No problem other than removing the old one, you might find it easier to screw it in than out but it may bottom on the brake band before it falls out inside the housing.
It doesn’t go through anything other than the bottom of the cast iron housing so no alignment problems

Tony, if you can get that old screw out and replace it, then do it, when adjusted properly it carries the weight of the brake band and prevents the top section of brake lining from resting constantly on the brake drum and possibly wearing that section prematurely.

The Owners Book tells us to adjust it by fully tightening it, then undoing it a turn and a half, a show tractor will never wear the brake lining out up on top of the band, but why not do the job right while you are looking at it, it should come out easily in a minute if you can lock 2 nuts on that stub, if not, weld a nut on to it and screw it out, often that housing has oil sitting in it from weeping seals so the old screw should not be rusted solid.

From memory it is a simple 3/8" coarse thread, so a good hard bolt should work there with a locking nut.
