Overhaul
Installation and Service Manual
Place a heavy steel plate of the correct size, against the
end of the wear ring (the plate prevents damage to the
end of the wear ring and should cover the whole
diameter).
Using a large hammer, drive the wear ring evenly into the
impeller race
Continue driving the wear ring into the impeller race until
the wear ring sits flush with the inner recess of the
impeller race.
The wear ring must not contact any part of the jet unit
except for the insulating strip.
After fitting, check the electrical insulation between the
wear ring and the impeller race. The resistance should be
greater than 1000Ohms
