    Default Wear Ring Removal and Installation

    Ok guys I am questioning myself. I heated up the insulator ring and as it was melting i removed the brass wear ring. The insulator looks ok I think. My new wear ring will not go in. Do I need to heat it up again and slide it in? I have a pic I will post in just a few

    Put the new wear ring in your freezer to chill (shrink) before intalling with a new liner

    Not sure on the picture sequence ?? when you say it wont fit do you mean in the suction with the old W/R and liner out (not yet removed completly?)

    looking at this further it looks like it has the remains of an older Dominator wear ring left in the suction which need to be removed prior to progressing further it also looks like it has lost a thrust bearing ? and caused some unrelated gouging to the suction (which may not be a problem) Step 1 carefully carve out the remains of the old style Dominator wear ring (blue plastic) Tom

    FWIW when the "intructions" out there on the net say to heat the wear ring to remove it , they don't apply to this style Dominator , it simply prys out ..

    Tom is great help, thank you so much!
    Just to keep everyone in the loop, the blue liner is a plastic crap that the brass wear ring was in and per a pump manual I heated it up to melt it so I could get the wear ring out, I was under the impression that my new wear ring would press right in, however it just seems too iffy for me to do last night, without some experienced help.

    looks to me like you have a dominator style wear ring and the remains of the liner is still there, remove debris down to clean aluminum and follow toms directions.

    Tom, the suction does not have the tag on top of the bearing housing, see in the back ground of this picClick image for larger version.

    the pic tells the tale, it is a dominator, remove all of the blue and clean area. your new wear ring will most likely have a wear ring liner that goes in first to retain it.

    First thing- throw the new wear ring in the freezer like Tom said( I left mine over night just because). Now clean out the rest of the old liner from the seating area, once the wear ring has been chilled for a few hours you can now press it in. It should press in by hand slightly and then you will have to use a mallet and a block of wood to seat it the rest of the way. Double check your wear ring once installed with a caliper so that it is square in the bore, I believe it should not be over .004" between any location you check.

    This issue still lies in the Vintage on that suction, It will be usefull to try to get a precision measurement of the Suction to determine the exact bore as there are (i suspect) there may be couple possibilities , also curious to see what Impeller and for that matter they sold you (Berk style or Dominator ) a shot of the back the back of the impeller will tell Tom

    yada,yada, yada, i know its hard to repair them with such little eyes and big hands, i know that assume is the mother of all f--k ups, but hey i trying. but while im at it and this is not a definitive answer, BUT, MOST of the dominators i have seen the blue liner was the standard late model bore like berkely and at, the green thin one was the old odd ball size. this does not mean that you should not measure the bore correctly as the wear rings MAY have been in an assortment of colors that i did not see.
