red Devil SP3 Needle Wheels

[reefmaster70]

I have a large red devil skimmer that uses two SP3 needle wheel pumps. I need to replace both needle wheels as the outer covering on the magnets are cracked open. Could anyone provide a website where I could pick up a couple? Thanks much.

nevemind..I just found some on Ebay...so Ordered a couple of them.

ok, I got the new replacement impellers, but they fit tight, and won't spin once I reassemble the pumps....any help would be great.

where are they tight? in the paddle area or the magnet area?

So looks like I need to shave down the new needle wheels..they are larger (diameter) than the old ones. Any ideas best way to shave down the outside edge to match old ones?

Magnets and shafts fit perfectly, the actual needle wheel itself is larger diameter. And it's direct replacement for SP3 pump

oo thats a toughy.
Maybe a hot knife (xacto style) along the first ring of dots?
