    With an I.D. micrometer or diak caliper for the wear ring and an O.D. mic or caliper for the impeller.

    Just for giggles just to see if it would work I used clay between the wear ring and impeller...and it worked pretty darn good! Almost like claying for valve/piston clearance. I had the clay in three locations, top, bottom, left, right.
    Took a few times to get the feel how I needed to pull the impeller off so not to disturb the clay but yea it worked. I found I had to oil/lube the impeller area and the clay surface first.
    NOTE...keep in mind, my Impeller was zeroed out on my shaft. A Impeller not trued on the running shaft will have some run-out thus, the clearance will be less and greater at some locations as the Impeller turns.

    I did this with my son's playdo to figure out a starting point for the length of my cam's thrust bearing/button

    When I tried Playdough it was a little to spongy...modeling clay held the shape perfectly
