LUBRICATION STRATEGIES

to code on an initial repair, making it
preferable to only code the Symptom
and Effect on work-order completion.
If it has been analyzed for, the Cause
code can be added prior to closing the
work order in the system.
Lubrication, when performed
correctly, results in the successful separation of moving or bearing surfaces
to reduce friction, heat, and wear.
When lubrication is lacking, bearing
surfaces will deteriorate rapidly and
show distinctive symptoms that can
be coded as "excessive heat," "excessive vibration," "excessive noise."
Interestingly, these symptoms also
present themselves when a properly
lubricated driver/driven system
has been misaligned on setup. This
illustrates the need for more than one
code set, preferably three (Symptom,
Cause, and Effect) to understand and
trend the fault/failure and all different
root causes. When the symptoms,
causes, and effects are trended and
analyzed with regard to such things as
equipment and system types, OEMs,
failed parts, suppliers, and contractors, specific and systemic problem
causes can be quickly pinpointed and
corrected.

Words of warning
There are literally thousands of
codes that can be used across the
three recommended-code sets.
Consequently, it can be very tempting,
when setting up the code database, to
populate the search filter with as many
codes as possible. This approach can
lead to duplicated code sets across
numerous search filters.
As discussed, for codes to be
meaningful, they must reflect the
types of symptoms, causes, and effects
specific to a plant. Too many codes
are onerous to manage, and personnel
will quickly lose interest in ensuring
the most appropriate ones are used.
That situation, in turn, will lead to
low-quality or untrustworthy data. A
good way to prevent it is to conduct a
trial run.
Prior to entering and using code

MAINTENANCE TECHNOLOGY

Don't waste valuable
data space by using
'other' and 'N/A'
catch-all codes.
data in your asset-management
software, set up test-code sets in
spreadsheet software. Then take a
representative set of old work-order
copies and practice-code them to see
if the results are valid, useable, and
reflective of your operations.
Keep in mind that once a code is
in use, it's very difficult to retire, as
it is linked to work records that can't
be erased. During set-up, the choice
of codes should be a judicious one,
recognizing, at first, only the known
typical symptoms and failures found
within your plant. Never squander
valuable data space using "other" or
"N/A" catch-all codes.
Remember, too, that code
complexity is dependant on the culture

and training of personnel expected
to recognize and input codes on
work orders or in asset-management
software. In my experience, organizations that have the greatest success in
leveraging fault/failure codes to help
manage their reliability programs
typically use between 10 and 20 codes
for each search filter. (Some of them
have also worked as long as two years
to fully develop their coding systems.)
Since ineffective lubrication
practices are responsible for as much
as 70% of all mechanical failures,
lubrication codes are used primarily
(and most effectively) in relation
to mechanical-related failures. This
means sites using these codes must
take into account other failure types,
including, for example, electrical.
Those failure will also need to be
coded-and require code space. MT
