7.
Liner projection must be 0.059 to 0.199 mm
(.0023 to .0078 in.). Make the measurement to
the outer flange of the liner, not the inner ring.
The maximum difference between high and low
measurements made at four places around each
liner is 0.05 mm (.002 in.).
NOTE: If liner projection changes from point to point
around the liner, turn the liner to a new position within the
bore. If still not within specifications, move liner to a
different bore.
NOTE: When liner projection is correct, put a temporary
