[Mg-t] MG TD failed water pump shaft

[William Putnam]

Thanks to everyone who responded to my query.  I have yet to hear of any other Phil Marino water pump shafts failing.
   
   I've asked Phil to make a new shaft with no keyway-the taper should be sufficient to transmit the torque required to drive the impeller.  I also plan to run a 7 blade plastic MGB fan in place of the original.  With these two changes, I hope to reduce the potential for future failures substantially.
  
 Again, thanks to all who responded.
