Industrial Mechanic Course

Lesson 1 • Workplace Safety and Hazard Control

Covers lockout/tagout, PPE selection, and hazard identification in industrial settings. Anchors all subsequent hands-on work in a safety-first mindset.

Lesson 2 • Hand Tools and Measuring Instruments

Teaches proper selection, use, and care of wrenches, hammers, and precision measuring tools. Accurate measurement is prerequisite to all alignment and assembly tasks.

Lesson 3 • Introduction to Fasteners and Joining

Explains bolt grades, thread standards, and torque specifications for mechanical joints. Proper fastener selection prevents failures in all assembled systems studied later.

Lesson 4 • Reading Technical Drawings

Develops ability to interpret orthographic views, tolerances, and assembly diagrams. Blueprint literacy is required for every installation and repair task in the course.

Lesson 1 • Grease and Oil Application Methods

Covers manual and automatic lubrication delivery, intervals, and quantities for bearings and gears. Correct application directly reduces bearing failures addressed in Chapter 3.

Lesson 2 • Hydraulic Fluid Properties and Selection

Examines hydraulic fluid types, compatibility, and contamination control. Fluid quality directly affects the hydraulic components studied in Chapter 5.

Lesson 3 • Seals, Gaskets, and Leak Prevention

Identifies seal materials, installation methods, and common failure modes in fluid systems. Leak-free assemblies are essential for safe hydraulic and lubrication circuits.

Lesson 1 • Bearing Failure Analysis

Identifies spalling, brinelling, and corrosion patterns to determine root causes of bearing damage. Failure analysis skills prevent repeat failures and guide maintenance decisions.

Lesson 2 • Bearing Installation and Removal

Teaches interference fits, heating methods, and puller techniques for safe bearing handling. Proper installation preserves the tolerances established during shaft machining.

Lesson 3 • Shaft Inspection and Repair

Covers runout measurement, keyway inspection, and surface restoration of worn shafts. Shaft integrity is prerequisite to reliable bearing and coupling performance.

Lesson 4 • Flexible and Rigid Couplings

Explains coupling types, torque ratings, and installation requirements for shaft connections. Coupling selection affects the alignment procedures covered in Chapter 4.

Lesson 1 • Dial Indicator Alignment Methods

Applies rim-and-face and reverse-dial methods to calculate and correct shaft misalignment. Dial methods build manual precision before laser tools are introduced.

Lesson 2 • Documenting and Verifying Alignment

Records pre- and post-alignment data and confirms results meet operational tolerances. Documentation supports predictive maintenance programmes introduced in Chapter 8.

Lesson 3 • Laser Alignment Systems

Operates laser alignment instruments to measure and correct horizontal and vertical offsets. Laser tools provide faster, more repeatable results than dial methods alone.

Lesson 4 • Alignment Theory and Misalignment Types

Defines parallel, angular, and combined misalignment and their effects on machinery. Theory provides the diagnostic framework for all alignment correction methods.

Lesson 1 • Hydraulic Circuit Fundamentals

Explains Pascal's law, pressure, flow, and power relationships in hydraulic circuits. Circuit theory is the foundation for component diagnosis and system troubleshooting.

Lesson 2 • Pneumatic System Components

Examines compressors, air treatment units, and pneumatic actuators used in industrial automation. Pneumatic systems share control logic with hydraulics but require different maintenance practices.

Lesson 3 • Hydraulic Pumps and Motors

Covers gear, vane, and piston pump operation, efficiency, and common failure modes. Pump and motor health directly determines system output and energy consumption.

Lesson 4 • Hydraulic Valves and Actuators

Identifies directional, pressure, and flow control valves and their roles in circuit control. Valve function knowledge enables accurate fault isolation during troubleshooting.

Lesson 1 • Variable-Speed Drive Systems

Explains mechanical variable-speed drives and introduces variable-frequency drive interfaces. Speed control knowledge prepares students for process-integrated maintenance tasks.

Lesson 2 • Gear Types and Gearbox Operation

Classifies spur, helical, bevel, and worm gears by application and load characteristics. Gear geometry knowledge supports gearbox inspection and oil analysis interpretation.

Lesson 3 • Gearbox Overhaul Procedures

Guides complete disassembly, inspection, bearing replacement, and reassembly of industrial gearboxes. Overhaul integrates bearing, lubrication, and alignment skills from earlier chapters.

Lesson 4 • Chain Drive Maintenance

Addresses roller chain selection, lubrication, elongation measurement, and sprocket wear. Chain drives are common in conveyors and mixers requiring scheduled inspection.

Lesson 1 • Ultrasound and Motor Current Analysis

Applies ultrasonic detection to find bearing defects, leaks, and electrical discharge. Motor current analysis identifies rotor and stator faults without motor removal.

Lesson 2 • Maintenance Metrics and Reporting

Calculates OEE, MTBF, and MTTR to evaluate maintenance programme effectiveness. Metrics-driven reporting supports the strategic planning skills developed in Chapter 8.

Lesson 3 • Thermography and Oil Analysis

Uses infrared cameras and oil sampling to detect electrical hot spots and lubricant degradation. Non-invasive monitoring extends equipment life without unnecessary disassembly.

Lesson 4 • Preventive Maintenance Programme Design

Defines PM task types, frequencies, and resource requirements for rotating and static equipment. A well-designed PM programme reduces unplanned downtime across all systems studied.

Lesson 1 • Reliability-Centred Maintenance

Introduces RCM logic to select the most effective maintenance strategy for each failure mode. RCM optimises PM tasks developed in Chapter 7 based on consequence and probability.

Lesson 2 • Machine Overhaul Planning and Execution

Manages scope definition, parts procurement, and execution sequencing for major overhauls. Overhaul planning integrates gearbox, hydraulic, and alignment skills from all prior chapters.

Lesson 3 • Root Cause Analysis Methods

Applies 5-Why, fishbone, and fault tree analysis to mechanical failure investigations. Structured RCA prevents recurrence and supports continuous improvement culture.

Lesson 4 • Advanced Vibration Diagnostics

Interprets complex spectra for gear mesh, bearing defect frequencies, and structural resonance. Advanced diagnostics extend the vibration fundamentals introduced in Chapter 7.
