SECTION 1: MAINTENANCE STRATEGIES
Questions 1–10
1. Which maintenance objective most directly supports the purpose of an effective
lubrication program?
A) Preventing lubricant-related failure before it causes secondary machine damage
B) Eliminating every planned maintenance activity
C) Increasing the number of lubricant products kept in inventory
D) Replacing condition monitoring with fixed calendar intervals
Correct Answer: Preventing lubricant-related failure before it causes secondary machine
damage
Rationale: Effective lubrication is intended to control friction, wear, contamination,
temperature, and related degradation so machinery remains reliable. Preventing lubricant-
related failure reduces the likelihood of secondary component damage and unplanned
downtime. Lubrication therefore supports reliability rather than simply serving as a routine
maintenance task performed independently of machine condition.
2. A plant experiences repeated bearing failures even though technicians lubricate
bearings according to a calendar schedule. What should be investigated first?
A) Whether the bearings are painted correctly
B) Whether lubricant selection, quantity, application, and contamination control are
appropriate
C) Whether all bearings can be replaced with larger bearings
D) Whether lubrication should be eliminated
,Correct Answer: Whether lubricant selection, quantity, application, and contamination
control are appropriate
Rationale: A calendar interval does not guarantee that the correct lubricant reaches the
bearing in the correct quantity and condition. Bearing failures can result from overgreasing,
undergreasing, contamination, incompatible grease, or incorrect viscosity. A systematic
review of lubrication practices is therefore more useful than simply increasing the frequency
of lubrication.
3. Why can poor maintenance have a significant effect on plant profitability?
A) Lubricants always represent the largest operating expense
B) Maintenance affects only spare-parts consumption
C) Failures can create downtime, repair costs, production losses, and safety consequences
D) Preventive maintenance eliminates all production costs
Correct Answer: Failures can create downtime, repair costs, production losses, and safety
consequences
Rationale: Machinery failure has consequences beyond the cost of the failed component.
Unplanned downtime can interrupt production, require emergency labor, consume spare
parts, and potentially create safety or environmental problems. Effective maintenance
reduces these consequences by controlling failure mechanisms and improving equipment
availability and reliability.
4. What is the principal purpose of a well-designed lubrication route?
A) To maximize the amount of lubricant applied during each visit
B) To ensure lubrication tasks are performed consistently and systematically
C) To eliminate equipment identification requirements
D) To allow technicians to choose lubrication points randomly
Correct Answer: To ensure lubrication tasks are performed consistently and systematically
Rationale: A lubrication route organizes equipment, lubrication points, procedures,
frequencies, and observations into a repeatable process. Consistency makes missed points
less likely and improves the quality of lubrication work. A good route also provides
opportunities to identify abnormal conditions before they develop into significant machinery
problems.
5. Which practice best improves the reliability of equipment identification within a
lubrication program?
A) Assigning unique, consistent equipment and lubrication-point identifiers
,B) Using informal names that differ between technicians
C) Removing tags after the first lubrication
D) Identifying equipment only by lubricant brand
Correct Answer: Assigning unique, consistent equipment and lubrication-point identifiers
Rationale: Unique identification links the physical machine to its lubrication instructions,
lubricant specification, route, sampling location, and maintenance history. Consistent
identification reduces the possibility of applying the wrong lubricant or servicing the wrong
point. It also improves communication among technicians and makes lubrication records
more useful.
6. How does oil analysis contribute to a maintenance strategy?
A) It guarantees that equipment will never fail
B) It provides information about lubricant condition, contamination, and machine-related
changes
C) It replaces every other maintenance technology
D) It determines production output directly
Correct Answer: It provides information about lubricant condition, contamination, and
machine-related changes
Rationale: Oil analysis can provide evidence concerning lubricant degradation,
contamination, and wear-related changes. The information can support condition-based
decisions when interpreted with equipment history and operating context. It does not
guarantee failure prevention or replace all other inspection and condition-monitoring
techniques.
7. A lubrication route repeatedly contains missed points. Which corrective action is most
appropriate?
A) Increase the amount of lubricant used at the remaining points
B) Remove lubrication documentation
C) Review route organization, point identification, scheduling, and technician execution
D) Replace every lubricant with a synthetic product
Correct Answer: Review route organization, point identification, scheduling, and
technician execution
Rationale: Repeated missed lubrication points indicate a process problem rather than simply
a lubricant problem. The route should be examined for accessibility, identification, workload,
, frequency, instructions, and accountability. Correcting the process makes reliable execution
more likely and prevents the same omissions from recurring.
8. Which statement best describes the role of lubrication in failure avoidance?
A) Lubrication affects only machine appearance
B) Lubrication can reduce friction and wear while helping control heat and contamination
C) Lubrication makes mechanical alignment unnecessary
D) Lubrication eliminates the need for inspection
Correct Answer: Lubrication can reduce friction and wear while helping control heat and
contamination
Rationale: Proper lubrication establishes an appropriate lubricating film, reduces damaging
contact, and can help dissipate heat and exclude or transport contaminants. It does not
correct alignment problems or eliminate inspection requirements. Lubrication is one
important element of a broader machinery reliability program.
9. What is the strongest reason to use condition information when establishing lubrication
practices?
A) It can help determine whether current intervals and lubricant practices are producing the
desired machine condition
B) It makes lubricant specifications unnecessary
C) It ensures every machine receives the same interval
D) It prevents the need for equipment histories
Correct Answer: It can help determine whether current intervals and lubricant practices
are producing the desired machine condition
Rationale: Machinery operating conditions vary, so identical calendar intervals do not
necessarily provide identical results. Condition information can reveal whether lubricant
degradation, contamination, or wear is occurring. Using that evidence allows lubrication
practices to be adjusted more intelligently instead of relying solely on arbitrary fixed
intervals.
10. A technician discovers two nearly identical machines with different lubricant
requirements. What should control the lubrication decision?
A) The lubricant with the lowest purchase price
B) The lubricant most commonly used elsewhere in the plant
C) The equipment's documented lubricant specification and operating requirements
