7.5.3 Disassembling the wear ring
After removing the Top Pull Out unit the wear ring can be removed. In most cases the
ring has been fixed so tightly that it cannot be removed undamaged.
1 Measure the thickness (d) and the width (b) of the ring, see figure 5 A.
2 Make a centre hole in the middle of the edge of the ring at two opposite points, see
figure 5 B.
3 Use a drill with a diameter just a little bit smaller than the thickness (d) of the ring and
drill two holes in the ring, see figure 5 C. Don't drill deeper than the width (b) of the
ring. Take care not to damage the fitting edge of the pump casing.
4 Use a chisel to cut the remaining part of the ring thickness. Now you can remove the
ring in two parts from the pump casing, see figure 5 D.
5 Clean the pump casing and carefully remove all bore dust and metal splinters.
7.5.4 Assembling the wear ring
1 Clean and degrease the fitting edge of the pump casing where the wear ring is to be
mounted.
2 Degrease the outer edge of the wear ring and put a few drops of Loctite 641 on it.
3 Fit the wear ring in the pump casing. Take care it is not pushed out of
alignment!
