Which post-repair acceptance test is MOST appropriate to verify alignment quality after corrective coupling replacement on a pump-motor set?
Answer: Precision alignment verification using a laser alignment system or dial indicators with reverse-dial method
Laser alignment or reverse-dial indicator methods provide quantified angular and parallel misalignment readings that must meet OEM tolerances before return to service.
A corrective maintenance technician identifies a failed component as a 'wear-out failure.' This means the failure is best addressed long-term by:
Answer: Implementing a preventive or predictive maintenance task timed to the component's wear-out interval
Wear-out failures follow a predictable aging pattern and are best prevented by scheduling replacements or inspections before the end of the component's useful life.
When a corrective maintenance task requires confined space entry to repair internal equipment, which document MUST be completed before entry?
Answer: A permit-required confined space entry permit with atmospheric testing and rescue plan
OSHA 29 CFR 1910.146 mandates a permit, atmospheric testing, ventilation, and a rescue plan before entry into any permit-required confined space.
After completing corrective maintenance on a plant air compressor, the technician observes the unloading pressure is 10 PSI lower than the pre-failure setting. The CORRECT action is to:
Answer: Adjust the pressure switch or regulator to restore the OEM-specified unloading pressure setpoint
Returning the compressor to its specified pressure setpoints ensures downstream equipment receives adequate supply pressure and the compressor operates within design parameters.
The 'return to service' checklist for corrective maintenance should include which item to protect instrumentation from damage at startup?
Answer: Verify that all instrumentation isolation valves are opened and transmitters are re-ranged to operating conditions
Instrument isolation valves must be re-opened so that pressure readings are live, safety interlocks are functional, and gauges show actual operating conditions.
A corrective maintenance history report shows the same bearing location failing every 3 to 4 months. According to reliability principles, this pattern indicates:
Answer: A chronic or repeat failure with an unresolved root cause requiring investigation
Repeat failures at a consistent interval signal that corrective maintenance is only addressing the symptom, not the root cause, and an engineering investigation is needed.
Which corrective maintenance practice BEST supports continuous improvement in overall equipment effectiveness (OEE)?
Answer: Capturing detailed failure data, performing root cause analysis, and implementing corrective actions to prevent recurrence
OEE improves when corrective maintenance data feeds root cause analysis that drives permanent corrective actions, reducing failure frequency and unplanned downtime.
