Well, Roland and I actually agree on this one.
He said what I was going to.... but I will add that the ball bearings will have more play than the needle bearing will.
To the OP:
For the record, you aren't being very clear. That is why I am misunderstanding. Makes no sense to me why you would measure shaft deflection
after remove the charge pump (which includes the support bearing) so I naturally assumed (because I'm a mechanic) that you measured it
before removing the pump.
Just put a new bearing and seal in and I'm sure you will be fine. More than likely the old bearing was fine, but it's not like it was an expensive part.
