How important are essential craft skills and precision maintenance?

Maintainability Center (RMC)

Because of his extensive applied
experience in improving
machinery/plant performance, I asked
Tim Dunton, Director of Product
Development, Reliability Solutions,
Walnut Hill, FL (reliabilitysolutions.
net), a UT-RMC training partner, to
discuss why learning essential craft
skills and using them to perform
precision maintenance is
so important. Here is his
answer to this month's
question.
In the past few
decades, much has
changed in the world of
asset reliability. Obviously,
the tools and technologies available today offer
unprecedented ability to
monitor and measure the
performance of our equipment in significant detail.
These technologies can,
if used properly, provide
deep insights into how
and why things fail, thus
providing an opportunity
to prevent or control those
failures. Remember, it's
not the data that is important. It's how we utilize
the data that counts. It's
easy to get wrapped up

in the mountains of information the
technology provides and lose sight of the
real goal.
If we truly want to improve asset
reliability and performance, we have to
change our approach. Most important,
we must recognize that reliability is
everyone's responsibility. While this
article focuses on maintenance activities,
without the involvement of everyone
in your organization, results will be
mediocre at best. In many maintenance
organizations today, emphasis is often
placed on changing parts as quickly
and efficiently as possible. If you want
to improve machine performance and
reliability, you must assemble and install
parts such that they extend machine life.
Precision maintenance is an
approach that aims to place the machine
in an improved or precise state. It is
executed with discipline, precision, and
control, and audited for reliability. As
part of a broader reliability process, the
proper assembly and installation of
machinery is where an immediate
impact can be realized.
The techniques required are not complex or technically difficult and include
activities such as eliminating unbalance,
misalignment, and assembly errors. Simple errors such as incorrect key length,
excessive run-out, improper tightening
of fasteners, and soft foot, individually
can shorten machine life, but collectively
can contribute significantly to reliability
problems.
Documented results indicate that

Precision maintenance aims to place an asset in an improved or precise
state through a disciplined process that emphasizes proper assembly and
installation.
