Heavy Equipment Systems & Diagnostics Handbook: Evidence-Based Troubleshooting, Measurement, and Verification for Diesel, Hydraulics, Drivetrains, Electronics, Networks, and Electric Equipment

Diagnose the system—not just the symptom.

When heavy equipment loses power, overheats, derates, drifts, communicates poorly, or develops
an intermittent fault, replacing parts is not a diagnostic strategy. Heavy Equipment Systems
& Diagnostics Handbook gives technicians a practical, evidence-based method for finding
the cause, proving the repair, and reducing repeat failures.

A field-ready reference for modern heavy equipment

• Diesel engines, fuel systems, air handling, aftertreatment, cooling, lubrication, and
  performance testing
• Mobile hydraulics, pumps, valves, cylinders, hydrostatic drives, pressure/flow testing, and
  contamination control
• Drivetrains, transmissions, axles, brakes, steering, undercarriage, structures, attachments,
  and operator systems
• Electrical and electronic diagnosis, sensors, actuators, voltage-drop testing, J1939/CAN
  networks, and intermittent faults
• Hybrid and battery-electric equipment, high-voltage safety, charging, inverters, traction
  motors, thermal management, and reduced-power diagnosis
• Condition monitoring, trend analysis, fault isolation, case studies, checklists, worked
  examples, and proof-of-repair

Built for technicians who need evidence, not guesswork. Each system is tied to
measurable symptoms, test strategy, expected behavior, root-cause reasoning, and final
verification.

Ideal for heavy-equipment technicians, diesel mechanics, apprentices, instructors, fleet and
maintenance professionals, reliability teams, and serious equipment owners who want one integrated
reference for today’s diesel, hydraulic, electronic, networked, hybrid, and electric machines.
