Letourneu L-1850 Gen1 Wheel Loader Technical Training

The L-1850 is a big quarry and mine loader, living in rock piles, shot faces and muck, not on smooth concrete. This training manual helps newer techs understand how the machine is laid out—mechanically, electrically and electronically—so they can think their way through faults instead of just swapping parts. For example, if the loader won’t propel after a shutdown, this guide helps you trace the propulsion and SCR-related systems step by step, verify signals, and decide whether you’re dealing with a control issue, a sensor, or a wiring problem.

Applications & Use Cases

• Build a mental map of major systems so you can walk around the loader and know what you’re looking at and why it matters.
• Practice safe diagnostic habits on paper or in a classroom before you ever open a panel on a live machine.
• Learn to trace circuits and fluid paths logically, so you can isolate faults faster in the pit.
• Use the walk-around concepts to plan inspections, spot small issues early, and talk clearly with operators.
• Strengthen your ability to read diagrams, relate them to real components, and plan test steps instead of guessing.

FAQ

Q: Can I use this on a tablet in the field?

A: Yes, it’s well-suited to a tablet or laptop so you can zoom diagrams and review procedures right beside the machine.

Q: Is it still worth printing parts of it?

A: Printing key diagrams and checklists is handy for toolbox talks, training new hires, and marking your own notes as you learn the systems.

Safety Note

Always treat this manual as guidance and back it up with site rules, lockout procedures, and the latest manufacturer safety information before touching the machine.
