OK, so I've fitted new seals to my water pump. Both seals are perfectly seated and the shaft was pulled through very carefully. Everything turns with just as much stiffness as you would expect.
However, the drive gear is not perfectly flush with the casing all the way round. In some positions it is slightly below, in others slightly proud. If I use a washer in order to pull the shaft in further, the inner face of the gear will touch the pump casing (verified with a feeler gauge).
Obviously the shaft is only seated in the pump end at the moment; once fitted to the engine is it likely to align itself the first time it runs, or will it knock seven bells out of the inner casing?
Just as an aside, where the half moon cut out is on the engine, there is no corresponding hole or channel on the pump side. The pump casing is blank.
