LeTourneau L-1850 Wheel Loader Parts Manual (Joy Global) (SN 2065)

The L-1850 is a big loader that lives in mines and quarries, moving rock all day in dust, mud, and cold. This parts manual is what I use to match every component on that machine to the correct Joy/LeTourneau part number, especially on this specific serial number 2065. When we tear into a structural section or pull a power-unit component and the tag is gone or unreadable, this book lets us visually trace what we’ve got on the floor back to the right listing before we order anything.

Applications & Use Cases

• Confirm part numbers after teardown so the rebuilt assemblies go back together with the correct hardware and subcomponents.
• Trace component relationships in the structural and drive areas to see what else should be inspected or replaced while it’s open.
• Isolate running changes tied to this serial number so you don’t order parts that only fit earlier or later machines.
• Verify small fittings, brackets, and fasteners that are easy to mix up when several systems are apart at once.
• Plan parts orders ahead of a shutdown by walking the machine and cross-checking what you see with the illustrated listings.

FAQ

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

A: Yes, it’s practical to keep a digital copy on a tablet or laptop so you can zoom in on diagrams right beside the loader.

Q: Is it worth printing sections of this manual?

A: Many shops print the diagrams and parts lists for the area they’re working on, mark them up during teardown, then file them with the work order.

Safety Note

Always lock out, tag out, and verify zero energy before inspecting or matching parts on the loader.
