Title: Shaft Play...
Post by: The Chaz 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.

Post by: The Chaz on April 21, 2009, 07:06:37 AM: 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... ;)
