Default Should there be any Play in the Water Pump Drive Shaft?

While replacing the water pump drive shaft seal (Twice I still think the seal did not go on right... both times there was a ring of the seal that just came off when it was pressed on. You could still see the seal inside but this was just hanging out and pretty much off... Anyway)
I noticed the shaft had major play in it. I could wiggle it around etc but with the seal in there is no play at all.... is this normal?

Also who has done this seal before, I was told it had to be done dry but frankly I bought another seal as I expect this one too leak to... I just do not see how it could have gone on wrong twice... I know I was careful and lined it up tapped it on but it did the same thing again.

I am really concerned on this as I don't think there should be any but I have very little experience with this setup. Can anyone who has experience with the timing and water pump shaft tell me what they have found?

Both seals in the front of the timing cover can be a pain if you dont have a lot of seal installation experience.

It is normal to have a little play in the pump drive shaft. The pump will hold the shaft straight as long as the spilens are perfectly lined up insied the timing cover and the pump.

Use a little oil, a lip seal installer and patience when installing the fron seals if they are giving you trouble. The lip seal tool looks like a thin piece of wire looped on a small stick or the other style looks kind of like a feeler gauge.

Worst case find a buddy that has done seals to his nature before so you can ensure a proper seal with no leaks!

So far no leaks and I feel a little better now. Trying to get all the air bubbles out but so far so good.

I've done a few, and it's always been a PITA. I've never had any play at all in any of them, in fact it was so tight, we made our own installation tool, by grinding and flaring a pice of pipe.
edit- the green circle was for another post....

They are a PITA. I have mad similar tools/installation pieces for these seal as did "RoAdRaGe912". Your best bet would be to find someone that has done these "LT" style timing covers in your area!

I hate to say it but I am paying to have it done... I did not want too but it has to be done.
