• Remove welsh plugs. Drill a small hole off center in welsh plug. Hole should be smaller than plug
removal spear on the end of slide hammer. Using a slide hammer fitted with a welsh plug removal
spear to remove the welsh plug. Be careful not to score the inside diameter of the spindle bore.
• If you do not have a slide hammer you may be able to remove the welsh plug by using a chisel
and hitting the welsh plug off center. This should cause the plug to start turning inside the spindle
unless there is a shoulder behind the welsh plug. Once the plug has turned enough to grab it with
a pair of pliers and pull until plug comes out.
• If plug cannot be removed, drill a 1/2” hole in the welsh plug. Make sure as you are drilling the
hole you don’t score the inside diameter of the spindle bore.
• Insert a long steel rod into the 1/2" hole until it hits the back side of the welsh plug in the opposite
spindle. Steel rod must be longer than the length of the axle. Use a hammer to hit the rod and
knock the welsh plug out. Pull rod out and repeat procedure on the plug with hole with the 1/2"
hole in it. Repeat procedure for second axle. See Figure 2
