Letourneau L-2350 Gen2 Wheel Loader Service Manual (SN 2235)

On a machine this size, working face to crusher all day in dust, heat, and mud, you can’t afford guesswork. This service manual is what I use to trace faults and confirm failures on the L-2350 Gen2 before we start pulling major components. For example, if the loader comes in with weak lift and a hydraulic warning, this book walks me through how to verify the issue step by step instead of just throwing a valve bank at it.

Applications & Use Cases

• Isolate hydraulic problems by following the test and adjustment sequences before replacing pumps, motors, or cylinders.
• Track down electrical faults in controls and interlocks using the documented logic paths and check procedures.
• Plan disassembly and reassembly of large components so you know which guards, lines, and supports to remove in a safe order.
• Verify adjustments on linkages, brakes, and steering so the loader tracks straight and responds correctly under load.
• Confirm root cause of fault codes or warning lamps before ordering expensive parts to a remote site.

FAQ

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

A: Yes, it’s practical to keep it on a tablet so you can zoom diagrams and follow steps right next to the machine.

Q: Is it worth printing sections of this manual?

A: I usually print the procedures I’m using that day, so they can get dirty in the cab or shop without risking the main file.

Safety Note

Always lock out, support, and relieve stored energy exactly as described before putting hands or tools on this loader.
