Pics and information by a board member, many thanks, you know who you are!
I had a faulty water pump shaft. Instead of trying to source a new shaft, I decided to repair this one.
Worn out water pump shaft:
Shaft diameter originally 8 mm worn down to 7.5 mm. I machined it further to 7 mm:
I made a tight fit for a piece of 10 mm SS over the 7 mm axle and took the Stainless down to 9 mm:
The oil seal behind the waterseal is a strange size, an almost unobtainable inner diameter of 13.6 mm. While working on the damaged tip, I also machined the mating surface of the shaft down to 13 mm. Now a standard seal can be used:
Because the bearing in the cover was slightly worn, I enlarged it to 9 mm in order to receive the "bigger" shaft (now 9mm with its Stainless sleeve). This should hold up for many years:
