Kubota LA402 Front Loader Parts Manual

The Kubota LA402 is the factory front loader you’ll see hanging off a lot of compact Kubota tractors, the kind of setup like I’ve got on my own L-series. The Kubota LA402 parts manual is what I grab when I’m trying to figure out exactly which pin, bushing, or seal kit I need before I start tearing things apart on a Saturday. Folks who reach for this are usually farm owner-operators, independent mechanics, or anyone tired of guessing at parts at the dealer counter. If you’re trying to plan a loader cylinder reseal, fix a sloppy pivot, or order the right brackets and hoses, this is the book.

What this manual helps you do

• Identify every OEM part used in the LA402 loader arms, boom, bucket linkage, and mounts so you can order exactly what fits your loader.
• Locate the correct pins, bushings, and wear plates when you’re chasing down slop in the pivot points instead of buying random hardware.
• Look up hydraulic cylinder internals (rods, glands, seal kits, snap rings) using exploded diagrams before you pull the cylinder off the tractor.
• Cross-reference older Kubota part numbers shown for the LA402 to the updated numbers your dealer’s computer now uses.
• Verify which hoses, hard lines, brackets, and loader stands belong to the LA402 setup so you don’t end up mixing parts from a different loader model.

Who this is for

This parts manual is aimed at a farm owner-operator, independent ag mechanic, or Kubota parts counter person who needs correct LA402 loader part numbers and diagrams. If you’re hunting for torque specs, repair procedures, or how-to steps, you want the Workshop/Service Manual, not this parts catalog.
