LeTourneau L2350 Parts Manual

On an L2350 that spends its life in mines or big quarries, everything is oversized and buried in dust, so guessing at parts is expensive. This parts manual is what I’d keep open while the loader is torn down, so every bolt-on item I pull off can be matched to the right illustration and part number. If, for example, you’re chasing an oil leak around the crankcase and end housing, this lets you trace each gasket, seal, and bracket you’ve removed and order exactly what you need to put it back together once, not twice.

Applications & Use Cases

• Match teardown parts from the engine area—crankcase, oil pan, mounts—to the correct part numbers before writing a parts list.
• Differentiate similar components (brackets, covers, breathers) so you don’t mix early/late or left/right pieces when reassembling.
• Verify hardware and small items like labels and auxiliary materials that often get missed but are needed to finish the job cleanly.
• Support troubleshooting by tracing related components in a system, helping you see what else should be inspected or replaced while you’re in there.
• Communicate with the parts department using the same reference images and numbering logic to avoid wrong shipments and downtime.

FAQ

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

A: Yes, it’s practical to zoom into the exploded views on a tablet so you can match parts right at the machine.

Q: Is it worth printing sections of this manual?

A: Many techs print the relevant assemblies before a big teardown so the pages can get greasy without risking the main file.

Safety Note

Always lock out, tag out, and properly support all components before inspecting or removing any parts identified from this manual.
