wear ring instalations question

[396_WAYS_TO_SPIT]

How do some of you guys install your wear rings? Just curious to see how many different ways there are...

I use a customized impeller for this job.

[sanger rat]

Same here. I have and old impeller with the center milled down so it don't bottom out on the shaft.

[flat broke]

Throw the wear ring in the freezer for 4 or more hours, fit the insulator and trim it, then drive the new wear ring in with the old impeller. The reason you freeze the wear ring, is because believe it or not it will contract. The reason you use an old impeller to drive the ring in, is because the impeller will help keep the wear ring going in square to the housing. Since you're ordering a new wear ring, take some measurements on your impeller and figure out your undersize from there. For a lake deal, .025 total side clearance (half of that per side) would be fine. So take a set of calipers to your impellers wear ring surface, measure the o.d. (assuming tht its straight and clean) and add .025 to the measurement. That will tell you the inside diameter of the wear ring you'll probably end up with. If it's a box stock impeller, just order up a std size.
For a lake use deal that may not see a lot of maintenance, a shouldered wear ring is the safer bet. But all you have to do is look at a pump with a shouldered wear ring vs non shouldered and you can see how the shouldered wear ring'd pump probably gives up some performance in a racing application. Every time water passes over one of those ridges formed from the edge of one part not meeting flush with another, a potential site for cavitation is formed. In non-shouldered setup there is only one gap between the suction housing and the face of the impeller. In a shouldered setup there is a small gap between the suction housing and the shoulder on the wear ring, and a second gap between the wear ring and the impeller. Albiet small gaps, they are areas that alter flow and possibly reduce efficiency.
Hope that helps,
Chris

Step by step sort-of !!!

What is the K&N lube for? A little narration, would be nice with the pictures too.

Damn no audio on this forum.
I use the K&N lube in place of silly cone, easier to work with down the road.

Don't ask, Jim was having a moment with his ... well nevermind ... it might be too personal ...
Sorry Jim ... it was too funny ... had to post it ... j/k ... :D

that was funny sh!t right there:D :D

[sanger rat]

What Jim does is slick. First he fills the gap between the pump and transom with silly cone. Then after it drys he uses the K&N grease the seal the Sanger pump ring to the transom. Makes things much easier to pop the bowl off for impeller changes.

[396_WAYS_TO_SPIT]

Its all about the grease :crossx: :crossx:

396,
I made this to put mine in. After freezing the ring I used this. It kept everything nice and square and it pulled right in tightening the allthread.

I hope everyone is seeing that it is not a good idea to be pounding on a impeller to install there wear ring. Most of these suction housings are old, this alone put the fear of stress cracking to mind.
1) Freeze the wear ring
2) heat the suction housing
3) install insolator
4) install wear ring by hand
5) using some way to press hold the wear ring in place till suction housing is cooled to room temp. I use a custom cut impeller and press hold with the impeller nut.

I am not so sure of how good of an idea is of heating up the insulator with a propane torch this might be why some one will get a spun ware ring.
If you take your time and a block of wood and cold ware ring it works just fine.And the use of a hard rubber type of mallet.

You do not heat the insolator it melts. You heat the suction housing.
The reason most spun wearings happen is they were run dry or they have rocky sand in them.

[Duane HTP]

Or they were set up too tight to start with.

I forgot about that one Duane, I guess I was taking it for granted that it was set up with proper clearances.

[Jake W2]

I see you have done some editing.
