Corrosion in impeller housing UNDER wear ring??

[mateospeed]

Folks, my driveline was locked last time I tried to go ride, killing my day on the water and making me very sad. boohooo ok now that's over.

i found my impeller was locked in its housing. Upon disassembly, I noticed bubbling of the wear ring. I filed it down to obtain proper clearance, until I could get a new part in. I found some serious corrosion BETWEEN the aluminum impeller housing and the stainless wear ring itself. Is this common? Has anyone ever seen this before? I don't know how water would get in there to allow that surface to corrode!

Thanks!

Unfortunately it is very common.

The Solas 100% stainless wear ring is a heavy and expensive option but it won't suffer the same fate.

well, crap. I'm surprised my efforts to search didn't turn much up if it's so common.

Very, very common.

I wrote about it in post #2 here:

Thanks. After modifying my search wording, I found that post. I can't tell if the WSM and/or SBT wear rings are complete replacements, or just OEM parts with different liners pressed in? I believe my OEM housing is in decent shape, and would be useable with the corrosion cleaned up, if I could re-use it after a clean-up pass on the lathe. That is, if I can press in a plastic liner.

Has anyone else done this? I very seriously doubt if either manufacturer would release dimensional data on their liners to figure it out myself.

You need to replace entire housing.

Well dang, if you're so quick to reply to the tread, I'll just ask publicly instead of PMing: why? My interest is piqued.

Once the corrosion starts, it just keeps going.

The SBT wear ring is a nice part for the money. It's a new casting, not reman OEM

Under the plastic liner I grease it up

If you think splitting a wear ring housing sucks, imagine how it feels when it happens on a Skat Mag pump...
