Caterpillar Technician Course

Lesson 1 • Technical Documentation and Resources

Trains students to navigate Service Manuals, Parts Manuals, and Cat SIS electronic resources. Accurate documentation use is essential for every repair task.

Lesson 2 • Major Systems and Their Functions

Surveys the engine, hydraulic, electrical, powertrain, and undercarriage systems present on Cat machines. Provides the system map used throughout the course.

Lesson 3 • Machine Identification and Nomenclature

Covers model numbering systems, serial number decoding, and component labeling conventions. Enables accurate parts ordering and service record management.

Lesson 1 • Hazardous Materials Handling

Addresses safe handling, storage, and disposal of fuels, oils, coolants, and battery acids. Proper practices protect technicians and meet environmental compliance requirements.

Lesson 2 • Lockout and Tagout Procedures

Details energy isolation steps for hydraulic, electrical, and mechanical systems before service begins. Lockout/tagout compliance is mandatory for all repair operations.

Lesson 3 • Fire Prevention and Emergency Response

Covers fire triangle principles, extinguisher selection, and emergency evacuation protocols for shop environments. Rapid correct response minimizes injury and equipment loss.

Lesson 4 • Machine Stability and Lifting Safety

Teaches safe jack, hoist, and blocking techniques for heavy components and complete machines. Stability failures are a leading cause of fatal shop accidents.

Lesson 1 • Engine Design and Operating Principles

Explains four-stroke diesel combustion, compression ratios, and Cat engine architecture. This foundation supports all fuel, air, and cooling system diagnostics.

Lesson 2 • Fuel System Components and Operation

Covers mechanical and electronic fuel injection systems, high-pressure common rail, and fuel filtration. Fuel system integrity directly determines engine performance and emissions.

Lesson 3 • Air Induction and Exhaust Management

Addresses turbocharger operation, intercooling, air filtration, and exhaust aftertreatment systems. Proper air management maximizes power output and emissions compliance.

Lesson 4 • Engine Cooling and Lubrication Systems

Teaches coolant flow paths, thermostat function, oil pump operation, and oil pressure diagnostics. These systems prevent the most costly engine failures.

Lesson 1 • Control Valves and Actuators

Explains directional, pressure relief, and flow control valves, plus cylinder and motor actuator operation. Valve function determines speed, force, and direction of all work functions.

Lesson 2 • Hydraulic Circuit Reading and Analysis

Trains students to read ISO hydraulic schematic symbols and trace circuit paths for Cat machines. Schematic fluency is required before any system-level diagnosis.

Lesson 3 • Hydraulic System Troubleshooting

Applies pressure and flow testing, contamination analysis, and systematic fault isolation to real hydraulic faults. Students use Cat diagnostic procedures to restore system function.

Lesson 4 • Hydraulic Pumps and Motors

Covers gear, piston, and vane pump designs, variable displacement control, and hydraulic motor operation. Pump condition directly determines system pressure and flow capacity.

Lesson 1 • Electronic Control Module Diagnostics

Teaches ECM function, flash programming, fault code retrieval, and parameter configuration using Cat ET software. ECM diagnostics resolve the majority of modern Cat machine faults.

Lesson 2 • Sensors, Actuators, and Data Links

Explains pressure, temperature, speed, and position sensors, plus CAN data link architecture on Cat machines. Sensor accuracy is the foundation of electronic control system performance.

Lesson 3 • Charging and Starting System Service

Covers alternator output testing, battery load testing, starter motor diagnosis, and circuit repair. Reliable starting and charging are critical for machine availability.

Lesson 4 • Cat Electrical Schematic Interpretation

Covers Cat wiring diagram conventions, connector identification, and harness routing documentation. Accurate schematic reading prevents misdiagnosis and unnecessary parts replacement.

Lesson 1 • Final Drive and Axle Inspection

Covers planetary final drive disassembly, gear and bearing inspection, and oil level verification. Final drives transmit maximum torque and require precise reassembly.

Lesson 2 • Brake System Diagnosis and Adjustment

Explains service brake, parking brake, and retarder operation, plus adjustment and wear measurement. Brake system integrity is a primary machine safety requirement.

Lesson 3 • Differential and Bevel Gear Service

Addresses differential carrier inspection, bevel gear contact pattern, and bearing preload adjustment. Correct gear mesh prevents premature failure under heavy load.

Lesson 4 • Torque Converter Operation and Service

Explains torque multiplication, stall speed, lockup clutch function, and converter fluid diagnostics. Torque converter condition directly affects machine acceleration and fuel efficiency.

Lesson 1 • Undercarriage Wear Measurement

Teaches Cat Undercarriage Management System measurement procedures for all wear surfaces. Accurate measurement data drives cost-effective replacement decisions.

Lesson 2 • Track Tension and Adjustment

Covers correct track sag measurement, grease cylinder adjustment, and tension verification for soil conditions. Improper tension accelerates wear and increases fuel consumption.

Lesson 3 • Undercarriage System Components

Identifies track chains, links, pins, bushings, rollers, idlers, and sprockets on Cat track-type machines. Component recognition is required before any wear measurement can begin.

Lesson 4 • Ground Engaging Tool Selection and Wear

Addresses bucket tooth systems, cutting edge selection, and wear indicator monitoring for Cat work tools. Correct GET selection maximizes productivity and minimizes structural damage.

Lesson 1 • Cat Electronic Technician Advanced Functions

Explores Cat ET data logging, snapshot capture, and system calibration routines beyond basic fault code reading. Advanced ET use resolves intermittent and multi-system faults efficiently.

Lesson 2 • Preventive Maintenance Program Management

Covers PM interval scheduling, inspection checklists, fluid and filter change procedures, and maintenance record keeping. A disciplined PM program is the primary driver of machine longevity.

Lesson 3 • Fluid Analysis and Contamination Control

Covers S·O·S fluid sampling procedures, lab report interpretation, and corrective action planning. Fluid analysis detects internal wear before catastrophic failure occurs.

Lesson 4 • Cat Product Link and Telematics

Teaches Product Link installation, VisionLink data interpretation, and remote fault monitoring workflows. Telematics data enables proactive maintenance scheduling and reduces unplanned downtime.
