Letourneau L1350 Wheel Loader Complete Service, Parts, Training, Schematics Package

The L1350 is a big production loader, usually living in mines and quarries, loading trucks all day in dust, cold, and heat. This package gives you the system-level view—hydraulic, electrical, and mechanical—so you can trace how one component affects the next. When the boom creeps down, a fan won’t cut in, or the machine won’t move after a shutdown, this is what I’d use to follow the schematics, isolate the fault, and confirm I’ve got the right parts before tearing anything apart.

Applications & Use Cases

Trace hydraulic and electrical circuits end‑to‑end to pinpoint a weak valve, sensor, or connector.
Cross‑check part numbers against the diagrams before ordering or swapping components.
Use the training material to practice reading schematics and fault tracing before touching a live machine.
Plan a safe rebuild by seeing how major components are routed, supported, and interconnected.
Verify correct hose, harness, and linkage routing after repairs to avoid chafing and misalignment.

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 into schematics while you’re standing at the machine.

Q: Is it worth printing sections of this package?

A: Many techs print the key schematics and parts diagrams, laminate them, and keep them in the service truck for quick reference.

Safety Note

Always de‑energize, support, and relieve stored pressure on the loader before using this manual to perform any inspection or repair.
