Here’s a YouTube video on rebuilding a water pump from a tractor. At 08:27 there is a discussion about the bearing retainer clip. The geometry of the clips will vary from one manufacture to another, but the concept and function is the same . . . it keeps the bearing from moving. The vane to housing dimension is a key characteristic in pump performance, and let’s not forget the mayhem that would result if the bearing/hub/pulley/fan moved forward.

If the retainer hole is essentially tangent to the outer diameter of the bearing, then wire is used as a retainer.
