Kubota LA402ST Front Loader Parts Manual (BKIDK0624)

The Kubota LA402ST is a front loader that hangs off the front of a compact tractor, the one you’re using for pallet forks, manure, gravel, and feed. The Kubota LA402ST parts manual (BKIDK0624) is what parts counters and field techs grab when they’re trying to nail down the exact pin, bushing, cylinder seal kit, or bracket before the machine is torn apart. If you’re trying to keep loader downtime short during planting or harvest, this is the book you use to see how it’s built and what to order.

What this manual helps you do

• Identify the correct OEM part numbers for loader arms, bucket linkage, pins, and bushings on the Kubota LA402ST front loader.
• Locate every hydraulic cylinder component on the loader—rods, glands, seals, and hoses—using exploded diagrams before you start a rebuild.
• Look up hardware, shims, grease fittings, and small parts by quantity-per-loader so you don’t come up short mid-job.
• Cross-reference older Kubota part numbers to newer superseded numbers shown in the parts listings, to match what the dealer’s system now uses.
• Verify that the bucket, quick-attach, and related brackets you’re ordering are the right ones for the LA402ST, not a similar-looking loader model.

Who this is for

This Kubota LA402ST parts manual is aimed at independent ag mechanics, farm owner‑operators, and Kubota dealer parts staff who need accurate loader part numbers fast. If you’re looking for torque specs, hydraulic pressure checks, or step‑by‑step repair procedures, you’ll want the Kubota workshop/service manual instead, not this parts catalog.
