Stages on the Path to Equipment Breakdown
• Stage 1: Latent minor defects
Though difficult to see or hear, the machine’s rotating and moving parts are operating under
increasing friction and its fastened parts are getting a little looser. These and other subtle
defects characterize the first stage of equipment deterioration
• Stage 2: Apparent minor defects
The same defects described in the first stage have now become somewhat noticeable to the
eye or ear. In addition, the machine may be vibrating more, making more noise, and leaking
small amounts of oil, water, or air. But none of these defects are major enough to impair the
machine’s functioning.
• Stage 3: Performs below expectations
At this stage, it has become difficult to get the machine to perform with the desired precision
and within the specified tolerances. The machine is turning out products with varying quality
or not performing as specified, and suddenly it needs more adjusting than it use to require. It
can no longer keep up with quality standards and is producing lower yields or performance
expectations.
• Stage 4: Stops Intermittently
At this stage, the machine has to be shut off fairly often to make adjustments to bring the
functioning and product quality back into line. The machine frequently turns out sub par
results, but can be usually started up again after making simple adjustments and repairs.
• Stage 5: Stops or Breaks Down
At this final stage, the machine functions so poorly that it stops itself, which is to say it
breaks down.
We should keep in mind that machines usually break down due to deterioration, and these
kinds of breakdowns never happen all the sudden; they happen in stages. One or more
machine’s deteriorating parts are left to deteriorate and eventually this deterioration
accumulates or combines in a simple or complicated way to cause a breakdown.
If we respond to deterioration only when it reaches the fifth stage, we will have to deal with
various machines that are currently at the other four stages in the path. In other words, we
cannot hope for a true reduction in breakdowns until we work our way up the path and treat
deterioration before it results in breakdowns.
