THE PROBLEM: Over a period of time, generator slip rings become tarnished, oxidized and coated with dirt and
carbon. This contamination build-up results in poor contact between the brushes and the slip rings. The voltage regulator
attempts to maintain a constant output voltage by supplying enough field (rotor) current to support the load. When
the field circuit resistance is high due to dirty slip rings, the regulator must supply a higher voltage in order to obtain the
same field current. This causes the regulator to work harder, run hotter and possibly fail prematurely. In addition, the
increased resistance causes the slip rings to run hotter than normal, further aggravating the tarnish and oxidation problem.
The answer is to keep the slip rings clean. Up until now, this could be a labor-intensive task, often requiring at
least the removal of the brush(s) and brush holder(s) to gain access to the slip rings.
THE SOLUTION: The Slick Stick service tool is designed to clean
and re-finish generator slip rings quickly and safely with the generator
running and without any disassembly. The Slick Stick, made of
durable and insulating acrylic plastic, is thin enough so that it can be
passed through the cooling slots on the rear of the generator. (See
photo @ Left) Then, one of the two precision aluminum oxide stones
on the end of the tool is gently brought into contact with each of the
slip rings. The coarse stone is used for cleaning and re-surfacing severely
contaminated or worn rings. The fine stone is used for polishing
the surface to a smooth finish. Both long-lasting stones are easily
cleaned with detergent and water. The Slick Stick is 14 inches long
and has a non-slip vinyl handle.
The Slick Stick saves time and money by getting the job done
faster. This valuable service can be performed in just a couple of
minutes and can go a long way to help prevent premature regulator
failure. No generator service tool kit should be without one.
