new wear ring too tight

[pwgsx]

I replaced the wear ring on a 95 gtx by placing it in the freezer. I then installed the new one with the impeller still in the pump with no trouble. Now after the pump warmed up I cannot get it to spin. The starter cannot turn the pump. Any ideas? I don't have a impeller tool to try and take it off.

You put the entire pump in the freezer? To remove the old wear ring? I've put the new rings in the freezer t get them to fit in the pump, but not the opposite. I dint know how you could get the new ring in if it's so tight the impeller won't spin.

Yea the whole pump to remove the old and froze the new ring to install. Somehow after it warmed up now the clearance is too tight. I don't get it.

Warmth expands, it was deff right ring for that model? (silly ? but anythings possible). So if you did grab wrong ring or they messed up and gave you wrong one, once it got warm that baby went back to size and got jammed now. A pic or two wouldn't hurt also

Are you using an OEM wear ring?

Take the cone off and turn it over with a wrench. Downside, you'll need oil.

It was a sbt ring against my better judgment. I'm very puzzled, it deff looks the same. I need to find a larger vice to hold if I try turning it from the inside of the come.

Actually I've got SBT delrin wear rings in two of my ski's and they've been excellent, however I've heard mixed reviews.

Yea I am puzzled on this one, everything went in fine. I went in for lunch, came out and the darn thing was stuck. Well last night I was able to turn the shaft on the pump cone side but the only way it would finally spin was unscrewing it. So now I have a impeller stuck in the wear ring inside the pump. WTF

 

[LouDoo]

Well, I think at this point you're going to need to get an impeller remover tool, remove the impeller and take a look at the bearings and impeller shaft. Honestly I've not heard of this before, but like my Dad always said "the farmers mule never died before either".

So with the pump shaft removed - the short shaft that's under the pump cone, the impeller "should" be free right? Just need the tool to try and spin it out from the grasp of the wear ring......or maybe punch it out from the other side.

I dunno, I think I'd make sure the pump shaft is tight on the impeller and see how difficult the impeller is to turn using the impeller tool. Once the engine begins turning the impeller(assuming it's possible), it's going to gouge out the clearance in the wear ring, and you'll have as tight a clearance as is possible once the custom fit is lapped?

The seadoo manual I have suggests using seadoo lube on the impeller/wear ring to reduce the initial friction until the lapping is complete but I think some light oil or liquid dish soap would work as well.

This is assuming the impeller isn't being held atrociously tight by the wear ring and the engine can actually be started.

Somehow the impeller and ring is tighter than a bulls ass during fly season. The engine would not turn it over or even move it a hair. I ordered the impeller tool, should be here later this week.

 

[Sportster-2001-951C-Stock]

Yep, must be a garbage ring then. I've heard some bulls have incredibly tight ones especially during fly season, and the more wrinkles the tighter they are.

So there is no way you can put the impeller shaft back in and turn that with a wrench enough to cut the new ring ?
How about turning that and using the driveshaft as your tool. Just wrap a strap around the driveshaft and use a bar to help rotate it in the right direction while at the same time turning a wrench on the back side of the pump in the same direction. I'm sure it would only take a turn before it would cut the right grove.

What about freezing the whole mess again and then quickly throw it on the machine and start it up just to cut the groove ?

Just throwing ideas out there.

How tight is it? It's "cochliomyia hominivorax" tight man!

Its a SBT ring :banghead: I got it on ebay and it wasn't what was pictured. Glad I didn't pay much for it .........I tried re-install the short shaft into the pump and then put the long driveshaft in the vice clamp and rotate with a long wrench with a added pipe for leverage but it kept slipping in the vice. I didn't want to mess the shaft up so I stopped. Hoping the impeller tool comes and I can use my long breaker bar OR air impact to get it to spin and cut the groove. Right now the pump is back in the freezer and I plan to try and remove the impeller after work if its loose enough.

Meanwhile maybe if you freeze it you get an idea of it's gonna be a real bear.

 

[LouDoo]

Is this a Delrin wear ring?

[68ragtop]

Any chance this is the style shaft where the thrust washer might have jumped out of place & the thing is mechanically bound up?
Or it it safe to assume the impeller has never been removed?

 

[dustindu4]

Buying the thing off eBay is the first warning sign, is it a sbt knock off? Mine has given me no issues

I suspect someone slipped him a length of schedule 80.

A picture is worth a thousand words.

I'm really not interested in seeing his pipe, LOL!
