Note:
It is not possible to rehone the liner because of the
conical shape. We always suggest to exchange the
cylinder together with the piston and rings.

Note
: The excessive clearances or gaps are because of
the abnormal wears of the cylinder liner, piston, and
rings. We always suggest to exchange the cylinder
together with the piston and rings.
