Industrial Machinery Maintenance Course

Lesson 1 • Regulatory Compliance Fundamentals

Explains how workplace safety regulations, inspection records, and incident reporting apply to maintenance teams. Compliance protects workers and avoids operational shutdowns.

Lesson 2 • Lockout/Tagout Procedures

Details energy isolation steps for electrical, hydraulic, pneumatic, and thermal sources. Proper lockout/tagout prevents accidental machine startup during service.

Lesson 3 • Confined Space and Elevated Work Safety

Addresses permit requirements, atmospheric testing, and fall protection for high-risk work areas. These controls are mandatory before entering or working at height.

Lesson 4 • Personal Protective Equipment

Guides selection, inspection, and correct use of PPE for common maintenance environments. Matching PPE to specific hazards reduces injury risk.

Lesson 1 • Electrical Systems in Machinery

Introduces motors, control panels, sensors, and wiring fundamentals relevant to maintenance. Provides the electrical literacy needed for safe troubleshooting.

Lesson 2 • Core Mechanical Components

Covers shafts, bearings, gears, couplings, and fasteners as fundamental building blocks. Understanding these parts is prerequisite for all maintenance tasks.

Lesson 3 • Industrial Machinery Overview

Introduces major categories of industrial machines and their roles in production. Establishes vocabulary used throughout the course.

Lesson 4 • Fluid Power Fundamentals

Explains hydraulic and pneumatic principles that drive actuators and controls. Connects fluid power concepts to machine motion and force transmission.

Lesson 1 • Precision Measurement Instruments

Teaches use of calipers, micrometers, dial indicators, and feeler gauges for dimensional checks. Accurate measurement is the basis for fit, tolerance, and alignment decisions.

Lesson 2 • Hand Tools for Maintenance

Covers wrenches, screwdrivers, pliers, hammers, and specialty tools with correct usage techniques. Proper tool selection prevents fastener damage and personal injury.

Lesson 3 • Alignment and Leveling Tools

Covers straightedges, precision levels, laser aligners, and dial indicator rigs for shaft alignment. Correct alignment extends bearing and coupling life significantly.

Lesson 4 • Tool Care and Calibration

Explains cleaning, storage, calibration schedules, and out-of-tolerance procedures for all tools. Calibrated tools ensure measurement reliability and regulatory compliance.

Lesson 1 • Filter, Belt, and Fluid Service

Details replacement intervals and procedures for filters, drive belts, and hydraulic or coolant fluids. Timely service of consumables prevents secondary component damage.

Lesson 2 • PM Scheduling and Work Orders

Teaches how to build PM schedules, generate work orders, and track completion in a maintenance system. Scheduling discipline converts PM plans into consistent executed actions.

Lesson 3 • Lubrication Management

Covers lubricant types, viscosity selection, application methods, and contamination control. Correct lubrication is the single highest-impact PM activity for most machines.

Lesson 4 • Preventive Maintenance Principles

Defines PM goals, cost-benefit logic, and the difference between time-based and usage-based intervals. This framework guides all scheduling decisions in the chapter.

Lesson 1 • Gearbox and Reducer Service

Covers gearbox inspection, oil analysis, seal replacement, and gear wear evaluation. Gearbox health directly impacts torque delivery and downstream equipment reliability.

Lesson 2 • Seals, Gaskets, and Packing

Addresses static and dynamic seal types, surface preparation, and correct installation to prevent leaks. Seal integrity is critical for fluid containment and machine longevity.

Lesson 3 • Bearing Maintenance and Replacement

Covers bearing removal, inspection, selection, installation, and preload adjustment. Bearings are the most frequently replaced mechanical component in industrial machinery.

Lesson 4 • Belt, Chain, and Gear Drives

Teaches inspection, tensioning, alignment, and replacement of V-belts, chains, and gear sets. Drive system condition directly affects power transmission efficiency and component life.

Lesson 1 • Hydraulic Fluid Management

Addresses fluid cleanliness standards, contamination sources, filtration, and fluid change procedures. Fluid quality is the primary driver of hydraulic component service life.

Lesson 2 • Pressure Testing and Performance Verification

Teaches gauge installation, pressure and flow testing, and comparison against design specifications. Verification confirms that repaired circuits meet original performance requirements.

Lesson 3 • Hydraulic Circuit Inspection

Teaches systematic visual and pressure-based inspection of pumps, valves, cylinders, and hoses. Circuit inspection is the starting point for all hydraulic fault diagnosis.

Lesson 4 • Pneumatic System Maintenance

Details air preparation units, valve service, cylinder maintenance, and leak detection in pneumatic circuits. Clean, dry, regulated air is essential for reliable pneumatic operation.

Lesson 1 • Electrical Safety and Isolation

Reinforces arc flash awareness, voltage testing, and electrical lockout before any panel work. Electrical isolation is non-negotiable before touching live circuit components.

Lesson 2 • Motor Inspection and Testing

Covers winding resistance, insulation resistance, and current draw tests for AC and DC motors. Motor testing identifies degradation before catastrophic winding failure occurs.

Lesson 3 • Control Panel and Wiring Maintenance

Teaches terminal tightening, contactor inspection, relay testing, and wire labelling in control panels. Panel integrity prevents nuisance trips and unplanned production stops.

Lesson 4 • Variable Frequency Drive Maintenance

Addresses VFD inspection, parameter verification, cooling system service, and fault code interpretation. VFDs control motor speed and torque, making their reliability critical.

Lesson 1 • Reliability-Centered Maintenance Strategy

Applies RCM logic to select the best maintenance strategy for each failure mode based on consequence and detectability. RCM aligns maintenance effort with actual risk and business impact.

Lesson 2 • Thermographic Inspection

Covers infrared camera operation, emissivity settings, and thermal pattern interpretation for electrical and mechanical components. Thermal anomalies reveal overloads and friction before failure.

Lesson 3 • Vibration Analysis Fundamentals

Explains vibration measurement, frequency spectra, and common fault signatures for rotating equipment. Vibration data is the most widely used predictive maintenance indicator.

Lesson 4 • Oil and Lubricant Analysis

Teaches sampling procedures, laboratory report interpretation, and corrective actions based on wear metal and contamination data. Oil analysis extends component life and prevents unplanned failures.
