Thanks.  I'd found no mention of this in the LUG archives.

Right now I have just a little fore-and-aft looseness in the filter ring.
But where there is play, there is likely to be accelerated wear, leading
to further looseness, etc.

Does anyone know what causes the looseness to develop initially?
