Heres some pic of my impeller. What do you think?
Looks as if it got pulled against the wear ring and the wear ring dug in.

The bushings the shaft rides on in the tail of the bowl from the looks of that thing they are gone.An imp can only be turned down so much befor it becomes to thin in that area.I would say you might be looking at anew imp.Send it to a pro pump shop and have them mic it.
Jake eek!

Depending on the size it has wore down to, you probably can machine it down and get an undersized wear ring. How's the front bearing. It looks like maybe the whole shaft/impeller assembly was shoved foward into the housing, causing the raised edge you pictured. A bad front bearing could allow that.

Yes , It can be machined of in the lathe ,Or just take a file to the raised "Burr"
Maybe the person that set up the pump Did not set the correct Clearance between the wear wring and the impeller ,Or the wear wring could have backed out a little.
I would look at the bearing & maybe the suction housing, For wear.
Keep us posted!
Also what size O.D. is that machined flat surface on the impeller.

Well i dont think the pump was ever rebuilt. I am completely taking the jet apart and buying the rebuil kit with everthing except the impeller (maybe the complete kit with impeller now :) ) What happened was the thrust bearing went, but i dont know haw long it was bad. when i took the bowl off no oil came out for the bowl bearing either. I havent gottin the shaft out yet. I need to get the motor out Sunday (maybe).

Clown, If i think i know what you are telling me to measure, the impeller is a "A".

The Dia. where the wear wring sit's is what I'M talkin about look for 7.225" Dia.

If your Thrust Bearing went South...(like alot)...think about the force that was now put on your Crank shaft. Now this also depends on how much clearance there was between your Impeller shaft and drive line yoke. I have about an 1/8-3/16" in mine.
Was this a stock Berk...without the shouldered Wear Ring?
Do your self a favor...just buy both matched parts WearRing+Impeller...and a NEW thrust Bearing...and NEW Bowl Bushings. Don't half step the job.

Well i got the shaft out and i see that the thrust bearing is a 1/8 off of the snap ring. Now it wasnt that hard to get out so i dont think that the bearing moved on the shaft when it hit it with a block of wood and a lite hammer. Is it posable this is why my impeller looks the way it does?? That someone didnt pless the bearing on enough?
Here is a pic of the shaft were the bowl bearing sits. The shaft looks fine to me. No excesive wear in that area. The bowl bushings looked alright. Are they steel? I am still going to replace those. It was hard to get a pic of the bushings.

Clown, The measurment came out to 7 3/16.

Clown, The measurment came out to 7 3/16. Bowl Bushings are a rolled alloy inside coated with teflon for wear. The rolled section has a split for compression fit in the bowl. No oil in the bowl means the seal was gone. Make sure you get a Lipped Wear Ring when you get
your kit. Good Luck.

make sure the shaft is straight.

As you will see by the pic, that the bearing mushed around the spacer. The spacer is good and the shaft is true :) . What causes that?

My friend who pressed the bearing off said it was realy stuck on there. Could all this lead to why my impeller is why it is?
