Shaft Play...
« on: March 14, 2009, 01:03:21 PM »
This is a real jet pump question Omar  >:D

How much, if any, should there be?  I removed the bowl, and when I grab the impeller shaft it has  "up and down" play.  Maybe 1/4".

A Berkeley has no preload on the mian bearing so the bowl bearings take up the "slop, I don't think there is a spec for bearing end play, but at 1/4" I would be a little leary of the impeller to wear ring clearance (unless of course the impeller is removed  ;) )

My thoughts exactly, there shouldnt be anywhere that much play with the impellor in the wear ring.

OK, I need to figure out how to remove the impellor so I can check it.

If you need to get it together right away, lemme know, still got an assembled pump ready to roll.. ;)

Looks to me like you will find more Gremlins about...bowl problems and whatnot...

I "feel" that it could be fixed, however, I dont know how deep the scratches can go so I really dont know.  I am guessing a clean up and a new wear ring and it would be fine.  Throw on an new impeller and some bearings and it would be good to go.  I am replacing it so if anyone needs parts... ;)
