98 Spx wear ring easily slides out of housing and spins inside

[DaddyLoafin]

It’s a 98 Spx and the old wear ring just came out of the pump housing with little effort with the impeller still installed. The new one goes in the same way and it is soposidly OEM. And there is a gap between the ring and the housing at the bottom. It spins inside the housing.

Does this mean I need to get a new pump housing?
Or is this wear ring not OEM? it came in a box that had Seadoo and BRP stickers and Seadoo part number
Or is this where I would have to put set screws in the pump?

Not sure what you mean by a "gap" at the bottom of the housing, there should not be any gap.

The OD of wear ring doesn’t touch the ID of the jet pump housing on the bottom side. And I can stick my hands inside the pump and just pull the west ring out and im able to spin it inside the pump housing. If that makes any sense.
I’ll take a picture tomorrow with a feller gauge in between the wear ring and housing tomorrow so you can see it better.

It’s almost like the pump house warped into an oval. I’m willing to bet it’s about 0.040 between the OD of the wearing to the ID of the pump housing.

Something is wrong, you should not be able to put "any" gauge in there period.,,,yes, please send pics.

 

[DaddyLoafin]

Will do. If your looking for a laugh here’s the bellow I pulled out of the pressure regulator today.

Here’s pictures of the wear ring that was in it. The engine alignment was way off and one side is worn more than the other and the outside of it looks like it was rotating inside the housing.

Here are the pictures of the gap. It’s about 0.030

This is very unusual, if the alignment is off, the "knurlled" splines in the prop, on the drive s.haft,,or in the pto absorb that,,,Is the gap of the prop in the ring even,,,no more than a mm?

 

[DaddyLoafin]

I got the alignment as close as I could using the home made alignment tool but the splines in the pto were more worn the the splines in the impeller.

I don’t have the ski at my house so I’ll have to bring it back on Tuesday. But, It’s a brand new wear ring in it right now and when you spin the impeller it catches on one side, not sure if that’s normal. But it doesn’t look concentric to the impeller, which I’m not sure if that’s just a worn impeller.
I can spin the wear ring inside the pump clockwise with my hands.

That’s not even close to being normal. Unfortunately I would suggest a new pump.

As previously indicated, the wear ring should not be able to be removed by hand NOR spin/move inside the pump housing......how many stories have I read where some guys need an act of god (or demolition tools) to get the wear ring OUT of the pump housing (or resorting to the freezing the pump trick to get the wear ring to fall out).

The impeller to the pump/wear ring should be concentric with a uniform 1 mm gap between the impeller blades and the ring (per spec).

I was cleaning silicon off the through hull fittings on the pump when I noticed the gap at the bottom and it kinda just pulled out. I figured I’d ask here before I called Westside and spent 200-300 dollars on a good used one.

Judging by all the “quality” works man ship I’ve seen on this so far, I’m extremely paranoid about how the top end was done and what condition the crank actually is in.
