Covers grease guns, oil cans, centralized systems, and automatic lubricators. Students service and troubleshoot each delivery method to ensure consistent lubricant supply.

Lesson 1 • Hydraulic Pumps and Motors

Identifies gear, vane, and piston pump designs and their performance characteristics. Students measure pump efficiency and recognize signs of internal wear.

Lesson 2 • Hydraulic Principles and Circuit Basics

Covers Pascal's law, flow, pressure, and power relationships in hydraulic circuits. These principles form the analytical basis for all hydraulic diagnosis tasks.

Lesson 3 • Hydraulic System Troubleshooting

Applies a structured diagnostic method to identify pressure loss, overheating, and erratic motion faults. Students use gauges and flow meters to isolate faulty components.

Lesson 4 • Control Valves and Actuators

Explains directional, pressure, and flow control valves and their role in circuit control. Correct valve adjustment ensures safe and precise actuator movement.

Lesson 1 • Air Preparation and Distribution

Covers compressors, dryers, filters, regulators, and lubricators in the air supply chain. Properly conditioned air prevents valve and actuator failures downstream.

Lesson 2 • Pneumatic Circuit Troubleshooting

Applies leak detection, pressure testing, and logic tracing to diagnose pneumatic faults. Systematic diagnosis minimizes downtime and prevents repeat failures.

Lesson 3 • Pneumatic Valves and Actuators

Identifies directional, flow, and pressure control valves and pneumatic cylinder configurations. Students connect and adjust valves to achieve specified actuator motion profiles.

Lesson 1 • Electric Motors and Starters

Covers induction motor construction, nameplate data, and starter circuit operation. Mechanics learn to check motor insulation and replace contactors and overload relays.

Lesson 2 • DC and AC Circuit Fundamentals

Reviews Ohm's law, series and parallel circuits, and AC waveform characteristics. These concepts enable mechanics to interpret wiring diagrams and meter readings accurately.

Lesson 3 • Sensors and Control Devices

Identifies proximity, photoelectric, and limit switch sensors used in automated machinery. Correct sensor alignment and wiring ensure reliable machine cycle control.

Lesson 4 • Introduction to PLC Operation

Explains PLC hardware, I/O modules, and basic ladder logic for maintenance purposes. Mechanics use PLC status indicators to identify faults without programming knowledge.

Lesson 1 • Vibration Analysis Basics

Introduces vibration frequency, amplitude, and phase as indicators of mechanical faults. Mechanics use handheld analyzers to detect imbalance, misalignment, and looseness.

Lesson 2 • Precision Measurement and Inspection

Uses surface plates, height gauges, and coordinate measuring to verify assembled dimensions. Inspection data confirms that assemblies meet design specifications before commissioning.

Lesson 3 • Geometric Dimensioning and Tolerancing

Applies GD&T symbols to interpret flatness, roundness, and positional tolerances on drawings. Accurate interpretation prevents assembly errors and costly rework.

Lesson 4 • Balancing Rotating Components

Explains static and dynamic imbalance and the correction methods used on fans and rotors. Balanced rotating parts reduce bearing loads and extend machine service life.

Lesson 1 • Condition Monitoring Techniques

Applies vibration, thermography, ultrasound, and oil analysis to detect developing faults. Early fault detection allows planned repairs before failures cause production losses.

Lesson 2 • Maintenance Strategy Overview

Compares reactive, preventive, predictive, and reliability-centered maintenance strategies. Selecting the right strategy for each asset type optimizes cost and availability.

Lesson 3 • Computerized Maintenance Management

Introduces CMMS work order creation, asset history, and spare parts management functions. Accurate records improve planning, reduce inventory costs, and support audits.

Lesson 4 • Root Cause Analysis Methods

Applies the five-whys and fishbone diagram methods to identify failure root causes. Eliminating root causes prevents recurrence and reduces overall maintenance costs.
