Gents,
ALL the 216 water pumps that I have seen had the pulley SPOT Welded to the flange in 4 spots.
Its NOT rebuildable from that side,
You have to take it apart from the Backside after the plate comes off the back.
Leest thats what an oletimer told me, an the first thing back on the shaft is the new seal,etc etc etc....
Regards,
