Maintenance refers to the broad range of activities undertaken to ensure that equipment, machinery, or systems continue to function effectively over their intended lifespan. It encompasses preventive, corrective, predictive, and condition-based maintenance, aiming to prevent failures, fix issues, predict future problems, and respond to the actual condition of equipment.
Types of Maintenance
Preventive Maintenance
Preventive maintenance (PM) is performed regularly on equipment to lessen the likelihood of it failing. It is planned and conducted routinely.
Corrective Maintenance
Corrective maintenance (CM) involves identifying, isolating, and rectifying a fault so that the failed equipment, machine, or system can be restored to its operational condition.
Predictive Maintenance
Predictive maintenance (Pdm) techniques are designed to help determine the condition of in-service equipment and predict when maintenance should be performed.
Condition-Based Maintenance
Condition-based maintenance (CBM) dictates that maintenance should only be done when certain indicators show signs of decreasing performance or upcoming failure.
What Is Servicing?
Servicing specifically refers to the regular upkeep and routine repairs of equipment or systems. It is a subset of maintenance focused on keeping the equipment in good order, typically including tasks such as lubrication, cleaning, minor adjustments, and periodic inspections.
Types of Servicing
Routine Servicing
Routine servicing involves regular tasks performed at fixed intervals to ensure smooth operation, including oil changes, filter replacements, and general inspections.
Specific Repairs
Specific servicing includes targeted repairs to fix identified issues that do not require a complete overhaul of the system.
Regular Upkeep
Regular upkeep pertains to ongoing activities that maintain the operational quality and enhance the lifespan of machinery.
Special Considerations
Frequency
Maintenance activities can be less frequent but more comprehensive, including extensive overhauls. Servicing is performed more regularly and involves limited, quick tasks.
Depth and Scope
Maintenance could include major component replacements and extensive troubleshooting, while servicing generally involves surface-level tasks to keep equipment running smoothly.
Historical Context
The concept of preventive maintenance began gaining traction during World War II for military equipment reliability. Servicing, being more routine, predates formal maintenance practices, rooted in simple upkeep chores to avoid complete system failure.
Applicability in Various Industries
Manufacturing
Maintenance ensures the longevity of industrial machinery, while servicing keeps production running smoothly with minimal interruptions.
Aviation
Aircraft undergo rigorous maintenance schedules, while servicing includes regular safety checks and refueling.
Automotive
Cars require both maintenance, such as engine overhauls, and servicing, such as oil changes and tire rotations.
Comparisons
| Aspect | Maintenance | Servicing |

Summary
Understanding the differences between maintenance and servicing is crucial for effective management of equipment and systems. While maintenance encompasses a wide range of activities aimed at achieving long-term operational efficiency, servicing focuses on regular and routine tasks to ensure immediate functionality. By integrating both practices, industries can ensure optimal performance and longevity of their assets.
