Chrome-plated cylinder liners are
being used in increasing amounts both by original equipment manufacturers, and
by aftermarket sources.
It is recommended that chrome-plated rings not be installed
in chrome-plated liners under any circumstances. Catastrophic destruction will
likely result. Plain cast iron-manganese phosphate coated, or molybdenum rings
may be used. It is normally difficult to detect visually in a used cylinder if
it is chrome-plated or not.
If any doubt exists, a solution of copper sulfate (CuSO4), which can be
purchased at any drugstore or chemical supply house, should be applied with a
cotton swab to an area of the liner. If the liner is not plated, a copper color
will appear. If it is chrome plated, no change will take place. Never use
chrome in chrome.
Cylinders are normally chrome plated for two reasons — to
increase service life or to re-furbish worn liners.
