Out transmission has quadrants, not roller bars, and the problem is that the
baton travel for one of the bells (the one with an exceptionally loose
clapper) is often (but not always) reduced dramatically, and the reason
seems to be that the clapper is still well off-centre, having swing there at
the previous stroke, and is thus nearer to the bell and hits it too soon. A
number of the other clappers are loose, although not so much as this one.
Anyway, I've emailed Andrew Higson at Taylor's asking for his advice, but it
does seem likely that we will need to rebush most of the clappers.
