LeTourneau L2350 Wheel Loader Complete Service, Parts, Schematics, Training, Operator Handbook

On a big L2350 working in a mine or large quarry, you’re dealing with huge loads, bad footing, and long shifts. This combined service, parts, schematic, training, and operator handbook is what I’d keep on hand to trace systems from the cab controls right down to the components buried in the frame. If, for example, the loader starts losing lift power under a full bucket on a ramp, I’d use this to follow the hydraulic circuit, verify control logic, and confirm I’m ordering the right parts before I ever pull a hose or valve.

Applications & Use Cases

• Trace hydraulic and electrical faults across the whole machine using the schematics, instead of guessing at hidden harness routes or valve locations.
• Plan and verify repairs by cross‑checking component IDs with the parts info so you don’t pull the wrong cylinder, hose, or sensor.
• Train new operators and techs on proper warm‑up, shutdown, and loading habits that reduce abuse on uneven ground and tight faces.
• Improve bucket control under load by understanding how the controls are supposed to respond and what to check when they feel sluggish or jumpy.
• Set up daily inspections that actually catch cracks, leaks, and loose hardware before they turn into downtime.

FAQ

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

A: Yes, it’s practical to keep it on a tablet or laptop so you can zoom schematics and parts views right beside the machine.

Q: Is it worth printing any of it?

A: Many techs print key schematics and wear them in plastic sleeves for quick tracing and notes in the workshop.

Safety Note

Always lock out, support, and block the loader safely before inspecting or working under any raised component.
