Mechanical Maintenance Course

Lesson 1 • Maintenance Record Keeping

Explains work order systems, maintenance logs, and failure history tracking. Proper records support trend analysis and regulatory compliance.

Lesson 2 • Reading Technical Documentation

Teaches interpretation of equipment manuals, schematics, and parts lists. Accurate documentation reading is essential for all subsequent repair tasks.

Lesson 3 • Introduction to Industrial Machinery

Covers machine classifications, primary components, and operational roles in production environments. Provides the baseline vocabulary needed throughout the course.

Lesson 4 • Maintenance Categories and Strategies

Defines reactive, preventive, predictive, and proactive maintenance types. Connects strategy selection to equipment reliability and cost outcomes.

Lesson 1 • Precision Measuring Instruments

Introduces calipers, micrometers, dial indicators, and feeler gauges for dimensional inspection. Measurement accuracy directly determines repair quality.

Lesson 2 • Common Hand Tools for Machinery Work

Covers wrenches, screwdrivers, hammers, pliers, and specialty tools used in machinery maintenance. Correct tool selection prevents component damage and injury.

Lesson 3 • Tool Care and Calibration

Covers cleaning, storage, inspection, and calibration schedules for hand tools and instruments. Well-maintained tools ensure consistent measurement and operational safety.

Lesson 1 • Gear Systems and Gearboxes

Explains spur, helical, bevel, and worm gear types along with gearbox inspection procedures. Gear wear patterns indicate lubrication and alignment problems.

Lesson 2 • Belt, Chain, and Sprocket Drives

Addresses V-belt, flat belt, synchronous belt, and roller chain drive systems. Proper tensioning and alignment extend drive life significantly.

Lesson 3 • Shafts, Keys, and Couplings

Examines shaft types, keyways, and coupling designs used to transmit torque between components. Misalignment and key failure are primary failure modes addressed.

Lesson 4 • Shaft Alignment Techniques

Teaches dial indicator and laser alignment methods for coupled shafts. Misalignment causes premature bearing and seal failure, making this skill critical.

Lesson 1 • Hydraulic Fluid Systems

Covers hydraulic fluid types, reservoir maintenance, and system cleanliness standards. Hydraulic systems are highly sensitive to contamination and fluid degradation.

Lesson 2 • Lubricant Types and Properties

Covers mineral oils, synthetic lubricants, greases, and solid lubricants with their viscosity and additive characteristics. Correct lubricant selection is the foundation of any lubrication programme.

Lesson 3 • Lubrication Application Methods

Explains manual greasing, oil bath, splash, forced circulation, and automatic lubrication systems. Method selection depends on component speed, load, and accessibility.

Lesson 4 • Developing a Lubrication Programme

Guides creation of lubrication routes, intervals, and documentation aligned with equipment requirements. A structured programme reduces unplanned failures and lubricant waste.

Lesson 1 • Reading Electrical Schematics

Teaches ladder diagrams, wiring diagrams, and control circuit symbols used in industrial machinery. Schematic literacy is required for all electrical troubleshooting tasks.

Lesson 2 • Motor Control and Protection Devices

Explains contactors, overload relays, variable frequency drives, and soft starters. Proper device settings protect motors and extend their operational life.

Lesson 3 • Electric Motors: Types and Maintenance

Covers AC induction, DC, and servo motor construction, nameplate data, and maintenance tasks. Motors are the primary drivers of industrial machinery and require regular inspection.

Lesson 4 • Electrical Troubleshooting Techniques

Applies multimeter, clamp meter, and megohmmeter measurements to diagnose open circuits, shorts, and ground faults. Systematic fault isolation reduces diagnostic time.

Lesson 1 • Pneumatic System Troubleshooting

Diagnoses low pressure, excessive leakage, slow actuation, and valve malfunction in pneumatic circuits. Leak detection and flow testing are primary diagnostic tools.

Lesson 2 • Hydraulic System Troubleshooting

Applies pressure gauge, flow meter, and temperature measurement to isolate hydraulic faults. Systematic testing prevents unnecessary component replacement.

Lesson 3 • Pneumatic System Fundamentals

Covers compressed air generation, FRL units, directional valves, and pneumatic actuators. Pneumatic systems require clean, dry, regulated air for reliable operation.

Lesson 4 • Hydraulic and Pneumatic Component Repair

Covers seal replacement, valve rebuilding, and pump and cylinder overhaul procedures. Component-level repair skills reduce reliance on full unit replacement.

Lesson 1 • Gasket Materials and Selection

Explains compressed fibre, metallic, spiral-wound, and elastomeric gasket types. Material compatibility with fluid and temperature determines gasket service life.

Lesson 2 • Leak Detection and Diagnosis

Covers visual inspection, dye testing, pressure testing, and ultrasonic leak detection methods. Accurate leak location minimises repair time and fluid loss.

Lesson 3 • Seal and Gasket Installation

Teaches surface preparation, installation tools, and torque sequences for leak-free joints. Improper installation is the leading cause of premature seal failure.

Lesson 1 • Oil Analysis and Wear Debris Monitoring

Explains viscosity testing, particle counting, spectrometric analysis, and ferrography for in-service oil. Oil analysis identifies component wear before catastrophic failure.

Lesson 2 • Infrared Thermography for Maintenance

Covers thermal camera operation, emissivity settings, and interpretation of thermal images for electrical and mechanical faults. Heat patterns indicate overloaded or failing components.

Lesson 3 • Building a Condition Monitoring Programme

Guides route creation, data collection frequency, alarm limit setting, and reporting for a plant-wide programme. A structured programme converts data into actionable maintenance decisions.

Lesson 4 • Ultrasound Inspection Techniques

Applies airborne and structure-borne ultrasound to detect leaks, bearing defects, and electrical discharge. Ultrasound complements vibration analysis for early fault detection.
