Here is what the fan shaft looks like broke down.

Good luck and keep us posted on how it goes.
