in two axis 65 mm (2.5 in) from top of cylinder
liner bore The cylinder liner grade is marked on
outside diameter of liner.
CAUTION: Cylinder liners with excessively
glazed, worn, scratched or scored bores
must be replaced. DO NOT attempt to hone
or remove glazing from bore. Ensure that if
original liners are to be refitted, reference
marks made during dismantling are not
erased.
