Water Pump Impeller

Water Pump Impeller
Has anybody removed a water pump assembly before...? It would not be a normal type of item that would be replaced, but I have a brand new replacement right side engine cover, which does not come with the water pump assembly. I am ordering a new oil seal (for the bearing) and what Honda calls a "Mechanical" seal for the water pump shaft...but the water pump has a ceramic seal that contacts the mechanical seal....which has a line (Crack?) going through it. Is this normal or did the ceramic seal crack when I pressed it out? Take a look at the Pic.

The ceramic seal in your picture with the crack is no good. Use that and it will leak.
Remember when pressing the impeller back in, you have a very small margin for error on installed depth. Get it wrong and the impeller rubs the case or the cover.
