There can be no failures going forward. If one single error is allowed to creep in, it could very well signal the beginning of the end from a range of angles and/or factors. In the universe of mechanical engineering, mechanical engineers go to bed at night with that word precision etched deep into their foreheads. A typical day in the life of a steadfast mechanical engineer could be the addressing of numerous mechanical engineering failures caused in different capacities across the town.
Part of the mechanical engineer’s daily mechanical or engineering life is the routine rigmarole of diagnostics. This precedes everything else. It turns out that it is a good time saver as well. The diagnostics equipment that mechanical engineers now have at their disposal allows for them to root out engineering or mechanical failures within a matter of hours. To expect a maintenance inspector to do so within minutes would of course have been utterly unrealistic.
Remember, precision is the watchword over here and if it takes that long to get the engine right then so be it. But it most certainly will not take days or weeks to fix. All good and well to have your own diagnostics testing equipment to hand. You know where to make the insertions or pegs. But do you really know why these pinions are where they are? And do you really understand the readings that you are picking up?
Thought so. So of course, unless you are a fully qualified electrical or mechanical engineer yourself, go do yourself a favor and let the professionals do the testing work for you. You might as well since they might have to attend to the repairs and/or replacements or installations as well.
