Preparing a new wear ring for fitting

Trial fit the new wear ring into the tailpipe with no insulator fitted.

There should be a gap of 1mm ±0.1 between the mating ends of the wear ring when completely inserted

into the tailpipe bore.
The wear ring may not fit without filing the mating ends slightly to reduce the
circumference.
Do not remove too much metal from the ends of the wear ring.
The wear ring must be a tight fit in the impeller race once the insulator is fitted.
