Water pump bearing removal & shaft repair
The first picture shows the removal of the sir sir clip that retains the bearing, this is the one hidden by the distributor shaft drive cog. The second picture shows the parts once they have been separated there are a couple more bearings not in this picture the one that is the bearing for the bottom of the distributor shaft drive I haven't got any pictures but it is easy to get out and there are two washes on the bottom side to help with spacing, the third picture shows the socket I used to press the bearing out it was a 1" sidchrome socket 1/2 inch drive with two extension attached, the socket was 33.49mm external diameter it needs to be that size so that it presses on the outside edge of the bearing without interfering with the aluminum housing. The Fourth picture shows the water pump in the press ready to pres the belt drive cog end bearing out.
The last picture shows the shaft once I had got all the parts off as you can see the shaft was very pitted, if the seal re seats on the good section indicated by the green arrow then I could probably get away with it as is but if the seal mounts where the red arrow indicates then it is unlikely it would seal so I have sent the shaft off to an engineering shop to have it repaired, they said they would either weld more metal onto the shaft and then machine it back down or they would manufacture a sleeve for it, will show you the results when it gets back.
