Impeller Replace / Upgrade - New Wear Ring Cut-Up

[Joester]

My second post to the site and thanks in advance for any help. Here's the skinny...

I have an 06 RXP with 78 hours. Dropped it at the shop to have a new, complete carbon kit, impeller upgrade to 14/19 and new wear ring. I had already removed the nozzle and pump. They charged me 3 hours labor....which I didn't think was right..

Now, they only installed part of the carbon kit and the new wear ring they installed is being cut up by the new impeller... Can you tell me if this wear ring issue is a screw up or is this normal??? Again, I appreciate all the input.

Bet the alignment was off. Why'd you up the prop?

It sounds like a screw up to me I always thought you were supposed to check the clearance between wear ring and impeller brand new it's supposed to have .005 clearance it says in service manual to check with feeler Gage or shim stock. After you install . It doesn't sound like they did it to me .

The prop was in bad shape and the shop told me I would get a little more speed (1-2 mph) and better hole shot. Was this the wrong thing to do?

Guess I need to find another shop to install a new wear ring...

Or do it yourself at least you will know it was done right

Well...a 14/19 could use a bit more air to turn at the same rpm for more speed so...not a wrong thing...just an....incomplete thing. Put a 4" front air on instead of the oem air intake and you should do fine...might have to tweek it.

A prop will cut into a new ring...just a bit. That's why a new ring should be installed with a new prop....'cause the new prop won't be exactly like the old. Oem rings are inexpensive.

Rings aren't difficult to install. Look up the "freezer method".

Oops, my bad red2blue... I have removed the OEM air box and installed the 4" front air when I bought the ski new from the dealer.

I will try to do all the work myself next round. Then I know its been done correctly...

Thanks again for all the input!

What's the best site to buy parts for the RXP / RXT?

Measure the clearance between impeller and ring, should be near or better than spec around the perimeter. A new ring needs to be tight as possible to impeller and normally (often) the impeller will rub and clearance around the new ring. If the clearance gap is too large somewhere around the diameter the pump will lose some efficiency accordingly, tighter is better which explains why it's necessary to have some initial rubbing to establish a tight clearance.

I don't know about yours, but my 2001 GTX had a spring loaded piece in the jet pump cone that was mistakenly left out when they replaced wear ring. This piece keeps the drive line under pressure back to engine where carbon ring is. Without it, the moment I started it, the impeller chewed up the inside of jet pump vanes.

WOW, apparently they didn't water test your ski either and yes, the cone spring is important to keep the drive line loaded. Maybe they didn't even start the engine....
