Stainless Steel Wear Ring Removal

Tip of the day: Stainless Steel Wear Ring Removal

This method was sent to me by a friend of mine. Hope it helps someone in the future.

First step is to find yourself a piece of 2 1/4 " aluminum pipe with a 1/4" wall at least 12" long. A longer piece would work better for the extended rings, but its not that important. Make sure that the end that will be contacting the pump is smooth and free of any nicks or grind marks.



The pipe will contact the hub of the pump as shown in this photo.





Place the pump in the freezer for several hours. For those worried about rust, there should be plenty of grease there to protect your bearings and the seals are quite capable of handling the temps.

Remove from the freezer and with a heat gun or touch evenly heat up the pump housing around the outside where the wear ring is located. You don't have to get it scalding hot but I would recommend gloves, since you will have to handle the pump after this.



Once its nice and hot, turn over the pump holding it by the vanes and with your other hand place the pipe inside and line it up with the hub. Now, holding the pump and pipe with both hands, making sure the pipe is lined up with the hub, strike the tube on a hard surface, the top of your vise, cement floor etc. ****NOTE***** you are not striking the tube with the pipe, but moving the pump and pipe as one part, there should be no space at all between the pipe and the hub, this is critical to avoid damage to the hub. This method will create sufficient force to break the wear ring loose.







It should only take a knock or two to jar it loose and then a couple more to get it out.
