CYLINDER LINER
CHECKING WEAR OF CYLINDER LINER
1.
Set a cylinder gauge and adjust it
to
the reference valve of the cylinder liner with
an
outside
micrometer.
2.
To
find out the maximum
wear,
measure the diameters
at
six points
on
the cylinder liner with
the
cylinder gauge,
as
shown
below.
NOTE:
When the cylinder liner is worn beyond the allowable limit, bore and hone it by 0.5
mm
(0.0197 in.).
1.
The cylinder liner which has been oversized by 0.5
mm
(0.0197 in.) should use a piston and
ring of the same oversize.
NOTE: When the oversized cylinder liner is worn beyond the allowable limit, replace the cylinder
liner, and bore and hone
it.
See engine specifications.
