TR4A wobbly water pump pulley

[John Middlesworth <jape@email.unc.edu>]

I noticed some knocking under my TR4A bonnet last night and finally
determined that my (original-style) water pump pulley was loose.  A little
inspection showed that just tightening the nut at the front of the pulley
would not cure the problem.  Given how many of these nuts are stripped out
in these cars I imagine this is a common problem.  Am I looking at
replacing the pump, the pulley, or both?
