1. A maintenance manager is developing a preventive maintenance
management program for a mixed fleet of production equipment that
includes pumps, electric motors, compressors, conveyors, and
hydraulic systems. The organization has historically relied on
corrective maintenance and now wants to reduce unplanned
downtime without performing unnecessary maintenance. Which
principle should form the foundation of the preventive maintenance
program?
A. Replace every component at the same fixed interval regardless of
operating conditions
B. Perform maintenance only after equipment fails so labor is not
spent unnecessarily
, C. Establish maintenance tasks and intervals based on equipment
function, failure modes, operating conditions, and consequences of
failure
D. Increase the frequency of all inspections until equipment failures
are eliminated completely
Answer: C. Establish maintenance tasks and intervals based on equipment
function, failure modes, operating conditions, and consequences of failure
Rationale: An effective preventive maintenance program is based on
understanding how assets operate, how they can fail, and what the
consequences of those failures are. Maintenance intervals should be
justified by reliability information, manufacturer recommendations,
operating conditions, and organizational risk rather than arbitrary
schedules.
2. A facility has experienced repeated failures of a critical centrifugal
pump. Maintenance records show that the pump is being lubricated
every 500 operating hours, but vibration readings indicate progressive
bearing deterioration between scheduled services. Production
management wants to continue using the existing interval because it
appears efficient on paper. What is the most appropriate management
response?
A. Ignore the vibration information because the lubrication interval
was specified by the maintenance department
, B. Review the preventive maintenance interval using condition data,
failure history, and operating conditions
C. Eliminate preventive maintenance because the pump is still
operating
D. Increase the lubrication quantity during every service without
investigating the failure mechanism
Answer: B. Review the preventive maintenance interval using condition
data, failure history, and operating conditions
Rationale: Preventive maintenance intervals should be periodically
validated against actual equipment performance. Condition-monitoring
information can reveal developing failures that a calendar- or operating-
hour-based schedule may not adequately control, allowing the
organization to optimize the task and interval.
3. A maintenance planner is creating a preventive maintenance task for
an electric motor driving a critical conveyor. The motor manufacturer
recommends periodic bearing inspection, while the organization also
has historical evidence of overheating caused by blocked ventilation
openings. Which approach provides the strongest preventive
maintenance instruction?
A. Inspect only the bearings because the manufacturer did not
specifically mention ventilation
B. Clean ventilation openings and inspect bearing condition according
, to documented intervals supported by equipment history and
manufacturer guidance
C. Replace the motor every year regardless of condition
D. Wait for thermal alarms before inspecting the ventilation system
Answer: B. Clean ventilation openings and inspect bearing condition
according to documented intervals supported by equipment history and
manufacturer guidance
Rationale: A sound preventive maintenance program combines
manufacturer recommendations with site-specific failure history. If blocked
ventilation has contributed to overheating, ventilation inspection and
cleaning are legitimate preventive tasks that should be incorporated into
the maintenance strategy.
4. A maintenance department wants to measure whether its preventive
maintenance program is improving equipment reliability. The manager
proposes tracking only the total number of preventive maintenance
work orders completed each month. Why is this metric insufficient as
the primary measure of program effectiveness?
A. Preventive maintenance work orders cannot be measured
quantitatively
B. Work-order completion does not directly demonstrate whether
failures, downtime, or asset risk are being reduced
C. Preventive maintenance should never be documented in a
